Moral ontology

A while back I wrote a post titled “What is a moral claim” that did not do a good job of getting at the heart of the topic I was actually aiming to address. So I wanted to recalibrate and go beyond asking “what is a moral claim” by offering an answer. That has turned into a rather thoroughgoing presentation of what I now consider to be the moral ontology which is most likely true. Sorry for the length, but I hope its worth the effort.

First, some moral epistemology

This is what your conscience looks like

I am of the opinion that epistemology should inform ontology (and vice versa). In other words, understanding how it is that we know about something should play a role in defining what we think that something is. Likewise, our understanding of what something is should play a role in defining how it is that we know about it (I covered this more generally in My Ontology – Part 1). I have found that the discussion of morality, particularly in the God debate, often focuses on moral ontology – we like to talk about what morality is without giving too much thought to the epistemology. By asking “What is a moral claim?” in that post last year I was aiming to explore how moral epistemology might inform our moral ontology – contra William Lane Craig, who suggests we should just posit our desired moral ontology and then define our epistemology as a follow-on.

My assertion in that original post was that we can recognize moral claims, and distinguish them from other claims, and that this tells us something about the nature of morality. As was noted by several commenters, this supports nothing more than the notion that morality is at minimum a distinct mental concept. However, I was aiming for something more…

The moral referent

In one of the comments on that original post Dave compared morality to beauty, to which I replied by noting that:

“This is the question of the referent. For beauty, we can generally link the shared concept to ‘the way we feel about certain sensory perceptions’, like sunsets, music, etc…. There is a class of experiences which trigger a similar response in us and so we call those things beautiful.”

This gets to the heart of the matter. As with beauty, there must be some referent which shapes the concept of morality and, as with beauty, it appears that the best we can do is to introspectively trace this to a particular feeling. Just as the concept of “tree” is informed purely by the phenomenal experience of trees (and not through some special metaphysical access to the abstract ideal tree) the concept of beauty is informed by the phenomenal experience of conditions which trigger a particular feeling. Isn’t it most reasonable – perhaps even obvious – that morality is no different?

But there are trees out there in the real world which are separate from our phenomenal experience of them. What is the corresponding reality which feeds into the concept of morality?

When I presented my ontology, I identified universals as mental concepts which are constructed as generalizations of our experience of particulars. The particulars which inform a universal need not be mind-independent, objective entities. Despite the connotations of our language (e.g., “that’s a beautiful sunset”), most of us are not inclined to actually assign beauty as an intrinsic property of the object of our perception, but we rather accept it as a subjective component of our experience; beauty is in the eye of the beholder. Likewise, we’re all familiar with the concept of sadness, but not because it exists ‘out there’ in some sense, but because we are all human and have been able to relate a similar internal state to a common idea which we can communicate. My proposal is that morality is like beauty and sadness. Morality is informed by my phenomenal experience of the feelings and intuitions which arise under certain circumstances.

I take it that the view I have presented for sadness and beauty is fairly uncontroversial, but for some reason morality is a different beast. We struggle against the prospect that the subjective experience of the feelings and intuitions which have informed our conception of morality might be wholly subjective – it’s uncomfortable to suppose that there isn’t an objective reality against which we can hold others accountable and point to and say “No! You’re wrong!” How do we account for this relatively unique property of the moral experience?

 The social theory of moral origins

I have been hesitant to adopt the standard naturalist explanation for the origin of morality as an evolutionary product of our social heritage. Regardless, I have since come to accept that the evolutionary development of a moral faculty driven by social selection pressures is quite plausible. In the following sections I attempt to summarize the key evidences and reasoning behind this conclusion.

Prosociality in non-human primates

If morality is an evolutionary product then there should be traces of it in other species and, in fact, morally relevant sociality is a characteristic of our closest evolutionary relatives (and beyond). This is perhaps best described by just about anything that Frans de Waal has published or, more immediately, his TED talk (below) offers a quick and accessible overview:

Social factors strongly influence our morality

If a social heritage was a key element in the development of our moral intuitions then we would expect to see that social forces have a continued impact on the expression of that morality. This appears to be the case:

  1. surveillanceSocial Awareness: A multitude of studies have demonstrated that even subtle awareness of “watchers” impacts our moral behavior. This may reflect a biological predisposition, but when we allow that our moral sense is in part a development that arises through our life experience, the social dimension of that development also corresponds nicely with this data point.
  2. Social Compliance: Setting aside survival instincts, ‘peer pressure’ is perhaps the most capable mechanism for getting us to act in opposition to our moral sense. The Milgram Experiment, the Stanford Prison Experiment, Nazi Germany and, more recently, Derren Brown’s “Push” program serve as some of the more extreme negative examples. However, this applies equally in reverse, where our tendency to realize an arduous moral good is substantially bolstered by encouragement from peers and anticipation of “other-praising” emotions.
  3. Social Feedback in Moral Development: From a developmental perspective, feedback about character and a disapproving response (a social consequence) is more influential on the formation of our moral sense than is feedback about the moral status of the action itself and a punishing response (a physical consequence).
  4. Social Comprehension: Our moral intuitions tend to calibrate moral culpability in accordance with the moral agent’s capacities and intentions. This feature depends on an interpersonal judgment built on a theory of mind, such as would be inherent in a socially developed morality where other agents inform that development.

In the end, it is clear that the social environment is a primary factor in our moral behavior even when the social consequences of our behavior lie well beyond our perception. This is consistent with the theory that social pressures have guided the development of our moral sense.

The rider and the elephant

elephant_and_riderThe long-standing traditions of moral philosophy and ethics infer that moral judgment is primarily a rational endeavor, but this appears to be a flawed conclusion. Jonathan Haidt has famously compared our moral sense to a rider on an elephant – the rider being our reasoning process and elephant being our emotionally driven intuitions. There is an extensive body of constantly growing literature on this topic, so for a deeper dive on the role of emotion in morality I will simply refer to the writings of Joshua Greene and Jesse Prinz in addition to those of Haidt.

Regardless, the proposition that our moral sense is predominantly emotional only lends support to the social theory of moral origins when we consider empathy and the explanations on offer for the causal link between morality and emotions. Claus Lamm is one of the more prolific researchers of empathy and is a cautious voice at a time when many are hailing mirror neurons and empathy as the underpinnings of our moral intuitions. Despite this caution he affirms that “there is compelling evidence that similar neural structures are activated when empathizing with someone and when directly experiencing the emotion one is empathizing with” (here) and that “There is some support for the above-mentioned role of empathy in morality, although the direct link between empathy and morality remains rather unclear and requires further investigation” (here).

I hope to heed Lamm’s concerns but I also cannot help but step back to view the big picture and see a tidy set of links wherein our moral intuitions are largely dictated by an emotional elephant whose course can be directed by the neurological capacity to take on the perspective of others – a definitively social faculty. The cohesive picture this paints is compelling and when one considers the implications for moral origins, the social theory seems a natural fit.

Moral agreement

bonobo_hugThe last piece of evidence I wish to present for the social theory of moral origins is the very concern which instigated this discussion – the apparently innate drive toward moral agreement. The desire to hold others and ourselves accountable to a particular moral standard has led many to conclude that morality itself is objective (in fact, this is the only non-pragmatic reason I am aware of for the claim of objectivity) but this phenomenon is also explained if our moral sense was developed through social pressures. To say that selection occurred through social pressures is to imply that there is a social dynamic to the evolutionary pathway. This, in turn, requires that there be some sort of reproductive advantage to the selected pro-social tendencies. However, a lone altruist among a band of free-riders is unlikely to realize any advantage. The advantages which arise from prosocial behavior are then also dependent on reciprocity and cooperation. This means that the development of prosocial behavior is most readily accomplished in coordination with the development of proclivities which favor agreement and reject disagreement with respect to those behaviors. The end result is not only a tendency toward prosocial behavior, but a tendency toward favoring agreement on those behaviors.

Some will object here and suggest that our intuitions regarding the objectivity of morality are more like the intuitions we have regarding the veracity of a proposition (e.g., I am sitting on a chair) than they are like a drive toward agreement with others. I’m not sure this is a proper assessment, but I do agree that on the spectrum of intuitions about an entity’s objectivity, our moral intuitions are generally weighted closer toward the ‘objective’ end compared to more broadly subjective claims like beauty, ice cream flavors, etc… This is perhaps most evident in the language we tend to employ in moral discourse, where objectivity is often inferred (though not always – and this inference is certainly also frequently employed in other domains that are generally regarded to be subjective). That said, I’ll offer two thoughts in response:

  1. As noted above, morality is deeply entangled with emotion. The majority of other subjectively informed claims do not carry the same emotional weight, and this is a significant component of the perceived difference and the drive toward absolutes. That is, the strength of the underlying emotions compels us toward an unwavering perspective. There may even be some degree of a subconscious post-hoc rationalization informing an intuition of moral objectivity. The emotional elephant leads the way and the rider can only make sense of the world by rationalizing the course it’s taking as if that is simply reflecting the objective facts about the world. Neuropsychology is replete with examples of how our cognition engages in this kind of post-hoc rationalization and confabulation.
  2. Though speculative, it is not unreasonable to suggest that the evolution of our moral sense may have incorporated the same faculties which bear on our sense of objective veracity if this improves the effectiveness of morality as a motivating factor. Despite the protests of anti-realists, the data does seem to indicate that moral realism is more conducive to moral compliance than is anti-realism (see one, two, three). This makes intuitive sense – if we think that our moral judgments do not have any subjective wiggle room and we can thus be held objectively accountable to those judgments, then we are more motivated to align our behavior with those judgments. So if our moral sense evolved to incorporate some of the same cognitive machinery that helps us judge the veracity of non-moral propositions then the moral sense would be more effective in eliciting the advantage of moral behavior. The net result would be the subjective perception, to some degree, that our moral judgments are in fact objective. Subjective preferences like beauty wouldn’t carry the same selective advantage and so wouldn’t bear the same character in this regard.
Social origins objection #1: Widespread non-social moral intuitions

ralphiesoapSo what about those pervasive moral claims which are devoid of social impact? For example, why have so many cultures moralized purity and why has disgust been shown to influence our moral judgments? How does the social theory of moral origins explain this?

The first point to make on this topic is to note that whereas some moral claims are devoid of a direct social impact, they are typically not insulated from social feedback. In particular, the anticipation of shame is a significant factor in motivating against non-social behaviors which have been moralized.

Second, there may very well be an indirect social impact. In the case where purity or disgust is linked to the non-social moralized behavior we can note that an inadequate avoidance of pathogens is not only detrimental to the individual but also to that person’s social circle. The germ theory of disease converts a seemingly non-social disgust instinct into a socially relevant behavior, such that social judgment that accompanies moralization may in fact be efficacious.

Lastly, if our moral sense is largely an adaptive product of evolution then the evolutionary path is predicated on the behavior which corresponds with our moral sense (because the feelings themselves offer no selective advantage apart from behavior). Evolution favors efficiency, so it is likely that the neurological systems which serve to guide our behavior in general (through the feelings which motivate and inhibit) are also involved in our moral sense, such that there is some level of commonality in our interoception of the morally relevant motivations and the motivations which influence other aspects of our well-being. This would imply that there isn’t a ‘moral’ category that cleanly distinguishes moral interoception from other interoception. So even if the majority of the intuitions that we have categorized as ‘moral’ carry a social relation, it is reasonable that other, non-social intuitions may seem to fit that category as well.

Social origins objection #2: Culturally constructed morality

Many anthropologists have argued that morality is memetic, not genetic. That is, they suggest that the moral sense is learned and acquired from one’s environment – specifically, one’s cultural influences. I think there’s some truth to this perspective, but I don’t see that it is mutually exclusive with an evolutionary explanation. It seems quite evident that cultural influences serve to inform our moral intuitions but this alone does not explain the aforementioned ‘moral referent’, that distinct component of our interoception. I do not doubt that one’s moral compass is informed by their environment but it’s the compass itself that is primarily of interest here, and culture does not explain it’s existence in the first place.

This is an important concept when it comes to the discussion of moral progress. If morality is defined to be nothing more than a cultural construction then the realist is correct to suggest that there is no such thing as progress. However, if there is a biological basis for the moral sense then progress can be assessed relative to that faculty. Even if there is variability across persons, there is still a common origin that fosters some level of agreement at a fundamental level. Here anthropology re-enters the picture to support the notion of an innate moral nature, as elucidated in the work of Donald Brown and Richard Shweder. This is not to suppose that we can necessarily determine right and wrong answers to individual moral claims by reference to that nature alone, but rather to say that there is a general bent which our species shares.

What is a moral claim?

This was the question I asked long ago and hoped to also answer here. In case the preceding discussion has not made it clear, I am arguing that morality is the concept which refers to a particular set of feelings and intuitions that arise as a result of predispositions which developed in our species through social pressures and are shaped and influenced by our development, experiences and reasoning. As such, a moral claim is simply a claim which implicitly or explicitly refers to those feelings and intuitions (or their absence) as if they were properties of an action, person, object or event. This perspective entails a particular moral ontology, namely …

Moral relativism

So it seems that in adopting this view I have officially joined the moral relativist camp. I am quite comfortable with the epistemology and ontology this entails (as outlined above) but these are not informing my conclusion in isolation. Other considerations include:

  1. Dependence on biology:  Though I have already touched on this to some degree, there is much more that could be said. Neuroscience has increasingly demonstrated how variations in our neurology bear on our morally relevant judgements and behavior, as most famously illustrated by the classic cases of Phineas Gage and Charles Whitman (also see Patricia Churchland’s ‘Braintrust’ and, more briefly, David Eagleman’s article in the Atlantic for overviews). While this state of affairs is not logically inconsistent with moral realism, it is more parsimonious with a relativistic ontology.
  2. Moral diversity:  In accordance with the biological dependence noted above, we observe that these variations manifest themselves in widespread moral disagreement. Though it is true that there are many claims where moral agreement abounds, and even some fundamentals that are nearly universal, it is also the case that moral disagreement is more rampant than is found in objectively arbitrated claims. That is, we are more likely to disagree about a moral claim than to disagree about a claim that is based on empirical observations. As before, though this condition is not incompatible with moral realism, it highlights a divergence from the ontologies we posit for most of the entities that we identify as objective and so it is in that sense unexpected. Conversely, such diversity is entirely expected under a relativistic framework.
The implications

Epistemology and ontology aside, relativistic normative ethics is admittedly troubling. Not because I am forced to subscribe to Dostoyevsky’s “all things are permitted” – the shallow characterization of relativism which completely abandons both normative ethics and moral discourse and is often parroted by theistic apologists. No, the trouble is that normative ethics are inherently social and even when we employ frameworks which seek to satisfy our moral intuitions about fairness and reciprocity, such as social contract theory, we are unable to realize the ideal. The application of a normative ethic at the social level will require some level of subjugation wherever there is genuine moral disagreement. Perhaps this is simply an inescapable tension which is intrinsic to our moral sense; a consequence of the unavoidable competition between the benefits of both freedom and cooperation. Just as the realists must concede the inability to objectively arbitrate the moral truths to which they subscribe, perhaps the relativist must concede that the implementation of normative ethics cannot escape the morally distasteful act of imposition. Thrasymachus made a similar observation 2500 years ago and as far as I can tell we’re no closer to a solution. It’s worth continued discussion, but I have grown increasingly skeptical that it will ever be resolved.

Moral relativism also does not mean that we surrender our ambitions of moral progress. There is a human nature and even pervasive moral intuitions are sometimes inconsistent, or in conflict with our nature, or uninformed or misinformed by errant beliefs. Moral discourse and experience can elicit change so that our moral judgments are more accurately aligned with reality and with our inherent nature. Relativism does not mean that we accept all moral claims as equally true. It does not entail pacifism, complacency or anarchy. It does not ask us to ignore our sense of indignation and stand idly by. No, none of these strawmen are true if you’re willing to scrutinize your moral judgments. Can a moral relativist tell somebody else that their behavior is wrong? Yes, but be ready to expose the inconsistencies and faults in their reasoning. Can a moral relativist promote or discourage social policy? Yes, but be ready to use evidence to justify your position, preferably with reference to fulfillment of human nature. Can a moral relativist fight back or intervene when they perceive wrong? Yes, of course. I’m not sure I understand why I even feel the need to answer that question but the rhetoric around this issue suggests that I do.

The big objections

hitlerWhich leads to the big question. It was going to happen eventually, so I might as well put Godwin’s law into effect now: “Relativism, huh? So the Nazis weren’t wrong?” Under relativism I am able to say that the Nazis were wrong according to my intuitions and those of everybody I know, but I’m not making an absolute claim. Notice that the framing of the objection begs the question for moral realism, so it’s a bit of a trap that tries to force a response within the bounds of that assumption, pushing one to grapple with the intuition toward objective morality that was the focus of the prior discussion. That said, it seems to me that it’s also very reasonable to argue against the legitimacy of the Nazi program on the grounds of errant beliefs and an inconsistency with the moral nature of those who carried out the program. Furthermore, as noted above, there is nothing about relativism which entails inaction or ambivalence toward those with whom we disagree.

“and there’s nothing wrong with torturing babies for fun?” Again, I am perfectly able to say that this is wrong according to my intuitions and those of everybody I know, but I’m not making an absolute claim. However, this is a bit more difficult because there isn’t any reason in this case to also object on the grounds of errant beliefs or conflicts in human nature. If an individual were to be biologically disposed so that they did not find this behavior morally abhorrent then I have nothing but disagreement to offer (though I would argue that in a practical sense, the realist is in the same position). As before, this does not entail inaction or ambivalence.

The last word

In the end, moral relativism is neither pacifism nor a blank check. It requires introspection, reasoning, evidence and discourse. We sometimes act in ways which are in opposition to our true values and intentions; we experience regret. Relativism suggests that you take a hard look and try to understand those values and intentions – to consider whether they actually align with your nature and to examine how they are best achieved – and then to direct your life accordingly. You will still mess up, but at least you are trying and that diligence can eventually shift the underlying feelings and intuitions into closer alignment with reason and, hopefully, reality.

“Ha! Caught you. That’s self-defeating! You can’t say that moral relativism requires scrutiny of our moral judgments! That’s an absolute moral claim!”

I have indeed made a normative assumption, but that assumption was not moral. It was an assumption about the reliability of cause and effect. So allow me to rephrase: moral relativism is most rational and most able to accurately satisfy our morally relevant desires when coupled with introspection, reasoning, evidence and discourse.

I embarked on this truth-seeking pilgrimage four years ago and in doing so devoted myself to following the evidence wherever it leads. Accordingly, I have refrained from aligning with any particular moral theory for most of that time. It is an incredibly complex, confounding, divisive and emotionally draining topic. Evidence is difficult to gather and interpretations abound. So while I have finally taken the step of adopting a moral ontology, it is perhaps more tentative and provisional than any other position that I have staked, even as I recognize that this hesitancy is almost entirely emotionally motivated. Regardless, if you disagree with the conclusion then you are welcome to try and change my mind. That’s why I’m here.

Entropy, causation and prophetic typology

For some time I have been slowly working through a gargantuan post that aims to review and comment on each and every one of the 355 Prophecies Fulfilled by Jesus (and there’s still a long way to go). In the course of that process I’ve had to put some thought into the concept of typology, which claims that some earlier entity or event (E0) is a type, or prefigure, of a later entity or event (E0+t). With regard to prophecy, the idea is that E0 is directed toward E0+t in a teleological sense – that is, E0 existed for the purpose of serving as a pointer to E0+t. As I see it, this is a type of retrocausality, in that we could say that we have E0 because of E0+t. My understanding is that this was commonly accepted as a valid perspective in the ancient world, which stands in contrast to a more modern, “scientific” conception of causality that operates only according to the arrow of time.

S = k log WHowever, I have also been reading Sean Carroll’s ‘From Eternity to Here’ which, if I’m understanding correctly, suggests that the temporal causality we see (that earlier events ’cause’ later events) is merely a macroscopic artifact of the universe having started in a low entropy condition. At root, all physical laws are reversible, such that there isn’t really a direction of cause and effect – there’s just a universal trend from lower to higher entropy because high entropy states are simply more probable than low entropy states.

So now I find myself intuitively balking at the nonsense of the retrocausality suggested by typological claims while simultaneously pondering this entropic perspective on time and the reversibility of physical laws, and subsequently wondering whether E0+t really can be a valid part of the explanation for E0. I’m not sure I’ve really wrapped my head around this, so I’m hoping for some additional insight from any readers who feel like they might have something to offer. In short, does a properly scientific perspective on time and causality lend credence to notions of retrocausality, such as we find in claims of prophetic typology?

Note that I am not suggesting that prophetic typology claims would thus become the best explanation for an identified relationship between E0 and E0+t as a result of this perspective. We can still identify the best (i.e., more probable) explanations according to the probabilistic description of entropy, which we perceive as a causal direction from past to future in accordance with physical laws. The question is only whether those prophetic claims are more compatible with a proper scientific perspective on causality versus the classical view of an inviolable temporal order from cause to effect.

Counterfactual arguments against biological design as revelation

The design of a watchThe argument from design is perhaps the most intuitive and immediately accessible argument for the existence of God and can be analyzed from a myriad of different perspectives. We are surrounded by astounding complexity and see purpose in nearly everything. William Paley was reasonable to suppose that the watch infers a designer and the design proponents are reasonable to say that life is brimming with the appearance of design. But fifty years after Paley’s death, Charles Darwin published “On the Origin of the Species” and the design explanation suddenly had a legitimate competitor.

When I consider the arguments for these two options – design and chance – I find myself repeatedly drawn to a niggling question: if design is correct, why is life designed in a way that is plausibly explained without design? That is, if the designer wanted us to infer design then it would seem that he could have done better. Upon making this assertion, the apologist in my head immediately responds with an emphatic “Like how?”; inferring that I am posing an alternative that may not be viable. In this post my aim is to explore that very question through a few counterfactual conditionals.

Counterfactual #1: Reproduction

The first counterfactual condition I would like to consider goes something like this:

“If God really wanted to reveal himself through the genetic design of living organisms then the mode of perpetuating life would defy a purely naturalistic evolutionary paradigm.”

Those familiar with the intelligent design movement will recognize that this is similar to what those proponents often claim. The arguments are rife with assertions of irreducible complexity and astronomical improbabilities for the spontaneous assemblage of molecules while simultaneously disparaging any plausible explanation for the origin of those structures as ad-hoc speculation. Though it may be true that it is extremely difficult to verify and obtain evidence for those explanations, this does not negate the fact that those explanations are plausible and consistent with the regular mechanisms of nature. Perhaps with a little imagination we can identify a way in which the designer might have made it more clear that life was not a purely natural phenomenon…

Let the earth bring forth living creatures NOT after their kind…

We are really only familiar with one kind of life: the kind where amino acids combine in various ways and facilitate production of new life which is nearly equivalent to the parent(s). We see this in bacteria, flowers, frogs and people. We call it reproduction because the output is essentially a new instance of the producer(s). The variation from parent to child is relatively insignificant compared to the full volume of information embedded in the process. For our purposes here, we can essentially say that A => A => A => …, or, in other words, life form A only begets life form A and nearly all genetic information is carried forward.

Now consider an alternative to this. Collections of molecules regularly interact with other molecules in the environment to produce new molecular structures. In fact, this is exactly what is happening when our DNA guides the production of proteins. Those proteins are wholly different from DNA and go on to perform many functions and interact with other molecules in ways which leads to other changes in chemical structures. These reactions may carry on for some time, maybe indefinitely, without ever going through the same cycle of inputs and outputs. This is like reproduction, but with the key difference that the product has a markedly different chemical structure than the producer. I propose that this scenario hints at a possible second mode of life (unified material which is capable of producing new life) which looks something like:

  • sloth_bear_babyA => B => A => …, or
  • A => B => C => D => A => …, or
  • A => B => … => Z => A => ….

The set of possible Rube-Goldberg like chains of production is enormous, so long as there is a recursive structure that allows us to avoid an infinite regress and constrain life as the set of outputs within the cycle. Otherwise – without recursion – every possible reorganization of matter would be “life” in some weak sense.

What are the odds that life, under the guidance of purely natural processes, would arise to operate under this second mode instead of the first? This question is probably answerable even if I’m not going to try and expend the resources to calculate it here. Regardless, it’s clear that the probability of this occurring by chance is significantly less than it is for the type of genetic duplication we see in the world now. So, at the very least, we have identified a possible mode of life which would have been a stronger indicator of design than is inferred by the current paradigm. Perhaps the current mode of life was intelligently designed, but if so, then it seems that intelligence might not have wanted us to know.

Counterfactual #2: Intelligence

Inspired by a recent post by Nate at ‘Finding Truth’, the next counterfactual condition I would like to propose is:

“If God really wanted to reveal himself by blessing us with advanced cognitive abilities then our cognitive limitations would not be compatible with the naturalistic evolutionary paradigm.”

Nate’s post was spurred by a theist’s claim that our advanced cognitive abilities, such as “philosophical insight, scientific acumen, or mathematical skills” defy natural explanation. I responded by suggesting that the converse seems more accurate.

thinking_fast_and_slowWe have become increasingly aware of our cognitive limitations as we have applied scientific methods to observation of human behavior, revealing a pervasive susceptibility to error through inherent biases and external influences (see Kahneman’s ‘Thinking Fast and Slow’ for a nice introduction). In fact, the scientific endeavor itself is a process for minimizing those errors. I outlined my own criteria for discernment (Part 1, Part 2) a few years ago when I realized that it was an integral and necessary part of any truth-seeking journey.

But this goes beyond errors in judgment. A substantial body of research is showing just how fragile and malleable our long-term memories actually are. The memories of our past are largely reconstructed. Even our short-term memory is limited to about 7 items. Then there’s also the consideration of those alleged “mathematical skills”. Hasn’t the advent of computers shown us just how slow and error prone our math skills actually are compared to what is possible?

There’s really no telling where we lie on the continuum of intelligence. Yes, relative to other lifeforms on earth we seem to be at the top, but as technological advances continue to give us glimpses into the kind of reliability which may actually be possible you can’t help but feel like we aren’t so close to the pinnacle after all. So, if a designer is trying to reveal himself through the gift of advanced intelligence, then why do these findings make it so easy to imagine a better human who isn’t dependent on tools and processes to mitigate against cognitive error and limitations? The holy books which purport to capture knowledge of supernatural origin also seem to be consistent with a natural origin and betray the humanity of their authors. Where is the evidence of a supernaturally gifted intelligence? It seems more likely that we’re just doing the best we can with the empirically grounded capacities which have aided our survival over the millenia and that we owe nearly all of our advanced knowledge to the cumulative efforts of past generations who have worked hard to pass on their knowledge of “what works” so that we don’t have to rediscover everything.

Counterfactual #3: Natural Moral Consequences

When I saw the most recent post at 500 Questions about God & Christianity I couldn’t resist including it here. The post asks “Why doesn’t sin carry natural consequences?“, which he translates into a counterfactual near the end of the post when he says “If God is truly the creator, and the commands in the Bible are his (and not man’s), then we might expect to see the creator enforcing his rules through his creation, but we don’t (suggesting the laws laid out in the Bible were reasoned by men, and not God).” Or, to put it in the context of questioning biological design as revelation, “If God valued the revelation of moral truth (and thus his moral nature) more than our physical comfort then he would have designed us to discover moral truths in ways that are more efficacious than the way that pain teaches us to avoid physical harm”. Moral disagreement is rampant, yet we all pretty much agree that it’s painful to touch things that are hot or sharp.

If you haven’t already, I highly recommend checking out the 65 other questions. The whole blog is pretty much one giant counterfactual argument.

O man, who art thou that repliest against God?

Jars of ClayShall the thing formed say to him that formed it, Why hast thou made me thus?
– Romans 9:20 (KJV)

At this point you may wish to accuse me of naive arrogance in supposing that I can deduce how God should behave. You are right, but I ask that you hear me out. Certainly, if God exists, I am in no position to tell him how he should act, but this says nothing of how we are to interpret the evidence for his existence. If I wake on Christmas morning to find a set of binoculars under the tree made out of two toilet paper tubes, scotch tape and string, it is entirely reasonable to conclude that it was produced by my children and not by Nikon or Bushnell. Likewise, if God wanted us to infer his presence from the life found in his creation, then it seems he could have done better. If God directed acts of special creation, or the course of evolution, then it would appear that he chose to leave a signature which is indecipherable from what we might get from a lawful yet unguided process. Does this sound like the behavior of somebody who wants us to know him?

This observation offers no definitive conclusions regarding the question of whether a designer lies behind the structure of life and counterfactual arguments are inherently weak due to their speculative nature. What it does do, however, is offer an argument which generally favors either (a) the absence of a designer, (b) a designer who doesn’t really want us to find him through inference to design, or (c) a designer who is incapable of generating the most compelling inference to design. None of these fit with the classical theistic definition of God:

What is a moral claim?

ScalesI thought I had something like an epiphany several weeks ago and had finally identified a theory of ethics that I could say was, from my perspective, “most probably true”. I started writing and had drafted outlines for a 9-part series. I wrote, and read, and thought … and then I stopped. I hit a wall. The theory, like every other moral theory ever, was incomplete. There were unexplained assumptions and unanswered questions.

The pseudo-epiphany began with a realization that I had misunderstood the core definition of moral realism, which is

Moral Realism:  Moral claims can be true or false and some are true.
(extracted from the Stanford Encyclopedia of Philosophy article)

Despite my interest and reading on the nature of ethics these last couple years, my prior conception of moral realism did not align with the definition above. Through numerous sources and interactions I had been led to define moral realism as requiring ontological independence – that morality, in a sense, exists on its own in some way (though I should note that the SEP article does add the disclaimer that “some accounts of moral realism see it as involving additional commitments, say to the independence of the moral facts from human thought and practice, or to those facts being objective in some specified way”). I guess that’s what happens when most of your education on ethics comes from sources in the God debate. Regardless, the definition given above is much less restrictive in its application than I had previously conceived and as I pondered this I found that it opened the door to new explanations for our intuitions regarding the truthfulness of moral claims, though I eventually began to doubt that I was really heading toward any kind of solution. Even so, I’m not yet willing to admit defeat, so I’m calling in reinforcements (yeah, that’s you). I have several “open questions” and I would like to solicit your input to help me clarify some things. My first request is for answers to the question “What is a moral claim?”, but before you answer, let me give you something to think about.

First, note that the definition of moral realism assumes that we know what a “moral claim” is and, the more I think about it, the more I question whether we can define “moral claim” without presupposing moral realism. To help illustrate this, I’d like to run through a couple examples. Consider the following two sentences:

  1. It is wrong to skin a cat.
  2. It is wrong to turn a screw left to tighten it.

We generally agree that #1 is a moral claim and that #2 is not. Now consider the following:

  1. It is wrong to turn a screw left to tighten it on a Wednesday.

Now the turning of a screw has become a moral claim. What changed? What is it that makes #1 and #3 moral claims, but not #2? As best I can tell the difference is in the referent of ‘wrong’. Claim #2 is referring to a goal – the outcome of tightening the screw, so ‘wrong’ in this context means that the goal will not be met. What is the referent in #1 and #3? Well, the referent seems to be morality itself – some standard of good and bad that isn’t really definable in any other terms without presupposing the existence of morality itself. That does not, however, mean that morality is thus necessarily independent of everything else. It simply means that our faculties are not equipped to define it by reference to something else. As far as I can tell, this leaves us with some form of moral realism – and it’s worth noting that under the definition given above, relativism is a form of realism. It is just a limitation on the scope of the moral truth.

As far as I can tell, this throws various forms of anti-realism out the window. There may be gray areas where it’s hard to tell whether something is or is not a moral claim, but at the extremes even an anti-realist can identify a moral claim from other types of claims. There must be something that they’re drawing upon to do that. That “something” may reduce to emotions, or some neurochemical state, but that’s still something. It’s real.

What do you think? Am I right about this? Does our ability to distinguish moral claims from other claims require moral realism?

PS: If you’re interested, this theory that I’ve put on ice is somewhere in the vicinity of contractualism with a contract that is based on negotiation between the core value judgements of all parties, rather than rational agreement, where by “core value judgements” I mean something like what we see in Jonathan Haidt’s moral foundations.

Consciousness and the Brain

Last month a commenter suggested that “I would be interested to see you research and post on ‘How science addresses the subjective, in relation to consciousness and freewill'”, to which I responded that I might write up a summary of the ways this is addressed in the book I was reading, Stanislas Dehaene’s “Consciousness and the Brain: Deciphering How the Brain Codes Our Thoughts”. Furthermore, the comment offered a particular direction to consider, namely that science can “collate and analyse subjective reports and hope something comes out of this – e.g. by correlating objective measurement with the subjective reports. … The problem with this is that these results are generally not accorded the same scientific status.” Dehaene actually spills a considerable amount of ink in the opening chapters addressing this concern. For example:

Consciousness and the Brain“This research strategy was simple enough, yet it relied on a controversial step, one that I personally view as the third key ingredient to the new science of consciousness: taking subjective reports seriously. … The participant’s introspection was crucial: it defined the very phenomenon that we aimed to study.” (pg 11)

“The correct perspective is to think of subjective reports as raw data. A person who claims to have had an out-of-body experience genuinely feels dragged to the ceiling, and we will have no science of consciousness unless we seriously address why such feelings occur. In fact, the new science of consciousness makes an enormous use of purely subjective phenomena, such as visual illusions, misperceived pictures, psychiatric delusions, and other figments of the imagination. Only these events allow us to distinguish objective physical stimulation from subjective perception, and therefore to search for brain correlates of the latter rather than the former.” (pg 12)

“All this evidence points to an important conclusion, the third key ingredient in our budding science of consciousness: subjective reports can and should be trusted. … introspection is a respectable source of information. Not only does it provide valuable data, which can often be confirmed objectively, by behavioral or brain-imaging measures, it also defines the very essence of what a science of consciousness is about.” (pg 42)

The Recipe

Those quotes refer to three key ingredients which go beyond the objective data about brain activity that we can gather through fMRI, EEG and the like. Dehaene identifies these ingredients as conscious access, manipulation of conscious perception and, as noted, careful recording of introspective reports. He then goes on to further define each of these.

Conscious access is defined as the awareness of specific information – it’s the foundational definition of consciousness that underpins more elaborate attributions, like self-awareness. As is elucidated in the book, our brains actually consume massive amounts of perceptual data. Much of what is received by our senses and processed in our brain eludes our conscious awareness. Conscious access is that sliver of data which enters our stream of thought from amongst the mountain of perceptions which bombard us from without and arise from within.

Our conscious access is reportable. As I type this, you are receiving a report of my conscious access. We cannot report on that which we are unaware of, so it is by definition that reports are only informative with regard to the content of our conscious access. Experiments can build upon this by asking participants to focus on a particular element of their perceptual space that has been carefully crafted by the experimenters. This manipulation of conscious perception is the experimental variable that allows the researchers to segregate the data into that which correlates with consciousness and that which does not. Dehaene outlines several primary manipulations – binocular rivalry, attentional blink, subliminal stimuli – and references several others throughout the course of the book. Each of these present an opportunity to separate conscious processing from unconscious processing and so look for the signatures of consciousness.

Dehaene then goes on to highlight the massive amount of work that our brains are doing subconsciously and how this surreptitiously influences our conscious access. Research in this domain paints a picture of the inverse side of consciousness and offered a baseline against which consciousness can be compared. After taking a side trip into discussions about the viability of the evolutionary origins of consciousness as a tool for organizing and prioritizing the competing interests in our subconscious processes, we are introduced to the findings that this recipe has thus far wrought.

Finding Consciousness

The toolkit described above has been extensively deployed in the lab and the cumulative results led Dehaene to identify four reliable signatures of consciousness. They are:

dehaene_fig16

[1] “Although a subliminal stimulus can propagate deeply into the cortex, this brain activity is strongly amplified when the threshold for awareness is crossed. It then invades many additional regions, leading to a sudden ignition of parietal and prefrontal circuits” (Fig 16, pg 119)

(2) "In the EEG, conscious access appears as a late slow wave called the P3 wave. This event emerges as late as one-third of a second after the stimulus: our consciousness lags behind the external world."

[2] “In the EEG, conscious access appears as a late slow wave called the P3 wave. … For conscious words only, the wave of activity is amplified and flows into the prefrontal cortex and many other associative regions, then back to visual areas. This global ignition causes a large positive voltage on the top of the head – the P3 wave.” (Fig 18, pg 123)

dehaene_fig20

[3] “A long burst of high-frequency activity accompanies the conscious perception of a flashed picture … When viewers failed to see the picture, only a brief burst of high-frequency activity traversed the ventral visual cortex. … Conscious perception was characterized by a lasting burst of high-frequency electrical activity, which indicates a strong activation of local neuronal circuits.” (Fig 20, pg 136)

dehaene_fig21

[4] “The synchronization of many distant brain regions [form] a global web … during conscious word perception, causal relations show a massive bidirectional increase between distant cortical regions, particularly with the frontal lobe. Only a modest and local synchronization occurs when the participants fail to perceive the face or word.” (Fig 21, pg 138)

The common attribute which ties these signatures together is that they all represent prolific activity across large areas of the brain. In contrast to Descartes’ pineal soul-suite, the evidence points to consciousness as a phenomenon that is spread throughout the brain when a massive avalanche of distributed activity is launched. This excitation is what Dehaene calls “global ignition”. After having presented all of the correlative data Dehaene anticipates a common objection – correlation does not equal causation – and so he offers evidences to support the proposal that brain activity is more than just a side-effect of the ghost in the machine and that there are reasons to believe we are glimpsing consciousness itself.

“Let us play devil’s advocate again … Might [global ignition] bear no specific relation to the details of our conscious thoughts? Might it just be a surge of global excitation, unrelated to the actual contents of subjective experience? … Calling such a brain event the medium of consciousness would be like confusing the thump of the Sunday newspaper on our doorstep with the actual text that conveys the news.” (pg 142-143)

The first stop for the counter against this objection comes at the Centre for Systems Neuroscience at the University of Leicester in the UK, where Rodrigo Quian Quiroga enjoys probing individual neurons and finding ways to incorporate pop culture icons into his experiments. He has spent the last decade examining the relationship between conscious access and discrete patterns of neural firing at the level of individual neurons. The short story is that through a novel technique pioneered by Itzhak Fried, we have been able to take advantage of the surgeries performed on epilepsy patients to implant fine electrodes that record from individual neurons. When these are monitored during experiments there are very specific relationships found between perceptual and recollected concepts and individual neurons. Those experiments have not only identified a link between concepts and individual neurons, but the same tools used to investigate consciousness have been utilized to show that some neurons are only linked to conscious perception of stimulus – in effect, the neuron can be said to be a part of a conscious thought. These findings have been documented across many publications, but a few of the key overview papers are “Concept cells: The building blocks of declarative memory functions” and “Brain Cells for Grandmother“. Furthermore, similar findings led to the awarding of the 2014 Nobel Prize in Physiology or Medicine for the discovery of place cells; individual neurons which correlate with our location in space. These were first discovered in rats and then subsequently also identified in humans. The extrapolations we can draw from the discovery of an association between individual cells and conscious perception are potentially monumental. In particular, it does not seem inconceivable that perhaps some day we may be able to translate the philosopher’s qualia as a pattern in the brain.

Transcranial magnetic stimulation in 1911 (C.E. Magnusson and H.C. Stevens)

While fascinating, the added specificity of the single neuron experiments has not yet established causation. It could be that those individual neurons are simply assigned dedicated roles as the bridge between body and particular concepts of the mind. Perhaps in those experimental observations we are simply bystanders watching as the train of thought passes by. That is not impossible, but there’s more to examine. The next stop starts with a bit of time travel back to the early 20th century, when several parties began toying with transcranial magnetic stimulation (TMS) and reporting various sensory anomalies in conjunction with the activation of the coils. Vast improvements in the equipment have allowed these experiments to continue today with sharp precision that enables experimenters to focus the stimulus to specific regions of the brain. In doing so, they have been able to trigger domain specific sensory illusion – light when there is none to be found, motion while sitting still and color in a monochrome scene.

Perhaps more significant, however, is not the creation of sensory perception through TMS, but rather the disruption of consciousness itself through the same mechanism. Magnetic pulses targeted toward the long-distance networks that facilitate global ignition have been shown to eradicate a conscious perception that would have otherwise obtained. Even more relevant to the question of the interplay between the subjective and the objective is a study in which the prefrontal lobes were overwhelmed with pulses, leaving an effect which lasted up to 20 minutes. During this time, the subjects were asked to perform simple tasks of judging shapes that were presented to them. Objectively, their accuracy was effectively equivalent to their performance prior to the stimulation. Subjectively, however, they reported significant doubt in their answers. Objectively they were just as capable but their conscious awareness of their judgement had been impaired.

Before closing this section I must acknowledge that for the resolute dualist, we still haven’t fully addressed the objection. Maybe the TMS is acting in the place of our sensory input, stimulating or disrupting those neural mind-bridges in such a way that the mind thinks it is receiving or missing sensory data. OK, then let’s go beyond the content of the book and take a look at some additional research. If we say that the mind is distinct from matter then theoretically our memories are also made of mind stuff. However, starting about 70 years ago with Wilder Penfield experiments have been shown to trigger memory recall through direct electrode stimulation of specific brain regions. Whereas the dualist could argue that this stimulation is no different than the recall we experience when a familiar sight or sound is encountered through sensory input, the distinction becomes apparent when stimulation is used to disrupt conscious memory recall. For example, by acting directly on brain regions associated with verbal memory, electrical stimulation can directly impair recall of names for familiar objects and this phenomenon is often used to locate brain function through the process of cortical stimulation mapping. It is not that the person’s sensory perception of the object is disrupted but rather that their recall of the memory content which associates words with the object has been impaired. I find it difficult to understand how this result fits into a dualist framework.

In total, there is a large body of evidence that the content of our thought-life is causally connected to our neurology. We have opened an objective window onto the world of the subjective and on to consciousness itself. Massive projects are underway and, though we are still far from grasping the means of translation between the subjective and the objective, the future appears to be one in which mind and matter are proven to be one and the same.

The Diving Bell and the Butterfly

Dehaene outlines his theory of consciousness in the fifth chapter but it’s really just a review of the ideas that he has already outlined in the previous chapters. His theory, in short, is that consciousness is roughly equivalent to the concept of “global ignition” introduced above, with the added dimension of feedback loops containing the information which persists to define our subjective experience. This is what he calls the “global neuronal workspace” theory. Information is shared throughout the brain as an evolutionary adaptation which allows us to utilize it in various ways and prioritize our attention. Within this discussion several neural computer simulations are presented which demonstrate a similar type of threshold ignition and feedback, which is central to the theory, even though that particular behavior was not deliberately designed into the model. Then, having built his theory of consciousness upon the key signatures identified above, Dehaene sets out to find a way to test it. It is one thing to find correlates of consciousness, it is quite another to use that information to build a reliable “consciousness-o-meter”.

Jean-Dominique-Bauby

Jean Dominique Bauby and his secretary

The proving ground for this theory is found in one of the most difficult medical scenarios; that of the vegetative patient. We are introduced to the spectrum of states which manifest in response to a severe insult to the brain: from brain death, to a vegetative state, to minimal consciousness and locked-in syndrome. That last of these occurs when a fully conscious brain is “locked in” to an unresponsive body, as was the case for Jean-Dominique Bauby when he authored The Diving Bell and the Butterfly with just one blinking eye. The difficulty in these cases is that with only the subject’s external, objective behavior available to the clinician, the ability to determine whether there still any internal conscious life and hope for recovery is radically impaired. What’s worse, the manipulative tools which were used to detect the signatures of consciousness in the lab are also taken out of contention due to the inability to rely upon the subject’s ability to focus their sensory perception and report on their conscious access. An alternative technique relies on the observation that we are wired to detect novelty, such that changes in our surroundings trigger a response in the brain. This trigger, however, fires even if the novelty never enters our conscious awareness. That, in turn, means that the novelty itself is not sufficient for establishing the baseline that discriminates between the unconscious response and conscious detection of the change. To get around this the research team devised a clever tool called “global auditory novelty”. Relying upon the fact that the sense of hearing is rarely lost in these brain injuries, the subjects were presented with a pattern of four “beeps” following by a “boop”. The “boop” represents the local novelty which triggers the subconscious alert that something has changed, which may or may not enter our consciousness. Our long-term, or “global” conscious perception, however, is a bit more sophisticated. Once this pattern is repeated enough times the “boop” becomes part of the expected sequence even though it triggers the alert in the brain. This causes the “boop” to eventually slip out of our conscious awareness. So, by repeating the pattern several times and then replacing the local deviant “boop” with a global deviant “beep”, the team was able to induce a situation in which the subconscious alert was silent while the conscious detection of a global novelty was ignited.

What was the result? In the initial trial with eight patients, all three of the minimally conscious patients whose EEG’s lit up with the P3 wave in response to the global novelty later regained consciousness. In a subsequent study with 22 vegetative subjects only two yielded a P3 wave and they both became minimally conscious in the following days. While these initial tests were perfect in that they never yielded a false positive, there were still several false negatives. To address this the group compiled their data and ran a statistical analysis to refine the prediction from the EEG waveforms. This refined calculation, which incorporated the full suite of EEG data and the other signatures beyond just the P3 wave, led to an exciting result. Using a data set of over 200 patient they found that in 33% of the cases where the clinical diagnosis was “vegetative state”, the refined analysis yielded an alternative diagnosis of “minimally conscious”. Of these, a full 50% recovered to a clinically obvious conscious state in the next few months, whereas this false negative rate was otherwise only at 20%. Adding these up, we see that the clinical diagnosis was overly pessimistic for 30% of the patients while the EEG signature diagnosis was overly pessimistic for only 13% of the patients. For families struggling with questions about how to manage the care of their loved one as they cling to life, this objective detection of consciousness through physical measurement of brain activity may be the key to maximizing the realization of their hopes.

The Future

Dehaene spends the last chapter of the book examining the ways in which the science of consciousness will continue its assault on the mystery of the subjective experience. Here we are presented with data to show that the global workspace theory of consciousness tells us that infants are conscious at birth and that several other animals exhibit the signatures of consciousness. He then turns his attention to the philosophical problems of qualia:

“My opinion is that Chalmers swapped the labels: it is the ‘easy’ problem that is hard, while the hard problem just seems hard because it engages ill-defined intuitions. Once our intuition is educated by cognitive neuroscience and computer simulations, Chalmers’s hard problem will evaporate. The hypothetical concept of qualia, pure mental experience detached from any information-processing role, will be viewed as a peculiar idea of the prescientific era, much like vitalism” (pg 262)

and free will:

“Our brain states are clearly not uncaused and do not escape the laws of physics – nothing does. But our decisions are genuinely free whenever they are based on a conscious deliberation that proceeds autonomously … When this occurs we are correctly speaking of a voluntary decision – even if it is, of course, ultimately caused by our genes, our life history, and the value functions they have inscribed in our neuronal circuits.” (pg 264-265)

While I am not yet willing to express a level of confidence on par with Dehaene regarding his conclusions, I am obliged to say that I agree (and I posted similar thoughts on free will in the post which inspired those introductory comments last month). Even so, neuroscience may never be able to deal an incontrovertible death blow to the dualist paradigm. Like Sagan’s infamous garage dwelling dragon, the mind can always be excused from questioning and made into an extra immaterial layer that mirrors the brain even at the level of individual neurons and synapses. At some point, however, it becomes clear that we are just playing games. When that time comes, if it hasn’t already, we need to acknowledge the data for what it is and the implicit conclusion that we are nothing more than our physical body; that our identity – our conscious self – is found in our brain.

A pragmatic approach to free will

PinocchioEarlier this year I engaged in a discussion on doxastic voluntarism where a commenter stated that

“I use freewill to mean we can choose to change the physical sequence of events in our brains. … If we don’t have genuine freewill, then we can’t choose”,

to which I responded with

“Regardless of where one stands on free will, we agree that we engage in something called ‘choosing’. This phenomenon is universal whether we think it is performed by a ghost in the machine or it is just another cog in the chain of prior causes.

This thread of the discussion carried on a little longer without a mutual understanding and eventually ended with me saying that I would try to explain myself in a new post.

So here we are. I currently suspect that we do not have libertarian free will; that is, I doubt that there is an uncaused part of us which controls the act of choosing. This is not a certainty, but I am compelled by the evidence (and the lack of alternative evidence) that this is probably a correct description of reality. So, now that you have received this revelation, you may climb back in bed and curl up in a ball and wait for your death because you are just a cog in a chain of causes. You are no different than the computing device you are currently using. You are a powerless bag of molecules, a meat puppet dangling by the strings of chance. Upon believing that your choices are byproducts of everything else, you could, paradoxically, immediately succumb to a self-defeating fatalism or you could keep reading and take another path. What will you do? Is that even a meaningful question?

This post does not seek to argue whether or not we actually have libertarian free will. The point of this post is to consider the implications for our sense of freedom if we do not possess uncaused agency.

Wait. How do you explain our experience of choice?

Pinocchio_to_lifeGood question. Even though I have no intention here of making the case for an absence of libertarian free will, it is worth considering whether that situation is even possible. I would like to start by reflecting on some observations which are representative of things that we’ve all experienced at one time or another.

The other day the book I was reading included a comment that “…animals don’t seem to want to party, despite what we see in children’s cartoons like Madagascar.” About 30 minutes after reading that – I’m slightly embarrassed to admit – I found myself with the Katy Perry song “Firework” in my head. Upon recognizing this I was surprised, so I stewed on it a bit. This is not a song that I encounter frequently in my listening habits. When I stopped to think about this, a faint scene began to play in my mind. It was an animation of zoo animals performing circus acts. You see, about a week earlier, I spent a couple hours watching Madagascar 3 with my sons. Near the end of the movie, the main characters engage in an elaborate circus performance set to the music of – you guessed it – “Firework”. Unbeknownst to me, the reference to the Madagascar movie in the book I was reading had set in motion a network of activity, drawing on recent experience, that led to the production of a particular song in my head.

When I was a kid my brother would play the “made you flinch” game. It may be a stretch to call it a game, but the rules are basically this: at any time, you can go up to your sibling and act like you’re going to hit them and then stop short. If they react in a defensive way then you have license to actually hit them. Twice. By definition, a flinch is involuntary. After enough bruises you learn to remain vigilant and can suspend your reaction, but eventually you will be caught off-guard again. Control of the flinch is subject to awareness.

As a final example, we’re all well aware that repetition can train us to do things effortlessly and thoughtlessly even though these things required considerable conscious attention during the initial training. This includes actions like reading, riding a bike, driving a car, using a mouse, etc… Even simple math eventually becomes automatic. These well-trained processes seem to lie on the borderlands between the intentional and the unintentional, lying just below the level of consciousness and waffling in and out of our awareness. We sometimes catch ourselves unaware that we had done something, or are doing something.

As these examples show, it is possible for behavior and mental activity to arise outside of our immediate awareness and control. They do not run through the “free will” filter. If we acknowledge that this is possible then it seems reasonable to acknowledge the further possibility that choice itself, our apparent exercise of free will, restraint and deliberation, can also arise through causative factors outside of our awareness. Under this paradigm, we might say that choice is what happens when our brain deals with competing interests. Even choosing to get up and get a drink is in competition with a desire to conserve energy and stay where you are. We have a remarkable feedback system that can recall past experiences and forecast future experiences. These work themselves in to the choice equation and sometimes we can spend considerable time and energy in deliberation as the network keeps pulling up data on both sides of the tug-of-war and reconfiguring itself in response.

The insistence that we make choices independent of causative influence begs the question. It assumes that our identity is fully contained within a singular, unified, independent perspective; in short, a ghost in the machine. Yet, if we ask someone who has flinched whether they chose to flinch then they’re most likely going to say that it wasn’t a choice while at the same time agreeing that they acted. Likewise, we will not deny that it was us who performed automated tasks, even if we weren’t fully aware of what we were doing. So in some cases our action can come from some sort of involuntary aspect of our self. That is, we do not always disassociate our self identity from the actions which were not clearly “under our control”. If we accept that this is a part of who we are and that the line between voluntary and involuntary does not demarcate our identity, then I see no reason why the abolition of libertarian free will should be seen to annihilate the self and render us incapable of choice. Instead, our conception of the “self who chooses” must be revised so that it is consistent with the fact that we already include our involuntary self in our identity. We dispose of the idea that we are a singular, unified and independent soul and find that our identity is multifaceted, distributed and interdependent. Incidentally, a rare group of split-brain patients have offered us a fascinating window into how this works, as do patients who have experienced certain brain injuries (see blindsight, visual agnosia and hemispatial neglect). It appears that this distributed view of the self is the more accurate perspective.

You should believe that you can make choices

pinocchio_donkeyAs demonstrated by the original quote at the top of this post, it is common to see claims that the rejection of libertarian free will is also the rejection of choice. I will address that claim further in the next section, but first I want to briefly review why you should believe that you – this new, complex, multifaceted you – can make choices. When we believe in free will:

  1. We are less likely to harm each other and more likely to help each other (Baumeister 2009).
  2. We are more likely to act fairly and show gratitude (Vohs 2008, MacKenzie 2014; though Zwaan failed to reproduce Vohs).
  3. We show less prejudice against predetermined group membership (Zhao 2014, and accordingly, we show more prejudice against chosen group membership – Brewer 2013).
  4. We are more likely to detect errors and invest in thought (Rigoni 2014, Rigoni 2013, Lynn 2013).
  5. We are less likely to succumb to impulses and more likely to exercise self-control (Rigoni 2012, Alquist 2013, Job 2010).

Given these results, the evidence seems to suggest that we prefer the versions of ourselves who believe in free will. The pragmatist follows by suggesting that the rational thing to do is to believe that we actually possess this freedom.

But I can’t just pretend for the benefits

I completely understand the objection and agree that in the short term we can’t choose our beliefs – but I’m also pretty sure that you don’t have to pretend. Even when you think you can give a reason for your choice we can always just ask why again, and keep asking why until you get to the point of saying “I don’t know”. Eventually you will get there, which means that as far as we can tell from pure introspection, there appears to be something unexplainable going on. This is where we find our “free will”.

It is possible that there actually is no prior cause at the bottom of this search but, as we have seen, it is also possible that the prior causes are simply elusive or inaccessible. If you disagree, please explain to me how this kind of experience would differ from the experience under libertarian free will. I don’t see a difference and, introspectively, we have nothing but our experience to go on. So, if our internal experience regularly lacks a fully formed understanding of causation and if we recognize that we can choose between options, why does it matter whether or not our choice is actually uncaused? Pragmatism takes over when explanations run dry and suggests that instead of looking at causes, we should look at effects. We feel a sense of control and operate with the experience of control and this results in outcomes which accord with our choice. Is this not sufficient?

pinocchio_homeFrom a purely experiential perspective, I make choices. If there is no libertarian free will then I may end up in bed, shut off from the outside world because all prior causes led to that condition. However, it is equally true that all prior causes may lead me to fight off the melancholy and seize the day. We don’t know which is the future path of the causal chain, yet we detect an ability to direct it. The internal experience is the same; our sense of freedom is present no matter what. This is all that matters when it comes to the choices we make. You needn’t sacrifice your freedom on the alter of fatalism. You have a choice.

If you have read this, and you find yourself agreeing with my conclusions, then it is possible that your experiences have now changed you so that you are more inclined to invoke your sense of free will. Ironically, you have just been externally caused to have a greater sense of freedom. Run with it.

Mind and Cosmos

mind_and_cosmosThomas Nagel’s “Mind & Cosmos”, published in 2012, is almost certainly the book that has garnered the most attention over the last couple years in the God debate; and it has thus become required reading for those of us who are immersed in that milieu. My encounters with the book have primarily come through the off-handed endorsements of Christian apologists. It has become a weapon of choice for defense of the theistic worldview. Conversely, the naturalists were quick to call foul. Most famously, Steven Pinker called it “the shoddy reasoning of a once-great thinker.” Deeply critical negative reviews abounded and those who rushed to Nagel’s defense were quick to suggest that he was, in an ironic twist, being treated like a heretic by the clergy of the church of science. With all of this in mind, my goal was to approach this book via the middle road, as someone seeking truth wherever it may be found. There’s no doubt that I am flawed and biased, but I honestly hope that I came to the text with an open mind.

So what is all the fuss about? Perhaps the subtitle of the book says enough: “Why the materialist neo-darwinian conception of nature is almost certainly false.” That’s a pretty bold statement which, when viewed through the lens of the God debate, clearly lands in the theist’s camp. Furthermore, students of apologetics will quickly recognize that the content bears a striking resemblance to some of the key objections to naturalism that have been levied by the likes of C.S. Lewis, Alvin Plantinga and J.P. Moreland. The primary difference here is that Nagel’s work does not go on to endorse a theistic solution.

Silver bullets…?

Nagel spends the first two chapters of the book – about 30 pages – outlining the high-level view of his concerns with naturalism. It is here that he introduces us to the “failure of psychophysical reductionism” and identifies three ways in which this failure is realized: in theories of consciousness, cognition, and value – each of which serve as the titles for the substance of the argument in the next three chapters. By this point the territory had grown familiar and I couldn’t help but wonder whether Nagel was fully aware that his thesis mirrors three of the most philosophically prominent arguments for the existence of God. He cites contemporary secular philosophers, such as Sharon Street, as his primary interlocutors yet on the theistic side we get little more than a single footnote reference to Plantinga’s “Where the Conflict Really Lies”. Whereas the apologetic versions of these arguments essentially all boil down to “Nature cannot produce (or access) X, thus God.”, Nagel is affirming everything before the comma and leaving everything after as an open question; though he does prod us toward accepting the possibility of an impersonal teleological force. Nevertheless, allow me to summarize his points and show how they couple into the case for theism.

Consciousness

What it's like to be a batHere we find Nagel reaffirming ‘the hard problem of consciousness’, as he has done in the past. In his 1974 essay “What is it like to be a bat?” he closed with the statement that “it seems unlikely that any physical theory of mind can be contemplated until more thought has been given to the general problem of subjective and objective.” 38 years later, this chapter takes it a step farther and suggests that the subjective cannot be reduced to the physical:

“if Ψ [a mental event] really is Φ [a physical event] in this sense, and nothing else, then Φ [a physical event] by itself, once its physical properties are understood, should likewise be sufficient for the taste of sugar, the feeling of pain, or whatever it is supposed to be identical with. But it doesn’t seem to be. It seems conceivable, for any Φ [physical event], that there should be Φ [a physical event] without any experience at all” (pg 41).

In the next section this conclusion is then applied to the evolutionary story:

“Since a purely materialist explanation cannot do this [explain the appearance of conscious organisms], the materialist version of evolutionary theory cannot be the whole truth” (pg 45).

To put it briefly, the ‘hard problem’ amounts to the difficulty we have in translating the experiential (qualia) to the descriptive, and it seems clear that any physical explanation is inherently descriptive. To this the theist agrees and then asks, “What now?” The God answer has most notably been advanced by Richard Swinburne (see The Existence of God) and J.P. Moreland (see Consciousness and the Existence of God).

Disclaimer: These two books are on my list but I have not yet read them and am working from the content available online. Reader beware (even though I may have stumbled into full versions of the texts).

These heavyweights of Christian philosophy propose that consciousness is not only incompatible with a purely physical cause but that its very nature begs for a personal cause that is itself conscious. Why? To quote Moreland,

“on a theistic metaphysic, one already has an instance of consciousness and other mental entities, e.g. an unembodied mind, in God. Therefore, it is hardly surprising that finite consciousness or other mental entities should exist in the world. However, on a naturalist view, mental entities are so strange and out of place that their existence (or regular correlation with physical entities) defies adequate explanation. There appear to be two realms operating in causal harmony and theism provides the best explanation of this fact.”

Swinburne starts with the same assumption and then makes this being personal and gives him motivation for creating us by appealing to the moral capacity of conscious beings, wherein beings which can choose to do good are a valuable addition to the universe. Good activities include relationship and love and so the origin of consciousness should have these qualities as well.

If we grant that consciousness cannot arise from the physical then I honestly think I would favor the apologist’s proposition. If consciousness truly is something fundamentally significant and distinct from physical reality then explaining its origin in terms of an advanced, transcendent consciousness seems more sensible than positing a disinterested or unintentional source. This may not get us to a particular formulation of what that transcendent consciousness is, but it leads the way to further discussion. Regardless, the obstacle lies in that first clause – in establishing the failure of the naturalist account.

Cognition

“We take ourselves to have the capacity to form true beliefs … We don’t take these capacities to be infallible, but we think they are often reliable, in an objective sense, … human life assumes that there is a real world … and that there are norms of thought which, if we follow them, will tend to lead us toward the correct answers. It assumes that to follow those norms is to respond correctly … It is difficult to make sense of all this in traditional naturalistic terms.” (pg 72)

Nagel goes on to grant that it does make sense from an evolutionary perspective for our faculties to accurately represent the world. Even more, he cogently describes the standard evolutionary explanation for cognition through the adaptive benefits of the mental faculties that enable us to generalize and symbolize and, at the end, acknowledges that the story as a whole is not impossible. Section 3 then commences with the deconstruction.

The first criticism raised is the circularity of reliance on our reasoning. He points out – and correctly so, in my opinion – that when we evaluate the evolutionary story and find it to be an adequate explanation of our capacity for reason, we are in fact relying on that very explanation in the process. The second shot is aimed at our ability to discern truth. Whereas consciousness may render a generally accurate picture of our immediate environment, reason allows us to step out of our subjectivity and compare and contrast data from an objective standpoint to locate truth. The reasons why we might see this as an obstacle to physical explanation are less clear and largely intuitive: “it does seem to be something that cannot be given a purely physical analysis and therefore, … cannot be given a purely physical explanation.”

CS-LewisNot long ago I read C.S. Lewis’ Miracles. The first half of the book says very little about miracles and purposes instead to set the stage for the allowance of the supernatural. His central argument for the existence of something which transcends the material was an examination of Reason and our ability to utilize it. This has come to be known as the argument from reason (which is actively defended by Victor Reppert at dangerousidea.blogspot.com). The argument can be summarized as “How can the rational come from the irrational?” It builds upon our intuition, crafted by our experience, that the unconscious world is generally not oriented toward truth. Nothing in random natural processes seems to work toward discerning correctness. Why should evolution have ended up with something that did?

Plantinga’s evolutionary argument against naturalism argues the same position with a bit more philosophical depth and with the addition of the circularity observation that Nagel poses. I already discussed this argument a bit in a review of “Where the Conflict Really Lies”, so I won’t rehash that here. Regardless, both Lewis and Plantinga go on to suggest that if reason cannot be explained by the physical realm then the most sensible conclusion is that its presence in our world has its origin with something that is itself capable of reason, and which values rationality, and thus bestows that value upon us. Again, I find that this is a reasonable option if we agree that rationality necessarily transcends the physical. As before, it may not be the only conclusion but it is a strong and viable candidate.

Value

Nagel’s final concern with the physicalist paradigm rests on value realism. His opening section again acknowledges that the target, this time the subjectivist account of value, is “not flagrantly implausible.” The subsequent section continues to discuss the distinction between subjectivism and value realism and then interestingly closes with a concession about the case for value realism:

“There is no crucial experiment that will establish or refute realism about value… Positive support for realism can come only from the fruitfulness of evaluative and moral thought in producing results, including corrections of beliefs formerly widely held and the development of new and improved methods and arguments over time. The realist interpretation of what we are doing in thinking about these things can carry conviction only if it is a better account than the subjectivist or social-constructivist alternative, and that is always going to be a comparative question and a matter of judgment.” (pg 104-105)

This seems to indicate that he thinks that our recognition of progress is the best indicator of value realism; but he also recognizes that the identification of progress is itself subjective. Ultimately Nagel grants that his grounding for the objectivity of value is purely an intuitive feeling and, as such, very little time is spent defending that conclusion. Instead, Nagel spends the next couple chapters outlining his agreement with Sharon Street in her proposal that a purely Darwinian account of evolution is incompatible with value realism (see A Darwinian Dilemma for Realist Theories of Value).

It’s probably painfully obvious how this relates to the theistic worldview. I don’t think I’m going out on a limb if I propose that the moral argument is among the two or three most important and widespread arguments for God’s existence. It was a favorite of C.S. Lewis, and nearly every apologist thereafter. Francis Collins indicated that it was the key factor in his conversion. Briefly, the moral argument says that moral value exists independent of our opinion. Some things, like the oft cited “torturing babies for fun”, are truly wrong regardless of what we think. The theists then take the next step and ask where these moral truths come from. They do not appear to be a material part of the world and yet regularly guide our actions and serve as the explanatory foundation of our reasoning – which is the key to the theists proposition. When we keep asking why, we will usually eventually hit a wall made entirely of value judgments. If the answers to the “why” questions are not found in the answers to the “how” questions, and we are the only part of the physical realm which seems to care about the “why”, then the origin of those values is reasonably accounted for in something capable of valuing – something intentional and teleologically motivated.

For the sake of argument, lets grant the assumption of moral realism. When I take this stance, I am compelled to agree with the problems it poses for a undirected evolutionary account of our moral disposition. As I thus proceed to examine the alternative explanations for its existence, here again I find myself appreciating the theistic answer. Why? Because value seems to be intrinsically tied to intention, and intention infers purpose and an agent pursuing that purpose. If value is independent of humanity then it makes sense that it be grounded in something that retains intention and purpose. Without this, it would seem, value loses its value.

…or misfires?

But, in the end, I am unpersuaded. As indicated by the quotes from the book, the rejection of the naturalist explanation appears to be intuitively driven speculation on what is possible within the framework. Yes, the naturalist position on these topics is also speculative, but it is utilizing the world as we know it and trying to minimize additional assumptions. Accordingly, there are several points of momentum carrying the naturalist explanation, and I contend that the current is strong:

  1. There is a continuum of mental faculties in the animal kingdom. It seems that we can incrementally walk down the chain of neural complexity until the brain essentially becomes a scrutable set of chemical reactions. There is no obvious reason why we should draw a line somewhere and start assigning significance.
  2. Neuroscience has made it abundantly clear that the mental is, at the very least, co-dependent on physical aspects of the brain. If this much is indisputable then it seems extraneous to postulate something more when there is a readily identifiable explanation for our lack of complete understanding; namely the complexity and inaccessibility of the living brain. The insistence that qualia cannot be reduced to the physical seems to be begging the question. See my brief comment on the ontology of qualia for more on the relation between the physical and the mental.
  3. The naturalist program hinges on regularity. So far, in the course of history, we have identified regularities in the underlying explanation of nearly everything and the only exceptions bear the distinction of unresolved complexity – we see the regularity of the underlying parts, but have not unraveled their cumulative behavior. We have not yet, to my knowledge, identified anything which is simple yet unpredictably irregular. Is it not reasonable to suspect that this trend will continue? If there truly is a teleology shaping the world then it is an odd coincidence that it only manifests within instances of unresolved complexity.
  4. Aside from the possibility that the physical parameters of the universe were fine-tuned at its birth, the universe as a whole does not obviously have the appearance of one in which a powerful, directive force or being is actively working toward the goal of consciousness, cognition and value. Conversely, the universe is overwhelmingly void of these things and seems indifferent to their permanence. It is conceivable that there are universes in which the life that sustains consciousness, cognition and value is less fragile, or in which the environment better supports that life. If Nagel’s teleologic force is constrained in its capabilities, or if I have misapprehended the possible set of life valuing universes, then this objection would disappear.

Accordingly, I simply do not see how a non-teleological evolutionary theory fails to enable consciousness, cognition and value. Physical reproduction is inherently dependent on the acquisition and manipulation of material that is external to the replicating being. A reproductive process which never replenished or adopted outside material would quickly come to an end. This means that accurate interaction with the outside world is imperative to reproductive success. Any system which does this better than its ancestor is more likely to flourish. Accordingly, what may have started as the most simple of interactive functions would be expected to improve as change creeps in. Eventually, the combination of consciousness and cognition yields the coordination of multiple external stimuli, an increased sample size by incorporating past experience, the projection of the past to the future to guide anticipatory motor control, and a generally accurate inference of the external world beyond our immediate perception. The associative machinery in our brain builds links based on real world input and so, when those links strengthen one interpretation over another, we favor it as truth. As more experience and information is added to those links the probabilities of aligning with truth increases and we gain an advantage in navigating the world. Finally, add the development of an innate bias toward that which is most beneficial to our survival and reproduction and out pops “value”. To top it all off, if those values are rooted in a common ancestry then they will be perceptually objective to the descendents.

The most inescapable criticism of this “just-so story” lies within the circularity of the naturalistic origins of our capacity to reason. I contend, however, that this is not limited to the naturalist. Everybody, it would seem, is trapped in this vicious circle. We necessarily start from a position of pragmatic reliance on our rational capacities and form our theory of its origin thereafter. Where the naturalist says “it’s reliable because it benefits survival”, the theist says “it’s reliable because God would not deceive”. Both parties have assumed the reliability of their cognition as a prerequisite to determining why it is reliable.

There is also definitely an intuitive appeal to the doubt that rationality can in some way arise from the irrational. Furthermore, this isn’t a concern that the naturalist can expunge with new evidence and further discovery. If the naturalistic explanation is true then this objection is here to stay and will only be reinforced as we learn more. I do not see, however, why it necessarily renders the story invalid. If all the evidence falls in line then we just have to accept where it points. Diverging from the evidence is a far less attractive option.

I commend Nagel for his continued willingness to think outside the box, go against the grain and challenge our assumptions. We all need to do this on a regular basis and society will never progress without those select few who break from the status quo. Even so, those ventures are only successful if they correspond with the reality of our world. It’s possible that I am among the masses who have been caught up in a false current and I am simply unable to see that I have been blinded to the faults of the “materialist neo-darwinian conception of nature” but, if that is so, then Mind & Cosmos has done nothing to snatch me from the rapids.

My Ontology – Part 2: Mind-dependence

Open MindIn Part 1 I laid the foundations for my ontological framework and came to the conclusion that my position is currently best categorized as that of conceptualism. In this post I would like to dig into this deeper and examine some of the key issues surrounding the topic of mind-dependence and some of the arguments against the conceptualist view. What does it mean to say that a mind-dependent thing (hereafter referred to as a concept) exists? Some may initially balk at the prospect that concepts actually do exist in some sense, but I think our experience infers our acceptance of this proposition on a regular basis. I suggested in Part 1 that we often include concepts when we speak of things which exist. In addition, we routinely say that we “have an idea” and we can recognize the feeling of “getting it” when an explanation “sinks in”. We have a word “on the tip of our tongue” when we are aware of the concept but unable to express it. A placebo can change our well-being. It seems to me that these are all manifestations of concepts.

In the entry on Platonism, the Stanford encyclopedia of philosophy states that “[conceptualism] has serious problems and not very many people endorse it.” Chris Swoyer suggests that conceptualism warrants renewed consideration and starts by noting that “Somewhere in the twentieth century… conceptualism fell off the map….it’s surprising it continues to receive even the perfunctory nod it often gets…”. As an alternative many either come to accept that these things I call concepts are actually mind-independent (realists) or that they don’t exist at all (nominalists). I hope that in this post I am able to make the case that conceptualism has been overlooked. Of course, it is also possible that somebody will come along and straighten me out and make me realize that I’m actually a nominalist or a realist; but we won’t know unless we try.

A naturalist account of concepts

As it currently stands, I find that the naturalist account of reality is more probably true than the Christian (or theistic) perspective I once held. This means that I should be able to reconcile naturalism with the ontology that I have proposed. The naturalist position unashamedly equates the mind with the brain, and so the existence of concepts must be defined within that context.

neuronsTo start this exploration, I want to re-iterate a perspective that I have offered before. In Part 1 of my epistemology, I proposed that logical reasoning can be explained as a process of mapping relations between experiences (and the labels assigned to those related portions of our experiences) and in the end I came to the conclusion that I am an empiricist. Similarly, in Part 1 of this series, I argued that experiences define our knowledge of objects and thus inform our ontology. Taken as a whole, this perspective appears to be highly compatible with our modern understanding of the brain. Allow me to try and briefly outline this congruence.

First, we are well aware that the brain is highly associative. We regularly employ mnemonic devices to improve our recall, and basic introspection reveals how our train of thought tends to follow along paths which relate concepts. Second, we know that the brain is a somewhat flexible configuration of what is very roughly estimated to be 100,000,000,000 neurons and 1,000,000,000,000,000 synaptic connections, where by “flexible” I mean that the connections can change. The neurons and synapses combine to form neural networks that, as far as we can tell, serve to encode sensation and train our response. Sense data, both external and internal interfaces with the brain and causes the relevant neural networks to update accordingly. Obviously all of this is a rather gross simplification and so, when coupled with the fact that my knowledge of neuroscience is both limited and informal, you would be wise to investigate these things further on your own. Regardless, all of this leads me to a rather simple definition of a mental concept: with each experience our brains are modified with a “shadow” of the sense data from that experience. These shadows are linked with each other (perhaps even shared in some way) when the sense data is phenomenally or temporally similar. Symbols associated with these experiences become linked into the networks, tying words into the mesh. The result is a massive network of neural relations that can be broken into symbolically identifiable segments, where each segment represents a discreet aspect of one or more experiences. This defines a concept. They can be linked to define new, more complex concepts, or dissected to define simpler concepts. The following TED talk (20 min) offers a glimpse into this amazing network.

So, to put it simply, concepts are patterns in the brain. These patterns are byproducts of our experiences and genetics, and persist with varying fidelity. As a result, they are unique to each individual. The sensory encoding process for humankind, however, is generally the same. The resulting patterns then share enough commonality, and relations to symbols, that we are able to agree on the external reality from which they were formed. We communicate this to each other primarily through the use of the word symbols linked to the concepts.

Now lets take this idea to its natural conclusion. If mind-dependent things are really just patterns in the brain, then what is this thing that we are calling a pattern? As I see it, there are two options under this framework: either patterns are themselves something independent of the mind and are a foundational part of all concepts, or patterns are themselves patterns. The first seems to be a theoretical leap based on nothing but the fact that we’ve hit the end of our rope. Alternatively, the second option puts us into an interminable self-referential loop (aka, recursion). While there is something disquieting about this, I am at a loss to explain why it is in any sense invalid. In fact, this may be the only kind of infinite that exists. As a software engineer, I myself have on rare occasion created these interminable self-referential loops. There are other reasons to prefer the self-referential option. For one, we intuitively identify a pattern as an abstract object. It only makes sense, then, that it would remain as such. Recursion also makes sense when you consider the neurophysiology outlined above. If concepts exist within a massive web of interconnectivity, then the potential for self-reference should come as no surprise. I have here breached a rather massive topic to which many are devoting entire lives, yet I shall leave it at that. It is only necessary at this time to define the foundational ontology of concepts for the purpose of further scrutiny.

Objective relations

Mt. Everest, Lhotse, Nuptse

The Stanford article on platonism suggests that one of the stronger objections to conceptualism can be summarized as follows: “…relational claims seem to be objective; e.g., the fact that Mount Everest is taller than Mont Blanc is a fact that holds independently of us; but conceptualism about universals entails that if we all died, it would no longer be true that Mount Everest bears the taller than relation to Mont Blanc, because that relation would no longer exist.”

I may have fried a few neurons thinking about this one. I was at first inclined to suggest that this was no different than my thought experiment in Part 1, where I proposed that the only reason the story of Paul Bunyan seems to survive the death of its lone storytellers is because the concept of the story remains in my mind. Similarly, I thought, the “taller than” relation (and similar relations) only appear to be objective because the concept remains in our mind when we consider the example. It then occurred to me, however, that there is a key difference to be taken into account. The “taller than” relation would seem to be clearly discoverable without having ever been transferred from another mind. In some sense, it appears that the relation is not completely mind-dependent.

So I started working from the ground up. I asked myself what it means when we say that something is “taller than”. I concluded that we are expressing a perceived difference in the amount of space the objects occupy in the vertical dimension. This space is a quantifiable, observable object. So the “taller than” relation actually has a referent – the space that is occupied by the taller object and is not occupied by the shorter object. I am venturing to propose that this holds for all objective relations. For example, “brighter than” refers to the photons emitted by the brighter object which are in excess of the photons emitted by the dimmer object. “Faster than” refers to the change in space-time covered by the faster object that isn’t covered by the slower object. The examples could go on and on. If you have a counter-example of an objective relation that has no referent in the physical world (i.e., space / time / matter / energy), please send it my way.

What does this mean? It means that objective relations are very much like concrete particulars and their corresponding universals. The particulars are differences which correspond to quantitatively identifiable aspects of the physical world that we experience. These experiences are then linked together in generalizations that we assign labels. The “taller than” relation is an effective and convenient shorthand for expressing differences in the amount of vertical space occupied by objects, just as calling something a table is an effective and convenient shorthand for referring to all our past experiences of similar objects. So it would seem that the ontology of objective relations should be viewed no differently. If all minds are extinguished then the universal concept of a table no longer exists, but the particular table objects remain. Likewise, the generalized concept of a “taller than” relation does in fact disappear when all minds are extinguished, but the particular instances of physical differences do not.

The problem of universals

If I have thus far explained myself well, it should already be obvious that I see universals as concepts in the mind. Even so, it would be careless for me to summarily dismiss it on that note. Conceptualism, some say, doesn’t address the problem of universals. To quote from the Internet Encyclopedia of Philosophy:

Conceptualism’s appeal to concept application must concern only correct concept application. As such, it is fair to ask, “What makes it the case that the concept red is rightly applied to both a and b, but not of some third individual, c?” To treat this fact as brute and inexplicable is to revert to problematic Predicate Nominalism. So it seems the Conceptualist must say that the concept red applies to a and b, but not c, because a and b share a common feature, a feature c lacks. Otherwise, the application of red is unconstrained by the individuals to which it applies. But simply noting that a and b resemble each other isn’t going to help, because that just is the fact we originally sought to explain, put differently. The Conceptualist might now say that a and b share a property. But if this isn’t to amount to a restatement of the original datum, it must now be interpreted as the claim that some entity is in both a and b. That, of course, turns our supposed Conceptualist strategy back into Realism. Critics say Conceptualism solves no problems on its own. In trying to ground our right to predicate the concept red of a and b, we are driven back to facts about a and b themselves and that leaves Conceptualism as an unstable position. It teeters back and forth between Realism, on the one hand, and Nominalism, on the other.

I suspect that this objection is levied against a form of conceptualism in which concepts are not formed through experience. Allow me to try using the proposed framework to answer the key question of this objection: “What makes it the case that the concept red is rightly applied to both a and b, but not of some third individual, c?” Answer: There is a frequency range in the electromagnetic spectrum for which objects a and b emit or reflect light and object c does not. The sensory input from electromagnetic waves in that range is associated with neural structures that collectively form the concept of redness, and we call this concept “red” because those structures have further associations with the word “red”. The sensory input from object c does not create the same associations and so the concept of “red” is not applied to it. At the risk of sounding pompous, it seems to me that the discussion ends there. Have I missed something?

“Red”, as a universal, can be easily associated with particulars, namely the electromagnetic waves in a certain frequency range. When the universal in question is the type which is a categorization of particulars (e.g., red, table, chair, etc…), the application of conceptualism is clear – the universal is the concept that links our experiences of the particulars together. There are other types of universals, however, which assign properties to objects and that have no obvious referent. We might say that something is hot, flat, smooth or loud. How do these types of universal properties fit into the conceptualist framework? The answer lies in the discussion of relations above. The similarity between relations and these types of property universals becomes clear upon consideration of what these properties are really saying. When we say that something is hot or cold, flat or steep, smooth or sharp, or loud or quiet, we are in fact expressing a relation to the norm, or a relation to other spatially or temporally nearby objects. If we’re standing in a walk-in freezer then we might say that an object at 10° C is warm, but we might say that the same object is cold if we are in a stifling equatorial jungle. A knife is sharp because most objects don’t have edges that cut, but a knife can be dull if it doesn’t cut like it used to. These are all relations and, as previously discussed, that means that they all have particular referents in the physical world from which the experiences combine to form concepts.

Qualia

Mary the color scientist Mary is a brilliant scientist who is, for whatever reason, forced to investigate the world from a black and white room via a black and white television monitor. She specializes in the neurophysiology of vision and acquires, let us suppose, all the physical information there is to obtain about what goes on when we see ripe tomatoes, or the sky, and use terms like ‘red’, ‘blue’, and so on. She discovers, for example, just which wavelength combinations from the sky stimulate the retina, and exactly how this produces via the central nervous system the contraction of the vocal chords and expulsion of air from the lungs that results in the uttering of the sentence ‘The sky is blue’.… What will happen when Mary is released from her black and white room or is given a color television monitor? Will she learn anything or not? It seems just obvious that she will learn something about the world and our visual experience of it. But then is it inescapable that her previous knowledge was incomplete. But she had all the physical information. Ergo there is more to have than that, and Physicalism is false.Frank Jackson, Epiphenomenal Qualia (1982)

The “knowledge of” entails a completely different kind of pattern in the brain than does the “experience of”. Setting aside the likelihood that color concepts do not consist of the exact same pattern in each person, the knowledge that Mary possesses is only present in the form of the patterns of the information she has acquired through her research. According to the story, the pattern which results from the stimulus of the wavelengths themselves was never realized. So, yes, she does “learn” something new. Now, we could perhaps propose that Mary not only knows how to translate sensory experience into neurophysiology but also has the incredible ability to manipulate her own neurology accordingly. In this case, I would propose that the problem has gone away. Mary has induced the experience of color independent of the actual visual reception of color. She would now have the patterns of color experience encoded in her brain and will thus have created the qualia in the same way that actually seeing it would have.

Who cares?

Door to...

Good question. As I noted at the outset, it wasn’t long ago that I would have considered these musings to be pointless and absurd. What I’ve come to find, however, is that this all actually plays a significant role in the God debate. Why? Because if some type of realism is true, and it can be said that even some small subset of abstract objects or universals exist on their own, then we have accepted the independent existence of the immaterial. This in itself is not necessarily troublesome for the naturalist position. After all, science is in the business of discovering new aspects of “nature” that were previously mysterious. There does seem to be a difference this time, though. If these things exist, and we know about them, then the implication is that we have accessed them in some non-empirical way. This accessibility elevates the mind to a privileged position which gives it access to things in a way that isn’t found anywhere else in nature. Furthermore, the current reckoning of the naturalist position would infer that this special access came about as the result of blind evolutionary forces acting on material that didn’t yet have any interface with these things. Is that just a coincidence?

To the theist, this is the gateway to further interrogation into the immaterial realm (God, soul, spirit, free will, etc…). To the naturalist, this is a crack in the door that was supposed to have been closed. While it may not serve as evidence for God, it would suggest that there is more to reality than the naturalist is typically willing to grant. There’s no telling what all lies behind that door. Of course, this potential conflict is no reason to avoid the questions and shun sensible answers. We should pursue truth wherever it may lead.

With that in mind, you may have noticed that I have skirted some of the big questions. I am ending this two part series having merely outlined my perspective on what is means to say that something exists while showing how, within the conceptualist paradigm, there does not appear to be any problem reconciling the existence of mind-dependent objects with a naturalistic account of reality. By aligning myself with conceptualism I have inferred that abstract objects exist only by virtue of their mind-dependence, but I have avoided asking whether or not some things (morality, mathematics and, of course, God) are truly mind-independent. That said, I believe that this framework presents a coherent mechanism by which we may suggest that they are mind-dependent. Even so, those will have to be addressed another time; perhaps after much more contemplation. I do not yet feel comfortable with any one position on these, among others, and this should not be a surprise. We have been debating these things for centuries. In the end, I will openly concede that a deep dive into those topics, or a persuasive refutation of my reasoning here, could potentially turn this entire framework on its head. And that is where you come in. Please, dear reader, tell me why I’m wrong.

My Ontology – Part 1: Foundations

John Stuart Mill

The tendency has always been strong to believe that whatever received a name must be an entity or thing, having an independent existence of its own; and if no real entity answering to the name could be found, men did not for that reason suppose that none existed, but imagined that it was something peculiarly abstruse and mysterious, too high to be an object of sense. The meaning of all general, and especially of all abstract terms, became in this way enveloped in a mystical haze.

John Stuart Mill in Analysis of the Phenomena of the Human Mind

Not too many years ago I probably would have placed ontological discourse under the category of “pointless and senseless blather”. I say this not to denigrate the subject matter but rather to expose the naivety with which I constructed my worldview. That said, the John Stuart Mill quote does well to capture my current sentiment. Though I still find myself bewildered by certain ontological perspectives, I cannot escape the ramifications therein and so I am obliged to make an effort to address the topic.

I think it’s worth repeating the disclaimers that I offered when I presented my epistemology:

Disclaimer #1: I have no formal philosophical training, so forgive me if I abuse the terminology and/or overlook well established points and counter-points. My goal is not to educate others on philosophy, but to work through and explain the current state of my own view of ontology. This is armchair philosophy.

Disclaimer #2: I am trying to avoid using complicated and confusing language, but that is not always easy in these types of discussions. I apologize in advance if I have failed in that endeavor. I’m almost certain that I will.

First things first

I’m not sure that I could have given you the definition of ontology if you had asked me three years ago. I am now all too aware that ontology is the branch of philosophy which deals with the nature of existence. My journey over these last couple years has introduced me to the world of the existential, a land which was utterly foreign to me before I began to question my foundational assumptions. So, when I set forth my epistemic framework some time ago (see Part 1 and Part 2) I never considered the possibility that I was doing things out of order. According to some there is a very simple explanation for why our ontology (theory of existence) must precede our epistemology (theory of knowledge). They would suggest that we must assert that something does or does not exist before we can say that we know anything about it. On the surface this seems like a fair proposition, but then I am compelled to ask how it is that we can say whether something exists, or the form of its existence, without considering how it is that we even know about that something? As far as I am concerned the entanglement between ontology and epistemology is too deep to warrant any claims that one is prior to the other. I am tempted to leave it at that but it seems appropriate to examine this further with an example.

Frequent exposure to philosophical discussion over the last few years has bred familiarity with certain ‘pet’ scenarios and examples. When it comes to ontology, it seems that tables and chairs have been favorites for centuries. I shall continue the tradition to investigate the relation between the epistemology and ontology of tables. This starts with a brief thought experiment.

Suppose a child grows up in a house where the only tables in the house are square, four-legged tables which are set up on their side. A wire is run between the legs and used to hang clothes for drying. Suppose this child is never exposed to any other use of tables. Upon discovering the neighbors sitting and eating at a four-legged table, she may or may not recognize that it is a table but, if she does, she will suppose that it is being used in a strange way. Alternatively, upon seeing a neighbor sitting at a circular pedestal table the same child will almost certainly fail to recognize the object as a table at all because (a) it doesn’t look like the tables she knows, and (b) it has no obvious utility for running wires to dry clothes even if it were set on its side.

At this point you may be wondering if I have drifted off into a confusion between semantics and ontology but I hope to link this all together, so bear with me. The point of the ridiculous thought experiment above is to see that words, like ‘table’, are a type of expression of our experience, or what philosophers refer to as ‘qualia’. To say that something exhibits the property of ‘tableness’ is to say that it is a fair approximation of past experiences with other objects that have been labeled as tables. Words give us a way to relate those experiences between each other and this is most evident where one person’s association of a word to an experience is very different from another person’s association, even if they talking about the same physical object. Our qualia of tables includes both sensory perception of the table itself (color, texture, shape, etc…) but also relational observations (how tables are used, where they tend to reside, etc…). As the number of experiences with tables grows, so does our understanding of ‘tableness’.

While we are reliant on experience to develop a concept of ‘tableness’ we also generally expect that tables exist in the world regardless of whether we ever experience them. But I contend that this expectation only exists because we have already experienced tables, or similar objects, as independent and persistent entities; our experiences enable us to comprehend what it means for tables to exist. If we ignore this, that is, if we suppose that existence can be comprehended without any relation to experience then it would seem that existence itself becomes an incoherent concept. I cannot escape the conclusion that our comprehension of the existence of tables (ontology) cannot in any coherent way be separated from the knowledge of tables (epistemology), yet our knowledge of tables (epistemology) is apparently dependent on their existence (ontology). You cannot claim one without the other. Our ontology is necessarily informed by our epistemology. Attempts to deduce ontology independent of epistemology are actually relying on epistemology while at the same time claiming to ignore it.

Disclaimer #3: Lest it should appear that I am addressing a particular work, please note I wrote and titled this section before encountering James W. Sire’s book “Naming the Elephant: Worldview as a Concept”, which contains a chapter entitled “First Things First” that is an evangelical argument for ontology prior to epistemology (and which can be read on Google books). He considers views where ontology comes first and where epistemology comes first, but never one in which they cannot be prioritized relative to each other. I guess we disagree.

Defining existence

Plato's cave

In the previous section I did not discount the possibility that ‘tables’ exist as something separate from any particular instance of a table. That is, to say that we have experienced ‘tableness’ may allow that we experienced something distinct and possibly independent from the tables themselves. I have just waded into some deep and murky waters and sanity requires that we review some definitions.

We can broadly split all ontological positions into two groups:

  • Realism: The position that something exists.
  • Anti-Realism: The position that something does not exist.

Simple enough. We typically apply ‘realism \ realist’ and ‘anti-realism \ anti-realist’ as qualifiers for a category of things (e.g., moral realist, mathematical anti-realism, etc…). For the most part this distinction isn’t very interesting until we start talking about abstract objects and universals. It is here where we open the proverbial can of worms, so I need to proceed by first defining the main categories of “things”. As it is with all philosophical language, there is widespread disagreement about definitions; and fringe cases abound. Regardless, this is what I understand to be the majority perspective:

  • Concrete Object: Something which can be located in space and time.
  • Abstract Object: An idea, non-physical representation or categorization.
  • Individual (or Particular): A singular instance of an object. (Wikipedia says that ‘particular’ is the adjective and ‘individual’ is the noun, but I find that they are actually used interchangeably in practice).
  • Universal: A quality or property which is common between individual objects.

I find it especially true in philosophy that examples are invaluable for clarifying definitions. The following table tries to offer some examples that show the relationship between the categories given above.

Concrete Objects Abstract Objects
Particulars
  • The pixels in the shape of a 7 on your screen
  • My dining table
  • An electromagnetic wave with a 520nm wavelength
  • Tonight’s sunset as viewed from your house.
  • The number 7
  • The table described in a fictional story
  • The green I see in my front yard
  • The beauty of tonight’s sunset
Universals Empty?
  • Numbers
  • Tables \ Tableness
  • Green \ Greenness
  • Beauty

There are several points of contention here. The most obvious is whether anything should be categorized as a concrete universal. Somebody might also argue that “the green I see in my front yard” is just a synonym of “an electromagnetic wave with a 520nm wavelength” – but philosophers will often suggest that the qualia of ‘green’ is something different; we’ll touch on this more later. Regardless, now that we have a set of words to describe the possible constituents of reality, let’s look at the ontological positions that have historically been held:

  • Realism \ Platonism: The position that abstract objects and universals exist on their own in addition to concrete particulars.
  • Conceptualism: The position that abstract objects and universals exist only as a concept while concrete particulars exist in and of themselves.
  • Nominalism: The position that abstract objects and universals don’t exist whereas concrete particulars do.
  • Idealism: The position that everything exists only as a mental concept. In a sense, there is no “physical” world.
  • Nihilism: The position that nothing exists. No need to discuss this further then, eh?

Having laid all of these definitions out it immediately becomes apparent that there’s a huge problem: every definition relies on an agreement as to what it means for something to exist. At first blush, existence appears to be defined by the set of things which we say exists, but that type of definition will just make us dizzy (if you weren’t already). So, to start, I want to narrow down the concept of existence a bit. At the risk of confusing things further, I want to bring two more categories into play: mind-dependent things and mind-independent things. Mind-dependent things are those which are only identifiable as conceptions of the mind. Fictional characters like Paul Bunyan and Captain Kirk are clear examples. Depending on your ontological position, certain abstract objects may or may not also be examples. Mind-independent things are those which can be said to exist even if there is no mind, like Ayers Rock, the keyboard I’m typing on or the screen you are reading this on. They are “out there” and can be discovered or accessed by minds. We generally agree that all concrete particulars are mind-independent things. A moral realist would also say that morality is mind-independent and an idealist might say that nothing is mind-independent (except perhaps God).

Paul BunyanNow, to define existence, I want to examine how it is that we use the word in our everyday practice. In my experience we will generally agree that things which are mind-independent can be said to exist. The remaining question, then, is whether that completes the set of things which exist or whether there are cases in which mind-dependent things can also be said to exist (setting aside the question of which things are mind-independent). Probing this further, it is also my experience that we will generally agree that certain mind-dependent things do not exist. We will generally agree that Paul Bunyan the person does not exist, but what about Paul Bunyan the story? My intuition tells me that I should say that Paul Bunyan the story exists but that Paul Bunyan the person does not. What is the distinction? Time for another thought experiment.

Consider a scenario where the story of Paul Bunyan exists only in the oral tradition of an isolated tribe. The story is never reproduced except through verbal communication between the tribe’s members. Imagining myself as a member of this tribe, I find it very easy to say that the story of Paul Bunyan exists. Now suppose that a nasty virus sweeps through and kills every member of the tribe (and that ‘mind’ does not survive the body). Would I still say that the Paul Bunyan story exists? I am inclined to answer yes, but only because I know that it was at one time part of a mind. If you instead asked me whether the Luap Naynub story exists and could tell me absolutely nothing about it and could not even explain why you asked that question in the first place then I am inclined to say that it does not exist. The difference is that in the first case the knowledge of the story’s existence survives in my mind (even if I don’t know any details of the story – which almost certainly means its existence in my mind is vastly different than its existence in the context of the tribe) and in the second case there is no identifiable mind, past or present, in which the knowledge of the story exists. I can see no difference between mind-dependent things which do not exist and mind-dependent things which are universally unknown. I then find myself with a few options. Either mind-dependent things:

  1. Never exist (and my intuitions about the existence of the story of Paul Bunyan were incorrect), or
  2. Come into and out of existence (under an A-Theory of Time), or
  3. Exist if they ever have been, are, or will be synthesized in a mind (under a B-Theory of Time), or
  4. Always exist for all possibilities (and are “out there” waiting to be discovered).

I propose that the 2nd option is the best fit for our everyday understanding of existence, with the 3rd option as the equivalent formulation under a B-Theory of time. It appears that this definition applies equally well to mind-independent things.

OK, so what about Paul Bunyan the person? Why don’t we say that he exists? Let’s look at this through the lens of concrete versus abstract objects. The story of Paul Bunyan is a particular of the universal type “story”, and particulars of type “story” are also abstract. We are content to say that abstract objects exist as mind-dependent things, so it makes sense to say that the story of Paul Bunyan exists. However, the person of Paul Bunyan is a particular of universal type “people”, and particulars of “people” are concrete. If we say that a concrete object exists, we expect it to be mind-independent, and we have no reason to believe that Paul Bunyan the person is mind-independent (and good reasons to doubt it). This means that there is a problem if we say that Paul Bunyan the person (a concrete object) exists. The solution, then, is to say that he does not exist. Conversely, we can accept the proposal that the idea of Paul Bunyan the person does in fact exist, because now the particular is the idea (an abstract object), not the person (a concrete object).

So this is where I will settle. I will use “exist” to indicate that something is a constituent of reality even in the absence of mind (i.e., it is mind-independent) or that it is identifiable as a concept within a mind. This approach unfortunately requires that we qualify whether we are speaking of concrete existence or conceptual existence, but that is simply an artifact of language. Finally, note that the actual substance (if there is any) of abstract objects is tangent to this and can be safely ignored for the purposes of defining existence this way. If I then had to classify myself according to the ontological positions given above, I suppose this means that I am a conceptualist.

In Part 2 I take a closer look at mind-dependent things and how I think that a naturalist can plausibly account for their existence. It may be fair to say that this post (Part 1) is just a primer for the discussion there.

Moral anti-realism and the problem of evil

Italianate_Landscape_with_an_Artist_Sketching_from_NatureOn several recent episodes of the Stand to Reason podcast, Greg Koukl has argued that those who do not hold to moral realism cannot put forth the problem of evil as evidence against the existence of God because, in short, they cannot define evil. J. Warner Wallace makes the same claim in Cold Case Christianity. They tie this back to the moral argument, wherein the existence of objective morality counts as evidence for the existence of God (as the ultimate grounding of that morality). They then show that this results in an ironic turnabout wherein the claim that evil exists actually counts in favor of God’s existence rather than against it.

Support for subjective morality means surrendering the most rhetorically appealing argument against God:  evil.
– Greg Koukl in Solid Ground, May/June 2014

The problem of evil is perhaps the most difficult issue to address … When people complain that there is evil in the world, they are not simply offering their opinion. They are instead saying that true, objective evil exists. … the existence of true evil necessitates the presence of God as a standard of true virtue.
– J. Warner Wallace in Cold Case Christianity, p 134-135

For this post I want to simply consider the claim that a moral anti-realist is being inconsistent if they assert the problem of evil as evidence against the existence of God.

Let me paint a picture…

David Hume said that “Beauty in things exists merely in the mind which contemplates them”. As far as I can tell, we generally agree that beauty is a subjective judgment. There is no absolute standard of beauty. What one man finds beautiful, another may not.

Suppose a painter has spent a lifetime creating intricate paintings of serene, natural settings filled with mountains, streams, meadows and wildlife. He doesn’t want credit for his work so he submits everything anonymously and is only known to the art world as “Mr. X”. To each piece he attaches a dialog highlighting the aesthetic merits of the painting – the rich hues, the use of light and shadow and, most importantly, the realism. Throughout the course of his life he has closed every dialog with the phrase “Nothing is more beautiful than reality”. All the while, this same painter has been a vociferous critic of abstract art. He would regularly publish editorials bashing the modern art movements as having produced nothing but pointless garbage. To him, these “artists” were simply wasting perfectly good paint. Everybody knew exactly where Mr. X stood, though they didn’t know who he was.

abstractThen one morning a curator arrives at his museum to find a painting on his doorstep. The painting is little more than a few haphazard lines and a couple splatters of paint. Attached to the painting is a note that simply says “My most beautiful work. – Mr. X”. The curator sets it aside as a curiosity. As the years go by Mr. X continues submitting more of his traditional landscape paintings and more editorials about the irreverence of abstract art. There is no hint that anything has changed.

So what do we make of the curious abstract painting and note attributed to Mr. X? Was it a joke? Did it actually come from somebody else? No matter what the answer is, there is a simple contradiction: either all the other paintings betray Mr. X’s true perspective, or the note on the abstract painting is wrong. The question of “objective beauty” is irrelevant.

Back to the problem of evil

Hopefully its clear how this analogy relates back to the moral anti-realist’s use of the problem of evil, but I’ll dissect it anyway. God is Mr. X, realist art equates to the moral good and abstract art equates to the moral evil. As with Mr. X, repeated exposure to God’s viewpoint, via divine revelation and theology, have shown us what he considers to be good and evil. God’s morality has been spelled out for us directly (e.g., the ten commandments, sermon on the mount), in rules of thumb (e.g., do unto others as you would have them do unto you) and by the moral law that he has written on the hearts of men. We get it. We have a pretty clear picture of what it is that God considers morally good and morally evil and for the most part we share that perspective and are able to identify moral judgments that we know will align with God’s morality.

So what do we make of the presence of evil in God’s dominion? As far as I can tell, moral realism doesn’t even come into play. The problem of evil is not exposing a contradiction between God’s dominion and an objective morality; it is exposing a contradiction between God’s dominion and his revealed character and attributes. Just as with the mysterious painting, the question of objectivity is irrelevant. We perceive evil in accordance with God’s definition of evil, which is generally shared with our definition of evil, and we wonder why he doesn’t stop it.

If moral realism is an unnecessary addition to the problem of evil then the apologists’ turnabout falls flat. So does the problem of evil count against the existence of God? Well, clearly one solution is that he simply isn’t there but that isn’t the only option. You could also accept that either ‘true morality’ feels uncomfortably immoral or that God is not perfect. No matter what, some concession appears to be necessary. The problem of evil is not some half-wit gimmick that can be turned on its head to defend the existence of God. It is a real problem that cannot be ignored.
