How (Not) To Read Sextus Empiricus

Roger here again.

Since I’ve treated the topic here before, once or twice — though never in the detail required to satisfy certain skeptics of skepticism — I thought I’d let folks know that a paper of mine, on Pyrrhonian skepticism, has come out in the latest issue of Ancient Philosophy.

It’s behind a pay-wall, unfortunately, and I can’t simply post it here.  Anyone affiliated with a university should have free access to it, though.

The paper was originally written in 2012, soon after I wrote the two TPB posts linked to above.  It was accepted for publication that summer, but is only now appearing — which is just as well, as far as I’m concerned, since I kept making changes to it through last fall, when it was finally type-set.

At any rate, I’d be happy to chat about it if folks are interested.

Neuroscience vs. Philosophy

Since Scott’s on vacation, I thought I’d post a video I stumbled on.

Thoughts?

The Philosopher, the Drunk, and the Lamppost

A crucial variable of interest is the accuracy of metacognitive reports with respect to their object-level targets: in other words, how well do we know our own minds? We now understand metacognition to be under segregated neural control, a conclusion that might have surprised Comte, and one that runs counter to an intuition that we have veridical access to the accuracy of our perceptions, memories and decisions. A detailed, and eventually mechanistic, account of metacognition at the neural level is a necessary first step to understanding the failures of metacognition that occur following brain damage and psychiatric disorder. Stephen M. Fleming and Raymond J. Dolan, “The neural basis of metacognitive ability,” Phil. Trans. R. Soc. B (2012) 367, 1338–1349doi:10.1098/rstb.2011.0417

As well as the degree to which we should accept the deliverances of philosophical reflection.

Philosophical reflection is a cultural achievement, an exaptation of pre-existing cognitive capacities. It is entirely possible that philosophical reflection, as an exaptation of pre-existing biocognitive capacities, suffers any number of cognitive short-circuits. And this could very well explain why philosophy suffers the perennial problems it does.

In other words, the empirical possibility of Blind Brain Theory cannot be doubted—no matter how disquieting its consequences seem to be. What I would like to assess here is the probability of the account being empirically substantiated.

The thesis is that traditional philosophical problem-solving continually runs afoul illusions falling out of metacognitive neglect. The idea is that intentional philosophy has been the butt of the old joke about the police officer who stops to help a drunk searching for his keys beneath a lamppost. The punch-line, of course, is that even though the drunk lost his keys in the parking lot, he’s searching beneath the lamppost because that’s the only place he can see. The twist for the philosopher lies in the way neglect consigns the parking lot—the drunk’s whole world in fact—to oblivion, generating the illusion that the light and the lamppost comprise an independent order of existence. For the philosopher, the keys to understanding what we are essentially can be found nowhere else because they exhaust everything that is within that order. Of course the keys that this or that philosopher claims to have found take wildly different forms—they all but shout profound theoretical underdetermination—but this seems to trouble only the skeptical spoil-sports.

Now I personally think the skeptics have always possessed far and away the better position, but since they could only articulate their critiques in the same speculative idiom as philosophy, they have been every bit as easy to ignore as philosophers. But times, I hope to show, have changed—dramatically so. Intentional philosophy is simply another family of prescientific discourses. Now that science has firmly established itself within its traditional domains, we should expect it to be progressively delegitimized the way all prescientific discourses have delegitimized.

To begin with, it is simply an empirical fact that philosophical reflection on the nature of human cognition suffers massive neglect. To be honest, I sometimes find myself amazed that I even need to make this argument to people. Our blindness to our own cognitive makeup is the whole reason we require cognitive science in the first place. Every single fact that the sciences of cognition and the brain have discovered is another fact that philosophical reflection is all but blind to, another ‘dreaded unknown unknown’ that has always structured our cognitive activity without our knowledge.

As Keith Frankish and Jonathan Evans write:

The idea that we have ‘two minds’ only one of which corresponds to personal, volitional cognition, has also wide implications beyond cognitive science. The fact that much of our thought and behaviour is controlled by automatic, subpersonal, and inaccessible cognitive processes challenges our most fundamental and cherished notions about personal and legal responsibility. This has major ramifications for social sciences such as economics, sociology, and social policy. As implied by some contemporary researchers … dual process theory also has enormous implications for educational theory and practice. As the theory becomes better understood and more widely disseminated, its implications for many aspects of society and academia will need to be thoroughly explored. In terms of its wider significance, the story of dual-process theorizing is just beginning.  “The Duality of Mind: An Historical Perspective, In Two Minds: Dual Processes and Beyond, 25

We are standing on the cusp of a revolution in self-understanding unlike any in human history. As they note, the process of digesting the implications of these discoveries is just getting underway—news of the revolution has just hit the streets of capital, and the provinces will likely be a long time in hearing it. As a result, the old ways still enjoy what might be called the ‘Only-game-in-town Effect,’ but not for very long.

The deliverances of theoretical metacognition just cannot be trusted. This is simply an empirical fact. Stanslaus Dehaene even goes so far as to state it as a law: “We constantly overestimate our awareness—even when we are aware of glaring gaps in our awareness” (Consciousness and the Brain, 79).

As I mentioned, I think this is a deathblow, but philosophers have devised a number of cunning ways to immunize themselves from this fact—philosophy is the art of rationalization, after all! If the brain (for some pretty obvious reasons) is horrible at metacognizing brain functions, then one need only insist that something more than the brain is at work. Since souls will no longer do, the philosopher switches to functions, but not any old functions. The fact that the functions of a system look different depending on the grain of investigation is no surprise: of course neurocellular level descriptions will differ from neural-network level descriptions. The intentional philosopher, however, wants to argue for a special, emergent order of intentional functions, one that happens to correspond to the deliverances of philosophical reflection. Aside from this happy correspondence, what makes these special functions so special is their incompatibility with biomechanical functions—an incompatibility so profound that biomechanical explanation renders them all but unintelligible.

Call this the ‘apples and oranges’ strategy. Now I think the sheer convenience of this view should set off alarm bells: If the science of a domain contradicts the findings of philosophical reflection, then that science must be exploring a different domain. But the picture is far more complicated, of course. One does not overthrow more than two thousand years of (apparent) self-understanding on the back of two decades of scientific research. And even absent this institutional sanction, there remains something profoundly compelling about the intentional deliverances of philosophical reflection, despite all the manifest problems. The intentionalist need only bid you to theoretically reflect, and lo, there are the oranges… Something has to explain them!

In other words, pointing out the mountain of unknown unknowns revealed by cognitive science is simply not enough to decisively undermine the conceits of intentional philosophy. I think it should be, but then I think the ancient skeptics had the better of things from the outset. What we really need, if we want to put an end to this vast squandering of intellectual resources, is to explain the oranges. So long as oranges exist, some kind of abductive case can be made for intentional philosophy. Doing this requires we take a closer look at what cognitive science can teach us about philosophical reflection and its capacity to generate self-understanding.

The fact is the intentionalist is in something of a dilemma. Their functions, they admit, are naturalistically inscrutable. Since they can’t abide dualism, they need their functions to be natural (or whatever it is the sciences are conjuring miracles out of) somehow, so whatever functions they posit, say as one realized in the scorekeeping attitudes of communities, they have to track brain function somehow. This responsibility to cognitive scientific finding regarding their object is matched by a responsibility to cognitive scientific finding regarding their cognitive capacity. Oranges or no oranges, both their domain and their capacity to cognize that domain answer to what cognitive science ultimately reveals. Some kind of emergent order has to be discovered within the order of nature, and we have to have to somehow possess the capacity to reliably metacognize that emergent order. Given what we already know, I think a strong case can be made that this latter, at least, is almost certainly impossible.

Consider Dehaene’s Global Neuronal Workspace Theory of Consciousness (GNW). On his account, at any given moment the information available for conscious report has been selected from parallel swarms of nonconscious processes, stabilized, and broadcast across the brain for consumption by other swarms of other nonconscious processes. As Dehaene writes:

The brain must contain a ‘router’ that allows it to flexibly broadcast information to and from its internal routines. This seems to be a major function of consciousness: to collect the information from various processors, synthesize it, and then broadcast the result—a conscious symbol—to other, arbitrarily selected processors. These processors, in turn, apply their unconscious skills to this symbol, and the entire process may repeat a number of times. The outcome is a hybrid serial-parallel machine, in which stages of massively parallel computation are interleaved with a serial stage of conscious decision making and information routing. Consciousness and the Brain, 105

Whatever philosophical reflection amounts to, insofar as it involves conscious report it involves this ‘hybrid serial-parallel machine’ described by Dehaene and his colleagues, a model which is entirely consistent with the ‘adaptive unconscious’ (See Tim Wilson’s A Stranger to Ourselves for a somewhat dated, yet still excellent overview) described in cognitive psychology. Whatever a philosopher can say regarding ‘intentional functions’ must in some way depend on the deliverances of this system.

One of the key claims of the theory, confirmed via a number of different experimental paradigms, is that access (or promotion) to the GNW is all or nothing. The insight is old: psychologists have long studied what is known as the ‘psychological refractory period,’ the way attending to one task tends to blot out or severely impair our ability to perform other tasks simultaneously. But recent research is revealing more of the radical ‘cortical bottleneck’ that marks the boundary between the massively parallel processing of multiple precepts (or interpretations thereof) and the serial stage of conscious cognition. [Marti, S., et al., A shared cortical bottleneck underlying Attentional Blink and Psychological Refractory Period, NeuroImage (2011), doi:10.1016/j.neuroimage.2011.09.063]

This is important because it means that the deliverances the intentional philosopher depend on when reflecting on problems involving intentionality or ‘experience’ more generally are limited to what makes the ‘conscious access cut.’ You could say the situation is actually far worse, since conscious deliberation on conscious phenomena requires the philosopher use the very apparatus they’re attempting to solve. In a sense they’re not only wagering that the information they require actually reaches consciousness in the first place, but that it can be recalled for subsequent conscious deliberation. The same way the scientist cannot incorporate information that doesn’t, either via direct observation or indirect observation via instrumentation, find its way to conscious awareness, the philosopher likewise cannot hazard ‘educated’ guesses regarding information that does not somehow make the conscious access cut, only twice over. In a sense, they’re peering at the remaindered deliverances of a serial straw through a serial straw–one that appears as wide as the sky for neglect! So there is a very real question of whether philosophical reflection, an artifactual form of deliberative cognition, has anything approaching access to the information it needs to solve the kinds of problems it purports to solve. Given the role that information scarcity plays in theoretical underdetermination, the perpetually underdetermined theories posed by intentional philosophers strongly suggest that the answer is no.

But if the science suggests that philosophical reflection may not have access to enough information to answer the questions in its bailiwick, it also raises real questions of whether it has access to the right kind of information. Recent research has focussed on attempting to isolate the mechanisms in the brain responsible for mediating metacognition. The findings seem to be converging on the rostrolateral prefrontal cortex (rlPFC) as playing a pivotal role in the metacognitive accuracy of retrospective reports. As Fleming and Dolan write:

A role for rlPFC in metacognition is consistent with its anatomical position at the top of the cognitive hierarchy, receiving information from other prefrontal cortical regions, cingulate and anterior temporal cortex. Further, compared with non-human primates, rlPFC has a sparser spatial organization that may support greater interconnectivity. The contribution of rlPFC to metacognitive commentary may be to represent task uncertainty in a format suitable for communication to others, consistent with activation here being associated with evaluating self-generated information, and attention to internal representations. Such a conclusion is supported by recent evidence from structural brain imaging that ‘reality monitoring’ and metacognitive accuracy share a common neural substrate in anterior PFC.  Italics added, “The neural basis of metacognitive ability,” Phil. Trans. R. Soc. B (2012) 367, 1343. doi:10.1098/rstb.2011.0417

As far as I can tell, the rlPFC is perhaps the best candidate we presently have for something like a ‘philosopher module’ [See Badre, et al. "Frontal cortex and the discovery of abstract action rules." Neuron (2010) 66:315–326.] though the functional organization of the PFC more generally remains a mystery. [Kalina Christoff’s site and Steve Fleming’s site are great places to track research developments in this area of cognitive neuroscience] It primarily seems to be engaged by abstract relational and semantic tasks, and plays some kind of role mediating verbal and spatial information. Mapping evidence also shows that its patterns of communication to other brain regions varies as tasks vary; in particular, it seems to engage regions thought to involve visuospatial and semantic processes. [Wendelken et al., “Rostrolateral Prefrontal Cortex: Domain-General or Domain-Sensitive?” Human Brain Mapping, 000:00-00, 2011 1-12.]

Cognitive neuroscience is nowhere close to any decisive picture of abstract metacognition, but hopefully the philosophical moral of the research should be clear: whatever theoretical metacognition is, it is neurobiological. And this is just to say that the nature of philosophical reflection—in the form of say, ‘making things explicit,’ or what have you—is not something that philosophical reflection on ‘conscious experience’ can solve! Dehaene’s law applies as much to metacognition as to any other metacognitive process—as we should expect, given the cortical bottleneck and what we know of the rlPFC. Information is promoted for stabilization and broadcast from nonconscious parallel swarms to be consumed by nonconscious parallel swarms, which include the rlPFC, which in turn somehow informs further stabilizations and broadcasts. What we presently ‘experience,’ the well from which our intentional claims are drawn, somehow comprises the serial ‘stabilization and broadcast’ portion of this process—and nothing else.

The rlPFC is an evolutionary artifact, something our ancestors developed over generations of practical problem-solving. It is part and parcel of the most complicated (not to mention expensive) organ known. Assume, for the moment, that the rlPFC is the place where the magic happens, the part of the ruminating philosopher’s brain where ‘accurate intuitions’ of the ‘nature of mind and thought’ arise allowing for verbal report. (The situation is without a doubt far more complicated, but since complication is precisely the problem the philosopher faces, this example actually does them a favour). There’s no way the rlPFC could assist in accurately cognizing its own function—another rlPFC would be required to do that, requiring a third rlPFC, and so on and so on. In fact, there’s no way the brain could directly cognize its own activities in any high-dimensionally accurate way. What the rlPFC does instead—obviously one would think—is process information for behaviour. It has to earn its keep after all! Given this, one should expect that it is adapted to process information that is itself adapted to solve the kinds of behaviourally related problems faced by our ancestors, that it consists of ad hoc structures processing ad hoc information.

Philosophy is quite obviously an exaptation of the capacities possessed by the rlPFC (and the systems of which it is part), the learned application of metacognitive capacities originally adapted to solve practical behavioural problems to theoretical problems possessing radically different requirements—such as accuracy, the ability to not simply use a cognitive tool, but to be able to reliably determine what that cognitive tool is.

Even granting the intentionalist their spooky functional order, are we to suppose, given everything considered, that we just happened to have evolved the capacity to accurately intuit this elusive functional order? Seems a stretch. The far more plausible answer is that this exaptation, relying as it does on scarce and specialized information, was doomed from the outset to get far more things wrong than right (as the ancient skeptics insisted!). The far more plausible answer is that our metacognitive capacity is as radically heuristic as cognitive science suggests. Think of the scholastic jungle that is analytic and continental philosophy. Or think of the yawning legitimacy gap between mathematics (exaptation gone right) versus the philosophy of mathematics (exaptation gone wrong). The oh so familiar criticisms of philosophy, that it is impractical, disconnected from reality, incapable of arbitrating its controversies—in short, that it does not decisively solve—are precisely the kinds of problems we might expect, were philosophical reflection an artifact of an exaptation gone wrong.

On my account it is wildly implausible that any design paradigm like evolution could deliver the kind of cognition intentionalism requires. Evolution solves difficult problems heuristically: opportunistic fixes are gradually sculpted by various contingent frequencies in its environment, which in our case, were thoroughly social. Since the brain is the most difficult problem any brain could possibly face, we can assume the heuristics our brain relies on to cognize other brains will be specialized, and that the heuristics it uses to cognize itself will be even more specialized still. Part of this specialization will involve the ability to solve problems absent any causal information: there is simply no way the human brain can cognize itself the way it cognizes its natural environment. Is it really any surprise that causal information would scuttle problem-solving adapted to solve in its absence? And given our blindness to the heuristic nature of the systems involved, is it any surprise that we would be confounded by this incompatibility for as long as we have?

The problem, of course, it that it so doesn’t seem that way. I was a Heideggerean once. I was also a Wittgensteinian. I’ve spent months parsing Husserl’s torturous attempts to discipline philosophical reflection. That version of myself would have scoffed at these kinds of criticisms. ‘Scientism!’ would have been my first cry; ‘Performative contradiction!’ my second. I was so certain of the intrinsic intentionality of human things that the kind of argument I’m making here would have struck me as self-evident nonsense. ‘Not only are these intentional oranges real,’ I would have argued, ‘they are the only thing that makes scientific apples possible.’

It’s not enough to show the intentionalist philosopher that, by the light of cognitive science, it’s more than likely their oranges do not exist. Dialectically, at least, one needs to explain how, intuitively, it could seem so obvious that they do exist. Why do the philosopher’s ‘feelings of knowing,’ as murky and inexplicable as they are, have the capacity to convince them of anything, let alone monumental speculative systems?

As it turns out, cognitive psychology has already begun interrogating the general mechanism that is likely responsible, and the curious ways it impacts our retrospective assessments: neglect. In Thinking, Fast and Slow, Daniel Kahneman cites the difficulty we have distinguishing experience from memory as the reason why we retrospectively underrate our suffering in a variety of contexts. Given the same painful medical procedure, one would expect an individual suffering for twenty minutes to report a far greater amount than an individual suffering for half that time or less. Such is not the case. As it turns out duration has “no effect whatsoever on the ratings of total pain” (380). Retrospective assessments, rather, seem determined by the average of the pain’s peak and its coda. Absent intellectual effort, you could say the default is to remove the band-aid slowly.

Far from being academic, this ‘duration neglect,’ as Kahneman calls it, places the therapist in something of a bind. What should the physician’s goal be? The reduction of the pain actually experienced, or the reduction of the pain remembered. Kahneman provocatively frames the problem as a question of choosing between selves, the ‘experiencing self’ that actually suffers the pain and the ‘remembering self’ that walks out of the clinic. Which ‘self’ should the therapist serve? Kahneman sides with the latter. “Memories,” he writes, “are all we get to keep from our experience of living, and the only perspective that we can adopt as we think about our lives is therefore that of the remembering self” (381). If the drunk has no recollection of the parking lot, then as far as his decision making is concerned, the parking lot simply does not exist. Kahneman writes:

Confusing experience with the memory of it is a compelling cognitive illusion—and it is the substitution that makes us believe a past experience can be ruined. The experiencing self does not have a voice. The remembering self is sometimes wrong, but it is the one that keeps score and governs what we learn from living, and it is the one that makes decisions. What we learn from the past is to maximize the qualities of our future memories, not necessarily of our future experience. This is the tyranny of the remembering self. 381

Could it be that this is what philosophers are doing? Could they, in the course of defining and arranging their oranges, simply be confusing their memory of experience with experience itself? So in the case of duration neglect, information regarding the duration of suffering makes no difference in the subject’s decision making because that information is nowhere to be found. Given the ubiquity of similar effects, Kahneman generalizes the insight into what he calls WYSIATI, or What-You-See-Is-All-There-Is:

An essential design feature of the associative machine is that it represents only activated ideas. Information that is not retrieved (even unconsciously) from memory might as well not exist. [Our nonconscious cognitive system] excels at constructing the best possible story that incorporates ideas currently activated, but it does not (cannot) allow for information it does not have. 85

Kahneman’s WYSIATI, you could say, provides a way to explain Dehaene’s Law regarding the chronic overestimation of awareness. The cortical bottleneck renders conscious access captive to the facts as they are given. If information regarding things like the duration of suffering in an experimental context isn’t available, then that information simply makes no difference for subsequent behaviour. Likewise, if information regarding the reliability of an intuition or ‘feeling of knowing’ (aptly abbreviated as ‘FOK’ in the literature!) isn’t available, then that information simply makes no difference—at all.

Thus the illusion of what I’ve been calling cognitive sufficiency these past few years. Kahneman lavishes the reader in Thinking, Fast and Slow with example after example of how subjects perennially confuse the information they do have with all the information they need:

You cannot help dealing with the limited information you have as if it were all there is to know. You build the best possible story from the information available to you, and if it is a good story, you believe it. Paradoxically, it is easier to construct a coherent story when you know little, when there are fewer pieces to fit into the puzzle. Our comforting conviction that the world makes sense rests on a secure foundation: our almost unlimited ability to ignore our ignorance. 201

You could say what his research has isolated the cognitive conceit that lies at the heart of Plato’s cave: absent information regarding the low-dimensionality of the information they have available, shadows become everything. Like the parking lot, the cave, the chains, the fire, even the possibility of looking from side-to-side simply do not exist for the captives.

As the WYSIATI rule implies, neither the quantity nor the quality of the evidence counts for much in subjective confidence. The confidence that individuals have in their beliefs depends mostly on the quality of the story they can tell about what they see, even if they see little. We often fail to allow for the possibility that evidence that should be critical to our judgment is missing—what we see is all there is. Furthermore, our associative system tends to settle on a coherent pattern of activation and suppresses doubt and ambiguity. 87-88

Could the whole of intentional philosophy amount to varieties of story-telling, ‘theory-narratives’ that are compelling to their authors precisely to the degree they are underdetermined? The problem as Kahneman outlines it is twofold. For one, “[t]he human mind does not deal well with nonevents” (200) simply because unavailable information is information that makes no difference. This is why deception, or any instance of controlling information availability, allows us to manipulate our fellow drunks so easily. For another, “[c]onfidence is a feeling, which reflects the coherence of the information and the cognitive ease of processing it,” and “not a reasoned evaluation of the probability that this judgment is correct” (212). So all that time I was reading Heidegger nodding, certain that I was getting close to finding the key, I was simply confirming parochial assumptions. Once I had bought in, coherence was automatic, and the inferences came easy. Heidegger had to be right—the key had to be beneath his lamppost—simply because it all made so much remembered sense ‘upon reflection.’

Could it really be as simple as this? Now given philosophers’ continued insistence on making claims despite their manifest institutional incapacity to decisively arbitrate any of them, neglect is certainly a plausible possibility. But the fact is this is precisely the kind of problem we should expect given that philosophical reflection is an exaptation of pre-existing cognitive capacities.

Why? Because what researchers term ‘error awareness,’ like every other human cognitive capacity, does not come cheap. To be sure, the evolutionary premium on error-detection is high to the extent that adaptive behaviour is impossible otherwise. It is part and parcel of cognition. But philosophical reflection is, once again, an exaptation of pre-existing metacognitive capacities, a form of problem-solving that has no evolutionary precedent. Research has shown that metacognitive error-awareness is often problematic even when applied to problems, such as assessing memory accuracy or behavioural competence in retrospect, that it has likely evolved to solve. [See, Wessel, “Error awareness and the error-related negativity: evaluating the first decade of evidence,” Front Hum Neurosci. 2012; 6: 88. doi: 10.3389/fnhum.2012.00088, for a GNW related review] So if conscious error-awareness is hit or miss regarding adaptive activities, we should expect that, barring some cosmic stroke of evolutionary good fortune, it pretty much eludes philosophical reflection altogether. Is it really surprising that the only erroneous intuitions philosophers seem to detect with any regularity are those belonging to their peers?

We’re used to thinking of deficits in self-awareness in pathological terms, as something pertaining to brain trauma. But the picture emerging from cognitive science is positively filled with instances of non-pathological neglect, metacognitive deficits that exist by virtue of our constitution. The same way researchers can game the heuristic components of vision to generate any number of different visual illusions, experimentalists are learning how to game the heuristic components of cognition to isolate any number of cognitive illusions, ways in which our problem-solving goes awry without the least conscious awareness. In each of these cases, neglect plays a central role in explaining the behaviour of the subjects under scrutiny, the same way clinicians use neglect to explain the behaviour of their impaired patients.

Pathological neglect strikes us as so catastrophically consequential in clinical settings simply because of the behavioural aberrations of those suffering it. Not only does it make a profoundly visible difference, it makes a difference that we can only understand mechanistically. It quite literally knocks individuals from the problem-ecology belonging to socio-cognition into the problem-ecologies belonging to natural cognition. Socio-cognition, as radically heuristic, leans heavily on access to certain environmental information to function properly. Pathological neglect denies us that information.

Non-pathological neglect, on the other hand, completely eludes us because, insofar as we share the same neurophysiology, we share the same ‘neglect structure.’ The neglect suffered is both collective and adaptive. As a result, we only glimpse it here and there, and are more cued to resolve the problems it generates than ponder the deficits in self-awareness responsible. We require elaborate experimental contexts to draw it into sharp focus.

All Blind Brain Theory does is provide a general theoretical framework for these disparate findings, one that can be extended to a great number of traditional philosophical problems—including the holy grail, the naturalization of intentionality. As of yet, the possibility of such a framework remains at most an inkling to those at the forefront of the field (something that only speculative fiction authors dare consider!) but it is a growing one. Non-pathological neglect is not only a fact, it is ubiquitous. Conceptualized the proper way, it possesses a very parsimonious means of dispatching with a great number of ancient and new conundrums…

At some point, I think all these mad ramblings will seem painfully obvious, and the thought of going back to tackling issues of cognition neglecting neglect will seem all but unimaginable. But for the nonce, it remains very difficult to see—it is neglect we’re talking about, after-all!—and the various researchers struggling with its implications lie so far apart in terms of expertise and idiom that none can see the larger landscape.

And what is this larger landscape? If you swivel human cognitive capacity across the continuum of human interrogation you find a drastic plunge in the dimensionality and an according spike in the specialization of the information we can access for the purposes of theorization as soon as brains are involved. Metacognitive neglect means that things like ‘person’ or ‘rule’ or what have you seem as real as anything else in the world when you ponder them, but in point of fact, we have only our intuitions to go on, the most meagre deliverances lacking provenance or criteria. And this is precisely what we should expect given the rank inability of the human brain to cognize itself or others in the high-dimensional manner it cognizes its environments.

This is the picture that traditional, intentional philosophy, if it is to maintain any shred of cognitive legitimacy moving forward, must somehow accommodate. Since I see traditional philosophy as largely an unwitting artifact of this landscape, I think such an accommodation will result in dissolution, the realization that philosophy has largely been a painting class for the blind. Some useful works have been produced here and there to be sure, but not for any reason the artists responsible suppose. So I would like to leave you with a suggestive parallel, a way to compare the philosopher with the sufferer of Anton’s Syndrome, the notorious form of anosognosia that leaves blind patients completely convinced they can see. So consider:

First, the patient is completely blind secondary to cortical damage in the occipital regionsof the brain. Second, these lesions are bilateral. Third, the patient is not only unaware of her blindness; she rejects any objective evidence of her blindness. Fourth, the patient offers plausible, but at times confabulatory responses to explain away any possible evidence of her failure to see (e.g., “The room is dark,” or “I don’t have my glasses,therefore how can I see?”). Fifth, the patient has an apparent lack of concern (or anosodiaphoria) over her neurological condition. Prigatano and Wolf, “Anton’s Syndrome and Unawareness of Partial or Complete Blindness,” The Study of Anosognosia, 456.

And compare to:

First, the philosopher is metacognitively blind secondary to various developmental and structural constraints. Second, the philosopher is not aware of his metacognitive blindness, and is prone to reject objective evidence of it. Third, the philosopher offers plausible, but at times confabulatory responses to explain away evidence of his metacognitive incapacity. And fourth, the philosopher often exhibits an apparent lack of concern for his less than ideal neurological constitution.

An Empty Post on Empty Ideas

Discontinuity Thesis: A ‘Birds of a Feather’ Argument Against Intentionalism

A hallmark of intentional phenomena is what might be called ‘discontinuity,’ the idea that the intentional somehow stands outside the contingent natural order, that it possesses some as-yet-occult ‘orthogonal efficacy.’ Here’s how some prominent intentionalists characterize it:

“Scholars who study intentional phenomena generally tend to consider them as processes and relationships that can be characterized irrespective of any physical objects, material changes, or motive forces. But this is exactly what poses a fundamental problem for the natural sciences. Scientific explanation requires that in order to have causal consequences, something must be susceptible of being involved in material and energetic interactions with other physical objects and forces.” Terrence Deacon, Incomplete Nature, 28

“Exactly how are consciousness and subjective experience related to brain and body? It is one thing to be able to establish correlations between consciousness and brain activity; it is another thing to have an account that explains exactly how certain biological processes generate and realize consciousness and subjectivity. At the present time, we not only lack such an account, but are also unsure about the form it would need to have in order to bridge the conceptual and epistemological gap between life and mind as objects of scientific investigation and life and mind as we subjectively experience them.” Evan Thompson, Mind in Life, x

“Norms (in the sense of normative statuses) are not objects in the causal order. Natural science, eschewing categories of social practice, will never run across commitments in its cataloguing of the furniture of the world; they are not by themselves causally efficacious—no more than strikes or outs are in baseball. Nonetheless, according to the account presented here, there are norms, and their existence is neither supernatural nor mysterious. Normative statuses are domesticated by being understood in terms of normative attitudes, which are in the causal order.” Robert Brandom, Making It Explicit, 626

What I would like to do is run through a number of different discontinuities you find in various intentional phenomena as a means of raising the question: What are the chances? What’s worth noting is how continuous these alleged phenomena are with each other, not simply in terms of their low-dimensionality and natural discontinuity, but in terms of mutual conceptual dependence as well. I made a distinction between ‘ontological’ and ‘functional’ exemptions from the natural even though I regard them as differences of degree because of the way it maps stark distinctions in the different kinds of commitments you find among various parties of believers. And ‘low-dimensionality’ simply refers to the scarcity of the information intentional phenomena give us to work with—whatever finds its way into the ‘philosopher’s lab,’ basically.

So with regard to all of the following, my question is simply, are these not birds of a feather? If not, then what distinguishes them? Why are low-dimensionality and supernaturalism fatal only for some and not others?

The big question here, from a naturalistic standpoint, is whether all of these characteristics are homologous or merely analogous. Are the similarities ontogenetic, the expression of some shared ‘deep structure,’ or merely coincidental? For me this has to be what I think is one of the most significant questions that never get’s asked in cognitive science. Why? Because everybody has their own way of divvying up the intentional pie (including interpretavists like Dennett). Some of these items are good, and some of them are bad, depending on whom you talk to. If these phenomena were merely analogous, then this division need not be problematic—we’re just talking fish and whales. But if these phenomena are homologous—if we’re talking whales and whales—then the kinds of discursive barricades various theorists erect to shelter their ‘good’ intentional phenomena from ‘bad’ intentional phenomena need to be powerfully motivated.

Pointing out the apparent functionality of certain phenomena versus others simply will not do. The fact that these phenomena discharge some kind of function somehow seems pretty clear. It seems to be the case that God anchors the solution to any number of social problems—that even Souls discharge some function in certain, specialized problem-ecologies. The same can be said of Truth, Rule/Norm, Agency—every item on this list, in fact.

And this is precisely what one might expect given a purely biomechanical, heuristic interpretation of these terms as well (with the added advantage of being able to explain why our phenomenological inheritance finds itself mired in the kinds of problems it does). None of these need count as anything resembling what our phenomenological tradition claims to explain the kinds of behaviour that accompanies them. God doesn’t need to be ‘real’ to explain church-going, no more than Rules/Norms do to explain rule-following. Meanwhile, the growing mountain of cognitive scientific discovery looms large: cognitive functions generally run ulterior to what we can metacognize for report. Time and again, in context after context, empirical research reveals that human cognition is simply not what we think it is. As ‘Dehaene’s Law’ states, “We constantly overestimate our awareness—even when we are aware of glaring gaps in our awareness” (Consciousness and the Brain, 79). Perhaps this is simply what intentionality amounts to: a congenital ‘overestimation of awareness,’ a kind of WYSIATI or ‘what-you-see-is-all-there-is’ illusion. Perhaps anthropic, low-dimensional, functionally exempt from natural continuity, inscrutable in terms of natural continuity, source of perennial controversy, and possesses inexplicable efficacy are all expressions of various kinds of neglect. Perhaps it isn’t just a coincidence that we are entirely blind to our neuromechanical embodiment and that we suffer this compelling sense that we are more than merely neuromechanical.

How could we cognize the astronomical causal complexities of cognition? What evolutionary purpose would it serve?

What impact does our systematic neglect of those capacities have on philosophical reflection?

Does anyone really think the answer is going to be ‘minimal to nonexistent’?

Father’s Day, 2025

Sunday, June 15th, 2025, New York BureauWal-Mart stock has enjoyed a recent surge in both algorithmic and human markets today, given greater than expected profits attributed to the company’s new visual fixation tracking systems. This novel system not only allows the retail giant to track the eye-movements of every customer in the store (a data collection system that promises immense downstream rewards in its own right), it also provides the informational underpinnings for a real-time version of what the industry has come to call the ‘Ping Market.’

You know those little twinkling lights on the shelves that make your child crow with delight? Well each flicker is what is called a ‘ping,’ a peripheral stimulus designed to alert the attentional systems of the human brain, and so trigger what is called ‘gaze fixation,’ which in turn is a powerful predictor of consumer choice. Historically (if three years count as such!), retailers have auctioned pings in bulk on the basis of statistical data garnered over time. Wal-Mart’s new system, however, allows its suppliers to quite literally bid for customers as they walk down the aisle, using online data tracking customer’s saccades and fixations to calculate the probable effectiveness of individual pings (and, unfortunately, those endlessly annoying ‘shelfies’). Customer tracking is anonymized by law, of course, but the company reports that its most recent ’15 for 15’ promotion has managed to boost its privacy opt-out level to just over 83%. An envious number to be sure.

‘‘Go fish’ has long been a term of frustration in retail,’ says the project director, Dr. Howard Singh. ‘With [their new ping system] the metaphor has become literal, and Wal-Mart, always the ocean of the industry, has transformed itself into an angler’s delight!’

For those who pay the fee, of course.

Enactivist Re-enactment

Adam Robberts has tidied up and reposted a debate he and I have been having on enactivism and Blind Brain Theory over at his Knowledge Ecology site. Dissenters are welcome to weigh in over here, there, or at any one of the several sites that have reblogged our exchange. All the lapses in decorum and diction are entirely my own.

By dint of sheer coincidence, Eric Schwitzgebel has included the Bonjour post immediately below in his roundup of the Philosopher’s Carnival – Zombie Mary should be pleased! God and Jesus, not so much.

As for the novel, still no word on pub dates, but I did spend the past two days with my friend Madness going through the manuscript, so if you’re curious as to his impressions, appraisals, by all means visit the SECOND APOCALYPSE FORUM and plague him with questions…
