An unconscious naked man (1912), Richard Tennant Cooper
Cognitive scientist Donald Hoffman has recently been getting popular attention for a theory that holds consciousness as fundamental—that is, “…not as something derivative or emergent from a prior physical world”1, which he supports with a novel account of the relation between objects and perception (a relation that he argues, on evolutionary grounds, is nonveridical, i.e., perception does not faithfully represent or reconstruct objective/external reality); Hoffman’s theory also requires a novel account of the relation between the brain and consciousness. I’m not going to get into the theory here, though I find it thought-provoking.2 Instead, I’d like to pivot off a nice expression he often employs about our prospects for understanding consciousness (something we seem yet very far from accomplishing):
“Some experts think that we can’t solve this problem because we lack the necessary concepts and intelligence. We don’t expect monkeys to solve problems in quantum mechanics, and, as it happens, we can’t expect our species to solve this problem either.”3
Unlike Hoffman, I agree with the skeptical experts. Before explaining why, some conceptual grounding. Continue Reading →

I. A Critical Distinction
It’s a common occurrence for someone to be publicly called out for racism, sexism, homophobia, transphobia, or some other mode of X-ism (as I’ll collectively call these and similar -isms/-phobias), only for the accused to earnestly self-defend, “I’m not X-ist! I love X’s! There are X’s among my most cherished friends and family!”
Debates then follow about the person’s status as (an) X-ist. (From here on I’ll use “X-ist” with the understanding that it could be replaced with “an X-ist”; I’ll leave unexplored what I sense to be a significant difference between these phrasings.) These debates often fail to reflect the important distinction between performing an X-ist act and being X-ist. To recognize this distinction is to acknowledge the possibility of there existing an X-ist act without the presence of an X-ist actor. There are further important distinctions to notice; to make sense of these, I propose four dimensions of X-ism: Cognitive, Affective, Behavioral, Dispositional.
My claim is that a person’s activities (or potential activities)1 must span some combination of these dimensions in order for the person to merit the X-ism label—in other words, to be branded as someone who engages so habitually in morally reprehensible activities of the sort we call X-ist, that we are justified in saying that person is X-ist (particularly when these activities defy readily observable evidence; that is, when the agent “should know better”).23Continue Reading →
Ever notice that when a familiar song is playing in another room, you can clearly hear the words, but if unfamiliar, you can’t make out the words?
I’ve experienced something similar with self-recording musicians—especially voice-shy ones—who think they’ve set their vocal loud in a mix, but it’s barely audible to anyone else. This has happened to me with solo instruments as well (oboe parts, vocal harmonies, background guitar melodies, etc.).
Familiarity seems to result in experiencing more than is there, more than is actually making it through the walls and the noise—as if your brain, in order to finish constructing the mental content you (unconsciously) expect to experience, is pulling from memory the building materials your environment is failing to provide.
It turns out we can home in on and experiment with this phenomenon with a fascinating technique called sine-wave speech, which I first learned about it on the (excellent) Brain Science Podcast: Andy Clark on Prediction, Action, and the Embodied Mind (BSP 126; January 28, 2016). Listen to the first 2:15 minutes to hear a sine-wave speech demonstration (and I of course recommend the whole episode, especially if you’re interested in embodied cognition, a rising, and I think very promising, interdisciplinary field occupying philosophers, psychologists, linguists, AI-specialists, and others):
We often refer to the beliefs of groups. We might say we think it’s a lovely day out, or that Americans believe democracy to be the best form of government. To what sorts of phenomena do we refer when speaking this way? In the context of belief, should words such as Americans and we be viewed as shorthand for summing up the individually held beliefs of a group’s members? Or, rather, do such words sometimes correctly refer to a group engaged, as a unified entity, in the collective activity of believing? If the latter is true, then it’s possible for a group to believe that p, while the individuals who constitute that group each believes that not-p. Call this sort of belief, in which a group literally has belief of its own, collective belief (while, for clarity’s sake, I’ll use group belief as a neutral term).
On my view, groups are not capable of collective belief. This distinguishes belief from many other sorts of activities. When Mary sings a C and Larry sings an E, for example, Mary and Larry collectively sing a major third, though neither individually sings a major third. Likewise, they might hug, cook dinner, or make the bed. Belief doesn’t seem to work this way: to correctly say that Mary and Larry believe their house is haunted, both must believe that proposition. Ascriptions to larger groups may afford some leeway in this regard, but still require that most members hold the group belief. Continue Reading →
And now for the intriguing case of Rachel Dolezal, the Spokane, Washington NAACP leader who was born white but identifies and represents herself as black. This was working well for her — she’s been passing as black for years, apparently — until a few days ago, when her biological parents outed her. [Update: She announced her resignation as NAACP chapter president on 6/15/15.]
This controversial story has sparked important, hopefully long-enduring, discussions about the ramifications of race’s status as a social construct. If it is a social construct, some argue (often as a bluff-calling dig at Caitlyn Jenner supporters; more on that below), then Dolezal’s performance as a black woman should be respected as an authentic expression of the space she occupies in society.
But this is wrong. Even if race is a social construct (which it is; to see this: a white woman can have a black baby, but a black woman cannot have a white baby), this doesn’t mean that Dolezal’s self-identification as black must be honored. Society, through its collective activities, determines the conditions of race identification–i.e., creates the (very real) phenomenon to which we refer when we use the word race. She is not society.

I often find myself wondering with fascination about the role experience plays in shaping our conception of the world. Recently, I was inspired to think about repetition in this context. That is, we have a deep sense that there are repeating events. But such a thing must be true only in experience, given that any event is, in some way, distinct from all others. Put another way, any event is only identical to itself. At the same time, repetition often has great significance for us, a significance that seems to touch on something true about the world independent of human experience.
Here are some brief musings on the relation between ‘event repetition,’ experience, and our world-conception. What there is to be learned here, I’m not sure. Yet I find myself drawn to this line of inquiry, and do get a fuzzy sense that there is something to be gained from reflecting on it.* Perhaps a deeper investigation into event repetition — both perceptually experienced and not — could reveal useful tidbits for when dealing with bigger questions, such as those related to cognitive biases, social interaction (e.g., stereotyping), experience of ‘objects’ over time, cyclical brain-states (e.g., meditation, sleep), evolutionary psychology, personalized medicine, sense of self in the context of personal identity over time (more on this below, in Part II), and induction (experiment repeatability).
There are also moral implications to this that, I think, lend support to a particularist notion of morality: any moral event is only identical to itself. So, to know (or understand) that an event is wrong, is to know something about that particular event. This would be distinct from what I take to be a less useful (though still nice to have), general knowledge about broader categories of moral events, which have particular events as members. I’m saving that discussion for another day, however.
[*I began thinking about this topic after being asked to contribute to a newly founded magazine whose first issue was going to be broadly themed on ‘pulse.’ I drafted notes on two occasions, here presented as Parts I and II (neither of which was finalized, because the magazine folded before publication). Part I is a straightforward survey of the subject. Part II, written one morning while bleary-eyed and half-asleep, is stylized as a kind of letter inviting the reader to think of herself or himself as a series of non-identical, though significantly related, events — as a pulse.] Continue Reading →
How many objects are in the above box? I say three (the ‘particles’ named A, B, and C), which makes me a nihilist about composition. The universalist says seven: A, B, C, A+B, A+C, B+C, A+B+C. See Ross & Dorr’s “Composition as a Fiction” for further explanation.
In his impressive book, Material Beings, Peter van Inwagen argues in favor of an organicist theory of composition, in which the only things that count as composites are living organisms. This is to say, then, that mugs, tables, automobiles, stones, and other (non-living) things we usually take to be objects don’t actually exist; instead, the only things that exist are simples (i.e., non-composite, and thus part-less, indivisible particles) and organisms. In this paper, I intend to challenge this line of thinking, and will argue instead in favor of compositional nihilism (a.k.a., ‘mereological nihilism’), a view in which the only things that have objective existence, strictly speaking, are simples. On this view, organisms exist no more than do artifacts, heavenly bodies, or anything else that is not a simple.
I will focus especially on van Inwagen’s foundational claim that at least one composite exists: the self-reflective, thinking human being. This claim arises out of the inconceivability of thinking being a cooperative activity among a non-composite collection of particles — particularly if those particles have a unified experience such that leads to the thought, “I exist.” Before addressing van Inwagen’s position, I will first explain what I mean by ‘compositional nihilism.’ Continue Reading →
One of the most irritating argumentative tactics I can think of is when an interlocutor concocts a metaphor of limited reach, and then, in an ad hoceffort to save face, explodes the metaphor (as I call it) by over-straining it. The result is an elaborate reductio ad absurdum of the interlocutor’s own making.
The best way to defuse this rhetorical device is to call the exploder’s bluff. For instance:
Jack: “Lots of music doesn’t work because it lacks a good solid framework to hold it together. Music is like architecture. You have to construct a sturdy framework, then you can proceed to build the building.”
Margie: “Ok… That’s a nice metaphor, but not all music has to be that way. I mean, music isn’t really like architecture. The physical laws that hold up a building, and thus impose certain restrictions on architects and engineers, don’t apply to music.” Continue Reading →
In his book, Philosophical Explanations, in the chapter“Knowledge and Skepticism,” Robert Nozick endeavors to construct a set of conditions that are jointly sufficient for knowledge. Let’s call this the ‘truth-tracking’ account of knowledge. Truth-tracking is meant to deal with a range of hard epistemological cases, including Gettier-style problems and Brain-in-the-Vat-style skeptical arguments. In this paper, I aim to show that, while Nozick’s truth-tracking account doesn’t succeed as a whole (largely for reasons noted by Saul Kripke), the driving intuition of Nozick’s account may still be relevant – or even necessary – for any good theory of knowledge. I will refer to this driving intuition as ‘Sensitivity.’ What I mean by this term will become clearer as we go along.
PART I: Truth-tracking Explained
Nozick begins his project by taking for granted the usual first two conditions for knowledge: (1) p is true; (2) S believes that p. I’ll take these for granted as well. To these he adds a third condition, the subjunctive conditional: (3) If p weren’t true, S wouldn’t believe that p. We may also express this in Lewisian language as ~p□→~(SBp).[1. Nozick expresses it as: not-p → not-(S believes that p) (page 172).] I will, however, avoid such formalisms, because I want to be semantically clear about what I’m referring to. Nozick also uses ‘possible worlds’ semantics to express (3), though is not committed to such expressions.[2. “I do not mean to endorse any particular possible-world account of subjunctives, nor am I committed to this type of account” (page 174).] I will make use of these. For example, S’s belief should be counterfactually sensitive so that, in the closest worlds where not-p, S wouldn’t mistakenly believe that p. Note that (3) is the heart of Sensitivity, though it doesn’t capture the whole truth-tracking account. To develop that, let’s apply our conditions thus far to some classic hard cases.

Sorrowing Old Man (At Eternity’s Gate) (1890), Vincent van Gogh
Is suicide really possible? By ‘suicide,’ I mean the intentional taking of one’s own life, which is the standard understanding of the word, but I also mean something slightly deeper than that. I mean it in a sense in which the person chooses death, not because it’s the only option she or he sees, but because she or he prefers it to life. Allow me to illustrate with a familiar scene.
A man stands before the frame of an open window, looking down from several stories up. He was driven there by the smoke and flames of a fire that continues to rage towards him. He must choose: fall or fire? The choice soon becomes obvious, but, of course, there is no real choice here.
Perhaps all suicides are like this, but not always obviously so. Perhaps many so-called suicides result from a complex array of tiny, barely perceptible forces that, as they accumulate, inch their victim day by day closer to the moment in question. When that day comes, the victim, overwhelmed, blinded, and choked by the now massive firestorm that envelopes him, sees only one way out. Continue Reading →
