Performance Philosophy

Performance Philosophy

There is one aspect of being a philosophy professor that I don’t miss: the performance aspect. I mean the giving of lectures and conference presentations. I didn’t hate it, but I didn’t much like it either. It doesn’t mesh with the essential work of being a philosopher, i.e., thinking, reading, and writing. You have to transform into being a performer. It’s not that I don’t like performing tout court: I was a drummer and a gymnast, and both are types of performance. I’m not against “showing off”. But philosophy is not inherently a theatrical matter; conversational, yes, but not like acting or dancing. I always felt that performing philosophy was somehow debasing it, besmirching my thoughts. I remember at Oxford once when Julie Jack asked me, “Are you performing this afternoon?” I icily replied, “Well, I am reading a paper”. Then there was the time when I was visiting at UCLA (1979) and a young American guy took it upon himself to advise me on proper paper-presentation comportment: “You need to maintain eye contact, establish communication with the audience”—that type of thing. I haughtily informed him that in England we let our words speak for themselves. He was genuinely baffled. I am all in favor of insulting the audience, just to show that I have no desire to be popular with them. You should always maintain the impression that you are indifferent to the audience’s reactions, truth being your only concern. Anyway, there is always some idiot who thinks it’s time for public combat—a type of competition—and this person needs to be dealt with accordingly. So, my lecturing style was extremely unflamboyant, though not without dashes of humor. I wasn’t there to entertain. I think the theatrical-entertainer model has done significant harm to philosophy in the USA: it has turned philosophy into a branch of PR, a form of social manipulation. I name no names, but pick your favorite philosophical performer. Perhaps the worst kind of philosopher is the one who acts the part of a “serious academic”: the glasses, the jacket, the cadences and posture. Really, one should seem uncomfortable and out of one’s natural element, slightly embarrassed by the whole thing. Anyhow, I no longer have to tolerate this descent into showbiz. I spend my time in the recording studio, so to speak: no more concerts and public appearances. Philosophical performance is distracting and tiring, and not of the essence. If you want to perform, become a musician or an actor or a gymnast. If you want to philosophize, keep away from the spotlight.

Here Comes the Sun Again

A parody of the Beatles’ Here Comes the Sun.

 

Here Comes the Sun Again

Here comes the sun again

Smiling its salesman’s smile

Sun, you are so seductive

You want to hold me for a while

Oh sun, you’re irresistible

How can I turn you away

When I feel your warmth on my face

I know it will be a good day

Sun, sun, sun, here you are now

Sun, sun, sun, yet so far now

But now I know you better

I know your wily ways

You tricked me into loving you

While you sent down your deadly rays

We’ve taken down the barrier

So you can bring your heat

We’re like a dog trapped in a car

Hoping to be released

Sun, sun, sun, there you go now

Sun, sun, sun, keep it low now

You feel so close to home today

Your breath can easily roast us away

Every day feels like another scorcher

Life has become a sunny torture

Sun, sun, sun, please go away now

Sun, sun, sun, leave us to pray now

Sun, sun, sun, it’s enough now

Sun, sun, sun, we’ve had enough now

Sun, sun, sun, we’ve had enough now…

A Road Song

/0 Comments/in /by

I’m reading Paul McCartney’s The Lyrics and figured I needed to write a road song (compare Route 66).

 

A Road Song

I got my foot on the gas

I got my hands on the wheel

I’m heading down to Miami

To seal the deal

I’m a real estate broker

If you really want to know

I sell people homes

For maximum dough

Don’t hold it against me

I’m vital you see

At least I don’t travel

With my Little Friend next to me

Ha!

I got my foot on the gas

I got my hand on the wheel

I’m speeding down to Miami

To put the seal on the deal

I’m hoping to reach there

Before it gets dark

It’s my first time in the city, you see

And I don’t know where to park

I think this is my big one

The one that will make me

When it’s over and done with

No one can ever shake me

So alone I drive

With my radio alive

Yeah, I get my jive

On the I-95

I get my jive

On the I-95

I’m gonna seal the deal

I’m gonna make it real

And then I think I’ll go

For a solitary meal

Yeah, I’ll wrap up the deal

With a solitary meal

A quiet solitary meal

With my hands on the wheel

My hands on the wheel..

Evolution of Pain

/13 Comments/in /by

This paper follows on from “The Cruel Gene” and “Pain and Unintelligent Design” on this blog.

 

Evolution of Pain

Pain has evolved over many millions of years. Presumably it had primitive forms that were subjected to natural selection. It was honed and whittled, modified and amplified. There are now several species of pain, each no doubt fine-tuned to achieve a certain end. It is very widespread among animals—if not universal, then close to it. If we think of it as a mental organ, we can model its evolution on the evolution of organs in general: there is a kind of structure-function matching, with the organ designed to have certain functional effects (ultimately survival and reproduction). It probably evolved very early given its survival utility, and it has persisted robustly over the millennia; it is unlikely to become obsolete or extinct. We can think of it as the eyes of the body: it “sees” danger and reacts to it. It is analogous to a perceptual faculty. Perhaps it evolved in prey animals (which includes nearly all animals, since nearly all are prey to some animal at some point), because they need to be sensitive to the teeth and claws of predators. Perhaps some animals perceive it more exquisitely than others, depending on their vulnerabilities. A lack of body armor would favor greater sensitivity to pain—there is no need for pain perception if your armor is impregnable to predators (and rivals). What we can be sure of is that pain was rigorously selected for according to its costs and benefits, like any other biological trait. It feels and acts the way it does for good reasons. There are two puzzles about this. First, the costs are considerable: yes, you avoid the painful stimulus, which is all to the good, but you also incur serious liabilities because of general debilitation. An animal in pain is often hobbled by the pain, unable to function, like an athlete in pain. True, this can be helpful if rest is needed, but nature is not always so obliging as to allow for such rest. Second, the pain gives rise to other effects than those of avoiding the painful stimulus, such as overt expressions of pain (grimaces, cries). What is the point of these? It is hard to avoid the conclusion that they are communicative: they let other animals know you are in pain. But this is puzzling, because it isn’t as if other animals will automatically come to your aid—instead of sensing weakness and attacking you. You might want to keep it a secret that your right leg is hurting, or that you have a headache and are not up for a session of head butting. So, pain might not be the simple adaptation we assume: too much downside and too many collateral effects. We can take it that this is not the result of insufficient fine-tuning, which will be rectified in due course; on the contrary, pain mechanisms must be highly adapted by now, not still replete with glitches. Pain responses have been well-nigh perfected over evolutionary time; natural selection has made them as wondrous and efficient as eyes. This will no doubt involve making pain as painful as is compatible with proper functioning, which is obviously pretty damn painful. Good pain is bad pain, so far as evolution is concerned (those selfish genes!). Pain has evolved to be bad, not mild and tolerable. And it has produced a biologically marvelous trait, truly spectacular: pain is remarkably bad, devilishly so. Natural selection has done its job and done it well: it has produced organisms that really hurt—as it has produced eyes that see really well. It has brought pain to the pitch of perfection, survival-wise; it’s hard to believe it could get any worse, subjectively speaking. It has labored long and hard to make us suffer, to ruin our days, even to make us wish for death. Quite an achievement! The genes must be proud of themselves, but the animal must carry the burden. That is the logic of evolution by natural selection playing itself out: animals have whatever traits enable the genes to survive, pleasant (orgasm) or unpleasant (pain). But there is a residual puzzle: why not use reflexes instead? The patellar reflex allows the organism to move rapidly and effectively, but no pain is involved; same for the blink reflex. So, why must a stubbed or squashed toe be accompanied by intense pain—why not arrange the nervous system so that the foot is quickly and reflexively withdrawn but without the intervening agony? The pain sensation doesn’t seem necessary to the function; it seems like a gratuitous (indeed sadistic) add-on. The only thing I can think of is that the pain is somehow necessary for ongoing flexible voluntary behavior in the presence of harmful stimuli, as in managing a broken bone or a burn. But though that seems true as a matter of empirical fact, it is difficult to see why it has to be true. Presumably it has just turned out over the course of evolutionary time that pain is a more efficient way of handling injury than a purely reflexive and pain-free method; but why this should be remains obscure. So, the existence of pain is something of an evolutionary puzzle, especially given its functional downside (its phenomenological downside counts for nothing in the evolutionary game). It clearly evolved over millions of years and is close to universal, but it’s puzzling why it exists at all as an adaptation. It must have evolved in multiple species many times (convergent evolution), but its rationale is far from obvious (unlike the eye). Pain is puzzling, biologically and philosophically, despite its undeniable reality. Some animals do quite well without it—jellyfish, insects, worms—but many live by it (literally), despite its manifest aversiveness. It is the only adaptation bequeathed to us that we would rather be without—that is intrinsically nasty. Suffering may be adaptive to life, but it is also the bane of existence. It is really the only thing that can make life not worth living, yet it exists to serve life. Pain is an enigma that we could live without.[1]

[1] Imagine the amount of pain that has existed over the course of evolutionary time in all animal species. It doesn’t bear thinking about. Earth is the planet of pain.

Rejecting the Analytic-Synthetic Distinction

Rejecting the Analytic-Synthetic Distinction

 If we cannot make sense of the idea of a synthetic truth, it looks as if we have to reject the analytic-synthetic distinction (the reverse of post-Quine orthodoxy).[1] There is nothing coherent for the concept of analytic truth to contrast with (a genuine distinction requires meaningful things to be distinct). Yet there is some sort of distinction because not all statements are analytic (unless we could somehow make good on such a thesis—no easy task). It just needs to be re-conceptualized, re-thought. We must drop all epistemic attempts to capture the distinction and abjure such locutions as “true in virtue of the world”. Perhaps we need to dig deeper and more boldly; perhaps we need to upend some prominent assumptions. I am going to do just that, taking my cue from Kant’s characterization in terms of “explicative” and “augmentative” propositions. But I am not aiming at Kant exegesis, just philosophical truth (much easier than Kant exegesis). I will aim for maximum clarity and minimal defensiveness—simple not subtle (we can add the subtlety later). So, here goes: analytic propositions (so-called) are really identity propositions concerning concepts (also properties); synthetic propositions (badly so-called) are propositions asserting the co-instantiation of distinct concepts (also properties). Analytic statements say, “The concept F is identical to the concept G”, while synthetic statements (read non-analytic statements) say, “The concept F is co-instantiated with the concept G”. For brevity I will say that the former are identity statements and the latter are co-instantiation statements. The basic picture is that our conceptual scheme (system of concepts) has two sorts of structure, constituent structure and associative structure, and these structures concern conceptual relations in a broad sense. Thus, a given concept can be related to its conceptual constituents via constituent structure (what it is “made of”), and a concept can also be related to other concepts (not its constituents) by associative structure (what it can combine with). For example, the concept bachelor is related to the concept unmarried via the relation of constituency, while the same concept can be related to the concept happy via the relation of association (joining, juxtaposition). Distinct concepts can be combined in the same proposition, and concepts can contain other concepts. I take it this idea will be familiar; it is intended to be. Then the thesis is that the latter relations give rise to analytic truth whereas the former relations give rise to synthetic truth (as it is misleadingly labeled). We might instead call these “truths of containment” and “truths of association” so as to rid ourselves of unhelpful connotations (they are as bloodless as I can manage). Kant’s terminology is tacitly epistemic: “explicative” means “articulates antecedently possessed knowledge”, while “augmentative” means “adds to our pre-existing knowledge”. I am just talking about abstract relations between mental elements that may map onto such epistemic notions but are not defined by them. In fact, I want to take a further step away from the cognitive and say that the official theory is to be stated in terms of properties (references of concepts): properties can contain properties and they can also be co-instantiated with properties. These are relations that obtain in the non-mental world—in the world of external objects. We may say (if we like) that analytic statements correspond to identity facts involving properties, while synthetic statements correspond to facts of co-instantiation involving properties. We may also say that analytic statements are about concept parts while synthetic statements are about concept partners (or property parts and property partners). What is crucial to the distinction is that partners are not parts; co-instantiation is not identity. It is this that distinguishes the synthetic from the analytic. It has nothing intrinsically to do with knowledge or experience or justification. The distinction is emphatically not the same as the a priori-a posteriori distinction. It is about truth-makers, i.e., about two categories of truths. It says nothing about what is trivial or non-trivial, informative or uninformative, known by experience or known independently of experience, having cognitive value or not having cognitive value, being intuitive or being perceptual. It is a distinction drawn at the level of metaphysics not epistemology. It has nothing intrinsically to do with rationalism and empiricism, or revisability, or infallibility. The claim I am making is simply that this is the best way to re-conceptualize the traditional distinction labeled “the analytic-synthetic distinction”; and it may not correspond to the intentions of people casually employing that phrase. I would be quite happy to allow that it is not a version of that distinction (whatever it is exactly) but a new distinction altogether—a better, more intelligible, distinction. I am not doing intellectual interpretation; I am doing philosophical excavation—of metaphysical reality not intellectual history. The distinction, as I understand it, is basically about the ontology of properties—how they stand in relation to each other. Does this suggestion serve to unify the class of non-analytic truths? Yes and no. Yes, in that it says what is in common to all non-analytic truths, viz. concept association (without concept identity); but no, in that there is a huge variety of what we call properties, ranging from physics to ethics, psychology to arithmetic, with nothing to unite them except the very general notion of a property (attribute, characteristic, predicate). There is nothing like the traditional idea that synthetic truths are all known by sense experience, or add to our knowledge, or produce a sense of cognitive augmentation. The class of non-analytic truths is not unified in these ways; it is simply the class consisting of truths that concern distinct properties that are said to be co-instantiated. This may have consequences for epistemology and psychology, but it is not defined that way. We can put the point as follows: propositions have the power to contain concepts that have other concepts as their constituents, and they also have the power to contain concepts that are instantiated together—the former gives rise to analytic truths, the latter gives rise to synthetic truths. We can thus preserve the substance of the analytic-synthetic distinction without running afoul of the problems surrounding the usual ways of formulating it. It is really much more of a truism than has been supposed, though a truism with serious metaphysical commitments. The analytic-synthetic distinction is rooted in deep facts of nature, ultimately the nature of properties.[2]

[1] This paper follows on from my “Are There Synthetic Truths?”

[2] I think the fundamental problem with the usual discussions of the analytic-synthetic distinction is that people decline to recognize that the question is metaphysical, not linguistic or epistemological. Even Kant gave it an epistemological slant that influenced all later discussions, though it is au fond not an epistemological distinction. It is about the nature of truth (or truths) as such not about our knowledge of truth (truths). We should not psychologize the distinction.

Are There Synthetic Truths?

/0 Comments/in /by

Are There Synthetic Truths?

There is a tradition, stemming from Quine (but not pre-dating him), claiming that the concept of analytic truth is undefined, or ill-defined, so that the analytic-synthetic distinction cannot be made sense of; accordingly, there are only synthetic truths. I think this is the opposite of the truth. Nothing is true but reality makes it so, Quine tells us, contrasting reality with meaning. And it is routine to hear that a synthetic truth is one that is true “in virtue of the world” (not language)—or perhaps in virtue of “the facts”, or “extra-linguistic reality”. But these formulations are by no means clear and run into immediate objections. In the first place, language and meaning are clearly part of reality or the world, so reality or the world cannot be construed as excluding them: yes, nothing is true but reality makes it so, but the reality can be either meaning or non-meaning. It might be thought that there is an easy fix: just say that a synthetic truth holds in virtue of non-linguistic reality. Now the problem is that some synthetic propositions are about linguistic reality—take any statement about the languages of the world or what a particular word means. Clearly, we need to say that a synthetic truth is non-analytic, but (a) that would not suit Quine (though it’s fine by me) and (b) it is purely negative. This throws us back to talk of reality and the world and facts: we need to say that synthetic truths concern the part of reality that doesn’t include facts constituted by meaning relations (or something along these lines). Now a new problem confronts us: what is this entity and what composes it? Is it a totality of facts, a totality of objects, of objects and properties, of facts and values, etc.? This is beginning to sound ominously metaphysical, inherently contentious, and probably meaningless. And there is this problem: presumably we can’t mean that a given proposition is true in virtue of the whole of this world, or else each proposition is made true by the same thing; so, we need to say that parts of the world correspond to each synthetic proposition (unlike analytic propositions). This puts us on a familiar and dreary path: logical atomism, negative facts, complexes of objects, and the difficulty of supplying identity conditions for the putative truth-making entities. We didn’t think we had signed up for this rigmarole when we declared that there are synthetic truths! But we started talking about “the world” so what did we expect? We are thus driven back to saying that synthetic truths are non-analytic truths, with no positive characterization of them given (as well as uncritical acceptance of analytic truth). And here the nub of the matter emerges from the mist: the concept of the synthetic is parasitic on the concept of the analytic. It is the concept of truth in virtue of meaning that wears the trousers (as Austin would say): we need that concept if we are to carve out a territory labeled “synthetic truth”. The latter concept has no content without the former concept. It would be different if we could define “synthetic” as (say) “perceived by the senses”, because then we wouldn’t have to make do with the amorphous concept the world; but that is obviously too narrow, too restrictive. The problem is that the class of truths that are not analytic is a ragbag possessing no inner unity; it isn’t a natural metaphysical kind. Its sole content is given by the concept of the analytic, which trades in the restricted (and legitimate) concept of meaning. Note that “synthetic” is not a very descriptive term; it is really just a label for what is left over when we have listed all the analytic truths. The concept lives and dies by its contrast class. But that means that we have no unitary positive concept of the synthetic suitable for bringing together all that is supposed to fall under it. Moreover, we have a decent criterion of identity for meanings, viz. substitutivity inside belief contexts, but we don’t have such a criterion for whatever is supposed to make synthetic propositions true. Hence the vague and woolly talk of the “world” and “reality”. There is the general concept of truth and the specific concept of analytic truth, but there is no concept of synthetic truth save a hopelessly disjunctive one. It is the “craving for generality” that leads us to think that we have identified a metaphysical natural kind. All we really have is a philosopher’s invention—a contrivance, a fabrication. It is certainly not a concept of science, or even of linguistics. So, we cannot hope to base a philosophy on the concept of synthetic truth, saying such things as that all truths are synthetic; all that can mean is that no truths are analytic, relying on an antecedent grasp of that concept. This is obviously no help to a disciple of Quine, but even a firm believer in analyticity won’t be encouraged by a concept so negatively defined. I think myself that analytic truth is adequately defined as truth in virtue of meaning alone, but that synthetic truth has no adequate definition—certainly not one in terms of truth in virtue of “the world” or “reality”. You might hope to define it as “what is known by empirical investigation”, but that is objectionably epistemic (what if the truth can’t be known?), and also fails to count knowledge of one’s own mental states as knowledge of synthetic truths.[1] There is, in fact, little effort to define the category of the synthetic, so that the concept is left at a vague and intuitive level, explained more by example than by general definition. To say that all meaningful statements are (or must be) synthetic is therefore meaningless metaphysics, which is ironic in the circumstances. We literally don’t know what it means (Kant has a lot to answer for). In its ordinary use the word means “not genuine; unnatural” (OED) and that does indeed correspond to something real: for the idea of a synthetic truth is a synthetic idea, i.e., a fake classification. There are no synthetic truths (but plenty of analytic truths); there are just truths that fail to be analytic—as there are many types of truths that fail to be ethical or psychological or economic or about me. Not belonging to the class of analytic truths is not a way of forming a unified class of other truths. We can distinguish classes of truths within the non-analytic class, but no positive trait unifies them, whereas analytic truths form a well-defined class. It is the concept of analytic truth that is in good theoretical shape not the concept of synthetic truth. And isn’t this what any card-carrying rationalist would say?[2]

[1] The OED is uncharacteristically unhelpful here: as its second definition of “synthetic” it gives us “having truth or falsity determinable by recourse to experience” (this is relegated to Logic). This is a frankly epistemic definition of what should be a logical or metaphysical concept, and is therefore a kind of category mistake. It fits the concept of the a posteriori better. Also, how is it supposed to apply to the synthetic a priori, as in arithmetic? Such truths are not verifiable by “recourse to experience” yet are supposed synthetic. Nor do we know that we have beliefs by sense experience (and what other kind of experience is intended?). It looks to me as if the dictionary makers took the philosophers on trust and did the best they could with a dubious (spurious) notion.

[2] The concept of empirical truth is similar in view of the enormous variety of things that fall under the concept of experience. How unified is this class really? Is it as unified as the class of a priori truths? Empiricism is just not a monolithic unified theory, and nor is “synthetism” defined as the doctrine that all truths are synthetic. The metaphysics of these theories is not well defined, i.e., what it is to be an experience or a synthetic truth. More dogmas of empiricism (rationalism fares much better in this respect).

Preposterous Presidents

/3 Comments/in /by

The recent debacle involving the presidents of three top American universities is symptomatic of a deeper and more widespread malaise. The moral obtuseness and intellectual ineptitude of these three women is just part of a general degradation in American universities and intellectual life. I won’t go into the causes of this, but what appalls me the most is that they are under the illusion that they are demonstrating superior moral and intellectual qualities. They are not. At root this comes from bad philosophy, indeed obviously bad philosophy. Real philosophy used to oppose this kind of inept “thinking”; now it is succumbing to it.

Consciousness, Paralysis, and Functionalism

Consciousness, Paralysis, and Functionalism

Paralysis has been regularly used to defeat behaviorism and its descendant functionalism. How can the mind consist of behavior if paralysis is consistent with having a mind? The objection is clear and strong: paralysis shows that behavior is not required for consciousness to exist. To have a conscious state is not to move in a certain way. It might even be that a conscious being has never moved and never will and has no disposition to move. What I want to point out is that much the same objection applies to attempts to define mental states in terms of their mental effects: what a mental state does internally is equally incapable of defining it, because of the possibility of mental paralysis. I will call this the “paralysis argument”. The argument is not complicated; in fact, it is embarrassingly simple. Consider a pain occurring at time t: it may have many mental effects—forming the belief that you are in pain, desiring to escape the pain, comparing it to other pains you have had, laying down a memory of the pain, thinking you will later write about the pain, deciding not to do that again, and so on. All these occur after t, radiating out from the pain, eventuating in overt action. Now suppose that some neural catastrophe were to afflict you, interrupting the causal connections: you don’t and can’t have those mental effects of the pain; you have the pain but the causal sequence is abolished. The neurons fail to send the signals to other areas of the brain, shutting down the mental effects of the pain. You are mentally paralyzed. Clearly, this is consistent with having the sensation of pain, since the effects occur after the pain. But then, such effects are not a necessary condition of feeling the pain, and so cannot constitute having it. The situation is exactly like bodily paralysis except that the causal sequence is interrupted at an earlier point. The effects could extend further out than the body into the world at large and could be interrupted at any point; the situation is not different going in the opposite direction. There can be behavioral paralysis and mental paralysis—as well as “paralysis” with respect to environmental effects. But then, we can’t define mental states in terms of their effects, physical or mental, which means that functionalism won’t work. What a mental state is can’t be reduced to what it does, mentally or physically. To be a pain is not to have a certain functional role, since the pain can exist without the functional role existing. People have argued that functional role is not sufficient for a mental state, but it is also not necessary, by the paralysis argument. We don’t see this kind of paralysis often, if at all, but that is because the relevant parts of the brain are not as exposed to injury or interference as much as the spinal cord; but as a matter of principle the cases are not different. The fundamental problem is that pain and its effects are distinct existences (as Hume would say), so that one can’t be the other. Once this point is appreciated (it isn’t a difficult point to grasp) we can develop two further anti-functionalist arguments: the “time-lapse argument” and the “ignorance argument”. The time-lapse argument points out that the effects of pain post-date the pain, but the pain doesn’t post-date itself; so there can be no identity between them. The ignorance argument points out that you could know you are in pain without knowing its effects, since these are different things; so there can be no analytic or a priori connection between them. You might simply become mentally blind following the occurrence of the pain, so that you are ignorant of its mental effects, or those effects don’t occur because of mental paralysis. Your knowledge that you are in pain cannot then consist in the knowledge that you are in a state with such and such mental effects. Unlike materialism, functionalism has problems with time: materialism invokes a contemporaneous brain state, but functionalism invokes a temporally extended causal sequence, thus incurring the problems outlined. As I said, pretty simple stuff.[1]

[1] This isn’t to say that functional role could not be employed less ambitiously in an account of the mental, as merely an aspect of the mental state; but then, it isn’t identical to the mental state. This would be a kind of weak functionalism analogous to various kinds of weak materialism. Classical functionalism, like classical materialism, is a case of theoretical exaggeration, taking an essentially sound point and overdoing it.
