Knowledge and Reasons for Belief

 

 

Suppose I believe that you plagiarized me. Suppose that it’s true that you plagiarized me. Suppose also that I have irrefutable evidence that you plagiarized me, in the form of my exact words appearing in a paper of yours (this evidence exists precisely because you plagiarized me). So I have a true justified belief that you plagiarized me, where my justification is not accidentally connected to the truth of what I believe. Do I then know that you plagiarized me?

            What if I have always hated you and feel a strong sense of professional rivalry with you? I will believe anything against you no matter how flimsy the evidence may be. I would jump at the chance to accuse you of plagiarizing me. However, I am not consciously aware of these negative feelings and dispositions; I believe that my animus towards you is based purely on objective facts (you plagiarized me!). Suppose that the reason (cause) I believe that you plagiarized me is this unconscious animus; I would have believed it even in the absence of the evidence I have. That evidence rationally justifies my belief, but it is not the reason I have that belief. In fact, I care little about whether my belief concerning you is true—what I care about is that it makes me feel good to hold negative beliefs in your regard. The evidence I have is convenient for convincing other people of your culpability, but it plays no role in the formation of my belief (in fact the evidence is not as conclusive as I could wish, since you might have just forgotten where you got the ideas in question). My belief is caused by my unconscious attitudes and not by the objective evidence. There are good rational reasons for my belief and I am in possession of them, but they are not the operative reasons for me. My reasons are actually bad reasons for belief. I am forming my beliefs about you in a defective manner; I fall well short of epistemic responsibility.

            It seems to me that in these circumstances I don’t know that you plagiarized me. My belief is true and justified, and the justification is properly connected to the truth, but still I don’t know. Anyone else in possession of the evidence I have would know, but I don’t know. They would have their belief shaped by the evidence, rationally so, but not me: the reason for their belief would be the evidence, but in my case that is not the reason for my belief. In order for me to know the evidence would have to be the reason for my belief. Thus the following conditions are necessary conditions for knowledge: the proposition must be true, you must believe it, you must be justified in believing it, and the justification must be the reason you believe it.  [1] Simply put, the justification must cause the belief; alternatively, you must form the belief rationally. Irrational belief formation is logically consistent with possession of a rational justification, and in such a case knowledge is not possessed. True, you plagiarized me, and I have eminently good reasons to believe that you did: but I don’t know it, because I didn’t form my belief responsibly and rationally. Knowledge is rational true justified belief. Psychology must recapitulate epistemology.

 

  [1] Whether these conditions are sufficient is another question, about which I remain agnostic.

Panpsychist Phenomenalism

                                                Panpsychist Phenomenalism

 

 

Phenomenalism analyzes material-object statements in terms of the actual and potential experiences of perceivers: for a table to exist is for table-type experiences (“sense data”) to exist—say, for it to look as if there is a table. This has the consequence that there can be no material objects unless there are perceivers. But there is another type of phenomenalism that has never to my knowledge been mooted: the thesis that for material objects to exist is for them to have certain experiences, actual or potential. Given the truth of panpsychism, we have the resources to account for existence in experiential terms: it is the table itself that has table-type experiences. The table feels itself to be a table—in some sense modality or other. If the table is round and brown, then it has experiences of itself asround and brown. Thus the table doesn’t depend on our experiences in order to exist; it depends on its own experiences—which can exist independently of ours. Material objects, on this theory, are self-perceiving beings, and in this self-perception lies their existence. Once we allow that material objects have an inner psychic dimension, we can put this dimension to work in formulating a phenomenalist theory. Someone attracted to phenomenalism but unhappy with the traditional version might welcome this new version: everything turns out to be mental, but human experience is not the root of all being. Given panpsychism, it is natural to infer that the experiences inherent in all objects are experiences of the objects they inhabit—what other kind of intentionality would they have? Not of stars and bars, to be sure. Panpsychism can thus claim (a) to solve the mind-body problem, (b) to answer the question of the ultimate nature of matter, and (c) to provide the foundation for a phenomenalist view of the objective world. Nice work! As a bonus, we provide an answer to the question of what kind of mental properties material objects possess—they are best understood as perceptions of those objects themselves. A round object, say, will be analyzed in terms of sense data of roundness—sense data had by the object itself. The general shape of the theory is idealist, since concrete reality is constituted by mental properties, but these properties are not instantiated by us. The world is a world of Other Minds.

            Panpsychism might, however, not be true (I don’t think it is true myself): does that rule out panpsychist phenomenalism? Perhaps surprisingly, it is not clear that it does: for we can avail ourselves of counterfactual conditionals in the traditional manner. Phenomenalism does not require actually existing experiences but only potential experiences—the kind you would have if you perceived the object in question. The existence of a table requires only the possibility of experiences—the kind you would have if you gazed at a table (“permanent possibilities of sensation”). So why not say that the existence of a table consists in the counterfactual circumstance that if the table had experiences they would be table-type experiences? We don’t have to assert that objects actually have a psychic dimension; we merely assert that if they did it would be thus-and-so. Thus we analyze material-object statements by means of conditional statements that refer to possible experiences in the antecedent: if the table had experiences, they would be table-type experiences (not Labrador-type experiences). Logically, this is just like saying that the existence of a table consists in the fact that if I had perceptual experiences now they would be table-type experiences—but I might not actually be having any (my eyes are shut). A blind man could analyze table statements in terms of statements about visual experiences he could have if he were sighted—they needn’t actually exist. Similarly, the resourceful panpsychist phenomenalist could claim that for a round brown table to exist is for the following conditional to hold: if the table had an inner psychic dimension, it would have experiences as of a round brown table. That is, this ingenious theorist analyzes material-object statements in terms of counterfactuals about possible experiences in material objects–he doesn’t have to claim that objects in fact have such experiences. He analyzes ascriptions of properties to objects in terms of hypothetical psychic properties. He can thus claim to give an account of the so-called material world that invokes nothing beyond (possible) mental facts. We can imagine this determined phenomenalist haughtily challenging us to refute his theory. He is like a traditional phenomenalist who allows the possibility of material objects in a world in which no one has any perceptual experiences: he appeals to the fact that such experiences are possible in principle, and his theory is that objects reduce to the possibility of experiences—those you would have if you had senses. Just so, the new kind of phenomenalist could claim that material-object statements can be analyzed in terms of statements about the experiences that objects would have if (contrary to fact) they had any experiences.

            If phenomenalism ever comes back into fashion, its adherents might welcome the addition of this new type of phenomenalism, especially if they have been persuaded that panpsychism is attractive on other grounds. If we have to accept panpsychism anyway, we may as well go the whole hog: mind-body problem, intrinsic nature of matter, and analysis of material-object statements.

Degrees of Consciousness

                                               

 

Degrees of Consciousness

 

 

Think of the last time you sat opposite someone you know well and talked for a while. You had all sorts of conscious experiences: the look of the person’s face, the sound of his or her voice, and so on. At some point you may have said his or her name and simultaneously heard it. Were you conscious of the person’s name during this period? You certainly were at the moment of uttering it, but were you the rest of the time? We can say that you knew the name all the while, and not in any weak or reduced sense. Was the name on the tip of your tongue? No, but it was hovering somewhere nearby; you were not like someone struggling to recall the name, or someone who had never learned it. I am inclined to say that you were conscious of the name during the period in question—as much as you were conscious of other aspects of the person (his or her lip movements, eye color, accent). You weren’t paying attention to these things, but you were conscious of them—they were within your field of consciousness.  [1] Yet your consciousness of the name was not like actually hearing the name, either perceptually or in the form of an auditory image. There were no “name qualia”, though a name was consciously present. Were you as conscious of the person’s name as you were of his or her face? Probably not, unless you kept recurring to it, but it would be incorrect to say that you were unconscious of the name—that your knowledge of it was unconscious knowledge. You were entirely aware of the name at all times (not unaware)—it was an element of your overall state of conscious awareness. It was like your awareness of the sex or nationality of the person.

            Was there anything it was like to be conscious of the name during this time interval? No—there was no subjective impression of the name, no qualitative feel (except when you uttered the name). It was not part of your sensory field. Nor was there any conscious episode of thought involving the name—no inner act of speech containing it (“George is looking handsome today”). The name did not “pass before your mind”. So consciousness does not require these kinds of occurrence: things can exist in consciousness without existing in those ways. It is quite wrong to say that unless an item belongs to consciousness in either of those two ways it is simply unconscious; on the contrary, the name was an aspect of your current total consciousness of the world—you were conscious of the fact that you were speaking to a person called “George”. This is not a fact of which you were unconscious, like the forgotten fact that you once saw George on the subway, or the Freudian fact that you unconsciously hate him. Similarly, you were conscious of your own name during the conversation, though it likely never crossed your mind—as you were conscious that you exist, are a person, are sitting in a restaurant, and so on. Your consciousness can be populated by many things that go beyond the subjectively sensory and the cognitively episodic: it is not all sensory qualia and inner speech–of what passes before and through consciousness. Consciousness is more capacious than that, more inclusive.

            But names are not always consciously present in this way—ripe for the picking. They do not always trip off the tongue with the greatest of ease, as if crossing a perfectly permeable threshold—as if the transition to full consciousness were nothing. Sometimes names are hard to recall, even impossible to recall. In fact, names vary widely in their ease of recall, as everyone knows: sometimes it can take a whole day to recall a name. It is thus natural to say that different names are more or less accessible to consciousness–they can vary in their proximity to conscious awareness. Just as a name can be conscious and yet not at the center of consciousness, so a name can be only faintly conscious compared to another name (sometimes you can recall only part of the sound of a name). That is, we can introduce the notion of degrees of consciousness to mark these distinctions: we replace the idea of a sharp dichotomy between conscious and unconscious with the idea of gradations of consciousness shading into complete unconsciousness. This is not to say that the mind shades into the material world and so has no distinctive reality (whatever that may mean); it is merely to say that the traditional bifurcation into the conscious and the unconscious mind is simplistic and dispensable. What is called “the conscious mind” is more amorphous, more heterogeneous, than people tend to suppose, merging as it does with memory, language mastery, and background knowledge. The proper metaphor is the penumbra not the spotlight (though all such metaphors are misleading). It is misleading to focus on momentary states of sensory consciousness and assume that these are paradigmatic—they are merely one variety of consciousness. Don’t focus on the bat’s current echolocation experience to the exclusion of all else; remember everything that shapes the bat’s total awareness of the world, including such things as its knowledge of where it lives, of the existence of other bats, and of its own bodily orientation. There are boundaries to consciousness, but they are not so narrow as to exclude everything except the “phenomenal” and the “cognitively episodic”. Knowing someone’s name can be perfectly conscious without being either of these things.  [2]

            Part of the point of recognizing degrees of consciousness—or rejecting a sharp division between the conscious mind and the unconscious mind—is to question the idea that only certain types of mental phenomena pose a serious challenge to science and philosophy. It is not as if anything not conscious in the restrictive sense is not a deep theoretical problem: the mind as a whole is a problem not just some segment of it—that which we are currently conscious of in some limited sense. Relying on the model of perceptual sensations gives a distorted picture of the terrain, since these are just one part the mind, and not characteristic of the whole. That is why I picked on the case of knowing a person’s name, which doesn’t fit the model. Being aware of someone’s name in the normal course of speaking to him is just as much an instance of consciousness as anything else, even if such awareness can come in degrees. It isn’t that the mental differs only in degree from the non-mental; rather, mental states can differ from each other in their degree of consciousness. There is no sharp line separating the conscious mind from the unconscious mind but a kind of interpenetration and continuity; this dichotomous terminology itself encourages a false antithesis. Don’t picture the mind as a radiant conscious region adjacent to an unlit unconscious region; picture it instead as an overlapping series of more or less illuminated regions—from bright to dappled to shady to crepuscular to inky. A name can occupy any of these contiguous regions: from the clearly heard to the explicitly known to being on the tip of the tongue to the momentarily elusive to the maddeningly buried. In our efforts to highlight consciousness we should not oversimplify it or assimilate it to one class of mental phenomena; nor should we suppose that what is designated unconscious belongs to a different family from what is designated conscious. These terms are just rough labels for a more complex reality; they should not be allowed to dominate and distort our discussions of the mind.

  [1] Of course, you were not perceiving the name, as you were other aspects of the person, but that does not prevent you from being conscious of it—as you would be if you kept saying it to yourself inwardly.

  [2] The same might be said of our knowledge of language as a whole, but I won’t go into this—the case of names suffices for my point.

Phenomenology of Memory

                                   

 

 

Phenomenology of Memory

 

 

We didn’t need Proust to teach us that memories can be remarkably vivid and emotion-laden, even distant memories. All of us experience those Proustian moments when we are pierced by the dagger of memory—pleasantly or unpleasantly. This is when “it all comes back as if it were yesterday”: there is that uncanny sensation of reliving the past, of re-experiencing what is long gone. Sensory imagery is gloriously vivid and old emotions re-emerge as if from nowhere. The act of remembering has an unmistakable phenomenology that can be as intense as perception. But what does that tell us about the nature of memory itself? What does it tell us about the form in which memories are stored?

            I suggest it shows that memories themselves have a phenomenology. Clearly the original experience had a phenomenology, and clearly the act of remembering that experience has one too—so how could the intermediate stage of stored memory lack a phenomenology? Logically speaking, it could lack a phenomenology, being merely an insentient brain state: but surely the best explanation of the Proust effect is precisely that the persisting memory itself has a phenomenology. The remembering has the phenomenology it has because the underlying memory does—the very phenomenology that is revealed in the act of remembering. The taste of the Madeleine persisted in the memory of tasting it and so did its emotional associations; there wasn’t some kind of gap in the psychological stream from past to present, as if the memory trace had no mental aspect. Phenomenology did not yield to mere physicality over the time interval: the phenomenology bubbled away quietly waiting for its moment in the sun. The reason the act of remembering has the vividness it has is that the preceding memory harbored the very phenomenology that emerges in the remembering. For why should it be thus vivid if the memory itself lacked all phenomenology? Memories such as this are laid down in impressionable children, saturated by charged affect, and they retain the phenomenology of the moment: they don’t lose their pungency just by disappearing from conscious awareness, as if that pungency could be deleted by the mere fact of not being consciously thought about. Indeed, they may exercise a powerful influence on their possessor from their position of unconsciousness (nostalgia, regret, alienation). They do so in virtue of the phenomenology that is intrinsic to their nature as experiential remnants. What else could explain it?  [1]

            If this is right, we can dissociate phenomenology from consciousness. The memory of the Madeleine was not conscious, unlike the original taste and its subsequent recollection, but the phenomenology was continuous—it did not cease when consciousness did. The recollection merely reflects the phenomenology inherent in the memory. The phenomenology was psychologically real during the period of memory storage—just as the intentionality of the memory was psychologically real during that interval. It is not that the intentionality ceased with the initial conscious experience and then magically reappeared at the moment of recollection; it persisted in the interim, encoded in the memory. The memory was about something (the taste of a Madeleine): similarly, the memory retained the subjective “feel” characteristic of both the original experience and its subsequent recollection. This is not the miraculous resurrection of a long-dead item of phenomenology, but merely the reemergence of what had been smoldering all along. Why does the remembrance feel as it does after all this time? It’s because the feeling had never left the memory; it had merely temporarily disappeared from consciousness. Surely that is the natural and plausible thing to say about what happened—not that the remembrance somehow traveled back in time to the moment the Madeleine was tasted, and not that a mere insentient brain state persisted over the interval. The phenomenology was compressed into the memory, considered as a psychological unit–ready to spring forth when the right stimulus came along. It rejoined consciousness after being separated from it for a time, unchanged in its inherent nature. This is why the conscious recollection has the phenomenological character that it has—because it is the expression of a pre-existing phenomenological substrate.  The Proustian kind of case makes this vivid by reminding us of extreme examples of phenomenological persistence.

            By thus separating phenomenology from consciousness we bifurcate the mind-body problem: now we have the problem of phenomenology as well as the problem of consciousness. The former problem can apply to unconscious mental states. In principle we could solve the phenomenology problem without solving the consciousness problem (and maybe vice versa). At any rate, we are dealing with two problems not one. Both are hard: both pose deep problems of theoretical unification. We are dealing with a double mystery.      

 

  [1] We could put it this way: memory is not a zombie—memory is a part of the mind. But what could this amount to if not the phenomenology that characterizes mental imagery and emotion? It is experiential memory, after all.

Universals of Consciousness

 

Universals of Consciousness

 

 

“There is something it is like to be a conscious being”: let’s examine the logical form of this statement. There are two possible readings of it, depending on the scope of the quantifiers: one reading says, “For any conscious being B, there is something L it is like to be B”; the other reading says, “There is something L it is like such that for any conscious being B, B has L”. That is: we can either mean that there is a unique thing it is like for any conscious being, or we can mean that for any conscious being there exists some thing it is like to be that being (not necessarily the same thing in each case). It is clear that those who use this phrase typically intend the narrow scope reading of “something”: they wish to allow that different conscious beings can have different things it is like to be them (hence the bats). The claim is not that every conscious being is identical with respect to what it is like to be them: that would be empirically indefensible and conceptually narrow. Thus the standard employment of the phrase recognizes the variability of consciousness from one conscious being to another—there is no universal thing it is like to be conscious. If we introduce a modal operator into the picture, the claim is, “Necessarily for any conscious being there is something it is like to be that being”, but not, “There is something it is like such that necessarily for any conscious being that being has that something”. In fact, there is nothing it is like to be any conscious being—nothing specific or universal or unique. It could be that conscious beings vary from individual to individual in what it is like to be them, with nothing shared.

            But this leaves open the question of whether there are any universals of consciousness: is there any property of consciousness such that every case of consciousness instantiates that property? Compare belief: every believer has some set of beliefs, but there is no set of beliefs such that every believer has it. But isn’t there something in common to all believing beings over and above the fact that every believer has some set of beliefs? Can’t we say that all beliefs are propositional or involve assent or are potential elements of reasoning? Can’t we even say that all belief systems concern an objective reality, indeed an objective spatiotemporal reality? Where is the parallel for the case of consciousness? All we are told is that there must be a thing it is like to be a conscious being, but we are not told what unites the class beyond this. Is it that nothing further can be said about what consciousness is generally? Contrast other attempts to characterize consciousness: consciousness as intentionality (Brentano, Husserl), consciousness as nothingness (Sartre), or consciousness as an inner process (lots of people). These are features held to characterize every conscious state equally, while accepting that the contents of consciousness can vary from case to case. What plays this role for the “what it’s like” characterization? The obvious answer is that each type of conscious “likeness” has something in common with the others—that there is a universal property of “likeness”. But what is this? The question comes down to whether all senses (actual and possible) share a single phenomenological feature. Without considering the question in detail, I suggest that the only possible answer will rely on some other approach to what consciousness is—say, that it is intentional, or is nothingness, or is inner. Perhaps the most immediately plausible answer is that all senses are presentational: they present a world of perceptual objects to a subject. But then consciousness is being defined in terms of the notion of presentation: to be a conscious being is to be presented with a world. The idea of what it’s like has disappeared from the definition in favor of a kind of intentionality definition. The problem is that we either rest content with a disjunctive definition of consciousness or we resort to another sort of concept in the definition: either we disjoin all the specific things it is like (bats, humans, octopuses, etc) or we find some common property such as presentation. There is no single “likeness” property that runs through all the cases and unites them: each sense has its own proprietary set of qualia, its own distinctive “feel”—there is no universal subjective property common to all senses. There are irreducibly many things it is like.

            The problem is more general. The intuitive motivation for the original definition traded upon the phenomenology of the senses, but consciousness is not confined to sensations—what about thoughts? Thoughts can be conscious, but is there something it is like to have them? Is that something peculiar to a certain class of thinkers (say, bat thinkers) or is it common to all thinkers? The question seems misguided: for thoughts don’t really have a subjective phenomenology in the way sensations do–they are not tied to a specific sense modality. If a being had thoughts but no senses, there would be nothing it is like to be that being (in the original sense of the phrase); yet such a being would be conscious. In order to cast our net widely enough we need some other way to include thoughts along with sensations; and again the notions of intentionality and innerness suggest themselves. The notion of there being something it is like lacks the generality we seek: it can’t include thought, and it fails to find a common feature for the case of sensations (except that there is something it is like to have a sensation). And this is before we get to other denizens of consciousness such as emotion, decision, and remembering. The definition only works for a subclass of conscious phenomena, and it only works well for one type of sensation at a time (we know what it is like to have a visual experience and so we grasp what visual consciousness is—but not consciousness in general). Thus the intuitive notion of “likeness” doesn’t provide a satisfactory definition of consciousness.

            It may be that the scope ambiguity conceals this failure of generality: if we hear the statement with wide scope for “something”, it says that there is something in common to all cases of consciousness (a “likeness” property possessed by every type of conscious state); but it turns out that this is not what is intended (and is not true), so we are left with a disjunctive definition. Perhaps too we have a general tendency to unify the different senses, so we easily slide into the idea that some subjective property applies to them all. But if we try to identify this property we come up empty handed or we resort to another sort of definition. For instance, we can hear the phrase “what it is like to be x” as making reference to a subject and how things seem to that subject: then we can easily suppose that what unites the different senses is the fact that each of them involves a subject being appeared-to, not the subjective quality of what appears (“qualia”). But now that is a very different kind of definition, involving subjects and the relation of being appeared to, not intrinsic features of states of consciousness. It is tantamount to saying that a conscious subject is a subject of experience, or that a conscious state is what a subject possesses in as much as it is appeared to (or some such thing). If we hear the statement in the wide scope way, it sacrifices its intuitive content as relating to specific types of sensation (what we can grasp only from a particular “point of view”); while if we hear it in the (intended) narrow scope way, it fails to capture consciousness in general, since there is nothing it is like that holds of any conscious being. In saying merely that there is something it is like to be conscious, but no specific thing it is like, we fail to unify the cases: for we cannot specify any particular “likeness” property common to all cases of consciousness. This is analogous to saying that a believing subject has some set of beliefs without being able to say generally what a belief is.

I suspect that when we consider the case of the bats we tacitly do assume universals of consciousness (at least of the sensory kind), which is why we find the definition appealing: we think of the comparable phenomenological complexity of our visual field and of our sensations of hearing echoes—we don’t assume that the bat’s experience is completely alien to us. Similarly, we unify our own sensations around such concepts as intensity, foreground and background, multiplicity of stimuli, overlap, perceptual constancy, and so on. These concepts provide a common framework for thinking about perceptual consciousness, and they are not specific to particular senses. They are what induce us to believe that we have hold of the essence of (sensory) consciousness, not the admittedly specific and parochial concepts that apply to particular sense modalities. But then the general concepts are the ones that are doing the definitional work not the specific concepts—in which case it is the wide scope reading that we need. The phrase itself (“there is something it is like”) lumps all this together, enabling us to slide from one reading to another, with the associations natural to each reading. We want to say that there is something it is like to be (perceptually) conscious, not just to be one kind of conscious subject or another; and maybe there is, but the standard formulations don’t say what it is, encouraging us to fall back on specific modes of sensory consciousness.  [1]

            My own view is that the “what it’s like” definition is a useful heuristic to move people’s intuitions in the right direction, but as a proper definition it falls short. It captures at best only certain aspects of consciousness but not consciousness in general—witness the case of conscious thought. Thoughts are not conscious in virtue of being about qualia, and they are not subjective in the sense that to grasp what they are you have to possess a certain “point of view” on the world (i.e. a specific sense modality). They have intentionality and they are also inner states or processes (private, unobservable), but these properties are a different matter. Certainly, if there is something it is like to be x, then there is something problematic about x from a materialist perspective; but that is not to say that everything thus problematic is a case of what it is like. The concept of the inner does a better job of capturing the general nature of consciousness, as well as gesturing towards the reason that consciousness is theoretically problematic. The concept “what it is like” is useful and catchy, but is not the stuff of sound definition.  [2]

 

  [1] Sartre’s Being and Nothingness is a five hundred page book on what it is like to be conscious as such, focusing on the concepts of nothingness, anguish, bad faith, temporality, and so on; it is not about human senses versus bat senses and the varieties of conscious awareness. This is the kind of thing we think we are getting when someone sets out to define consciousness in terms of “what it is like”: not what it is like to be a bat or a human, but what it is like to be a conscious being (to be “haunted by nothingness” etc).

  [2] Compare definitions couched in terms of “seems” and “feels”: “There is some way it seems/feels to be a conscious being”. That has an intuitive ring, but it is surely too narrow to capture the full range of conscious phenomena—is there some way a conscious thought seems or feels? And then there is the question of scope: are there many ways of seeming or feeling or is there some one way common to all cases? Interestingly, we do have available here a single property common to all cases, namely seeming or feeling as general properties; but in the case of “what it’s like” all we can say is that likeness is what is in common to all cases of there being something it’s like. But what is that property exactly—what is it for a mental state to have the general property of likeness? This question is obscure at best. It is telling that the “like” locution is preferred over “seems” and “feels”, which wear their defects on their face as general accounts of consciousness. The phrase “what it’s like” has just the right degree of appeal and obscurity to gain currency.

Expressive Language?

                                               

 

 

 

Expressive Language?

 

 

There are obviously expressive vocalizations in both humans and animals: grunts, groans, sighs, moans, shrieks, laughs, barks, purrs, meows. Some of these vocalizations use the same sounds as spoken speech, such as the common utterance of Ach when something goes wrong; and some have a conventional element, as with Boo and Hurrah. But it is a further question whether such expressive vocalizations qualify as language. On the face of it they do not: these sounds don’t combine to form syntactic strings in the way words do—they are just self-standing vocal emissions. If we think of the human language faculty as defined by a lexicon and a grammar, then expressive vocalizations don’t count as part of the human language faculty. Their resemblance to language proper is confined to the fact that they are sounds produced by the vocal organs, but they don’t have the internal organization necessary to count as language (any more than purrs and barks do). Why such vocal acts evolved is an interesting question, but it is clear that they did not evolve as part of the human language faculty; they are not components of a system characterized by recursive syntax and a finite lexicon.  [1] Also their use is limited to outer expression: there is no internal mental counterpart to such sounds, as there is an internal use of language—we don’t moan and groan silently to ourselves (“in the head”). Of course, we may complain to ourselves, but then we are using genuine language (“I hate going to the dentist”). Our ability to express ourselves vocally is really a separate psychological system from our ability to speak a human language—the two merely sound similar. To speak of expressive language in this connection is an oxymoron.

            This has a bearing on certain philosophical projects and claims. Take the emotive theory of ethics: a moral statement is claimed to be equivalent to an expressive utterance like “Boo” or “Hurrah”.  [2] But such utterances are not part of language, since they have no syntactic structure or lexical composition, unlike the statements they are said to paraphrase. The sentence “Charity is good” consists of words combined according to rules, but the utterance “Hurrah” is not (understood as an expressive performance). It is no more a piece of language than a sigh or a grunt is. That is indeed the point of the proposal: a moral statement is claimed to be nothing more than an expression of approval that lacks the structure of a typical statement. A so-called moral statement is not a statement at all but a mere vocal ejaculation expressing a positive emotion (analogous to clapping). But then how can the one be equivalent to the other—how can a piece of language be equivalent to a piece of non-language? How can something with the formal structure of a sentence be equivalent to a non-sentence? Sentences can paraphrase other sentences, but a non-sentence cannot paraphrase a sentence; it can at best replace it. What the emotivist has to contend is that a moral utterance is not an exercise of the language faculty: it does not consist of words arranged in syntactic combination—that is merely a superficial appearance. But such a contention is massively implausible: how could an utterance of “Charity is good” not be made up of words? The sentence contains words that can occur in other sentences, so are these not sentences either? Everything will go expressive if we follow this line. No, the ethical sentence is a real sentence, a part of language, while its putative paraphrase is not. But then the emotivist analysis has to be wrong. It only seemed plausible because both types of utterance involve vocalization and hence are language-like; but this is a poor guide to the status of an uttered sound—for clearly not all uttered sounds belong to language. More specifically, the cognitive system that outputs “Charity is good” (the language system) is not the same system as that which outputs “Boo” and “Hurrah” (the affective-expressive system).  [3] A swooning sigh is not a sentence, so it can’t paraphrase something that is a sentence. The two have quite different formal properties. A sigh does not have the kind of lexically segmented digital structure characteristic of language.

            The same point applies to attempts to explain sentences such as “I am in pain” expressively, as equivalent to groaning or some such. Groaning is not a linguistic act, though it is a vocal act: it doesn’t have the grammatical structure characteristic of language. We can say that an utterance of “I am in pain” can replace groaning (as Wittgenstein remarks), but it is a replacement by something quite new and unprecedented, since groaning is no kind of linguistic achievement (it predates human language completely). So it is not possible to have an expressive (“non-cognitive”) theory of these kinds of speech acts: they cannot be viewed as expressions in any literal sense. Of course, it is possible to express one’s emotions or sensations by talking about them (“I’m feeling very down today”), but that is not what expressive theories claim—they claim that certain verbal utterances are equivalent to vocalizations that lack linguistic structure. The trouble is that no utterance with sentence structure can be equivalent to an utterance without sentence structure; thus the expressivist is stuck claiming that moral utterances are not the utterance of sentences. Whatever emotions a person may have in uttering a moral sentence it cannot be that the utterance is an expression of those emotions in the intended sense—a mere voicing of an emotion, like sighing or humming. Moral language is part of the language faculty with its characteristic syntactic and semantic structure; it is not some vocal hinterland analogous to laughing or grunting or moaning. Strictly speaking, “expressive language” is an oxymoron (though “expressive vocalization” is not).    

 

  [1] I am alluding here to the kind of view of human language developed by Chomsky: a specific biologically based mental module constituted by finitely many discrete elements that combine into infinitely many hierarchically structured sentences.

  [2] There are several doctrines that are often included under the heading “emotivism”; I am discussing just one extreme thesis, namely that moral utterances are equivalent to expressive vocalizations in the sense explained.

  [3] It would be no use to argue that “Boo” and “Hurrah” just mean, “I disapprove of x” and “I approve of x”, since the whole point of the theory is to deny that ethical utterances are true or false. Such sentences are not expressions at all in the sense intended; they are simply statements of fact. It is essential to the theory that “Boo” and “Hurrah” be taken as not statement-like but as analogous to mere expressions of emotion like laughing or crying. And laughing and crying are not part of language: they are not types of speaking.

Games and Languages

 

 

Evidently, play evolved among animals, including humans: there is a “ludic instinct”. The most likely explanation for this fact is that play provides the opportunity to practice skills that will be useful in the animal’s life—hence its appearance during childhood. But games in the formal cultural sense are not among the instincts of animals; nor are games conspicuous in the animal kingdom. There is no instinct for chess, say, and chess does not exist in animal societies. Games are structured activities governed by rules and these rules have a specific character, namely that they involve the overcoming of unnecessary obstacles toward achieving a goal.  [1] For instance, the game of golf is constituted by rules that forbid the direct placing of balls in holes—the balls must get into the holes by means of clubs wielded from a distance, not merely by dropping them in by hand. A game is not just any old kind of playful activity. I wish to say two things about games so understood: animals don’t play games in the sense defined, and no game is innate in humans. Animals don’t distinguish between activities designed to achieve a certain goal as efficiently as possible (“technical activities”) and activities in which an artificial obstacle is created in order to serve the purposes of a game (such as the net in tennis or the handball rule in football). Animal play, which is real enough, is not governed by rules that proscribe the use of maximally efficient means to achieve a goal; presumably this idea is beyond animals. But even if something like games in this sense did exist in animal societies, they would not be instinctive; games are something additional to instinctive play. Thus in humans no games are innate, though evidently play is. No one is born knowing the rules of chess or baseball or tennis. The origin of games is not natural selection.

            How then do games originate? The obvious answer is invention: people invent games. Two caveats: first, people don’t reinvent a game that has already been invented—they learn a game invented by someone else; second, the invention is not generally a one-off solitary act of creation but consists in a drawn-out sequence of actions gradually honed into the kinds of games we observe. But still, the origin is human inventiveness not genetic endowment: game competence is passed on culturally not by biological inheritance. And it is not that humans originally learned games by observing their natural environment—say, by watching some other species playing games and learning from them. No, humans create games from their own cognitive resources, as they create different kinds of technology (the wheel, the computer)—games are human inventions, neither learned nor innate. We can only invent games because we have a creative capacity—the capacity to bring new and interesting things into the world. This kind of creativity seems generally absent from the animal world, though animals can obviously learn. Animals will never invent snakes and ladders.

 Thus humans have two sorts of capacity in relation to play and games: (a) an innate evolved capacity to engage in play, and (b) a creative capacity with which to invent games (this capacity is presumably itself innate, though its products are not). The innate intersects with the invented: we (instinctively) play (invented) games. Not surprisingly, then, we find a universal tendency among humans to play combined with much variation in what is played. Many different games have been invented in which to express the single universal desire to play. The innate capacity to play might itself involve certain kinds of cognitive and motor competence, and this competence could be quite complex; it is not some kind of lumpish disposition to engage in “frolicking behavior”. It might be structured and rule-governed, generative and unlimited; it might be an intricately organized computational mental module (“the play module”). The play programs might even be digital, recursive, and combinatorial. It is just that they are innate while the actual games played are invented (no innate program for billiards or backgammon). There is interplay between the two levels of psychological reality but the levels should not be conflated, and we must characterize them appropriately (innate versus invented).

            The reason I am making these (I hope) pedestrian remarks is that I want to make an analogy to a far more contested area—language. I want to say that the general human capacity for language is innate but that individual languages are invented—as play is innate but games are invented. The first claim is familiar and I won’t defend it: I shall simply assume that humans are equipped with an innate cognitive structure with the formal characteristics of natural languages (notably recursive syntactic rules and a finite lexicon that combine to produce infinitely many potential sentences).  [2] You can think of this structure as a language of thought: call it LANGUAGE. It is not identical to any human natural language, being more abstract than such a language; it is best understood as a formal computational system instantiated in the brain and deriving from the genes. It is not spoken: whatever its lexicon is the elements of it are not parts of ordinary speech. For concreteness, you might think of it as like a logical language along the lines of quantified modal logic (or whatever your favorite logic is) couched in inscrutable symbols. It is the secret code in which thought expresses itself—the universal medium of mentation. It is not an external spoken language, not even being hooked up to the vocal articulation system. Indeed, it is not inherently communicative but rather a device for expediting reasoning—a tool of thought. Thus LANGUAGE has nothing essentially to do with languages, i.e. spoken systems of human communication. LANGUAGE might have existed without languages ever coming to exist: an internal cognitive structure serving thought but accompanied by no outer system of audible signs. Similarly, play (even complex play) could have existed without the existence of games in the sense defined above; they are something superadded, by no means presupposed. Games incorporate play, but they are not entailed by play. No doubt languages likewise incorporate LANGUAGE, but they are not entailed by LANGUAGE.

            Now I can state my main thesis: languages are invented while LANGUAGE is innate.  [3] Humans found themselves genetically endowed with an internal language of thought and on that basis they erected spoken communicative languages—the former was folded into the latter. Particular languages are thus neither innate nor learned (for who could have instructed the original speakers?); they exist by virtue of human inventiveness. Note as before that this inventiveness is not to be conceived as a singular all-at-once feat of mental construction; it is rather the kind of long drawn-out haphazard process that other cultural inventions are (art, law, politics). But it is still invention, still the exercise of human creativity (not innate endowment or observational learning). Languages are indeed still being invented, reconfigured, changing and growing by human will. They are not like LANGUAGE, the fixed innate system inherited from our ancestors after some freakish genetic mutation and subsequent natural selection. The two sorts of symbolic system have quite different kinds of origin—just like play and games.  [4] That both deserve to be called “language” is neither here nor there: that is a structural description neutral on the question of origin. When languages were invented humans exploited a pre-existing fact about themselves—an internal cognitive structure they did not invent. They linked this structure to the organs of articulation to produce a sound system (possibly a sign system) capable of expressing syntactic combinations—a highly nontrivial task. There was no guarantee that the resources of the vocal system could match the internal structure of LANGUAGE, and indeed some modifications and upgrades were called for. The reason humans invented languages, using LANGUAGE as template, was presumably for purposes of interpersonal communication (though possibly external language further helped as a tool of thought): people had to speak to be heard, i.e. to convey messages–there being no such thing as telepathy. People invented languages as a tool of communication by tapping into a LANGUAGE they did not invent. Hence there are many languages and only one LANGUAGE—as there are many games but only one play instinct (per species). Games and languages are thus part of culture, while play and LANGUAGE are part of biology. Games and languages are products of our inventive faculty, while play and LANGUAGE have their roots in biological evolution (mutation and natural selection).   [5]

            To the old question of how “language” evolved we must split the answer into two parts: (a) how the internal language of thought evolved; (b) how spoken languages evolved (came to exist). These are quite different questions, one question belonging to the science of biology, the other to the study of culture broadly construed. This division corresponds to traditional expectations, if not to many theories popular in the twentieth century; in particular, the concepts of innateness and invention replace the concept of learning.  [6] If LANGUAGE is a tribute to the power of biological evolution, then languages are a tribute to the power of human invention. Clearly our distant ancestors must have been a clever and resourceful lot: they in effect created the language of Shakespeare from a cognitive system not originally designed for external use. This is as impressive in its way as the invention of the cell phone or the atomic bomb.

 

  [1] Here I am following Bernard Suits’ classic treatment of the concept of a game in The Grasshopper: Games, Life and Utopia (Broadview, 2005).

  [2] Chomsky’s oeuvre is the obvious reference: see in particular Why Only Us: Language and Evolution (MIT Press, 2016; written with Robert C. Berwick) on how language evolved and the relationship between internal and external language.

  [3] I also discuss this in “Invention and Language”.

  [4] This is consistent with allowing that some aspects of our utterances are instinctual: not everything vocal is invented, e.g. groans, cries, shrieks, laughs, etc. We did not invent these noises; we inherited them. But such vocalizations are not part of language properly so-called: they are not part of the system of spoken words that combine syntactically. We invented this system—the mapping of meanings onto segmented sounds. We invented the sound-meaning pairings of English, German, Japanese, etc—though not the species-wide expressive sounds speakers of these languages also make.

  [5] This is not to deny that LANGUAGE is embedded in languages as their scaffolding and soul; it obviously is so embedded. It is just to say that language differences originate from invention not inheritance.

  [6] Of course children learn their native language, but languages don’t come to exist in virtue of learning as opposed to invention (unlike, say, geographical knowledge). The concept of learning was connected to empiricism, but the concepts of innateness and invention invoke quite different modes of intellectual acquisition.

Thought and Time

                                                            Thought and Time

 

 

A speech act occurs in time: it has a beginning, middle, and an end–it can be clocked. The more words a sentence contains the longer it takes to say it. Some people speak more quickly than others, thus taking up less time to utter the same sentence. Writing is the same: you start on one side of the page and scrawl your way across to the other side, all this taking a certain amount of time. Call this generative process sequential assembly: the utterance (by mouth or hand) proceeds by starting with an initial element and then adding elements until the complete act is performed. Evidently, this is because of the nature of the generative process—making sounds with the mouth and marks with the hands (or shapes in space for sign language). We can’t make two (or more) sounds at once and we can’t make two (or more) marks at once. Hence utterances unfold in time. Parts of speech acts occur at different times.

            But what about thought—does it result from sequential assembly? The answer is not immediately obvious, as it is for speech and writing. What about inner speech when words “go through the mind”? This does seem to take time and to be sequential: silently say the sentence, “Monogamous marriage is doomed to failure” to yourself, being careful to enunciate each syllable. The process begins with the syllable Mon and ends with the syllable ureand takes a definite amount of time (about 2 seconds in my case). It is tempting to see such silent speech as the internalization of noisy outer speech, so we might well suppose that the temporal properties of outer speech are preserved on the journey inward. The organ of speech articulation operates sequentially and it preserves this design feature when deployed inwardly. We certainly don’t want several auditory images, corresponding to different words, to co-occur in consciousness—the inner sounds need to be separated in time. It is a bit puzzling why inner speech should mimic outer speech in this way, given that we are not using the vocal organs to generate the sentence in question, but it seems to be the case.

What should we say about non-verbal thought? You have a thought and no sentence of your spoken language runs through your mind; the thought is purely conceptual. It does not appear that such a thought is assembled in the sequential manner described so far: the process does not proceed by first producing an initial element, then adding a further element, then repeating this operation till the thought is complete—all this occurring over a finite period of time. The thought seems to be produced by simultaneous assembly—all at once. Some generative process selects a set of concepts and then operates on them simultaneously to produce a complete thought; there is no time at which the thought is only half finished or close to being complete or just getting started. The thought may take some time to form, but it appears to come fully formed, not in dribs and drabs. It is as if the thought is projected all at once onto a screen from an array of concepts stored in the mind. Verbal utterances are likewise assembled from a store of elements, but they come into existence in a temporal sequence; thoughts, by contrast, appear to arise without temporal sequencing. The machinery of thought production must thus operate by different principles from the machinery of utterance production.

It might be supposed that this difference counts against the idea of a language of thought, but that presupposes that linguistic operations are always temporally sequential—that sentence construction must occur in linear order. However, sentences could be constructed objects and yet not constructed by an ordering from beginning to end: instead all the pieces are slotted into place simultaneously. Then thought will follow this process of production, apparently emerging without construction (we don’t introspect the opening segment of a thought and then wait for the later segments to appear). But we can infer that this property of thought counts against the idea that the language of thought mirrors outer language in its mode of production: assembling inner sentences to act as the medium of thought is not any kind of utterance—if that means some kind of temporally extended process. Thinking in language is thus not a form of speaking to oneself—it is not inner saying. It is inner symbol manipulation, to be sure, but it is not temporal concatenation—not adding one symbol to another over time. This also means that it is not like inner speech, properly so-called, even unconscious inner speech, which is sequential. To put the point differently, the brain produces sentences in the language of thought by means of a parallel process: it inserts symbols into sentences simultaneously—in parallel. For example, it might take the set consisting of “John” and “runs” and simultaneously insert these words into a sentence frame of the form Fx, where this represents the grammatical subject-predicate form. It doesn’t insert one and then the other, but both together—and similarly for longer sentences. Putting it biologically, we have an innate faculty of simultaneous linguistic assembly, which presumably evolved at some point, and this faculty is what enables us to think as we do.  [1] At a later point, when we acquired spoken language, we began to employ sequential assembly; but the language of thought itself operates by means of simultaneous assembly (which is not to say that the process is instantaneous).

Two questions may be raised about this picture, neither of them easy to answer. The first question is whether it is conceivable that thought should have a sequential mode of assembly: Are there possible beings that think in the way that they speak? Could there be fast and slow thinkers as there are fast and slow talkers? Could someone start a thought and be interrupted in the middle of it, like uttering only the beginning of a sentence? Could there be thoughts that take a full hour to put together? Would it possible to think John runs spread out over a period of thirty minutes? Can you intend to have a certain thought but then fail to have it through lack of time? These things certainly sound strange, but is that just because we are so used to our simultaneous mode of thought production? Maybe Martians evolved a sequential style of thought production, so that they think much as they speak.  

The second question runs counter to the first: am I not exaggerating the simultaneity of thought—is it perhaps just that thoughts form very quickly, so that we don’t notice their temporal character? After all, it may be said, there are sequences of thoughts, as in a stretch of logical reasoning, and these sequences are spread out in time—so why aren’t the individual thoughts that compose them also spread out in time? Also: what about extremely complex thoughts—don’t they take time to reach their conclusion? Here we have to ask whether such duration as there is to thoughts results from sequential assembly or from some other source. Thoughts may well take time to form (the brain needs time to do its thing), but are they assembled in the manner of spoken utterances? When someone has a conjunctive thought, say, do they first think the first conjunct, then insert conjunction, and finally think the second conjunct? That sounds wrong to me, as if the thought isn’t conjunctive until the pieces are all glued together over time—wasn’t it conjunctive from the start? Or rather, there is no start, just a fully formed conjunctive thought taking shape in the mind. As to reasoning, it is consistent to suppose that the arrangement of thoughts into an argument is a sequential temporal process without supposing also that thoughts themselves are sequentially assembled. True, we don’t engage in parallel reasoning, with premises and conclusion simultaneously before the mind, but thoughts always involve such simultaneous combination—the constituent concepts are presented as a unified contemporaneous whole. Our minds may range from one thought to another over time, more or less logically, but we don’t move from one concept to another as we cobble together a thought. We construct arguments over time, but we don’t construct thoughts over time. We don’t build a thought as we build a house—one brick after another. But we do build speech acts this way, by adding one component at a time. Thus speaking and thinking are different kinds of act, even though language is involved in both (assuming a language of thought). Utterances have beginnings, middles, and ends; but thoughts leap into existence all at once.

 

  [1] We could compare this ability to the way the brain constructs the visual field—not by painstaking construction from left to right but by massive parallel assembly. All the parts of the visual field are presented simultaneously (and produced simultaneously); it is not that we only produce one section of it at a time. So seeing is not like speaking, in which we are restricted to one sound at a time.
