Ethical Socialism

Ethical Socialism

I posed the problem of the indispensability of ethics, remarking that no ethical theory I know of has a solution to it.[1] It seems that we prize ethics above even prudence, logic, and sanity; we can’t live without it. This is puzzling—surely, you don’t have to be good to be happy! Acting ethically doesn’t always feel that great (see I. Kant, as in “I can’t help it”). I now think I have a solution to the puzzle, and it puts a particular twist on the basic rationale of ethics. I call it “ethical socialism”. The basic idea is simple and not unfamiliar: ethics is a precondition of society. Without ethics there is no such thing as society. By society I mean any social grouping: from towns and countries to families, friendships, and fleeting encounters. Any form of human association. For without ethics such collectives are impossible, since they need ethical rules in order to exist. You can’t treat someone without regard for right and wrong and expect to stay friends with them. You have to treat them right—no stealing, lying, promise-breaking, betraying, violence, and murder. Such things are not conducive to a functioning society (even of two people). This is self-evident and hardly needs arguing. What is less obvious is the alternative to a life lived with others in harmony: loneliness, isolation, misery, fear, self-sufficiency, humorlessness, poverty, early death. Nasty, brutish, short, and all alone. It sounds like hell—there is no social life in hell. The OED gives for “society”: “the aggregate of people living together in a more or less ordered community” (I love that “more or less”). No community, no communing—no chatting, sharing, amusing, informing. No one to talk to, no one to see, no one to interact with. No friend, no spouse, no partner, no helper. This is brutal stuff—the stuff of nightmares. But that’s what you get if you spurn morality. This is why the professional criminal (wrong-doer) is never completely amoral or immoral: because if he is, he has nobody, nothing. His life is barren and empty. Thus, he treats his gang and family well. He isn’t a shit to everybody. So, on pain of total isolation, he maintains a local morality, perhaps even accentuates it. You begin to see why morality matters more than prudence, logic, and sanity—at least you have some company if you lack those qualities. Abandoning morality altogether is choosing to live alone, and human life is a very meagre thing under such conditions; really, not worth living. We are social creatures and our happiness is largely social, perhaps entirely when you take it to the logical extreme. Life without society would be unbearable; no one ever chooses it. We find it difficult to imagine how a totally solitary animal can ever be happy; it merely survives.  Not that any animal is ever truly alone, what with mates and family. Total isolation isn’t biological. Ethics is written into our souls because social existence is; it is as deeply ingrained as our social nature. We implicitly understand from a young age that morality is necessary for social bonds; it is the glue that holds individuals together. It is what makes living together possible. We might thus announce that what is good and right is what enables and preserves society (in the broadest sense). It even includes human-animal societies: these can exist only because we treat animals with a degree of moral respect—they would run away if we didn’t. Animal ethics stems from human-animal societies. You can’t even own a dog unless you stick to moral principles. The very concept of right and wrong is bound up with the need for society. In a sense, it is tribal (but not in the narrow sense). We would all die early and live horribly if society was not possible, and morality is what makes it possible.[2]

A good ethical theory should register the connection between morality and society—and not by supposing that morality is “socially constructed”. It isn’t. But its profound hold on us is bound up with its role in creating social groups. This conception is socialist not individualist: it is a group phenomenon not an individual one. At the level of the individual morality does not exist. If we deny the existence of society, we undermine morality; we rob it of its point. We rob it of its content. The atomistic individual cannot be a moral agent; he can at best be a member of an aggregate. Ethics and community go together, but not ethics and the isolated individual. Thus, we might label the theory under consideration “communist ethics” or “ethical communism”. It is the ethical basis of political socialism and communism (no matter how perverted such ideas have become historically). Ethics must be directed at communities not individuals (here there is only prudence). I think this is why there has always been some disquiet over utilitarian ethics: society is not visible in it. All we get is maximizing the happiness of the greatest number, whether or not this number comprises a society (people “living together”). The beneficiaries of the utilitarian calculation could be isolated individuals. There doesn’t seem to be anything essentially social in this ethical theory. By contrast, deontological theories explicitly record interpersonal relations—don’t lie, don’t break your promises, don’t steal, don’t be ungrateful, don’t kill, clean up after yourself. It is about one’s duties to others not just making everyone feel good. Where is the interpersonal element—the I and thou? Nor should we neglect the spiritual aspect: the meeting of minds, the empathy, the spiritual communing. All this is immensely valuable to us—and it goes beyond supplying goods and services and simply getting along with each other. Our greatest happiness lies here. So, morality exists in the human species because we have interpersonal spiritual needs. In short, we need love—to give it and receive it. We don’t just want to go about our business, lovelessly. We sense that without morality this good would be unavailable to us (we might just get stabbed in the back, betrayed, enslaved). There has to be trust, or else everyone suspects everyone and bonds are never formed. We would hardly exist as human beings unless we had a developed social life, and morality is what makes this possible. Ethics is existential. Human life has no meaning lived alone. Aloneness can lead to suicide in extreme cases. So, ethics is what gives life meaning, because it enables the social dimension. It prevents life being unpleasant, isolated, and brief (what with suicide and everything). Even street-gang life is preferable to that.

We should really divide philosophy into two parts: philosophy of the individual and philosophy of the group. In the first part we deal with such problems as the mind-body problem, the problem of free will, the classical problems of epistemology, etc. In the second part we deal with ethics, political philosophy, the analysis of social facts, and some of the philosophy of language. A theorem of this branch of philosophy might be that there can be no social facts without ethical facts: societies can’t exist without firm ethical foundations (ethical subjectivism won’t cut it). Ethical nihilism produces rampant individualism and the collapse of organized society (just roving gangs and lone assassins). We have the individual-community problem as we have the mind-body problem. Some philosophers specialize in individual philosophy and some specialize in group philosophy (same in psychology). Some suggest that what looks like an individual problem is really a group problem—as with community theories of meaning or mental content. Some maintain that the concept of freedom is individualistic (a matter of causal determination) while others argue that it is a social concept (not being coerced by others). I think this is a useful division, and I place ethics on the group side. It turns out that the reason we are so firmly committed to ethics is that we are essentially and unavoidably social—but not necessarily prudent or logical or sane. We can live without the latter three, but we can’t live without society. Other people may be hell, as Sartre suggested, but it is a hell we would prefer to the heaven of total aloneness.[3]

[1] See my “Ethical Life”. I posed the problem one day and arrived at the present view overnight. Perhaps the solution will help to see what the problem is.

[2] The function of the law is likewise to codify the rules of interpersonal engagement; to regulate societal interactions. This is why it is connected to ethics. We have laws because without them society would disintegrate into amoral individualism—or so it is believed at this stage of human history. If ethics is the social glue, the law is the social hammer (it knocks in the nails). This is the importance of the law, for what it’s worth. The law is what enables to sleep easy at night and speak freely. It is society’s enforcer. A large amount of human effort is devoted to keeping society together, because without it, life becomes meaningless and unbearable. Family law is particularly important.

[3] I can’t refrain from mentioning the song, by Celine Dion and others, entitled “Alone”. The theme is the isolated individual versus the connected lover. The hysterical chorus has the lyrics, “Till now I always got by on my own, I never really cared until I met you”, and the song ends with two long shrieks of “Alone!”. The importance of morality is its capacity to prevent such shrieks.

A Program Delineated

A Program Delineated

I laid out the general form of a philosophical program in “Philosophy of Objective and Subjective”; here I will enumerate some instances of how this program might be pursued. Please don’t expect much beyond the suggestive and superficial, indeed list-like. The main aim will be to identify the possible subjective basis of a given concept (with the emphasis on “possible”). Generally, we look for a perceptual state or process that might serve as a subjective platform for concept creation; it isn’t the concept itself but only a preconceptual perceptual means of initiating conceptualization. An example might be the concept of necessity as represented by possible worlds: this provides the kind of perceptual representation that comes naturally to us as perceiving creatures—a kind of space populated by discrete objects. It need not be the case that necessity is such a fact; rather, it is a way of thinking that conforms to our representational preferences. It will appeal to us as an account of how things are, because it fits our natural point of view as supplied by our perceptual (visual) nature. It could exist alongside a less subjective representation that comes less naturally to us. In the case of space and time we could likewise rely on our perceptual faculties to provide a congenial foundation: how we experience these things, as opposed to how we might abstractly describe them. Similarly for the self—a kind of substance akin to the substances we routinely perceive (yet different). An exceptionally naïve individual might actually picture the self as a body within a body (a homunculus).

Logic, mathematics, and ethics pose stiffer problems of subjectivization (if I may coin such a word), but here too it isn’t hard to find subjective counterparts to them that linger in our thoughts. Thus, logical consequence might be represented as a type of psychological compulsion. The sophisticated reasoner might well officially repudiate such a conception, but that doesn’t mean it plays no psychological role; it might have been a childhood prototype for what later became the more objective concept of entailment. In mathematics it is easy to see the fingers as providing an entry point into the abstractly mathematical; we think of numbers initially as corresponding to digits (note the word). Geometry is surely initially understood by means of seeing concrete figures, and this association may linger. In the case of ethics, we may appeal to feelings of sympathy or fear of punishment; ethics surely has its earliest basis in such subjective attitudes, and may not get much beyond them in many adults. What is notable is that when the subject tries to get beyond such primitive subjective facts, he is apt to become vague and lost for words. He doesn’t quite know that whereof he speaks (a theme of empiricists like Hume). The crutches thus never get completely thrown away. It is as if we are condemned to be subjective, even against our better judgment.

What about language? Clearly, we experience it, actively and passively. It is hard to deny that this experience shapes our conception of what language is, though it doesn’t exhaust it. We have a kind of double conception of language: as we perceive it and as we think of it in the abstract (a finite system of symbols combinable into an infinity of meaningful sentences). A totally objective conception of language would be difficult to acquire and completely unnatural. Language has a phenomenology. Linguistics has both a subjective and an objective department. Psychology is much the same: we have a subjective view of our own minds as well as scientific knowledge of mind. These may compete with each other as systems of understanding. Our concept of action likewise oscillates between the subjective and objective: the point of view of the agent and the “view from nowhere” of the disinterested observer or theorist (first-person and third-person).

More technically, Strawson’s analysis of definite descriptions is more subjectively influenced than Russell’s: Strawson is impressed by how the utterance of the sentences in question strikes us, while Russell wants to know the structure of the fact considered in itself. The true justified belief analysis of knowledge takes the point of the knower more seriously than reliability theories of knowledge. Wittgenstein’s view of games is more subjectively influenced than Bernard Suits’s analysis, given that it emphasizes observable features, while Suits adopts a more abstract approach. We might say that subjectively Wittgenstein is right about the concept while objectively Suits is right. Description theories of names adopt a first-person point of view, while causal theories take an objective standpoint. We see the attractions of a given theory by adopting a subjective or objective perspective. The subjective-objective contrast runs through many a philosophical issue.[1]

[1] Of course, this idea was a main theme of Thomas Nagel’s The View from Nowhere.

Philosophy of Objective and Subjective

Philosophy of Objective and Subjective

If concepts divide into the objective and the subjective, it should be possible to conduct a survey of them and assign them accordingly. We should be able to group and rank them according to their objective or subjective character. This would be an exercise in conceptual analysis—not analysis into components but into general categories. It should be philosophically illuminating. Think of it as a philosophical project or program: discovering which concepts qualify as subjective and which objective (or possess these attributes to different degrees). How do we think of the phenomenon under consideration, objectively or subjectively? For example, how do we think of color and shape–do we think of shape objectively and color subjectively, or vice versa? What about identity and existence? Or the self. Or truth and knowledge. Do we think of these things from a specific point of view, or do we abstract away from this to obtain a more impersonal conception? Do the relevant concepts have a subjective structure or an objective structure? What kind of structures might these be? The obvious idea is that subjective concepts reflect our perceptual point of view, while objective concepts (if there are any) reflect more universal faculties (e.g., reason). Do we think of color perceptually, possibly by means of mental images, and shape by means of abstract geometry grasped by pure reason? Do we think of existence subjectively as what we perceive with our senses, or do we have a more abstract objective concept of existence that takes in numbers? Do we employ ourselves in our concepts or do we set ourselves aside and focus on the object? What is the architecture of our conceptual scheme—is it based on a foundation of subjective viewpoints or something more universal and absolute? Are we representational subjectivists or representational objectivists? And what about other animals and aliens from outer space?

We need some guidelines. I think we do well to begin with a subjectivist hypothesis: all concepts have a subjective ingredient or origin or history, even if they also possess a measure of objectivity. Concepts begin with the self and probably the perceiving self. They come from innate constitution plus experiential history. They are relative to the creature that has them. The simplest theory is that all concepts of the external world derive from sensory experience (empiricism) and hence embody a subjective perspective; look closely and you will always see perception lurking in the background. Let’s formulate this as the Special Theory of Subjective Relativity: all our concepts of empirical reality are based on perceptual subjectivity. Then we can say that all such concepts incorporate perceptual subjectivity (they are all relative to the subject’s specific mode of sensory experience). In the obvious case, they are visually based: seeing is the subjective mode under which we conceptualize things. We thus need to understand the subjectivity of seeing—how it works in the representation of objects. In what does the subjective character of seeing consist? The answer is not far to seek: vision involves fleeting and variable stimulations of the retina that are processed to produce a stable world of constant objects. It is the correction of the idiosyncrasies of the ceaselessly changing retinal image. It manufactures constancy from variability.[1] Thus, concepts incorporate this kind of corrective operation; they result from acts of proximal stimulus regulation in the direction of constancy. The variation of retinal stimulation has a phenomenological counterpart: an area of the retina corresponds to what is called “apparent size”. We need not go into the details; the essential point is that correction plays a central role in producing a picture of reality—correction of the proximal stimulus. What we can say, then, is that all concepts result from this kind of operation: subjective states that have been processed to produce something endowed with (a degree of) objectivity—as it might be, seeing a ball coming towards you and not changing in size. In the case of the concept of existence, then, the subjective dimension consists in perceptions of objects that result from operations on proximal stimulations or apparent qualities. In short, our concept of existence incorporates a perceptual process: for something to exist (for us) is for it to emerge from the chaos of sensory bombardment. This is what the Special Theory of Subjective Relativity (STSR) is telling us: it is offering a theory of the subjective make-up of the concept in question. This would be the beginning of an investigation into the subjective character of human concepts. Concepts are imbued with the kind of subjectivity characteristic of visual perception.

Methodologically, the program is like Chomsky’s program in linguistics, but where he sought to identify underlying syntactic structures, this program looks for underlying subjective structures (you could write a book called Subjective Structures). Concepts evidently have a subjective composition and we want to know precisely what that composition looks like. The current proposal is that it is perceptual in character, with the kind of structure present in visual perception (proximal stimulus, correction, constancy). The subjectivity is of a familiar pattern. But we must remember that there is also objectivity of a sort—the world does get represented more or less as it is, subject-independently. Concepts do apply to things outside the subject’s head. So, concepts have both a subjective dimension and an objective dimension; they are a mixture of the two, like a visual percept. The objective aspect is harder to analyze and I doubt that we know much about it at present (how does the mind manage to latch onto things outside of itself?). Still, we can recognize its existence, if not delineate its nature; concepts are hybrid entities, combining the subjective and the objective (like percepts). The program, then, has a dual goal: investigate the subjective and objective aspects of concepts—what they are, where they come from, how they evolved, etc. That is the basic structure of the inquiry; the details need to be filled in by future research.

It is beginning to look as if we don’t have a single concept corresponding to a given word but a duality of concepts: we conceive the same thing both subjectively and objectively. We can’t ask what is the concept of knowledge, say, because there are two concepts (possibly more): we have both a subjective concept and a (more) objective concept. One concept derives from our perceptual faculties, the other from somewhere else (language, reason?). We have experienced knowledge in ourselves and others and formed a conception of it based on that, but we also seem to have a concept of knowledge that extends beyond such episodes of acquaintance and whose origin is obscure. These paired concepts can pull in different directions, creating conceptual perplexity; they need not cohere. We have subjective conceptual analysis and objective conceptual analysis (consider space and time). The structure of our thinking is thus more complex than we supposed; our concepts are multi-leveled. It won’t be easy to excavate them, perhaps next to impossible. Maybe we can only scratch the surface. What methods can we use?  The standard approaches of cognitive science seem inadequate to the task; the computational model seems inappropriate. The idea of a language of thought is unhelpful. The cognitive mind seems intolerably complex when viewed through the subjective-objective lens. But the project looks well-defined.[2]

[1] Tyler Burge’s Origins of Objectivity contains a nice discussion of constancy directed towards philosophers, but any introductory textbook on perceptual psychology will fill you in.

[2] Part of the problem in this area is that the concepts of objectivity and subjectivity, though frequently used by philosophers, are commonly left at an intuitive level; we need to do some conceptual analysis on them.

A Paradox of Objectivity and Subjectivity

A Paradox of Objectivity and Subjectivity

We normally suppose that our thoughts concern an objective world. We are capable of thinking about things outside the mind. There is a mind-independent world and we can make cognitive contact with that world by deploying our concepts. I can form conceptions of things that exist outside my mind. Any argument that contests this assumption would be rightly deemed paradoxical. I am going to develop such an argument. I cannot cite a source for the argument to be presented, though hints of it exist in the philosophical tradition. It concerns objectivity and subjectivity. I don’t think it is obvious, though once grasped it has a kind of ineluctable logic, a disturbing inevitability. It can elicit the “Oh-my-god!” response.

I will state the argument initially in its bare bones, so that its anatomy is clear from the start. Either we conceive of the external world objectively or subjectively. If the former, we have to explain how this is possible: how do we form objective conceptions? Such a conception would have to be independent of the conceiving mind’s nature, or else it would be subjective. But this is impossible: concepts cannot be independent of the conceiving mind. So, the conception would have to be a subjective conception, i.e., dependent on the nature of the subject—his perceptions, cognitive processes, memory, rational faculties. But then, it could not concern anything outside the mind: purely subjective representations can’t be about anything objective—they can only be about the mind itself. Therefore, there cannot be a conception, objective or subjective, with an objective reference (content, subject matter). Objective conceptions are impossible, and subjective conceptions must be subjective; but these are the only two possibilities, so objective thought is impossible.

Let’s spell this out a bit. A purely objective thought would be an instance of the “absolute conception”, i.e., a conception available to any intelligent being regardless of sensory equipment or other peculiarities. It would not depend on any peculiarities of the thinker but be universal. But how is such a thing possible, given that every thinker has a specific nature? Surely, there cannot be a thinker without a cognitive structure—a way of forming concepts. The idea of a featureless bare intellect is a myth, as empty as the idea of the bare particular. Every mind has an innate structure and a course of experience; these constitute its ability to form thoughts. It cannot form thoughts from nothing. The mind evolved and obeys the rules of all biological organs: capacities constrained by internal structure. The only way the mind could achieve total objectivity would be by incorporating the objective world, letting facts act as concepts; but that is a nonsensical idea. Concepts are in the head (brain) and reflect the biological structures therein; they are not antecedent realities hovering out there somewhere. The subject is always present in his thoughts, it might be said; his thoughts cannot be separate from his nature. So, objective thoughts cannot be obtained by making certain thoughts “absolute”, since there can be no such thing. My concepts are my concepts, not the world’s.

This point may be readily conceded but insisted that it was always a misguided conceit; of course all thought is subjectively constituted. Why should that prohibit the formation of thoughts about the objective world? Why can’t we have subjective mental representations of objective facts? Here things turn subtle. The problem is that such thoughts will either contain a hidden objective component or will fail to get the mind beyond itself. I can illustrate the point by reference to Russell’s preferred account of “knowledge by description”. His idea is that the mind achieves a degree of objectivity by employing descriptions of the form “the cause of these sense-data”. The reference to sense-data gives us subjectivity, while the reference to external causation brings in the non-mental world. Isn’t this a subjective representation of an objective fact? Well, no, because of that little word “cause”: either it is intended objectively or subjectively, but the dilemma just rehearsed ruins the operative idea. If objective, then the description is not entirely subjective and raises the question of how we have a purely objective notion of cause, which runs up against the argument against objective conceptions. But—and this is the crucial point—if the word is taken subjectively, we don’t have an ingredient that takes us outside the mind. All we have is reference to “ideas”. We must be careful here: it might well be that there is an objective cause out there, and it may be that it operates as a kind of de re object of thought, but it doesn’t follow that we have a de dicto objective content (a genuine concept). So, the account either presupposes what it sets out to explain (objective content) or it fails to deliver the kind of objectivity we normally take for granted. In a slogan: no objective reference without objective content. It follows that there cannot be a purely subjective conception that achieves objective reference (intentionality). In short, all concepts are tinged with subjectivity, but subjective concepts cannot deliver objective reference. So, objective thought is impossible. That is the paradox.

It may be protested that weaker notions of objectivity can be invoked; we need not abandon the idea of objective thought completely. This would be tantamount to a skeptical solution to the paradox; and indeed, such a view is possible. We might, for example, introduce a social notion of objectivity, in which interpersonal correction takes up the burden of delivering objectivity. I won’t go into this, familiar as it is; the point I want to make is that this is a skeptical solution, since we naively suppose that our thoughts can achieve objective reference without the aid of other people. Can’t a solitary animal manage to think objective thoughts irrespective of belonging to any community? What we have discovered is that the objective-subjective polarity does in this natural naïve idea (or purports to). That is surprising: other considerations have been invoked to undermine the idea of objective reference to the external world (from Berkeley to Quine), but not the objective-subjective distinction. But these notions wreak havoc on the idea of objective thought by presenting a nasty dilemma. Either the myth of the absolute conception (never fully explained) or the impotence of the purely subjective to reach out to objective reality. The resulting position is like Kant’s: a noumenal world that exists but cannot be made an object of thought in any meaningful sense. We are confined to representing a phenomenal world shaped by our own minds.

Let’s take a step back. I believe the nub of the argument is that (fully) objective thought is impossible—that is, there can be no absolute conception. Whatever thought is, it must be something; it can’t proceed from a blank slate (whether genetic or environmental). Concepts have to consist of something in the subject (images, words in the language of thought, dispositions to behavior, etc.). In the end, the brain fixes the parameters of thought. There is no “view from nowhere”. Once this point has been absorbed, the gap between thought and reality stands forth: we always see things from our own given point of view, i.e., our cognitive psychology. We can never really bridge this gap. We function well enough in a world existing outside us, but we can’t really obtain an unvarnished picture of the world, a purely objective conception. Maybe we can approximate to it, find a workable substitute for it, but we can’t get outside our own minds completely. We can’t know world as it is in itself and only as it is in itself. We can’t see it from its point of view (the “view from elsewhere”). All living creatures are in the same boat—from vermin to Vulcans. This doesn’t mean we can’t see, know, remember, etc.; but it does mean that a certain picture we are apt to have of our cognitive powers is at best exaggerated. We don’t live in a glass house. We are not made of mirrors (except the distorting kind). The basic paradox is that objective thought is a fundamentally incoherent idea.[1]

[1] Not true thought or justified thought, but thought that is about reality as it exists in itself independently of our own constitution. We can conceive our peculiar perspective but not what it is a perspective on. That remains elusive, partly or wholly.

Objective and Subjective Knowledge

Objective and Subjective Knowledge

We must first make a firm distinction between objective and subjective facts, on the one hand, and objective and subjective conceptions of facts, on the other.[1] That is, we must distinguish the application of these terms to the world (objects, properties) from their application to mental representations of the world (perceptions, thoughts, knowledge). A subjective fact would be something like a belief or state of consciousness; a subjective conception would be a subjective representation of a fact. Thus, there can be subjective and objective conceptions of subjective facts, and similarly for objective facts. For example, there might be subjective and objective conceptions of shape, this being a type of objective fact; and there might be subjective and objective conceptions of pain, this being a type of subjective fact. I will not here be much concerned with subjective and objective facts, but rather with subjective and objective conceptions. What, then, is that distinction? Roughly, it is the distinction between representations from a particular point of view and representations that prescind from any particular point of view—that are independent of point of view. Just to fix initial intuitions, we can distinguish the point of view of a dog from that of a human, given the sensory and cognitive differences between them (smell, hearing, etc.). Each species has its own distinctive point of view—there are many types of subjective perspective—while the universe itself has only one inherent reality. Subjective conceptions are subject-relative, multiple, and idiosyncratic. By contrast, objective conceptions (if such there be) are absolute, singular, and universal. There are many subjective points of view on the same objective reality, but objective points of view converge on reality itself. We will have more to say about this distinction later; for now, I am just trying to mobilize intuitions along familiar lines. The subjective reflects the nature of the subject; the objective reflects the nature of the object. We can think of the world subjectively or we can think of it objectively (or so it seems). I want to ask which domains of knowledge fall into which category: what do we know objectively and what do we know subjectively?

We already know that we can’t read conception off from fact: an objective fact can be known objectively or subjectively, and a subjective fact can be known subjectively or objectively. It depends on the manner of knowing not on the nature of the object known. Thus, we can’t infer that physics is (conceptually) objective because it deals with (ontologically) objective facts; and we can’t infer that psychology is (conceptually) subjective because it deals with (ontologically) subjective facts. In fact, I think it is the other way about: physics is subjective and psychology is objective—or the latter is more objective than the former. The reason is that our knowledge of physics reflects our subjective modes of apprehension more than our knowledge of psychology does. The latter is less subjectively mediated than the former. This is simply because physics is known via perception, but psychology isn’t; that is, we know the nature of the subject matter of physics on the basis of our sensory evidence, whereas we know the nature of the subject matter of psychology non-perceptually. Mainly we know physics via vision, but we don’t know the natural kinds of psychology by seeing them; we know it introspectively or “intuitively”. Our conception of the mental is thus closer to its intrinsic nature, and hence more objective (object-centered). This is implicit in traditional epistemology, particularly empiricism, because of the doctrine that knowledge is derived from sense experience. The content of physical theories is supposed to derive from the character of sensory experience, especially visual experience. But vision is par excellence subjective, i.e., relative to the perceiver; it is the original home of perspective. How the world is seen and perceived generally is relative to the species in question. So, the physical world will be apprehended via sensory experience, which is to say subjectively (“the cause of these experiences”). At the least our grasp of physics will be subjectively infused, from the very large to the very small. This is a familiar observation, which need not be labored. The interesting point is that the same thing is not true of our knowledge of psychology: our grasp of the nature of mind is not visually mediated; it is more an example of direct objective knowledge. We know just what pain is, objectively, not merely how it sensorily seems to us. We immediately apprehend its essence, to put it in old-fashioned language. Consequently, psychology contains more objective content than physics; it is less subjective. Its conceptions are less subject-dependent, idiosyncratic, species-relative (consider what an intelligent dog’s physics would be like). Aliens with radically different senses from ours would conceive the physical world differently from us, but they would have much the same conception of the contents of minds (assuming objective psychological constancy). Pain seems the same to anyone who has it, but motion seems different according to one’s mode of perception of it (consider a blind animal).

I now want to put forward a bold conjecture: a priori knowledge in general is more objective than a posteriori knowledge. The reason is clear: a posteriori knowledge is sense-dependent while a priori knowledge is not. The former is “based on experience”, but experience varies from subject to subject; while the latter is not so based and hence not so variable. I mean to include logic, mathematics, and ethics: these are characterized by an absence of sensory foundation, and therefore do not partake of the subjectivity of the sensory. In a sense, our knowledge of them is more direct, less mediated by perception, and hence less beholden to the varieties of sense experience. Our conceptions of the a priori will have more in common with those of alien subjects precisely because they are not based on perceptual experience. You can vary the senses but leave the a priori intact conceptually. Thus, ethics is more objective than physics in the sense explained (there may be other senses in which it is less objective). Logic, for its part, is manifestly more objective than physics (or chemistry, geology, astronomy, etc.), precisely because its epistemology is not dependent on the senses; we don’t think of entailment visually. Of course, physics and astronomy were once highly subjective in that motion was taken as relative to the stationary earth, because of our naive perception of it; but it is also hard to deny that our picture of the physical world is determined by our perception of it. This is not true of logic or mathematics or ethics. The a priori stands above the senses, or apart from them; the a posteriori, by contrast, is up to its neck in perceptual subjectivity. Accordingly, the objective facts of physics are conceived subjectively, at least in part, while the a priori sciences are proudly objective in their mode of conception. The concept of gravity, as we have it, is more subjective than the concept of logical entailment, say. Folk physics is more subjective than folk logic (or folk ethics); and the same may be said of more professional brands of physics, these being rooted in folk conceptions. Phenomenology too is more objective than physics in the intended sense, because of its freedom from the tyranny of the visual. Physics is skewed in a way the a priori sciences are not (including phenomenology).[2]

[1] For background the reader should consult Thomas Nagel’s discussion of objective and subjective in The View from Nowhere, chapter 1.

[2] I take this point to belong to that peculiar philosophical genus, the shocking truism. Physics is perhaps the most subjective of all subjects!

Brain Specialization and Cognitive Closure

Brain Specialization and Cognitive Closure

Is the human brain intellectually limited? How limited might it be? Is it also limited emotionally and athletically and artistically? Suppose we ask the same question about the parts of the brain, the various functional structures gathered into a single brain—are they limited? For example, can the visual cortex perform all possible mental tasks—seeing everything, knowing everything, feeling everything? Obviously not: it is a specialized organ dedicated to certain specific tasks—seeing in general and seeing what this organism needs it to see. It is by no mean omnicompetent. Why on earth would it be? It is no more omnicompetent than the heart: this organ has the function of pumping blood around the animal’s body—not the function of pumping any old thing and certainly not performing non-pumping tasks. The same is obviously true of other brain parts (and body parts): they do a specific job and not any job you might come up with. They are like the parts of any machine—special purpose devices designed to do one sort of thing and not another. You put them all together and you get a functioning organism. No one would ever think the hypothalamus can do everything.

It is much the same with the two cerebral hemispheres, notoriously so. They have specialized functions, distinct identities or “personalities”. The left hemisphere, we are told, specializes in language, logic, motor control of the right side of the body, and the ability to focus; the right hemisphere is said to handle creativity, spatial skills, emotions, motor control of the left side of the body, and metaphor. The empirical facts are somewhat cloudy but the general picture is plausible enough: the brain in general tends to specialize according to area. There is lateralization of function as well as location of function. Accordingly, we don’t expect the left hemisphere to be able to do what the right hemisphere can do or vice versa (despite a degree of plasticity). One would expect cognitive (and other) closure with respect to the two hemispheres of the brain. Would anyone claim that the right hemisphere has the equipment to solve the mind-body problem, say? Then why does it seem reasonable to insist that the two limited hemispheres together could solve all problems? How can two limited things combine to produce an unlimited thing?

What is the function of the human brain? The same as the function of any animal’s brain—to aid survival. We need not think of this in a brutish primitive way—by all means include happiness and intellectual inquiry (worthwhile survival). The point is that each species has a specific lifestyle, with a distinctive type of body and reproductive procedure. We are bipedal and social; other animals are not.  There is no reason to believe that we, or any other known species, possess some sort of all-purpose brain power. We don’t possess an all-purpose body capable of any action and equipped for any environment. On the contrary, bodies are specialized according to their survival requirements—very specialized. The brain (mind) is really no different; it has its scope and limits. What would be the point of equipping it to do things it will never be called upon to do? Just think how impractical such a design might be. Organisms must economize not waste resources on quixotic ventures. The parts of the body and brain are thus specialized and the brain itself is an organ that obeys the same laws. You don’t need a heart that will pump up tires and you don’t need a brain that will pump out answers to any conceivable question. Such a thing is surplus to requirements, to put it mildly. Cognitive closure follows from the basic laws of biology.

Here is another way to conceptualize the point. The genes are very simple beings with only one thing on their little gene minds: survival. They build bodies that serve their limited purposes (no one thinks the genes could solve the mind-body problem!). The bodies they build contain organs that serve their purposes, including brains. Don’t expect these brains to be designed so as to solve any problem the universe throws at them. The genes would never make brains like that. Brains operate under tight constraints. The selfish gene is an intellectually limited gene. Not the dumb gene exactly, but certainly the austere and miserly gene. It’s amazing brains are as clever as they are.

Humanistic Zoology

It is possible to describe humankind in the objective terms favored by orthodox zoology and biology. You can describe the human being in scrupulously behavioral terms, stressing his anatomy, physiology, and evolution. It can be quite illuminating to do so, and not untrue. For example, you can describe human sexuality this way (Desmond Morris does an excellent job of this in chapter 2 of The Naked Ape). This is the scientific approach and we are sternly warned that we humans are subject to it as much as anything else in nature. But all the while we are aware of the inner world of our species, because it is us and we know ourselves from the inside. We protest: the objective scientific picture is not the whole truth. There are subjective descriptions as well, also true. Sometimes this is dismissed by traditional zoologists—as just so much waffle and tripe. Maybe we will one day get beyond it. But it is also sometimes taken to reflect our specialness: we alone have these two sides; we have a dual nature, a double life. But other animals don’t, or only a very minimal one. If we are being objective, animals are just what is revealed from the “scientific” perspective; and no one protests, because we are not those animals. They can’t protest: “We are more than your science allows!” The point I want to make is that there is a fallacy in all this: for it is not objective to limit oneself to “objective facts” such as behavior and physiology; it is subjective. Why? Because it privileges the human viewpoint—the way we see things. It does not respect objective reality. We have a subjective perspective on other animals, determined by our perceptual, cognitive, and imaginative faculties; but there is a reality about them that we perceive only dimly, if at all. That reality exists in the objective world, whether we can get to it or not (and we often can’t). It might be described as a subjective reality, but it is still an objective fact. Behaviorism is not objective but subjective: it contains our point of view not reality as it exists independently of us. The so-called scientific point of view is not really objective at all. It denies, or neglects, the reality of the zoological world.

Thus, I aim to promote a “humanistic zoology”. Just as we can have a humanistic study of man, so we can have a humanistic study of beast—a study that recognizes and respects the inner life of animals of other species. Of course, the idea is not to humanize other animals—to see ourselves in them. It is to see them as they are in their full reality. This is difficult because we don’t know them from the inside, as we know ourselves. We know very little about what it is like to live the life of a lion, say. We try to imagine it, but we don’t get very far. Still, we should try to gain what insight we can for the sake of the science (let alone the ethics). Let’s not define (and confine) science in terms of our own make-up and limitations; science is about objective reality not about reality as we see it. Zoologists should write books about the inner life of the hyena or kangaroo—psycho-zoological books. There should be departments of humanistic zoology. I think it could be very interesting (Jane Goodall would have had a lot to say). Richard Dawkins should step in (The Unselfish Rat). Don’t leave it to writers of children’s fiction; get scientific about it. I volunteer to take on the butterfly.1 Please don’t say that “humanistic zoology” is a contradiction in terms; it doesn’t mean “anthropocentric zoology”. It means something like “respecting the lived reality of a creature, human or other”.
