Abstract (and Other) Objects

Abstract (and Other) Objects

I propose to discuss an incredibly difficult question and to suggest an incredible answer to it—an answer that only ineluctable logic could recommend to our modern sensibility. It concerns the threefold distinction between the physical, the mental, and the abstract. Let’s first try to get the abstract in our sights (this is hard enough), starting with the OED: the adjective “abstract” is defined as “theoretical rather than physical or concrete”, and “derived, extracted”. Thus, the abstract is defined by contrast with the physical or concrete, and implies an operation of derivation or extraction. We may gloss this as: “derived or extracted from something physical or concrete”. This corresponds with the idea of abstraction as a mental act—the abstract is what is derived byintellectual abstraction. It is thus something secondary, dependent—both ontologically and epistemically. The abstract object depends for its existence and nature on the concrete object from which it is an abstraction, and we acquire the concept of the abstract object by a mental act of abstraction. For example, the number 2 depends on the (concrete) objects so numbered, and we have the concept 2 by a mental act of abstraction (derivation, extraction). This is clearly not the notion of the abstract entertained by Pythagoras and Plato (and Frege and Godel); they viewed abstract objects as primary existences—as more real than concrete perceptible objects, or at least equally real. If anything, Pythagoras and Plato viewed the concrete as dependent on the abstract, ontologically and epistemically. And there have been plenty of mathematicians who would endorse this picture—for them, mathematical objects are directly apprehended and depend for their existence on nothing else. So, the dictionary definition is quite wrong as far they are concerned; or rather, they would demur from describing numbers etc. as “abstract” in the dictionary sense. They would choose to describe them in other terms—as Plato described them as Forms. In truth, it is hard to find satisfactory language for the doctrine in question—quite possibly because the conception is hard to pin down. The concept tends to be defined negatively, by contrast with “physical” or “mental”. If we imagine alien thinkers who are natural-born Pythagorean Platonists, but shaky on the mental and the physical, we might suppose them to have a robust ontology of the “abstract” (while not using that term), and only negative definitions of the mental and physical (what is not what mathematical objects are). In any case, our definition of the abstract would not be natural to them, and is conceptually lacking in our own case. But let’s suppose such entities to exist in whatever sense Pythagoras and Plato supposed, as autonomous, independent constituents of reality, even if we find it difficult to get a conceptual-linguistic handle on them. What, then, about the other two categories—are they properly defined?

Here the situation is not much better than with the concept of the abstract: neither concept is clearly defined. The concept of the “physical” is hopelessly undefined; this is a familiar story that I won’t repeat. The OED gives us “relating to the body as opposed to the mind”. That is about the best we are going to get, but everything hangs on the word “mind”: do pain and other bodily sensations relate to the mind or the body? Surely, the body, but they are usually classified as mental by theorists. What about the senses, particularly touch? The body, of course. Thought relates to the mind, but most of what we habitually call “mental” today does not. I would say that all of the mind relates to the body, particularly the brain, as opposed to some supposed immaterial entity (the “soul”); so, the mind is all physical, according to the dictionary. So be it: let the mind be physical in that sense—the distinction then vanishes. Nor is the concept of the mental well-defined: are character traits mental, or the unconscious, or skills, or language? There is no “criterion of the mental”. Both concepts are ill-defined, virtually meaningless. I think they should be abandoned in theoretical taxonomic contexts; they are obsolete holdovers from religious doctrines of the soul and immortality. The body and brain have various kinds of attributes—that’s all we need to say.[1] From the point of view of nature, no deep ontological division exists; there is no natural kind consisting of all and only (so-called) mental things. Nor is there a natural kind of (so-called) physical things. We could instead speak simply of organic and inorganic and give up on the (metaphysical) mental-physical distinction. This is a Spinoza-like position: the body has the power to produce all the attributes we and other animals possess, including consciousness—there is just one substance. It is also Darwinian: everything evolves by natural selection acting on the body. There is no separate soul, no supernatural basis for the mind. Accordingly, the traditional threefold distinction is defective beyond repair: each concept is deeply flawed and should not be used to shape our considered ontology. We need a new taxonomic scheme.

So, what would the new and improved ontology look like? Granted we accept the reality of mathematical objects, it will be a dualist ontology: Forms and Bodies, basically. We will have geometry and arithmetic on the one hand and organic and inorganic bodies on the other. Simplifying, we have material things and immaterial things—Forms not being material. Spinoza plus Plato. There is no Cartesian dualism, but there is a Platonic dualism. There is no Mind-Body dualism, but there is a Body-Form dualism. This means that the problems of dualism will carry over to the new dualism: how exactly are the two spheres of reality related? We can envisage a familiar array of options: attempts to reduce one sphere to the other, eliminative positions, and interaction problems (Plato was already aware of these). The two realms have quite different natures (they are different metaphysical natural kinds) yet they come together, because mathematics applies to the natural world. None of this means that the so-called mind-body problem will disappear; but it does mean that we cannot frame it in the post-Cartesian (pre-Darwinian) style. Trying to conceptualize this new dualism will not be easy, because we don’t have concepts naturally suited to the task, particularly concepts of the “abstract”. There is much here that is “wide open and extremely confusing”.[2] Bodies are spatiotemporal but Forms are not; bodies change and evolve but not Forms; bodies can be perceived via the senses but Forms cannot. Could we get by with an ontology of bodies and sets of bodies? Can our current conceptual scheme take the strain? Could there be a deeper unity that encompasses both? Could bodies have tiny Forms in them that combine to create larger Forms (“pan-Formism”)? Are some things intrinsically more mathematical than others? Are bodies appearances of Forms? Is it possible to be an idealist about Forms? Is the philosophy of mathematics really the most basic area of philosophy (the “mathematical turn”)? Is the concept of body inescapably anthropocentric? Is the Body-Form problem soluble? Is there anything it’s like to be a number?[3]Does the brain have a hidden mathematical essence? And so on.[4]

[1] We can certainly raise questions about the relation between these attributes (say, consciousness and neural states), but we won’t be treating these attributes as “mental” in some inclusive sense (Wittgenstein would approve).

[2] I am quoting Kripke.

[3] This may seem like a wild question, but is it any wilder than asking the same question about atoms? If numbers are real constituents of reality that enter into bodily facts (including facts about conscious experience), then we can envisage a metaphysics that seriously ponders the question.

[4] Much of metaphysics has centered around the relation between the “mental” and the “physical”, poorly defined as those words are (religion surely comes into this). According to the new dispensation, Plato’s metaphysics replaces this preoccupation: we really should be concerned with the relation between the Formal (mathematical, logical, moral, aesthetic, universal) and the Bodily (spatial, perceptible, concrete, evolving, particular). It won’t be easy to make this switch. This is why I said that the answer I am sketching is incredible (to us, now). But these are early days. Who knows what philosophical convulsions might lie in wait for us?

Explaining Trump

Explaining Trump

I think I have finally solved the mystery of Trump—the mystery of his popularity. I used to think it was his overt racism: what else could it be? But that was just one manifestation of his underlying appeal. The real reason is that he is a rich asshole, and is perceived as such. He is thus what many people (most people?) desire to be—rich and an asshole. Of course, people want to be rich—that’s just human nature. But one aspect of that is that you are then free to be an asshole—to abuse, insult, and mistreat people. You don’t have to be moral! You don’t have to have good manners, common decency, generous feelings—you can unleash your inner asshole. Hence all the talk of Trump’s “authenticity”—he is everything his supporters wish they could be. He looks down on almost everybody for being poorer than him and less of a “winner”. It also helps that he is an ignoramus, uneducated, illiterate, unsophisticated, a philistine: he proves to people that you don’t need to read books or have a good education in order to be successful. He is highly enviable—rich, nasty, and dumb. It’s a very appealing combination. In addition, he is moderately handsome and smartly dressed, also tall. He is what every American man longs to be and every American woman fancies (note my Trumpian use of “every”). But these are peripheral traits; the essence is the rich assholery. People don’t dislike this; they love it. And it gave him the presidency twice, so it must be good. He is the American dream personified. So, bear this in mind as you watch his inauguration tomorrow.

How Not to Talk Garbage

How Not to Talk Garbage

There is a new type of speech act in the marketplace—the talking of garbage. Philosophers and others have identified several species of defective speech act: falsehood, lies, nonsense, bullshit, hate speech, etc. Each of these needs careful study, and has received it. But speech garbage is in a class of its own, and it is on the rise. What is it? The first point is that it is not easy to say; this allows it to pass unnoticed and to prosper. Roughly, it is a mixture of falsehood, bias, innuendo, confusion, and tendentious ambiguity. You know it when you hear it. Trump is the master of it, if it’s possible to be a master of garbage. It isn’t trash talk, though it may include trash talk. It’s like shoddy, defective, badly made clothes: it masquerades as quality stuff but will fall apart as soon you put it on. It may be shiny but really it’s shitty. It is irredeemable. Quantifier ambiguity is a sure sign of it: not being clear how many things are said to be thus and so. Do you mean some or do you mean all? As in: “People are saying…” or “They are murderers, rapists, and drug dealers”. Grievance is never far from it. It is always false, but slyly so. It is important that it be complete rubbish—it belongs in a linguistic trash can. It stinks. It isn’t just wrong; it is meant to be wrong. Politicians produce a lot of it, especially on the right; but university administrators (a type of politician) are also prone to it. It is manipulative, dishonest, often rife with buzz words and memes (“diverse”, “safe”, “toxic”, “woke”). The only way to deal with it is to call it what it is, but this violates social norms of politeness and hence is discouraged.

But how is it to be avoided? How does one not talk garbage? Now that is a difficult question, because it isn’t always obvious what is garbage and what isn’t. The essential point is that garbage is generally intended to promote someone’s interests over someone else’s—where the promotion is unjust. It denigrates some and elevates others—unfairly. But this requires us to know what is fair and unfair, just and unjust. We need to know the facts and appreciate the moral situation. This is why linguistic garbage is so hard to root out. It trades on ignorance in the audience, not always culpable ignorance. It is why fact checkers are important. Absent fact checkers, discourse is apt to turn to garbage quickly. Other than that, we have to resort to immediate signs of garbage talk—overconfident tall-tales, unproven theories, omissions, oversimplifications. The garbage-talker is invariably someone who resists cross-examination; he or she won’t answer questions. The thing with garbage is that it is easily exposed as garbage, so it is necessary to keep away from rational scrutiny; it thrives on lack of time to probe and question. The garbage talker tends to run away when the questions start coming. But it isn’t easy to combat it, which is why it is in the ascendant—shamelessly, unstoppably. At least we can name it and recognize its occurrence. The phrase “talking points” performs a useful service in alerting us to a certain sort of verbal activity; likewise, the phrase “garbage speech” can alert us to a type of speech act that is becoming increasingly common and is too much tolerated (“Everyone must have their say”). I recommend using the phrase as often as possible (compare “word salad”). But beware of being guilty of it yourself.[1]

[1] The words “Am I talking garbage?” should always be on your mind.

Brain Design and the Mind-Body Problem

Brain Design and the Mind-Body Problem

If you look at any organ of an animal body, you will find two things: a function for the organ and a design suited to that function. The organ’s design enables it to perform its function. That’s how nature works and it is hard to see how it could not work that way. For example, teeth have the function of chewing up food (inter alia) and they are designed to be sharp and hard—perfectly suited for their job in life. The heart has the function of circulating the blood and it is designed as a pump. The stomach functions to digest food and it has a design that enables it to do so (digestive juices etc.). We never find an organ that lacks a function, or has one but is not designed to carry it out. That would be a funny way for nature to work, especially the part of it known as evolution (it would be very un-Darwinian). In the case of the brain, we can say that the function of the brain is to think or experience or produce consciousness—to be the organ of mind. It has other functions too, relating to bodily regulation (homeostasis etc.), but chief among its functions is its role in generating and controlling the mind. To be brief, I will say that the function of the brain (part of it anyway) is to think—where thinking has further functions in the animal’s life. This is what the brain is for—why it evolved in its present form to begin with. And clearly it performs this function, adequately or excellently; it is good at controlling and producing the mind. It is expert at the management of pain sensations, for example; it is not incompetent or badly put together for that purpose. Why? Because it was designed to do the job in question (by natural selection, as we now know). If we knew that the brain had been designed with that purpose in mind by an intelligent designer, we wouldn’t doubt the excellence of its design—at least as good as the design of the eye. Examining it, we would expect to find evidence of its design excellence—suitable parts, processes, engineering principles. We would expect to find a functioning mind machine (it might not be “physical”).[1] We would examine it and say, “Yes, exquisitely designed for its purpose—just look at the way the machine carries out its appointed task”. It would be like looking under the hood of a Rolls-Royce or inside a cell phone. We would not expect to find something structureless, amorphous, unsuited for its apparent function. We would expect a design-function fitsuch that you could infer the one from the other, or at least not to be surprised at the apparent lack of fit.

But that is exactly what we do not find: form and function seem miles apart. It’s a bit like opening up the head to find only a bucket of sand—what has this got to do with that? How do the biological cells we call neurons form a design that enables the brain to serve as the organ of consciousness? What has the anatomy of the neurons got to do with thought and feeling? They are much like other cells of the body, and they form a network that does not portend what they are supposedly designed to do. For a mind-machine, they seem spectacularly poorly designed—there is not a chance in hell that they could generate mind as we know it. So it appears anyway. Yet they must have a workable design, since the brain does in fact perform the function in question. This, ladies and gentlemen, is the mind-body problem: the problem of finding an intelligible relation between the mind and the body (brain). We might call it the “brain design problem” or just the “design problem”. And the problem is that we have absolutely no idea what the design might be—how the brain might be constructed so as to perform its function. What we see before us gives us no clue as to what this design might be, and indeed seems to preclude the brain from instantiating such a design. Let’s consider what kind of design might occur to us independently of knowing the actual contents of the head. First, we would suppose that a machine for a mind would have to be composed of similar things to the mind—things like thoughts and sensations. If you want to construct an entity that thinks, you had better start with thought-like components—not with chemicals (they don’t generally issue in thinking devices). So, the “brain” needs to consist of mind-like elements—but it doesn’t. What about mental processes? Processes like inference seem remote from brain processes: electro-chemical propagation along a neve fiber is nothing like logical inference—a conscious rational process. Belief formation is nothing like a pattern of neural excitation. The gap between the electro-chemical brain and the rational mind is enormous, so we can’t find the design of the latter in in the former. Nor will the idea of immateriality help: it’s hard to think of any design that could enable a machine, material or immaterial, to think and feel. Is the brain, then, not a machine, like the heart or the teeth or the kidneys, but something else entirely—which still has a design? But what could have a design and not be a machine in the intended sense? That is, what could have a structure and composition suited to achieve a certain end and yet have no design to that end? The brain must have a design that suits it to managing the mind, but that design is invisible and scarcely imaginable. On the face of it the brain is not designed to engender the mind—and yet it does. That is the mind-body problem—the invisible design problem.

We should note that none of the standard positions on the mind-body problem even addresses the problem as so-conceived. Dualism says nothing about the design of the immaterial substance supposedly at the root of the mind, and a fortiori about the brain as correlated with the mind. Materialism simply proposes an identity or reduction without enquiring into design features of the material brain: it says that pain is C-fiber firing, but it doesn’t tell us how C-fiber is designed so as to enable it to function as pain, phenomenologically speaking? You could be a sand materialist holding that mental phenomena are identical to collocations of sand—but what is it about sand that suits it to function mentally? This point applies to both token and type identity theories–they are simply silent on the design question. Functionalism might claim at least to address the question by suggesting that mental states are holistic causal roles and brains are designed to manifest such causal roles (interconnected neurons arranged in net-like structures—“neural nets”). But the causal roles being invoked here are as different as chalk and cheese, and anyway the mind is not reducible to causal roles. The classical answers to the mind-body problem are simply sidestepping the really difficult problem, namely what kind of design the brain has that enables it to discharge its allotted function. As far as I can see, only the brain presents such a problem—no other organ in nature is similarly inscrutable. Even DNA has a design that makes its functions intelligible (embryogenesis, heredity). The brain is unique in having a function that defies explanation in terms of its design. Whether made by evolution or intelligent design, we draw a blank trying to elucidate its design features qua mind-machine. Please don’t say that computers are designed to have minds in virtue of their informational-computational properties: such properties are a far cry from the conscious mind as we know it, as has often been pointed out. The plain fact is that don’t know the mind-making design of the brain, and may never know.

Is there any way out of the mysterious-design predicament? Yes, if you have prodigious bullet-biting proclivities: you could say that the mind does not have any properties that fail to be designed for in the brain as currently conceived. The brain has an electro-chemical design, suiting it to bodily regulation and the like, and there is really no more to the mind than that—anything else is illusion, myth, fantasy. That is, you could go eliminative. No thanks, I say. Or you might try to pump up the brain with unusual fancy properties—as with panpsychism. You might try saying that the brain incorporates postulated micro-mental properties that are built into a design plan that can in principle produce the mind as we know it. This would require a type of design that has hitherto been unspecified, and of course it presupposes panpsychist metaphysics. The point I am making is that any such hypothesis must face the design question: how do you design a machine (an organ) that can exploit micro-mental properties in a device that performs mental functions? This is a condition of adequacy on purported solutions to the mind-body problem: it must fill the design gap. It can’t just be ontological (monism, dualism, etc.); it must be design-specific. You can’t solve the blood circulation problem by simply declaring that the organ responsible is the heart (that organ); you have to say that the heart circulates the blood by being a pump. Similarly, you can’t solve the mind-body problem by declaring that the mind simply is the brain; you have to say what it is about the brain that enables it to generate a mind—it does so by being a what? Here is where things get difficult, vertiginous, truly mysterious. For nothing comes to mind: not an extended substance, not a biological entity, not an electro-chemical factory, not an information-processing plant, not a home for stray particles of mentality, not a steam room of peculiar vapors. The brain doesn’t have the design of anything we know or can conceive; it must therefore have a very special kind of design that is hidden from us. This fact in itself is hard to get one’s mind around. How could the brain be so special? This is the hard heart of the mind-body problem—what gives the brain this remarkable power.[2]

[1] The OED defines “machine” as “a structure of any kind, material or immaterial; something constructed”, and also “the human or animal frame”; there is no commitment to a mechanical-physical conception of machine. The same goes for the word “machinery”: it too has a very elastic use. So, there is nothing question-begging about describing the brain as a machine for managing the mind. The intuitive idea is that of a system of coordinated elements that functions effectively to give rise to the mind and its operations—the skeleton (“frame”) of the mind, as it were. Its nuts and bolts, its basic plan, its deep architecture.

[2] When I talked about property P in “Can We Solve the Mind-Body Problem?” I tacitly assumed that P is a design property—it is designed to do a certain job. Being a pump is the property P for the heart, but we have nothing analogous for the brain and consciousness. Yet it must be there on pain of postulating miracles. Nature works by containing designs—of molecules, cells, organs, bodies, minds. We need a design metaphysics.

Book Reviews

Book Reviews

I used to write a lot of book reviews—something like 80 of them over a 35-year period. I was known for it. I reviewed in all the best places. You might suppose I must have enjoyed doing it. I did not. It was hard work and not in a particularly good way. You have to come to grips with another author’s work and provide a fair and accurate assessment of it, often suitable for a general audience. Every author you review is a potential enemy, because nobody likes to be criticized, and no book is perfect. I was always relieved when I could write a positive review, even if I had quibbles here and there. But above all it was the time and effort: it distracted me from my own work. It wasn’t what I spontaneously wanted to work on. But it seemed to me like a valuable thing to do—a service to the community, that kind of thing. Many of my reviews had untoward consequences for me (I won’t name names). The reviewee often supposed I must have some sort of personal grievance against him or her, or that I had an ideological axe to grind, or that I was just a mean bastard. None of this was true, but try telling them that. I don’t doubt that I made many enemies, and it was neither fun nor lucrative. Above all, it was counterproductive to my own work; I often wondered if I should simply give it up. But it’s hard to say no to the New York Review of Books.

But during the last 10 years I have done virtually no reviewing. It has changed my life, because in the old days I was always occupied with some review or other. Now I can concentrate on my own work. And what a liberation it is! The luxury of pursuing my own thoughts every day instead of trying figure out someone else’s! I don’t even have to satisfy some editor or other, with their cuts and suggestions (you can’t even imagine). It wasn’t my choice, but it worked to my benefit. It makes me think I should have given up reviewing earlier. Farewell book reviewing, and good riddance!

How Well Understood is Motion?

How Well Understood is Motion?

Not very. It seems to be generally assumed that we have motion under intellectual control, even if once it was quite a mystery. Physics has tamed it. Consciousness is still untamed, it is agreed, but motion is a bright spot in our understanding of nature. But I think the truth is that we have stopped worrying about what we don’t understand about motion; we just accept the gaps in our knowledge as inevitable. We are de facto motion mysterians. I don’t believe the debate about the relativity or absoluteness of motion was ever satisfactorily resolved; instead, a general positivism has been invoked. So, this basic question about motion remains unsettled. But do we have adequate predictive theories about motion—do we know the laws of motion? We must distinguish three natural kinds of motion: inanimate motion, animate motion, and intelligent motion. By the first I mean the kind of motion studied by Galileo and Newton—what is sometimes called “impressed motion”: bodies moving through space under the influence of a force–planets, projectiles, whole galaxies. Here the problem is that we don’t really understand gravity (and the same goes for the so-called electromagnetic force): for we don’t know the mechanism of gravity. It acts over space but apparently without employing any sort of medium or intelligible machinery. If you depress the gas pedal in your car, a mechanism is activated that converts this into a means of acceleration—what we call an engine. If there were no such engine, but just empty space, we would be rightly baffled—how could the pedal alone have such momentous effects? But that’s exactly what happens with gravity—massive effects but no mediating mechanism, just empty space. Hence the postulation of an ether to act as some sort of vaporous mechanism. This is an old story that I will not belabor. It is as pressing and baffling now as it ever was (despite Einstein’s invocation of “curved space” and such curiosities). And why should matter give rise to this force (ditto the electromagnetic force)? It just seems pasted on, superadded (like icing on a cake). What have extension, solidity, and mass got to do with an attractive force? Couldn’t matter exist and give rise to no such force? Isn’t this at least conceivable? Evidently, gravity exists, whatever it is exactly, but we don’t know how it comes to exist (rather like consciousness, in fact). So, we don’t know how massive bodies produce motion in other bodies, often separated by great distances. We know the laws, but we don’t know the means (as Newton notoriously admitted). And what is a force anyway? It isn’t matter but it isn’t empty space either, but something in between—invisible, impalpable, ghostly. No wonder some physicists (e.g., Hertz) have tried to dispense with forces—they just aren’t physical. But all motion is supposed to depend on them. We are hardly swimming in a sea of transparency here; we are wallowing in a murky pool of obscurity. But we have wallowed in it long enough not to notice anymore. And all this is before we get to the puzzles of quantum theory, in which the very idea of a moving object comes into question, along with its position in space. Inanimate motion is thus not a safe space for intellectual comprehension, despite the scientific advances of the last few centuries. In point of fact, we don’t really know why or how the universe moves at all, as opposed to sitting still all the time; it just does, powered by forces that seem inexplicable. You could be forgiven for supposing that motion is just one giant mystery at the heart of the universe (the position of our intellectual ancestors).

Then we have the motion of organisms. These motions are not even recognized in physical theories of inanimate motion; they go beyond anything that existed before life evolved (straight lines, ellipses). They are naturally conceived as self-generated not impressed from outside; they are functional, goal-directed. This applies even to plants and single-celled organisms. Such motions appear emergent, not prefigured in the simple motions of planets and projectiles. They have internal causes of some sort, but we don’t really have a science of how these causes lead to the motions we observe: we don’t have laws of animate motion comparable to the laws of inanimate motion. There is no Principia Biologica to be set beside Newton’s great book. There are no mathematical equations of organic motion. Still less do we have a science of intelligent motion—rational, deliberate, creative motion. The motions involved in language use, say, do not follow from Newton’s laws of motion—or not in any way we can use. The mind produces motion, but not in the way material bodies do. We call this type of motion “behavior” to distinguish it from inanimate motion, thereby acknowledging a difference of natural kind—motion under the force of intelligence, so to speak. You can’t predict the motion of human bodies from Newton’s laws, though they apply to the particles that compose human bodies; rational creative motion is an emergent type of motion. It has no precursor in the inanimate world; it calls for its own mode of understanding—the kind we call psychological. If the laws of behavior could be subsumed under the laws of physics, psychology would be a lot easier—but, notoriously, they are not. Therefore, the motions of life-forms are not reducible to the motions of falling bodies, planets, etc.

What I have said so far is familiar enough (and familiarly disputed), but what I am about to say ought to strike you as bizarre, because I want to ask whether they are any analogues of the laws of motion in the case of the mind. Are there any highly general laws of nature that govern both material motions and mental “motions”? I am thinking primarily of Newton’s three laws of motion: does the mind follow laws that resemble these laws without being examples of them? If so, Newton’s laws could be seen as special cases of more general laws. The law of inertia is the easiest to generalize to the mind: just as a moving body will continue moving uniformly unless subjected to an outside force, so the mind will continue in its present condition unless affected by an outside influence. The mind doesn’t spontaneously change of its own accord but as a result of impinging causes. Nature stays the same unless caused to change; it doesn’t change of its own volition. A mountain will stay a mountain unless acted on from outside, and a mind will stay the same mind unless caused to deviate from its present state. Things don’t change for no reason—they are naturally inert. It is not, say, in the very nature of a belief to change over time without anything making it change. The mind changes only because it is forced to change not because it feels like changing. Left to its own devices, nature is lazy, stuck in its ways. But what about Newton’s second law—that force equals mass times acceleration? On the face of it no such analogue is possible, because the mind is not a moving object to begin with. The brain moves through space and may accelerate or decelerate; it may strike another object and exert a force on it (you could use brains as projectiles). It also contains motions of chemicals and electrical impulses. But minds don’t fly about the place, hitting other objects, causing damage; motion is alien to their nature (except derivatively on the body and brain). True, but they may have properties like motion as it features in the second law—they may have similar types of effect, exert forces of an analogous kind. Consider problem-solving. Think of this as a power of the mind: the ability to solve problems, practical and theoretical. It is analogous to a physical force. Are there, then, analogues of mass and acceleration? Mass is quantity of matter, so isn’t there such a thing as quantity of mind—largeness, capaciousness? The brain certainly admits of such description, and its dimensions correspond to degrees of intelligence and sophistication; don’t some animals have larger minds than others? The bigger the mind, the better it is at problem-solving; the greater the mental mass, the greater the mental force exerted on a problem (say, how to achieve a desired end). But that isn’t all: there is also the amount of mental activity and the speed of such activity. Some individuals and species are quicker of mind than others; they solve problems more quickly. We can then say that larger quicker minds exert more problem-solving force—as more massive faster projectiles exert more impact force.[1] If the mind were an immaterial substance, we could say that the quantity of mental stuff, along with its internal activity, contributes to (determines) its problem-solving capacity. Or again, the bigger and faster the brain, the more mental force it can exert. The mind doesn’t move through physical space, but it does something analogous—it cuts through intellectual space. In brief, mental force equals mental size (“mass”) times mental quickness (“velocity”). Generalizing, we have the following law: power equals quantity times activity. Intuitively, the more stuff there is of a certain kind and the more active (lively) it is, the more it can do. Big active things do more than small inactive things. Suns can do more than planets gravity-wise, and geniuses can do more than the average man problem-solving-wise. Impact is a function of size and activity-level. You can’t do much if you are small and inert, like a speck of dust; but you can do a lot if you are large and energetic, like a star or a human brain. Accordingly, there is a general principle (I won’t say law) that covers matter and mind—things that move and things that don’t move. Likewise, hot objects (including fires) can have more impact (do more harm) than cold objects, especially if they are large. Otherwise put, big energetic things have greater impact than small low-energy things—and that includes big energetic minds. This makes Newton’s second law an instance of a more general principle. It doesn’t make gravitational phenomena any more intelligible, but it does suggest a more general content to the law; indeed, it gives it something like an a priori status. As to Newton’s third law, I don’t see any clear analogue in the case of the mind—what kind of mental reaction would follow every action of mind? That law has no a priori component that I can discern and seems limited to the case of physical impact.

Does anything else in nature literally move apart from material bodies? And do we understand such motion? Space doesn’t move, unless we decide to reduce it to systems of bodies. Does time move? It doesn’t move through time, though we do speak of it in metaphors of movement—as if it has a forward momentum and a direction. Clocks move and are easily confused with time itself. Do fields of force move? Apparently not, though they may be propagated through space. Numbers don’t move (try pushing the number 2 aside). Does music move? We do speak of musical “movements” and music is connected to dance. Lawyers make motions, as do debaters. There are social movements. A person may move (“jump”) from one subject to another, or be “immovable” and “stuck in his ways”. A philosopher may make argumentative “moves”. Locutions of motion are common and natural. This doesn’t mean we understand motion very well, or at all; it merely means that we know it exists (like consciousness). The whole topic of movement strikes me as conceptually underexplored. Zeno went so far as to deny its existence, on conceptual grounds; he found motion paradoxical not merely poorly understood. The concept itself is far from clear, as witness the debate between absolutists and relativists. It is taken very much for granted. It seems to me quite puzzling and problematic: what is it exactly, where does it come from, what is its explanation, from whence does our knowledge of it derive (the senses or the intellect)? The concept of matter is by no means straightforward, and neither is the concept of space; but these enter into our concept of motion, along with force and time. We really have quite a superficial grasp of the nature of motion. We have a practical grasp of motion, as do other animals, which suffices for evolutionary purposes; but from a theoretical point of view, we are pretty much in the dark (Newton threw only a partial light on the subject).[2]

[1] You might wonder whether mental quickness and mental size are independent variables, as velocity and mass are. The brain is certainly a place of both size and quickness; indeed, a big brain is ipso facto slower just in virtue of the fact that it takes longer for a nerve impulse to traverse a large brain than a small one (say, an elephant brain versus an ant brain). Bird brains seem extremely quick but are not large. I think it is perfectly conceivable that a mind should have a large capacity but be relatively slow moving (I believe I have known people like that). Likewise, a mind could be quick but narrow in scope. Psychological quickness and size are not invariably correlated.

[2] There is an irony in this because motion is often trumpeted as one of science’s great triumphs—and so it is, up to a point. But not all mysteries and puzzles have been dispelled, as the thinkers of the renaissance recognized. Motion is still intellectually challenging, if not defeating. Positivism is just a way of sweeping the problems under the rug. Philosophers, in particular, should not regard it as a paradigm of transparency. It is closer to consciousness than we tend to suppose.

The New York Review of Books and Me

The New York Review of Books and Me

When Robert Silvers was the editor of the NYRB I wrote regularly for them. I must have written a dozen pieces for the magazine over a ten-year period. If anything, I felt over-employed by them. I got on well with Bob and looked forward to his many editorial phone calls; I also ran into him around town. We were friends. He treated me well. When he died, however, six or seven years ago, I stopped receiving requests to write from the new editors. I don’t know why; no one ever explained. I did write to ask whether my cancellation had anything to do with it and was assured that this was not so. I was told that it was simply a matter of their making too many commitments, with the implication that invitations would resume. They have not. What was once a good working relationship has devolved into a non-relationship. Meanwhile the magazine has seemed to me to have moved in a pronounced DEI direction, so much so that I cancelled my subscription to it and don’t even follow it anymore. What infuriates me is that the new editors evidently feel no obligation to continue the relationship the magazine once had with me without giving any explanation. I don’t believe their excuse about over-commitment: I strongly suspect that my cancellation was and is a factor, and that they have purposely pulled away from publishing academic philosophy as they did under Bob Silvers. No doubt they believe they are taking the high moral and intellectual ground in so doing, but nothing could be further from the truth. This is just one example of the cultural and moral degradation that has overtaken this country, stemming from the Left.

Skateboard Update

Skateboard Update

I have been skateboarding for 45 days, doing it nearly every day for about half an hour (following tennis practice). I now own three boards. I can say that I’ve got the hang of it. The cruising and steering part isn’t that difficult, but the push-off part takes some work. You have to learn to balance on your leading foot and not distribute your weight over both feet (I use my right foot to lead and my left to push). This is scary at first. You also need to lean slightly forward so as not to thrust the board forward underneath you, causing you to fall backwards. The skill comes gradually. The leading foot must be right in the center of the board or it will veer to the left or right, because the steering mechanism results from the tilt of the board as your feet press down. You push with your trailing foot close to the board in order to generate good power. Once you have this skill down the activity becomes quite enjoyable—I look forward to going every day. People smile and say hello to me (Latin people). I like the floating feeling. I like the feel of the board beneath my feet. I recommend it for older people. As I approach my 75th birthday, I’m glad I became a skateboarder.

I was playing tennis with Eddy the other day and I noticed something strange: I was moving faster around the court (I have never been slow). I was puzzled: why the increase in foot speed? Then I realized: it’s the skateboarding! Obviously, you need to develop leg strength (and balance) in order to skateboard, and this had carried over to my tennis movement. Thanks to the miracle of transfer of training, skateboarding had improved my tennis—not something I ever expected. The athletic world is a Unity (“sport monism”). In addition to this, I experienced a phenomenological shift in my arms: for the first time I felt that my left arm was acting as the main hitting arm on my two-handed backhand, not just playing a supporting role to my right arm. I have been working on this systematically over the last year and it happened quite abruptly: the left arm came into its own, accepted responsibility, took the reins. As I have described before, my knife throwing played a large role in this sinistral ascendancy, and now it had finally broken though. So, knife throwing (among other things) had helped my tennis stroke—another example of transfer of training. You have to smile. The CNS is an amazing thing. Who would have thought that skateboarding and knife throwing would be such a help to tennis playing? Has all this also helped with philosophy? I’m morally certain it has, though I have no direct evidence.
