Necessity and Change

Necessity and Change

Necessary facts don’t change. The table never changes from wood to plastic or metal: it is necessarily made of wood so can’t become made of plastic or metal. The number 3 is necessarily odd so can’t change into an even number. But the table can change its location or color and the number 3 can change its application (once it named the number of mice in a cage but later it stopped naming that number when the mice multiplied). Contingent facts can change: I can change from being a psychologist to being a philosopher, because I am not necessarily a psychologist (or was). So much, so indisputable. But is it right to say that necessary facts always remain the same in the same way some contingent facts remain the same? Some contingent facts don’t in fact change, but change is possible for them; but necessary facts can’t change—it isn’t in their nature to change. Necessary facts are necessarily changeless. But even this understates the case: they could not conceivablychange—change is completely alien to them. They necessarily necessarily don’t change; they are not even candidates for change. It is a kind of category mistake (a priori rejectable) to predicate change of them—like supposing that a number could dream or have sex. The question does not even arise. Necessities don’t change in the way propositions and geometrical figures don’t change: this is part of their very being. It isn’t an option. Necessities are permanent by virtue of their metaphysical status (as God is supposed to be). It isn’t a matter of luck or happenstance. So, to say that they never change, or necessarily never change, understates the depthof their permanence. They are not the kind of thing that could conceivably change. The table is not in the business of changing into plastic or metal; it has never even heard of such a thing. That would not to be it. Its entire identity is bound up with being made of wood.

I lay such emphasis on this point (which is not easily capturable in standard modal logic) because it seems to me that necessities don’t exist in time. Contingent facts exist in time, but necessary facts don’t. Time is alien to them, not their medium, not their ontological bag. They have never heard of time. They exist outside of time and want nothing to do with time. They don’t obtain for all time, except in the trivial sense that they are timeless. They are like numbers and other abstract objects—atemporal entities. Not omnitemporal (immortal, eternal) but anti-temporal, not even in that ballpark. It isn’t part of their “game”. Necessary facts (truths, objects) are conceptually opposed to time; they reject and repudiate time. It is not their medium of existence (similarly for space). We tend to underestimate their temporal indifference. Time has nothing to do with them, or them with it. Why should it—they don’t change. Where there is no possibility of change, there is no need for time. Modal logic and tense logic really have nothing to do with each other, despite their formal parallels. Predicating time or change of necessary facts is a category mistake, a conceptual foul-up. The two language games don’t overlap. There is a sharp disjunction between them. It is sheer sloppiness to say that necessities hold at all times and never change; this makes it sound as if they are just super-temporal and highly resistant to change. They are not supremely temporal and exceedingly tough—very stiff forms of contingency. They are not high-end industrial-strength contingency but creatures of a different species altogether. They don’t dochange and time; it’s not in their DNA. The fact that this table is made of wood is not a temporal fact at all, unlike the fact that it has a coffee cup on it. It is not a fact that obtains at time t and not at some other time. Nor is it a fact that obtains at all times. It obtains at no time. It hardly seems to obtain at all (too verb-like). Essence is timeless.[1]

A Story About John Searle

A Story About John Searle

In 1984 John Searle gave the Reith lectures in England. This was a big deal and quite an honor. I was asked by the BBC to join a small panel commenting on these lectures. After the program was recorded, we went to a boozy lunch set up by the Beeb. It was, shall we say, pretty lively. It culminated in John standing on his chair to make his point more emphatically. This is the kind of behavior I approve of (I was with George Soros once in St Barts at a restaurant in which we all stood on the chairs and table at the end of the night to dance, him included). How things have changed. I also had a brief correspondence with Sir Peter Strawson on the best use of the word “fuck” in literature (I cited a passage from Martin Amis). Those were the good old days. He also said to me once at an academic gathering in Oxford, “There are people here I wouldn’t mind talking to, but none I want to talk to”. He also said of Putnam, then visiting Oxford, “Hilary Putnam is a very sweet man, as he would be the first to agree”.

More on Searle

Jennifer Hudin sent me this.
Yes, actually, but I found a problem, I think, in John’s account of social ontology.  I’m not sure anything theoretical rides on it, but it is a puzzle nonetheless.  Everyone present agreed.
  I will polish the notes up for you.
  I was happy with the talk.  I managed to keep myself together (I learned  to do this during his trial), and tell some funny and touching stories about John no one knew.  There was a sweet part of John not many people saw.
  A woman from Vienna  flew in for the talk as a surprise.
  There was love for you at the talk, too.  This group, which is international, is the way the profession should be.  It was John’s favorite activity at the end of his life.
  We went over Ned Block’s tasteless comment that John valued winning a debate over the truth.  No one agreed. We had seen John have some pretty fierce debates with philosophers and then go out for beer afterwards.  Tom Nagel and he disagreed on a lot of major points.  But they were close friends.  Yes, I watched him debate Chalmers, but at the end of the day, John didn’t hold a grudge and he went on with his life.
  I’ll try to get that paper together and send you something.

Attention and Knowledge

Attention and Knowledge

In chapter XI (“Attention”) of The Principles of Psychology William James makes the point that the empiricists completely omit the contribution of attention in the generation knowledge. The reason is that attention possesses “a degree of reactive spontaneity” that breaks through the “circle of pure receptivity which constitutes ‘experience’” (402). Instead, he says, “My experience is what I agree to attend to” (his italics). Evidently, this is a good point: we only form knowledge in the normal course of events if we attend selectively to the object known about. We don’t acquire knowledge of things to which we pay no attention. Attending is a necessary condition of knowing. But attention doesn’t come from the world but from the knowing subject. It isn’t an “idea” deriving from an “impression”, still less a facet of the external object: it isn’t a stimulus. It is endogenous not exogenous. Presumably it is innate: the organism is innately primed to attend to some things and not others—the things that matter to its survival. Consciousness focalizes, concentrates, highlights. It doesn’t just passively reflect whatever impinges on the organism’s senses, indiscriminately. No attention, no knowledge, or very little. Attention is what provides cognitive uptake. A better version of empiricism would assert that all human knowledge derives from attention to the data of sense, and thus depends on innate features of the organism. It is therefore not a pure empiricism: the mind is not a blank slate but a self-generated spotlight focused on the objects of sense. Knowledge depends on the mind actively reaching out not just passively receiving imprints from outside. The theory might better be called “perceptual attentionalism”.[1]

The point carries over to the analysis of knowledge, as distinct from its origins. If to know is to perceive[2], then we must add that the perceiving must be attentive perceiving not merely peripheral or unconscious perceiving. That is, the primary knowledge we have is attentional perceptual knowledge; anything else is secondary. The paradigm of knowledge is attending selectively to a sensory object. Not true justified belief in a proposition, whatever that amounts to, but attention to a perceived stimulus—then we really know (“acquaintance”). This is the foundation of all genuine knowledge, the sine qua non. We are not seeing or hearing in an unfocused or distracted manner, but are focused and concentrated—drinking it all in, as we say. To that degree knowledge is a voluntary act: the act of knowing is the act of attending. You can try to know the object better by focusing on it longer or harder. Epistemology must not neglect this aspect of knowledge by focusing (!) on belief and justification. Seeing and attending are the basic epistemic operations. Knowing creatures can do these things even when belief and justification are beyond them. Strictly, then, we shouldn’t speak of the perceptual theory of knowledge but of the perceptual-attentive theory. Knowledge is the upshot of sensation and attention working together.

How does rationalism deal with attention? It is as silent as classical empiricism (James says nothing about rationalist epistemology). Tacitly, however, it helps itself to the faculty of attention: for attention is how innate information (for want of a better word) becomes conscious knowledge (as in Plato’s Meno). The learner attends to what is innate and thereby converts it to conscious knowledge. So, the rationalist theory of the origin of knowledge is really a combination of innate “ideas” and acts of inward attention. Attention is necessary in order that rational a priori knowledge should exist. Without attention the innate endowment would remain unconscious, merely latent. The acquisition of mathematical knowledge, for example, depends on the ability to attend selectively—to focus. It doesn’t arise from the innate material alone. Both a priori and a posteriori knowledge therefore require an active attentional faculty, not mere “experience” and “innate ideas”. The classical theories need to be enriched with this element. Attention is the medium (midwife) of knowledge; experience and innate information provide only the raw material. Without attention we would know nothing worth knowing. It may well be that our superior state of knowledge, compared to other animals, is the result of greater powers of concentration, i.e., selective attention. Attention is what actively and essentially mediates between the senses and knowledge proper. This is why the teacher exhorts his students to “Pay attention!”, because without attention knowledge cannot be formed. And we all know that what we don’t attend to doesn’t make it into memory. It is true that the passive imprint model is hard to discard, but we need a more active internalist conception of knowledge—its origins and nature. Knowledge doesn’t just happen to us; we make it happen.

But attention is quite puzzling. What is it exactly? We can study it experimentally, we can examine its neural correlates and behavioral expression, but we have little to say about it directly beyond metaphors (searchlight, spotlight). It is a touch mysterious, is it not? This is not surprising given its close connection with consciousness. Perhaps that is why theorists have been reluctant to invoke it in their theories. But nobody doubts its existence or importance, so it might profitably figure in our theories. This seems to be the situation: attention is integral to knowledge, but we don’t know much about it.[3]

[1] No one has ever explicitly espoused this theory to my knowledge.

[2] See my “Perceptual Knowledge”.

[3] Could we define attention as “the faculty of knowledge acquisition”? Is that its evolutionary function? It evolved to facilitate the retention of information. What came first is not belief or even knowledge but attention—the means by which knowledge is acquired. Organisms went from unfocused primitive awareness to focused cognitive pick-up. This is the right evolutionary epistemology. It may also characterize the development of knowledge in the child’s mind. The ability to attend is what defines what we call intelligence. We could establish a new school: attention-based epistemology. Educationally, we need to find ways to encourage and improve pupil attentiveness. It would therefore be nice to know more about it (“attention science”).

An Essay

Dear Prof. McGinn,

I hope you are well.

I saw that you recently posted an open call to dialogue on your blog, which reminded me that last year I wrote an essay in reply to one of your posts. You may find it interesting.

https://www.thephilosopher1923.org/post/on-cancelling-and-repair

Kind regards,

Mary

 

Dear Mary Peterson,

To be honest with you, I thought your essay was rubbish, though not badly written. Of course it’s bad for women to be sexually harassed and driven from the profession—when have I ever said otherwise? But it is also bad for men to be unjustly punished and driven from the profession. This is painfully obvious. Of course my work has value, which is why it has been valued (have you read any of it?). You seem to assume that I am guilty as charged, but that is the point in contention. I can’t talk about the facts of the case for legal reasons, but it would be easy for you to find these out for yourself by consulting publicly available legal documents. You obviously haven’t and gone by newspaper reports. The rest of what you say about me is also wrong, but I can’t be bothered to go into it. The idea that the cancellation has not materially affected my ability to publish and perform is factually false. Etc.

Yours sincerely,

Colin McGinn

 

PS. Your statement that my list of philosophy greats shows my bias is ridiculous. Just look at the curriculum in any philosophy department. Would you like to suggest a woman to go on the list?

One of the worst things about this essay is the complete lack of concern for any man who might be falsely accused and unjustly treated. It is as if this thought never entered the author’s head. She seems to find it inconceivable.

Block on Searle

Block on Searle

Ned Block says: “Searle was a pugilistic philosopher, much more interested in winning than in truth”. This is a nasty comment, coming so soon after Searle’s death. It isn’t so much the imputation of a desire to win as the suggestion that this was more Searle’s interest than the truth. The clear implication is that he would intentionally sacrifice the truth for the sake of a win. I think this is false and verges on the defamatory. He wanted to win because of what he took to be the truth—not in spite of it. Often, he was quite right in his judgment of the truth. No doubt some competitive ego was involved, but who isn’t guilty of that? It is the suggestion that he liked to win irrespective of truth, or that he preferred victory to truth, that is offensive. I myself had several intellectual run-ins with him, which were quite lively, but I never thought that he was trying to win no matter what the truth may be. And it is a calumny to claim that his writings were merely pugilistic; he wrote many books and articles in which he was transparently trying to find out the truth (and often did). He may have been pugilistic at times, but he wasn’t only pugilistic and unconcerned with truth. To say of a dead philosopher that he wasn’t concerned with the truth is a great insult, and in this case quite unjustified. He was certainly an effective critic of other philosophers’ views, but that is not to say he was merely pugilistic. This is all Block had to say about Searle as a philosopher and a man, and it is demonstrably untrue (as well as nasty). Is this the state that philosophy has reached?

Indictments

Indictments

I welcome the indictments the current administration intends to bring against a list of people; not because they are guilty of anything but because they are not. In each case the allegations will fall apart, thus exposing the meritless nature of the charges. This will not look good for the prosecutors. It will also result in the accused bringing up facts uncomfortable for the government; in effect, the government will be put on trial over and over again. What if not a single case issues in a conviction of guilt? What if judges throw them all out with a reprimand to the accusers? Has anyone thought about that? I would particularly enjoy an effort to indict James Clapper or Liz Cheney or Adam Schiff. They will make mincemeat of the accusers. I look forward to the spectacle.
