Santayana and The Inflexibility of Age

Last week I discussed the passage in Santayana's writing whence we get the cliche about those of "cannot remember the past" or (as it is often misquoted) "cannot learn from history."

In the context of that discussion, I also quoted the philosopher saying this (about the human life cycle): "Last comes a stage when retentiveness is exhausted and all that happens is at once forgotten; a vain, because impractical, repetition of the past takes the place of plasticity and fertile readaptation."

A friend emailed me a question: must it be thus?  Did Santayana think he was describing an inevitable result of age here, or a statistical likelihood, or something else?

Good question.  I don't think Santayana's text gives us a definitive answer to that. But we might remember his own stress on individuality in this whole passage.  "Human nature," he wrote, "in the sense in which it is the transcendental foundation of all science and morals, is a functional unity in each man; it is no general or abstract essence, the average of all men's characters, nor even the complex of the qualities common to all men. It is the entelechy of the living individual, be he typical or singular."

In that context, I think we can take the somewhat later reference to the exhaustion of retentiveness and its terrible consequences as a statement of what is "typical," not an exclusion of the possibility of "singular" individuals who will escape that fate.

Indeed: Santayana was such a singular individual, one who maintained his flexibility to the end. I've been quoting from The Life of Reason, an ambitious multi-volume work he wrote while he was teaching at Harvard, in the early years of the 20th century. Years later, when another man might have settled into the role of defending and elaborating the system expounded there, Santayana essentially started from scratch, in an equally ambitious project, The Realms of Being.  The four volumes of this work came out between 1927 and 1940. Thereafter, Santayana undertook the considerable editorial task of creating a one-volume version of The Realms of Being, which was published in 1942, when he was in his late 70s.

So if he believed he was saying something invariant when he wrote that "repetition of the past takes the place of plasticity, [for the elderly]" he later learned better.

Not all redundancy theory is alike

Deflationism as to truth is a major trend in epistemology, at least in English speaking countries, one that has lasted throughout much of the 20th century into the 21st. But let us back up a bit: century ago, a triangular debate was underway as to the Meaning of Truth. The correspondence theory, affiliated with various forms of realism about the external world, represented one corner of this triangle. The coherence theory, affiliated generally with idealism, represented another, and pragmatism the third. But the deflationists sought to ring the bell and end the fight, declaring that "truth" doesn't mean anything interesting, i.e. that the grand metaphysical puzzle of its significance is actually a hot air balloon.

Personally, my view is that deflationism is well and good, but if the air is let out of this balloon it will go somewhere else. The matters that Russell, Royce, and James debated back in the old days under the label "truth" will still have to be thrashed out under other labels.

Today, I wish simply to observe that not all deflationism is alike. One variant of deflation is the "redundancy theory of truth." According to this view, to say "it is true that the grass is green" is the same thing as to say "the grass is green," so the extra words are redundant. One of those extra redundant words, of course, is the word "true," no matter how attached to that one we tend to be. Other forms of deflationism give the concept of "truth" some minimalist function. It is not just redundancy. It is, for example, a type of performance. Or a way of creating emphasis (like using italics in the way I just did.) Still, the hot-air of metaphysics is to be deflated.

Now comes a further revelation. File this under the heading "philosophy is fractal." For it appears that not all redundancy theories of truth are alike, either. According to Pierre le Morvan here, there are at least three distinct redundancy theories: a "robust" redundancy that Morvan associates with W.E. Johnson; a skinnier redundancy that Morvan calls the "received interpretation," and an intermediate view he associates with Frank Ramsey.

His explanation of the differences among these, though, makes my brain hurt, so further into the exploration of this Mandelbrot set I will not press.

The Invention of Lying

I finally saw the recent Rick Gervais movie, "The Invention of Lying," on Friday evening.

Here's a link to the wikipedia article, though let this be a 'spoiler' warning before you click it.

Anyway, the movie is very funny. It is also gutsy, because it is an implicit philosophical argument of a sort that would be extremely unpopular in the U.S. were it a tad more explicit. The movie protrays a society much like the contemporary northeastern US within an alternative universe in which humans have never lied, never created any fiction for that matter, and don't even have words to explain the possibility of doing so. Their movies are filmed lectures about dramatic events from the past, and indeed we catch a quick reference to an upcoming film that will be called "The Invention of the Fork."

The protagonist of "The Invention of Lying" evidently has some neurological quirk that makes him different from everybody else, in that he can "say something that isn't," as he puts it at one point, trying to explain it to a friend.

That protagonist, Mark Bellison, played by Gervais, is surprised to discover this difference about himself, and for the most part he uses it benignly. He does con a bank out of some money -- but that is presented as due to desperate circumstances. Later he helps a homeless man, and offers his mother consolation on her deathbed.

Here we get to the crux of the matter. There is no evidence in this film that any sort of religion existed prior to the "invention of lying." His dying mother is expressing the predominant view of this alternate world's human species when she tells him how frightened she is at the imminent prospect of entering "a giant everything of nothingness." Gervais makes her final moments comfortable by telling her that she is going to a wonderful place where all the people she has loved and lost over her lifetime are waiting for her -- a place without pain or want.

It is important to the philosophical weight of this movie that the reason that he starts telling stories about the nice place we all go to after death is a benevolent one, told by a guy with whom we can't help but sympathize. Yet it is still a lie. And one with unexpected consequences.

Unbeknownst to Mark Bellison, the doctor and a handful of hospital staffers are behind him, listening to this conversation. They hear all these things about the life after this one, and since there is no concept of "saying what isn't" in their world, they believe it. They want to tell people this wonderful news. Word spreads, and soon the protagonist is a prophet. Everybody wants to know more.

One incidental oddity that struck me is that their world has a history to it very much like our own. From various references one gathers that there was a "black plague" that took place in the 14th century, and that the use of terms such as "14th century" or "1st century" for that matter, mean pretty much to them what they mean to us. But why, in a world without religion, would the "1st century" be called that? Why would a count have begun then?

Another less-incidental oddity (it may be considered part of the film's message) is that the ability to lie is connected to an ability to consider the subjective aspect of other people. Mark and his love interest (Anna, played by Jennifer Garner) have an idyllic moment in a public park, which turns into his effort to explain to her that people are not solely what they seem -- that, for example, the overweight fellow lying on the grass to their left may not be the lazy loser he seems, but may be "the world's greatest poet," who gets his inspiration in this way.

Over time, Anna grasps the seeing-beyond-the-surface part of Marks' message, although she never does really grasp the 'lying' thing. So: are those two memes closely connected, or not?

There's something else that sticks with me. At some point soon after his first lie, Mark decides to help a homeless man -- a guy who has been sitting on the street with a sign that says, "I don't understand why I'm in the street and you have homes." This fellow is played by Michael Patrick Gough according to imdb. Mark takes him into the bank, says something to the clerk (we can't overhear this bit) and the clerk hands the homeless guy a large chunk of money.

Leter, we see a homeless man again. The shot comes and goes so quickly that I'm not sure whether it was the same guy, and/or the same sign (though another wordy sign was involved). What is the message there? That lying doesn't realy solve social problems? Or does this imply also that money doesn't really solve social probelms, and that even if the money had been given honestly the original homeless guy may have difficulties, such as an expensive addiction, that would have put him back on the street anyway?

Good Will

Let's think our way through Kantian ethics for a change of pace this Sunday.

There is nothing that can be called "good" without qualification except a good will. Everything else is sometimes good, sometimes not, depending on context. But a will aimed at doing its duty is always good.

That, at least, is the heart of what Kant was trying to tell us.

If you accept that much as valid (a big "if") the next logical question you'll raise may be: how does one determine one's duty?

This is where the categorical imperative comes in. There are two inter-related formulations. First, one should always act such that one's action could become a universal law.

This means, for example, that one should never lie. Lying couldn't become a universal law because if all statements were lies, language would lose all value and significance, and the act of lying itself would become impossible. So lying is always and everywhere a violation of duty.

From this "universal law" formulation, Kant inferred another version of the categorial imperative, the means/end formulation. Never treat another human being as entirely a means to an end, but always as an end in himself.

All of this has given rise to an enormous literature of exposition and debate, of course, but I hope I've given you a sense of the inter-relation of some of the basic terms.

One standard objection to this view of right and wrong is sometimes summarized in the phrase "one thought too many." If my wife is drowning in a lake, and I swim out and save her, Kant would think this act moral only if I saved her because it is my duty. What if I just save her because I love her? Or because I'd feel devastated if she weren't around any more? As I understand it, even those are the "wrong" reason for Kant, and remove value from the action.

Only duty is the right reason.

That sounds absurd because if I'm actually standing ont he shore reasoning about my duty, I'm over thinking the matter. One thought (at least) too many. And even if I do save her life, our marriage may well be in trouble.

Good article on this point? Barbara Herman, "On the Value of Acting from the Motive of Duty," THE PHILOSOPHICAL REVIEW (July 1981).

Determinisms: Hard and Soft?

William James once drew a distinction between hard and soft determinism, in an essay often cited these days in discussions of what is nowadays called compatibilism. But I'll get to that.

Let's first understand James on his own terms. Early in an essay on the human will, on whether and to what extent its expressions are all fated, determined since forever ... early on he addresses the question of terminology. The word "freedom" is such a nice word, used so ringingly in anthems and in the course of orations on patriotic holidays, that everybody on every side of an argument will want to be standing up for "freedom rightly understood."

Old-fashioned determinism is the sort that disdains such nice words. Hard determinists don't shrink "from such words as fatality, bondage of the will, neccessitation, and the like. Nowadays, we have a soft determinism, which abhors harsh words...." The word both sorts of determinists abhor is "chance," which stands for the simple notion that the parts of the universe "have a certain amount of loose play on one another, so that the laying down of one of them does not necessarily determine what the others shall be."

James is writing in order to defend indeterminism, not to take sides between the two sorts of determinists, so he accepts the word "chance" as a statement of what he believes in, and abandons the word "freedom" to the grubbers after nice words.

The issue of things (as distinct from the issue of words) is between determinists and indeterminists, between believers in chance and believers in fate.

Now, the debate as James understood it has gone the way of all flesh. On the one hand, quantum mechanics, Godel's theorem, chaos theory and such developments have acclimated everybody to the reality of chance in the world. On the other hand, the fact that everybody now believes in chance makes chance seem less important.

Debate does continue over compatibilism. This is the view that moral responsibility and human autonomy in some valuable sense is consistent with a mechanical/materialistic theory of the universe and of our place in it.

The contrary of compatibilism of course is incompatibilism, which comes in two varieties. Incompatibilists can either say, "No, such a view is incompatible with moral responsibility, which is a good reasons for looking for flaws in such a view, because we ought to work to keep the idea of moral responsibility." We can call this the II position (incompatible, thus immaterialism)!

Another set of incompatibilists can say, "No, such a view is incompatible with moral responsibility. So much the worse for our notions of moral responsibility though -- we're going to have to learn to live without them." Call that the IA position (incompatible, thus amorality)!

James' words on the different sorts of determinists with whom he was contending have been shanghied into this debate, so that "soft determinism" is sometimes used to describe compatibilism (we can have materialism and morality too). "Hard determinist" is used to describe the IA position. This implicitly equates James' sort of indeterminism with the II position.

I don't think that's fair to him, though. Were he alive today, and up to date on contemporary science and philosophic debates, my own suspicion is that he'd still believe in immaterial aspects of the cosmos, as he did, but he wouldn't link that notion tightly to the foundations of morality. Just as he didn't want to chase after exclusive title to the word "freedom" and was happy to grant it to the determinists if they wanted it.

He would likely be a compatibilist, but he probably wouldn't regard compatibilism as all that important a point to make, because the reasons/motives that would impel him to keep looking for the immaterial would be quite different from those to which the II position appeals.

W.D. Ross

Today I'm going to describe the ethical theory of Scottish philosopher W.D. Ross, author of THE RIGHT AND THE GOOD (1930).

Why? Well ... because Ross' view, which he called intuitionism, was for a time influential, although it has siince fallen into obscurity, and such Ozymandias-type theories are intrinsically interesting.

Also, because Ross' views seem a British-isles re-write of Jamesianism, of the sort of pluralism expounded in The Moral Philosopher and the Moral Life.

Ross argued that there are several obligations that play a role in moral reasoning -- in deciding what we ought to do. Each of these obligations is in itself ony a "prima facie duty," because any of them can be counter-balanced by others. The "absolute duty" is by definition that which, in a given situation, outweighs any others.

How do we know which duty in cases of conflict is the absolute one? Our intuition (hence the name for the theory) will tell us case-by-case, which feels weightier.

Technically, Ross' views are classed as "deontology," that is an example of views in which the right dominates the good, duty exists separate and sometimes above the issue of making-the-world-better. Well, Ross' list of duties included at least two that a making-the-world-better philosopher would approve of. We have a duty of self-improvement and we have a duty of beneficience -- of improving the lives of others. Still, there are lots of other duties on his list that can run against these, such as fidelity and gratitude, so if he's right, then there will be times when my duty will be to act in such a manner as to decrease the amount of good.

Analytical Philosophy

And they say the analytic tradition in philosophy is moribund!

In a recent book on the contending definitions of truth in philosophy today, a book with a distinctly Russellian/Wittgensteinian focus, I've found a passage that bears on that accusation. To me, its a very funny piece of writing too, though I'm sure it wasn't intended as such.

The author, Matthew McGrath, early on mentions sentences that contain the word "sake," as in "Lois Lane risked her life for Clark Kent's sake."

He then discusses the problems that we might run into if we regarded a "sake" as a thing, something Clark possesses. (Like a pet?) -- so that we might try to understand the sentence as analogous to, "Lois Lane risked her life for Clark Kent's collie." He calls this "sake realism."

"The opacity of sake-talk makes sake realism objectionable. But it is objectionable for reasons of a more general relevance. By accepting sakes, we would confront a panoply of seemingly unaswerable questions: Do all things have sakes? My socks? the number 7? Do sakes themselves have sakes? Why is it that the things that have sakes have only one sake?"

You might think that I'm being unfair, taking this out of context. Surely he was attempting a reductio? Some opponent's view strikes him as analogous to "sake realism" and, accordingly, absurd?

Not quite. He's playing defense in this passage. As near I can tell, he's trying to say that although his view of truth bears some relation to "sake realism," it is sufficiently distinquishable to survive such a reductio.

But never mind about that. The next time you want to give your mind the cleansing benefits of an Zen koan, just recall the question: "Do sakes themselves have sakes?"

But don't do it for my sake.

Mr. McGrath needs to get out more.

Knowledge is warranted belief -- it is the body of belief that we build up because, while living in this world, we've developed good reasons for believing it. What we know, then, is what works -- and it is, necessarily, what has worked for us, each of us individually, as a first approximation.
