Sarah Bakewell quotes Montaigne, disabusing us of the false image of him "brooding" in his tower. He was a peripatetic, too: "My thoughts fall asleep if I make them sit down. My mind will not budge unless my legs move it." So, like Emerson he might have said "my books are in my library but my study is outdoors."


There's just something irresistibly alluring about the candid and disarming familiarity of his tone, that's drawn readers to this original essayist for four and a half centuries and obliterates the long interval between him and us. He makes uncertainty fun.

Also today, we'll consider the philosophical status of science. Montaigne the fallible skeptic actually had a better handle on it than Descartes, the self-appointed defender of scientific certainty. That's because science is a trial-and-error affair, making "essays" or attempts at evidence/-based understanding through observation, prediction, and test, but always retreating happily to the drawing board when conjectures meet refutation.
To answer some of my own DQs today:
Q: Are there any "authorities" (personal, textual, political, religious, institutional, traditional...) to whom you always and automatically defer? Can you justify this, intellectually or ethically? A: I don't think so. Whenever I feel a deferential impulse coming on I remind myself of the Emerson line about young men in libraries...
Q: Can you give an example of something you believe on the basis of probability, something else you believe because it has to be true (= follows necessarily from other premises you accept as true), and something you believe because you think it's the "best explanation")? Do you think most of your beliefs conform to one or another of these kinds of explanation? A: Hmmm... The sun will probably rise within the hour. I'm mortal. Life evolves. Yes.
Q: Do you think science makes genuine progress? Does it gradually give us a better, richer account of the natural world and our place in it? Is there a definite correlation between technology and scientific understanding? Do you think there is anything that cannot or should not be studied scientifically? Why? A: Yes, yes, yes, no. Science is a flawed instrument, because the humans who practice it are finite and fallible; but we have nothing to take its place. We shouldn't be scientistic, to the neglect of all the other tools in our kit (including poetry, literature, history, humor), but we definitely should be as scientific as we can.

Descartes
Rene Descartes, not at all (Pythons notwithstanding) a "drunken fart," simply wanted to know what he could know for certain. He asked his version of
the Howard Baker question. (The majority of students in my Tennessee classrooms could not identify the statesman-Senator when asked, the other day. Sigh.)
His skepticism was methodological, his goal was indubitable certainty. This, he thought, would serve the new science well. He misunderstood the self-correcting, probabilistic, fallibilistic nature of empirical reasoning. But most philosophers still think it’s worth wondering: how do you know you’re not dreaming, not being deceived by a demon or by your senses, not mistaking your own essential nature?
Still, cogito ergo sum overrates intellect. You don’t have to think, to demonstrate your existence. You just have to do something… even, as an old grad school pal used to say, if it’s wrong. (NOTE TO CLASS: I flip-flopped Descartes and his predecessor Montaigne, the anti-Descartes, on our syllabus: Descartes before
the horse M. fell off of.)
Descartes' different aspects - mathematician, scientist, Catholic etc. - might suggest his split allegiance between Teams Aristotle and Plato. Both would probably like to claim him. I think he belongs with the armchair Platonists.
Reducing the operations of the universe to a series of lines,circles, numbers, and equations suited his reclusive personality. His most famous saying, “I think, therefore Iam” (cogito, ergo sum), could be stated less succinctly but more accurately as 'Because we are the only beings who do math, we rule.'
For Descartes, the essence of mind is to think, and the essence of matter is to exist-and the two never meet... we are the ghosts in the machine: souls in a world machine that operates inexorably and impersonally according to the laws of geometry and mechanics, while we operate the levers and spin the dials."
The Cave and the LightI usually think of
Charles Sanders Peirce as Descartes’ most practical critic, and I agree with him that a contrived and methodological doubt is not the best starting place in philosophy.
But it occurs to me that an even more practical alternative to what I consider the misguided Cartesian quest for certainty is old Ben Franklin’s
Poore Richard. His is not armchair wisdom, it comes straight from the accumulated experience of the folk. Some of that “common sense” is too common, but plenty is dead-on. “Early to bed, early to rise…” has definitely worked for me.
Still, says
A.C. Grayling, "we may disagree with Descartes that the right place to start is with the private data of consciousness" rather than the shared world of language and common experience; but even if he was wrong he was "powerfully, interestingly, and importantly wrong." Russell concurs.
The thing is, the quest for certainty in philosophy tends to go hand-in-glove with the assertion of rational necessity. That, in turn, courts determinism and fatalism. Do we really want to rubber-stamp everything that happens as fated, not free? Hobbes (the contractarian and the cat) did. Calvin learned not to.

Is there anything we know or believe that we could not possibly be mistaken about, or cannot reasonably doubt? Certainly not, speaking at least for myself. But I'm next to certain that I'm more-or-less awake, at this hour, as the coffee drains.

I'm also pretty darn sure that I am (and do not "have") a body/brain. When I think of who, what, and where I am, though, the answer is interestingly complicated by all my relations (I don't just mean my familial relations): I am inclusive of a past and a future (though it keeps shrinking), and of wherever my influence (for better or worse) manages to stretch. I am vitally related by experience (actual, virtual, vicarious, possible, personal, interpersonal) to points far and wide. And, to actual physical objects in the extended world - not merely to possibilities of familiar object-like patterns of perception, as the
phenomenalist has it. I'm not trapped in my skin, and we are definitely not alone in a
solipsistic universe. Like
Dr. Johnson, contra Berkeley, I find the pain in my toes (or hips) decidedly more substantial than an immaterial idea.
Or ghost.

I don't believe in ghosts, except metaphorically. (I am haunted by opportunities missed, possibilities unnnoticed, diems uncarped.) But most of my metaphorical spooks are Casperishly friendly (albeit
incoherent, dualistically speaking). This is true of most people who read and think a lot, isn't it? We're in constant, happy communion with the dead, the remote, and the prospective members of our
continuous human community. Books transport us to their realms, and to the great undiscovered country of our future.
