Episode 48: Merleau-Ponty on Perception and Knowledge

Discussing Maurice Merleau-Ponty’s “Primacy of Perception” (1946) and The World of Perception (1948).

What is the relation of perception to knowledge? In M-P’s phenomenology, perception is primary: even our knowledge of mathematical truths is in some way conditioned by and dependent on the fact that we are creatures with bodies and senses that work the way they do. Science is great, but it doesn’t discover the truth of things hiding behind perception: it is an abstraction from certain kinds of perceptions. Other modes of approaching things, e.g. art, can equally well give us knowledge, though of a different kind.

Mark, Seth, Wes, and Dylan argue over whether this thesis is just a bunch of truisms and despair over not having read The Phenomenology of Perception, the longer work which what we did read was meant to summarize. Is M-P just saying that scientific knowledge is defeasible, which scientists already believe? Read more about this topic.

Topic for #48: Merleau-Ponty on the Role of Perception in Knowledge

Maurice Merleau-Ponty’s magnum opus–his equivalent to Being & Nothinginess or Being & Time–is The Phenomenology of Perception. It is reputed (by Seth, at least) to complete Heidegger’s project by paying proper attention to our embodiedness: we have bodies, with specific perceptual limitations and are not only culturally but physically situated in ways that (as Heidegger insisted) make Cartesian doubt a sham. Scientism is a mistake, and in particular attempts to explain consciousness without allowing first person reports (i.e. by strictly applying the scientific method) will be hopeless, because all inquiry starts with, is founded on, and presupposes this situation of us already in the world, with other people, with all these layers of meaning packing up our conscious experiences and even our unthinking behavior, to be elaborated by phenomenology.

So the Phenomenology of Perception is a very fat book that purports to give an existential phenomenology, from an analysis of perception (attention, judgment, “the phenomenal field”), to the various aspects of having a body (its spatiality, sexuality, expression, and how mechanistic psychology and classical psychology teat it), to a consequent analysis of time and freedom. …All stated with much less of the horrific made-up terminology of Heidegger or B&T-era Satre than you’d expect.

However, that book is much too long, and takes a long time to get around to saying much, so instead, we chose to read a sort of presentation of that work to a lay audience.World of Perception,from 1948, is actually a series of radio lectures for a general audience, presenting on broad strokes what the viewpoint of the kind of philosophy he represents has to add the popular view of science.

Can we be philosophical realists?

Reality is like a thief in the night (from Owl of Minerva.org)

The analytic philosophy of logical positivism or logical empiricism, which dominated 20th-century Anglo-American scientific thinking, leaves philosophy with a complex and problematic legacy that must be addressed and overcome if we are to have any hope of a renewed, meaningful, philosophically rational realism.

On the one hand, the positivist view of philosophy is deflationary, diminishing and even de-legitimizing the very notion of philosophy.  The idea that philosophy was to become ‘underlaborer to science’, following Lockean empiricism, proved quite popular with scientists and science enthusiasts, and to this day informs the common belief that philosophy can be wholly displaced by empirical investigation on pretty much any question. On the other hand, following the linguistic turn and Thomas Kuhn’s historicist account of science, many disillusioned analytical philosophers have become convinced that their discipline cannot really provide any affirmative, unchanging, principal foundations to scientific thinking. For example, the principles of method and observational verification sounded great until one realized that the principles themselves couldn’t be reached by method nor verified by an empirical observation.

What is a Philosophical Explanation?

On some comments to a recent post by Mark on Sam Harris and the ought/is distinction, I noted that Harris assumes that “happiness” (or “flourishing”) is an un-problematic concept — a well-established ruler against which one can easily measure the success or failure of behaviors. Hence when he claims that science can tell us what is right and wrong — by telling us what makes us happy — he has merely tabled the harder, philosophical problem of what happiness is (not to mention whether it ought to be our measure of right and wrong).

In yesterday’s Philosopher’s Stone, Gary Gutting mines a similar vein: the nature of happiness is a) not uncontroversial and b) a philosophical rather than scientific question. Empirical studies that try to establish the nature of happiness by simply asking people what makes them happy are problematic because the meaning of “happy” is unclear and may vary between respondents significantly:

But the most powerful challenge concerns the meaning and value of happiness.  Researchers emphasize that when we ask people if they are happy the answers tell us nothing if we don’t know what our respondents mean by “happy.”  One person might mean, “I’m not currently feeling any serious pain”; another, “My life is pretty horrible but I’m reconciled to it”; another, “I’m feeling a lot better than I did yesterday.”  Happiness research requires a clear understanding of the possible meanings of the term. For example, most researchers distinguish between happiness as a psychological state (for example, feeling overall more pleasure than pain) and happiness as a positive evaluation of your life, even if it has involved more pain than pleasure.

David Eagleman on the Neuroscience and the Unconscious

Terry Gross has an interesting interview with neuroscientist David Eagleman, author of Incognito: The Secret Lives of the Brain (Incidentally, if you’re in Boston you can catch him at Harvard Bookstore on Friday). Eagleman’s book is about, among many other things, the neuroscience of unconscious processes and their importance to our behavior (something of the particular interest to me); and has some very neo-Kantian ideas about space and time being “constructed” by the brain and not “out there.”

Defending Religion from the Left (Jackson Lears on Sam Harris)

Historian Jackson Lears has an interesting attack on Sam Harris in The Nation. I’m not endorsing everything in this everything-but-the-kitchen sink assault (on both Harris’ religious and moral theories), but it’s interesting and worth a read.

When Keeping it Real Goes Wrong

Far SideA research physicist friend of mine who works at Lawrence Berkeley National Laboratory is a bit of a global warming skeptic. When I brought up all the scientific research on the subject, he said, somewhat dismissively, “Yes, but anyone who gets a PhD in climate science goes into it with an agenda. No one goes into particle physics just to prove a point. So no, I don’t always trust their research.” Not being a scientist myself, I had no clever rejoinder at the time, other than to say, essentially, “Well, 50,000 climate scientists can’t all be wrong!” But what if most scientists tend to be wrong most of the time? And not due to political agendas, but academic, professional, or even psychological ones?

A good New Yorker article appeared last month regarding the fallibility of scientific research as currently practiced, or perhaps as inevitably practiced. There is a lot to chew on here, once you consider the ramifications.

Simon Blackburn vs Sam Harris: Can Science Tell us Right from Wrong?

In a debate with Patricia Churchland, Peter Singer, Sam Harris, and Lawrence Krauss, Simon Blackburn explains why Harris simply has it wrong on whether science can provide substantive guidance on morality:

Youtube

There is no doubt, he notes, that “science can inform our values” (and I would add that this goes trivially for many other types of knowledge). But “as to whether you need nothing but science”, “I don’t agree with Sam about that and neither do the other three speakers we’ve heard so far.”

Nelson Goodman on Induction (Grue and Bleen!)

grueOn our Goodman episode, I start out by trying to give a short explanation of Goodman’s “New Riddle of Induction.” When we’re presented with evidence for a general claim, how do we tell which general claim the evidence is in support of? Goodman contrasts the predicate “green,” which we might think we can project to future cases when we see that all current emeralds are green, with “grue,” which is defined as green previous to this moment and blue after this moment. He argues that our past observations don’t tell us which predicate should be projected into the future; we have to give an explanation why we intuitively want to project green and not grue, even though we haven’t yet had an experience running counter to the hypothesis that all emeralds are grue. Giving an account of this is more difficult than you might think, and this essay shows Goodman in full-bore analytic mode: very methodical, but still readable and actually fun if you’re into that sort of thing, as opposed to his mathematical philosophy, which I think is no fun under any circumstances.

Episode 28: Nelson Goodman on Art as Epistemology

Discussing Goodman’s Ways of Worldmaking (1978).

What’s the relationship between art and science? Does understanding works of art constitute “knowledge,” and if so, how does this relate to other kinds of knowledge? Goodman describes art as a symbol system (including art like instrumental music that doesn’t seem representative), which can symbolize successfully or not. While there is no one set of concepts by which to judge all art (different types of art and other descriptive endeavors establish incommensurable “worlds”), neither is art an anything goes endeavor where the individual spectator is the only determinant of quality.

We’re joined by painter Jay Bailey to bring up lots of amusing artwork examples (The Monkees! Thomas Kinkade! Self-mutilation as art!) and tell us how well Goodman’s account accords with his understanding of artistic practice (his answer: not so well).

Who’s Qualified to Speak about Religion?

South Park Dawkins

The most recent comment to yesterday’s post on atheism was a quote (thanks, Jonathan!) from Jose Ortega y Gasset used on this blog to argue that scientists shouldn’t be weighing in on matters of religion and ethics which are, after all, not their specialty.

The point is well taken, reflecting Socrates’s general criticism that every expert in one area thinks he’s an expert in everything. However, Ortega y Gasset’s critique is equally applicable to anyone who has not engaged in the requisite level of philosophical reflection, including any religious believers who have not studied epistemology and clergy who have not thought a lot about meta-ethics.

How much is “a lot” or “requisite?” I don’t know. Dawkins’s book is, unsurprisingly, at its strongest when talking about natural selection; his comments about ethics and other matters are certainly researched (much like Freud’s comments on anthropology and other subjects that make up his speculative work), but Dawkins is obviously not deeply familiar with the vast canon of philosophy in these areas.

Stephen Hawking: “Nothing” has more explanatory value than “God”

Stephen Hawking makes perhaps one of the dumbest forays by a scientist into philosophy that I have ever seen:

That is not the answer of modern science. As recent advances in cosmology suggest, the laws of gravity and quantum theory allow universes to appear spontaneously from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going.

Well that settles it. Something spontaneously arose out of nothing. No need for an explanation of that. Move on people, nothing mysterious here, stop asking questions. The blue touch paper lit itself, and there is something called “nothingness” which contains that blue torch paper as well as laws governing it. Perhaps this is all, in some Deepak Chopra sense, true. But it is not “the answer of modern science.” It is purely speculative, and whether we want to use the word “God” to describe the mystery of spontaneous generation or leave it at a nothing containing the seed of spontaneous generation seems to be a semantic distinction, with the latter in no way naturalizing or demystifying the former.

Episode 22: More James’s Pragmatism: Is Faith Justified? What is Truth?

Discussing William James’s “The Will to Believe” and continuing our discussion from Episode 20 on James’s conception of truth as described in his books Pragmatism and The Meaning of Truth, again featuring guest podcaster Dylan Casey.

Does pragmatism give ground for religious belief, like if I say it feels good for me to believe in God, is that in any sense a legitimate grounds for that belief? Is belief in science or rationality itself a form of faith? Is religious belief a “forced choice,” or does it just not matter what you believe?

Also, we sort further through James on truth: truth is created by us, but what does that mean? That only statements actually verified or otherwise useful are true, or can have a truth value (true of false) at all? In saying that we create truth, does that make James a relativist, and if so, is that bad?

Read “The Will to Believe,” Pragmatism, and The Meaning of Truth (the most useful chapters for our purposes are 3, 5, 8, 9, 12, and 15).

Episode 20: Pragmatism – Peirce and James

Reading Pragmatism by William James and “The Fixation of Belief” and “How to Make Our Ideas Clear” by Charles Sanders Peirce.

Is truth a primitive relation between our representations and things objectively in the world, or is it an analyzable process by which propositions “prove their worth” by being useful in some way, like by fitting well with other portions of our experience or being delicious?

Peirce, the inventor of pragmatism, focuses on the philosophy of science and thinks of inquiry as a way for us to just settle on any belief we can stomach. James, who popularized pragmatism, has a wider view that applies not only to science but to religious beliefs. If it makes you feel nice to believe in Hogwarts, should you do so?

The episode features guest podcaster Dylan Casey (previously from our quantum physics episode).

Episode 19: Kant: What Can We Know?

Reading Immanuel Kant’s Prolegomena to Any Future Metaphysics, which is sort of a post-publication Cliff’s Notes to his Critique of Pure Reason.

Do we have any business doing metaphysics, which is by definition about things that we could not possibly experience?

Kant says that yes, we can, to a limited extent, but that everyone before him did it wrong, because they didn’t understand how our minds interact with the world to create experience. He insists that once you read his book, you’ll never be satisfied with such “twaddle” again!

LEARN about the faculties of Sensibility, Understanding, and Reason! THINK about whether geometric truths are justified by our intuition of space (maybe) and arithmetic is grounded in our intuition of time (probably not). DOUBT whether we actually impose causality on our experience as Kant says! MARVEL at our guest participant, Azzurra Crispino, as she augments the number of speakers on this episode to a PERFECTLY SQUARE number! GAWK as your world is turned up-flicking-side down by Kant’s “Copernican Revolution” (a term we neither use nor explain in this episode)!

Are the majority of published scientific research claims false?

The epistemology vs. epidemiology (Odds Are, It’s Wrong – Science News):

“There is increasing concern,” declared epidemiologist John Ioannidis in a highly cited 2005 paper in PLoS Medicine, “that in modern research, false findings may be the majority or even the vast majority of published research claims.”

Nowhere are the problems with statistics more blatant than in studies of genetic influences on disease.

Statisticians perpetually caution against mistaking statistical significance for practical importance, but scientific papers commit that error often. Ziliak studied journals from various fields — psychology, medicine and economics among others — and reported frequent disregard for the distinction.

Such sad statistical situations suggest that the marriage of science and math may be desperately in need of counseling.

“What does probability mean in real life?” the statistician David Salsburg asked in his 2001 book The Lady Tasting Tea. “This problem is still unsolved, and … if it remains un solved, the whole of the statistical approach to science may come crashing down from the weight of its own inconsistencies.”

Fodor, Darwin, and the Philosophy of Science

I had been looking forward to Jerry Fodor’s What Darwin Got Wrong (co-authored with Massimo Piattelli-Palmarini), not because I have anything against Darwin but because Fodor is a superb writer, the well-respected cognitive scientist who “laid the groundwork for the modularity of mind and language of thought hypotheses,” and a worthy opponent of the idiocy of evolutionary psychologists who seem to think that every phenotypic trait must have been subject to selective pressure (no).

The book is extremely disappointing, and I don’t have the heart a the longer post analyzing it. It’s enough to read Ned Block (fantastic philosopher of mind guy) and Philip Kitcher‘s review–that is, complete dismantling of a thesis that just seems bizarrely wrong.  F&PP’s response and B&K’s reply are also very interesting. I will say that B&K’s accusation that the book shows “no detailed engagement with the practice of evolutionary biology” is an ad hominem overreach. The book gives a competent (and extremely informative) overview of the field, even if it is mistaken about its implications. Earlier in the review, F&K merely call it “biologically irrelevant”–an accurate claim if the relevance is to F&PP’s philosophical argument. But this merely highlights the fact that the book’s problems are philosophical, not biological.

(I’m going to apologize in advance for the intemperance of the rest of this screed).

These claims are particularly unfortunate in that they have encouraged an outpouring of zealous and  anti-intellectual scientism by reviewers (not to mention comment section trolls) who make no claims even to have read the book and assume its flaws must be scientific rather than philosophical. The they-just-don’t-understand-science claim has become a rationale for berating philosophers for their pie-in-the-sky impracticality (historically inducing in a certain species of self-hating philosopher the kind of it’s-not-science insecurities that lead to patently self-inconsistent theories as verificationism, not to mention the bevy of other views amounting to: “I’ve found the solution to all philosophical problems! There are none!” (Premise: any problem that threaten to limit the domain of scientific inquiry must not be a problem for science)).

So let me say this (first thesis): that you are a scientist does not mean he understands what your endeavor entails, any more than being a soccer player means understanding the physics and anatomy involved in the playing of soccer. That understanding requires reflection on the doing of science, not merely the accumulation of laboratory hours. Further, Ruse and others seems not understand or even be curious about issues in the philosophy of science or mind about which they are emboldened to spew by virtue of a kind of diplomatic immunity involved in calling themselves “scientist” (Ruse absurdly accuses Nagel, for instance, of being a “vitalist,” and assumes that physicalism is an easy solution to the mind-body problem–it would help him to familiarize himself with the literature and the fact that Nagel wrote the seminal anti-reductionist paper on the subject, What is it Like to be a Bat? If he thinks its claims are absurd, he ought to produce an argument, not a mere “that don’t sound scientific.”). So, second thesis: being a scientist does not immunize you from the requirement to think. Nor is being a scientist relevant to the soundness of your claims--it is not a slam-dunk in every science-related dispute. The (ad hominem) concept of that immunization is itself highly anti-rational (many scientists, of course, make no bones of their anti-intellectualism beyond the boundaries of the petri dish–and arguably this motivates some reductionist accounts).

I’m now going to apologize again for the intemperance of my screed, and I’d like to point out that I have a longstanding love of science (one of my undergraduate majors is the history of science). I have no truck with creationists/intelligent design adherents on the one hand or post-modern relativists on the other. But just as love of country entails honest self-critique … well you get the picture. This sort of credential-offering shouldn’t be necessary–it’s just a kind of preparation for being called the kinds of names that members of a loyal opposition get called. Suffice it to say that I simply believe scientism and anti-philosophical zealotry do nothing for science, any more than teabagging with a sign saying “freedom” does something for freedom. And in general, reductionism is just bad philosophy and has no bearing on the everyday practice of science or its esteemed status, except insofar as recognizes a limit to the domain of empirical scientific inquiry based on … whether or not the relevant data is susceptible to empirical scrutiny. Whether or not a neuroscientist believes that brain states are identical to mental states (as opposed to having some other sort of relation) will make no difference to his everyday work; but it will be relevant to his extra-curricular spoutings on God and Mind and Free Will and the rest–spoutings which which lead the dumb reductionist mythologies that pervade popular culture.

Episode 13: What Are the Metaphysical Implications of Quantum Physics?

Reading Werner Heisenberg’s “Physics and Philosophy” (1958), and talking about it with an actual former particle physicist, Dylan Casey.

What weird stuff about reality does quantum physics imply? Is Heisenberg (of the Uncertainty Principle fame) right that we need to reject “metaphysical realism” based on this very well established scientific framework? The discussion ranges over the uncertainty principle, relativity, wave/particle duality, Pre-Socratic metaphysics, why Kant is wrong about space, and lots of very weird things.

Plus, we spend far too much time talking about an article by Thomas Nagel about intelligent design; you can read that here. And the blog post by Brian Leiter that got us talking about it is here.
