The argument is absurd. Claiming that universities are "poisoning minds" by teaching Aristotle and Descartes in 101 Intro to Philosophy courses is just silly. Those same universities teach modern philosophy courses that deal with the intersection of science and philosophy – judging by my one or two philosophy friends, philosophers are much more interested in the practical discoveries of psychology, math, and science…

Have you read Pearl and Kahneman? I do not think you have comprehended Luke's perspective. Your rebuttal is largely demonstrating the behaviors he is, aptly in my opinion, criticizing. Your overly romantic definition of philosophical inquiry would relegate it to a metaphysics of the unknown at best, mysticism in the cloak of learned language at worst. I cannot conceive of how you interpret any of what Luke is saying…

I do not speak for unalone.

Personally, I see that lukeprog demonstrates an anti-intellectualism when he states, 'Another paper arguing about the definition of "knowledge"? No thanks.'

I'm trying very hard to not be rude and laugh at the ridiculousness of eliminating certain philosophical studies/classes that lukeprog suggests.

Let me first say I lean more towards unalone's thoughts on this matter. But essentially, I believe what is going on here is an ideological battle that has occurred many times in the history of Western philosophy (to quote a certain someone). That is, what is the purpose of philosophy and who should it serve?

Philosophy, if it perfected anything, is the art of meta and intertextuality. Yes, even the latter. Read Euripides.

Philosophy has mathematical philosophers, it has scientific philosophers, it has gnostic philosophers, it has theological philosophers, and a long list of etcetera. But to narrow it down ideologically to one single thing the way lukeprog desires, is a foolish thing and unproductive to philosophy at its core. Why? Because any student of philosophy will tell you that asking 'What is knowledge?' is philosophy. Epistemology (the study of knowledge) is an important part of philosophy because philosophy is very much tied to culture as it is to history as it is to rationality and logic. To reduce philosophy to only its practical components and, this is the important part for me, oppressing certain philosophies is no better than trying to erase part of someone's culture.

But all this has already been discussed in philosophy with regard to Bertrand Russell's approach. The fact that all of us are having this discussion is philosophy. Some philosophies do not want to be science, and no one should force them to.

If you watch The Philosophers' Football Match (http://www.youtube.com/watch?v=ur5fGSBsfq8), for example, there is a meta discussion and intertextual reference going on that is never mentioned, but it exists. It gives as much insight into what philosophy is for each country as a study on truth tables or logic.

This is a great statement, because it points to the fundamental problem with Descartes' legacy: "His philosophical results are now largely a historical marker on a road to nowhere. His formalisms are still used by every human practitioner of math from elementary school students on up." As if his "formalisms" could stand on their own without the philosophical foundations of his entire system. And yes this is what mode…

In what way are the notations Descartes introduced dependent upon his philosophical views?

"And finally we're left with a weird, cobbled-together Popperian/Kuhnian pragmatism that long ago gave up on "certainty" or "clarity" and settled for "less wrong."

What surprises me is that people are so willing to assume that such certainty is desirable. That quantified symbolic logic is both primary and desirable, and that probabilistic reasoning is at best an occasionally necessary but highly suspect tool.

What a sadly limited universe of discourse that is, being forever circumscribed by Godel. It is fortunate that we don't exist trapped in it. I see no reason to intellectually place myself in the same prison.

"Personally, I see that lukeprog demonstrates an anti-intellectualism when he states, 'Another paper arguing about the definition of "knowledge"? No thanks.'"

I see how this criticizes one branch of intellectual thought within one discipline. I don't see how it is anti-intellectual. Luke runs the singularity institute, an organization dedicated to a highly specific and speculative conception of humanity's future (and a mistaken one in my opinion). You're trying to convince me this is not an intellectual activity? That he's anti-intellectual? This is rubbish, and you're just being defensive because he's attacking a specific set of ideas you value.

"Epistemology (the study of knowledge) is an important part of philosophy because philosophy is very much tied to culture as it is to history as it is to rationality and logic."

If you had read Pearl, you would understand that it is foremost, an epistemological theory. Luke is not rejecting the study of knowledge as a whole, he is bemoaning that only computer scientists and statisticians are learning a theory of knowledge that he believes supersedes the majority of historical philosophical thought on the matter. I strongly agree with him on that point. I think there's still value in teaching Aristotle et all, but that exactly as you say above, the perspective should be historical.

I agree that Luke is being a bit hyperbolic in the language of his post, but the vast majority of people responding here do not understand what he is advocating because they simply HAVE NOT READ THE BOOKS HE IS SUGGESTING YOU READ. And so they attempt to argue against his suggestion, not even knowing what motivates it or its merits.

Sure -- Descartes mathematics in the abstract are surely not dependent on his foundationlism/rationalism. As such they are merely tautological. But the science that deploys that math in pursuit of practical knowledge is.

Agreed that 'certainty,' at least the kind that Descartes was advocating, is an abstraction in search of a definition, and as such not desirable. Godel and incompleteness is just one species of the problem. This is where I would rather see a reformed Baconian science, tempered with (rather than utterly rejecting) an Aristotelian view which had a more sophisticated language for dealing with ambiguity and the fluid borders between substances. Our physics has advanced far beyond simplistic atomism, why can't our philosophy of science?

Popper and falsification is a good rear-guard action against skepticism and making unwarranted philosophical leaps within the Cartesian taxonomy, but why can't we question the taxonomy itself? There are plenty of good starting points -- Whitehead and Bergson come to mind, as well as an open re-examination of medieval and pre-socratic philosophy, as Heidegger does in the Question Concerning Technology. On and on. It's not as if no one is asking these questions or refining philosophical language to deal with them -- it just seems that the scientific community would rather declare its own sovereignty and emancipate itself from first-order questions once and for all.

Poor Plato, it seems the only sin of which he is accused, and for which he is pilloried, is that of having lived a long time ago. But for all of the comments, I can find no arguments against any thesis in Plato. And this is noteworthy. Not just because it indicates that Plato is here just a straw man and that few (if any) of his assailants here have read him, and so of course, have no grounds to criticize. But more importantly, because, Plato does not have some set of theses which even could be toppled or made irrelevant. Plato does not work like that. Philosophy does not (usually) work like that. Plato does not promulgate, he investigates. He is still taught not so much because his answers are still relevant, but because his questions are. The original article implicitly acknowledges this point when the author guesses that philosophers trained in "modern" disciplines might "get farther" than Plato on the big questions—to which one might reply: and how shall they know the big questions?

Someone here pointed out that this wholesale dismissal of philosophy is a category mistake (a welcome reference to Aristotle), and I agree. If you will forgive my speaking too broadly, the difficulty many non-philosophers seem to have with philosophy is simply that they do not know what it is—and more importantly, that they have never done it. I do not fault them for this (and I'll readily admit that our academies are very much at fault here, as the professionalization of philosophy has done no favors for philosophers or non-philosophers) but one ought to have, if not enough humility, at least enough love for truth to motivate silence, study, or wonder in the face of the unknown—not slander.

Philosophy (and especially Plato's philosophy) is not the sort of thing for which one uses a textbook. If you recall the Phaedrus (and if you don't recall the Phaedrus, you probably should not be commenting on philosophy) you'll remember that Plato has an argument against books. He worries that books will codify doxa in such a way as to stifle inquiry—a worry that was clearly warranted, as evidenced by this thread. Thus he preferred dialogues to dissertations, and precisely because the individual appropriation of knowledge, and the harmonizing of the person with reality, is what really counts—not knowing (or believing) a bunch of stuff. It is important to remember that Plato, even when making myths, is imminently and always practical.

Those who advocate that contemporary science is better equipped than philosophy to answer the big questions, because science "examines reality, etc." fail to recognize that "reality" itself is big question. In my own experience, I have often found it amusing how quickly some "scientists" dismiss philosophy, while I've met very few philosophers who would do the same for science. It is fine if one wants to ignore philosophy, but it is hubris to dismiss it simply because it does not do what one wants it to do.

First, Goedl's Incompleteness Theorem comes out of philosophy through the early 20th century's focus on logic and positivism. I'm sure you consider that well-defined, non-trivial, and correct. Second, there is no requirement for philosophers to "settle things", and it's undemonstrated that, in order to settle things, the answer must be well-defined, non-trivial, and correct. One example of that is Wittgenstein's dism…

I don't consider Godel's theorem to be philosophy. Its status is similar to Cantor's theorem stating that reals are uncountable. Surely is inspired by philosophy and has philosophical consequences, but it is a part of mathematics. Trivia: Godel used the Chinese remainder theorem in his proof http://mathoverflow.net/questions/19857/has-decidability-got... . I acknowledge that philosophy can be inspiration for mathemat…

You might not, but philosophers certainly do--I learned it in my philosophy classes on logic. I also learned there about Cantor's diagonalization proof. More generally, in the early 20th century there was a huge overlap between mathematics and philosophy. You had Russell and Whitehead's Principia Mathematica, you had the Vienna Circle, you had Carnap and logical positivism... It's really not possible to cleanly categorize Goedl's proof into either math or philosophy--they weren't disjunct categories then, and they're not now, either. More importantly, if you approached any of those figures and asked whether they were separate things, they'd have thought the question nonsensical. Philosophy was, and still is, the home of logic in the academy, and the fact that logic and math frequently seem like different sides of the same coin doesn't settle the issue either way.

Philosophy and I parted ways in college when it became apparent that my own opinion meant less than someone else's. I look at philosophy as it's taught now like an introductory art class, where you learn how to draw lines and circles and shade things. Once you have a certain repertoire, focussing purely on technique becomes a waste of time, sort of the antithesis of art. Modern philosophy is touching things up in pho…

Yes, this is quite an interesting feature of philosophy, and I would say, an interesting feature of the world: that some opinions are more valuable than others.

Nietzsche's argument against the existence of God has become a common argument against any and all truth. Zarathustra tells his disciples: "If there were gods, how could I stand not to be a god! Therefore there are no gods."

Therefore do not study philosophy.

I'm not sure what that means. Dogs and apes and all social creatures have an innate sense of morality. They react emotionally to transgressions and punish transgressors. Nature has evolved that, in humans it has created certain rather strong thoughts and feelings on the subject. So in that sense nature does care. Different systems of morality are also going to lead to very different societies of varying effectiveness…

Here is my favorite example showing that effective societies in other species need not be ones we like. Our closest relatives are chimpanzees. Their sexual strategy is to produce lots of sperm and have lots of sex. The average chimpanzee male has sex an average of once per hour. (This is the 24 hour average.) About 1% of the time, the female attempts to resist, this does not bother the male. The result? The average c…

I missed the step from 'evolution has endowed social animals with a native sense of morality' to 'morality must be based solely on that sense, or on chimp morality'.

Social animals have innate behavior patterns that let them cooperate. Humans complement those with concepts like Kant's categorical imperative or Rawls's theory, thinking about them and teaching them to succeeding generations. No contradiction.

Main thing is the need for a moral code flows naturally from the need to cooperate, prisoner's dilemma situations etc.

In general, repugnance is not always a good guide to morality, a lot of past and present civilizations do things which might seem repugnant to us but aren't necessarily immoral. Although abhorrence to things like rape is pretty universal.

(humans have pretty odd sex lives and hangups about them. If we ran around naked and had sex numerous times a day rape might not be considered as big a deal.)

> Philosophy's purpose is to search not for an answer to the surface questions (and when you're doing it right, everything becomes a surface question) but to dive deeper into questions of what lies beneath those questions, what assumptions we make when we use certain words or claim certain beliefs.

I really see this as a problem. It should be possible to teach critical thinking with more engagement with the world. Anyone can poke holes. It's much harder and more worthwhile to submit patches.

Reminds me of something I recently read:

>If you had gone to Epictetus and said, "I want to live a good life. What should I do?" he would have had an answer for you: "Live in accordance with nature." He would then have told you, in great detail, how to do this.

>If you went to a twentieth-century analytic philosopher and asked the same question, he probably would have responded not by answering the question you asked but by analyzing the question itself: "The answer to your question depends on what you mean by "a good life," which in turn depends on what you mean by "good" and "a life." He might then walk you through all the things you could conceivably mean in asking how to live a good life and explain why each of these meanings is logically muddled. His conclusion: It makes no sense to ask how to live a good life. When this philosopher had finished speaking, you might be impressed with his flair for philosophical analysis, but you might also conclude, with good reason, that he himself lacked a coherent philosophy of life.

There is a line of philosophy, particularly popular among atheists and other people who like to call themselves rationalists, there is is some absolute morality which can be justified on the basis of the kinds of issues that you're talking about.

Just coincidentally, most people who believe in that come up with something like Western morality.

Now I grant, our desire for morality is indeed evolved. It is as much a part of the fabric of who we are as, say, the ease with which Stockholm Syndrome can set in to quickly adapt us becoming slaves. (Historically a very useful reaction to have from time to time.)

My point is that any attempt to justify current moral beliefs on evolution, game theory, and some sort of absolutes, is fundamentally flawed. We are equipped to have moral reactions. We are trained to have particular moral reactions. But we have no evidence that our current moral fashions are in any real sense fundamental.
