No philosopher worth her salt would try to answer this question as formed because of the large number of buried assumptions in it that presuppose the form of the correct answer, and that answers not meeting that form are, by definition, incorrect. Your question is a sophisticated version of "have you stopped beating your wife?"

Let's look at this question: What "truth" has mathematics itself produced from that search which is well-defined, non-trivial, and correct? Is it a loaded question? I think it isn't, and it has a lot of valid answers. Here are some recent ones: http://en.wikipedia.org/wiki/List_of_unsolved_problems_in_ma... . Why the corresponding question for philosophers should be loaded? Are they exempt from settling things?

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 dismissal of a significant number of previous philosophical problems as empty language games. The field advances; it doesn't "settle things" in the sense that mathematics lays down proofs upon which the edifice later builds. Sometimes the advance is dismissing large portions of what went before as mistaken.

> Notably absent from this guy's syllabus is anything concerning ethics, morality, values, or right and wrong. That's because all morality is relative, one of the few things philosophy got right.

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.

> Dogs and apes and all social creatures have an innate sense of morality.

Yes, but not the same morality. The point is that all morality is relative, and your example supports the thesis -- dog morality is not chimp morality, which is not human morality.

> 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.

Absolutely false. You're imagining an intent in nature for which there is no evidence whatsoever.

Your child is starving, and a dolphin is available as a food source. You have to choose which moral standard to adopt -- yours, or the dolphin's (another thinking creature). They aren't the same, indeed they absolutely conflict.

> So in terms of outcomes nature cares as well.

You really need to expel this idea -- it's quite false. Nature is morally neutral, and does not care.

> That's because all morality is relative, one of the few things philosophy got right. As far as I know, there is no consensus in the philosophical community that relativism is right. In fact, my impression is that there's a stigma against relativism, as it's hard to come up with a satisfactory relativistic theory. For example, if relativism is true, it might be the case that we can't judge other societies or other t…

>because nature isn't a thinking thing that can care. This isn't commonly accepted even now. Many people think that good things happen to good people because nature/god cares.

> Many people think that good things happen to good people because nature/god cares.

Any realistic, objective sampling of human experience instantly falsifies this claim. The correlation coefficient between "good" behavior and "good" outcomes (and the reverse) is precisely zero.

To many people, the single most annoying thing about science is that it quickly demolishes such romantic notions, using logic and objective statistical sampling.

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 as being even covertly anti-intellectual. You appear to be projecting your own world view and social groupings onto this topic, and presupposing some conflicts between them.

This continuum of deeply inscrutable pure truth pursued by inquiry at one end opposed to surface practical technical solutions developed by practitioners at the other is an artificial perspective. There is no opposition between these things. Often both are advanced in the same moment, and by the same work.

Descartes himself is an excellent example: he was intensely focused on devising exact formal methods. 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.

I strongly encourage anyone who finds this discussion interesting to read the mentioned books by Pearl and Kahneman. They have transformed my thinking more than anything else I have learned in my entire life up to this point. These aren't mere technical tools, or interesting empirical results in some corner of practice.

I don't know of a short introduction to Kahneman's work, but the epilog to Pearl's book[1] is a short read and touches on the philosophical side of his thinking.

Kahneman is an easy and very enjoyable read, but do not underestimate the value of learning your mental model of your own cognition has no clothes.

Pearl's basic concepts are accessible, but finishing the book will require some effort for most, as will considering the implications rigorously. It's worth it however, because he provides a compete theory of knowledge that is both philosophically rigorous and algorithmically exact. His Turing Award lecture[2] should give you some sense of how staggeringly broad the implications of his formalism are.

While I agree that philosophy has the ability to ask good questions, unfortunately it does not seem to be able to answer those questions in any meaningful way. Science also has the ability to ask good questions, but it knows how to answer them in a meaningful way (at least good science does). By meaningful, I mean provably true. Philosophy is very happy to take untested opinion as true. Which is provably dangerous. I…

I think that kings ought to be philosophers, metaphorically speaking: I trust politicians who prove they have at least some understanding of philosophical inquiry much more than I trust the ones who are skeptical. But philosophers themselves shouldn't be kings: hell, how would you pick the one to rule over the rest of them? The best philosophers are frequently the most controversial: the controversy surrounds them be…

"Here's the thing with "provably true" that I find worrisome: the process of proving something as rigorously as scientific research demands it is so slow, so painstaking, that if we relied entirely on science to inform our knowledge, we'd lose out on literal millennia of human experience."

"Philosophy is a much, much broader technique; in fact, it specializes in finding ways to look at even broader questions in exquisite detail. That makes it a very impractical tool if you're trying to, say, build a space ship. But it makes it a far more useful tool if you're trying to understand things as complex and abstract and subtle as, say, questions of how we acquire knowledge, or what it means to think."

To be blunt: you need to read Pearl (and Kahneman), because it is clear you are not familiar with the ideas you are arguing against.

Many philosophers have questioned the scientific definition of "correctness". For example Heidegger who argued that scientific truth is an approximation and measurement of things that we already presume to exist. These discoveries may be correct, and they may be true. But what about the more primordial truth (i.e. being) which we take for granted before we even begin a scientific inquiry? This is what he investigates…

> Many philosophers have questioned the scientific definition of "correctness". This concisely and aptly summarizes the reason for philosophy's low standing among intellectual disciplines. Philosophers are manifestly unqualified to debate the scientific definition of anything, much less "correctness". Beyond this, a suitable definition is too short to be of interest to a philosopher, someone for whom the number of wo…

Where to begin with this?

This is naive scientific triumphalism of the first order, utterly illiterate with regards to the philosophical foundations of science, the rigorous and multi-layered debates over the status of scientific statements that have been ongoing for centuries to the present day: from Bacon, Gallileo and Descartes (with deep roots in Lucretius, Plato, Aristotle, Thomas, Epicurus, Heraclitus) through Spinoza, Leibniz and Newton himself, on into such titans as Kant, Hegel, Husserl, Bergson, Heidegger, Russell, Whitehead, Popper, Kuhn, Lakatos and Quine.

And yet! And yet! It was all so simple, gads and forsooth!!

I give you the final word, gentle reader, it was all for naught, these men with their devotion to rigor and clarity of thought, their conversations spanning centuries, their volumes of pointless abstraction, Hegel with his historicism and Kant with his categories, cynical Kuhn and his paradigms, pragmatic Popper with his Worlds 1 and 2, Whitehead with his ingressions pseudo-Aristotelian speculations and Bergson teasing out duration and intuition.

Throw out your Rutledge Encyclopedia: and behold the simplicity they all failed to grasp:

A scientific idea is "correct" if it can be successfully compared to reality.

How hard is that indeed!! Not hard at all. Simplicity itself, devastating in its directness and comprehensive competence, lovely in its completeness. Centuries of debate quelled in a single utterance. Well done.

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 mathematics, but this is rather unsatiating, as very many things can be.

In the meantime, I found a very good defense of philosophy here: http://www.ditext.com/russell/rus15.html

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 modernity after Hume did -- take Descartes' project forward long after the core assumptions had been completely undermined.

In many ways the history of modern philosophy since has been a quest to re-ground the Cartesian project with the kind of confidence he promised, and a succession of regressive rear-guard actions taken against the encroaching skepticism that threatened the entire enterprise at every turn. 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."

No wonder philosophy is held in such low regard in scientific communities. It has done science no favors whatsoever in the last century, other than to progressively undermine its naive epistemological assumptions and redirect it back to some kind of Formal Realism -- at which point the scientific community yells "remember Galileo!!" and runs the other direction.

It's a sad state of affairs when we can't distinguish between the salutary philosophical insights of Aristotle and religious tyranny. It's going to take a long, long time to recast the entire narrative to where the two points of view can inform each other once again.

> A scientific idea is "correct" if it can be successfully compared to reality. But this is similar to saying what is real is what corresponds to reality. Do you see the circularity here?

Oh, come on. This is beneath you surely. Where are these "philosophers," this monolithic horde of abstraction-loving pinheads stuck in the 15th century, too benighted to see the Real Truth right under their noses, too stuck in debates over definitions to think practically about application and science??

You have a cartoon version of philosophy in your mind that is in sore need of remediation. These are precisely the kinds of questions that philosophers have been utterly preoccupied with for centuries. As if Bradley, Dewey, William James, never existed! As if the very idea of a pragmatic, "reality-based" science had not been proposed and debated rigorously for decade upon decade.

As if the subject-object problem wasn't at the core of the foundations of modern science!! Far from being some late, decadent conceit of a handful of disconnected postmoderns, the problem of objective knowledge is at the very core of modern science, at its very foundations, on to the present day.

Have you read a single volume of philosophy in the last decade? Are you not aware that the Grand Poo-Bah of modern philosophy of Science, Popper himself, redefines "Objective Knowledge" to deal with that very problem?

If you are content with a naive, self-contained scientism that remains dogmatically immune to philosophical critique, that's fine. You're certainly not alone. But let's dispense with the sweeping generalizations that have no bearing whatsoever on the reality of the history of philosophy, science or ideas in general.

possibly we shouldn't anthropomorphize nature. she hates when we do that. And it may be be creating barriers to understanding. perhaps one should substitute 'is a useful construct for understanding nature' for 'nature cares'.

I think the one thing that set me off in the original comment is that morality is a 'human invention'. A more complete picture would be that humans, dogs, and apes are a creation of nature, which has endowed them with a sense of morality. Not one that is consistent or infallible, just as your sense of balance doesn't always correctly tell you what is up and what is down, but a sense nevertheless.

In physics, referentials are relative. We don't say, let's expel the idea of referentials. There is no one absolute referential, but the concept of a referential is a useful one in a variety of contexts and worth developing. No one physical theory is final or complete, but some are more useful than others.

As your example notes, we cannot avoid acting, so thinking about the best ways to act is a useful project. Saying "it's all relative and nature is morally neutral, so I can do and justify whatever I want" is a moral choice, but not necessarily the one likely to lead to the least conflict.
