> something that humans have been discussing in a rigorous way for thousands of years

That's my point: most philosophy is not rigorous. It might have a veneer of rigor but most of it is nonsense because it starts with false premises. Garbage in, garbage out.

[knightoffaith]

I don't think you'll change your mind on that regardless of what I say, so I'll refrain from engaging that particular point.

What do you think is the relevant difference between philosophy and music that makes it silly to study the former formally but not the latter?

[lisper]

I don't think it's silly to study either one. What I think is silly is the idea that philosophy is an intellectually rigorous field, that its practitioners generally deserve to be held in high regard, that it makes sense to have departments of philosophy in universities. This was not always true, I think it has become true gradually over the course of the last 100 years or so. I think that science has subsumed philosophy in exactly the same way that chemistry subsumed alchemy and astronomy subsumed astrology.

[knightoffaith]

We were originally talking about how many people who weren't philosophers enjoyed philosophy---what happened to that?

But whatever, we can set that aside if you'd like, I'm kind of curious to hear - what do you think was lost in the last 100 years ago? I'm a bit surprised to hear that, I would have thought you would say that we got more rather than less rigorous post-Frege. What do you think of philosophers today who specialize in studying the history of philosophy today, or philosophers who specialize in specific periods of pre-20th century philosophy (ancient philosophy, medieval philosophy, etc.)? Or specific pre-20th century philosophy?

And I have to ask, since you're a big fan of Popper---what do you think about Kuhn and Feyerabend? Quine (particularly the Duhem-Quine thesis)? Post-Popperian philosophy of science in general? All just nonsense?

(You don't have to address every question if you'd rather not take the time.)

> how many people who weren't philosophers enjoyed philosophy

No, we were talking about (or at least I was talking about) how many people get value out of philosophy who don't practice it, at least as amateurs. Is philosophy like music or is it like yoga? I'm on team yoga.

> what do you think was lost in the last 100 years ago?

It's not what was lost, it's what was gained. And what was gained is major breakthroughs in areas of science that allows science to answer questions that were traditionally the purview of philosophy. These include evolution, molecular biology, the theory of computation, quantum mechanics, and neuroscience.

> what do you think about Kuhn and Feyerabend?

I don't know much about Kuhn. I read "Against Method" a long time ago and it seemed like total nonsense to me at the time, one of the things that convinced me that philosophy as an area of intellectual inquiry was bankrupt.

> Duhem-Quine thesis

Yes, I think this is pretty self-evidently true. A finite amount of data, which is all we can ever have, will always be consistent with an infinite number of theories.

> (You don't have to address every question if you'd rather not take the time.)

I'm actually finding our exchange very interesting and worthwhile. You're keeping me on my toes.

Well, I've said that there are plenty of people who don't practice philosophy who enjoy books of philosophy taken seriously by philosophers. You responded that these people enjoy discussing philosophy, the implication being that these people are practicing philosophy. And I responded in turn that these people are no more practicing philosophers than people humming tunes are practicing musicians---so it's not clear what the relevant distinction between music and philosophy is supposed to be with respect to its enjoyability beyond practitioners of the discipline.

How much of Plato's dialogues do you think were about these things? I don't deny that what used to be called natural philosophy is now just science, but it's rather extreme to say that the sciences have conquered everything philosophers were in the business of doing. And Plato isn't just some random exceptional example; I'm sure you're familiar with Whitehead's "footnotes to Plato" quote.

>I read "Against Method" a long time ago and it seemed like total nonsense to me at the time, one of the things that convinced me that philosophy as an area of intellectual inquiry was bankrupt.

Feyerabend is rather extreme, but I'm curious why you think it was totally nonsense.

>Yes, I think this is pretty self-evidently true.

And do you see the problem this poses for Popperian falsificationism? More generally, philosophy of science, beyond just Popper, is a good example of meaningful work done in philosophy.

> it's not clear what the relevant distinction between music and philosophy is supposed to be

Music can be enjoyed by someone who never practices it at all, not even humming or singing in the shower. Yoga cannot. You have to do yoga to get any value out of it at all. No one gets any benefit out of simply watching people do yoga.

My claim (and it's an empirical claim -- I might be wrong, but you'd need actual evidence) is that philosophy is more like yoga than music. Almost no one gets value out of it without actually participating in some way. (I hedge with "almost" because you might be able to find a few weirdos out there who really do enjoy reading Wittgenstein for its own sake and never engaging in philosophical discussion, but I'd be surprised if there are more than, say, a few dozen such people on the entire planet.)

> it's rather extreme to say that the sciences have conquered everything philosophers were in the business of doing

I'm not saying that. I'm saying that science has conquered a lot of what philosophers were once in the business of doing, and many of those things were things that people used to believe (and some still believe) were inherently beyond the reach of scientific inquiry, with human consciousness and Dennett's "Consciousness Explained" being my poster children. I'm not saying this project is complete, I'm predicting that science will continue to make progress monotonically until all that is left for philosophers is the Philosophy of the ever-shrinking Gaps.

> Feyerabend is rather extreme, but I'm curious why you think it was totally nonsense.

I'd have to go back and re-read it. It has been many decades and I don't remember any of the details.

I can tell you two things though: First, I was turned on to Feyerabend by someone I deeply respect and so I was predisposed to like him. And second, looking over the Wikipedia article on him I can see right away why I don't:

"Feyerabend's most famous work is Against Method (1975), wherein he argued that there are no universally valid methodological rules for scientific inquiry."

That is flat-earth kind of wrong. There is at least one obvious universal methodological rule for scientific inquiry, and that is the one voiced by Feynman: any theory that is inconsistent with experiment is wrong.

> And do you see the problem [Duhem-Quine] poses for Popperian falsificationism?

No. I can see why someone might think it poses a problem, but I don't see any actual problem.

BTW, note that even if DQ poses an actual problem for Popper, all that would do is falsify Popper as a theory of why science is effective. It would have absolutely no impact on the manifest fact that science is effective. That fact alone casts some pretty serious doubt on DQ being a problem for Popper because the only way it could possibly be an actual problem for Popper is if Popper is correct :-)
