And is this ignorance of philosophy a good thing or an argument against the importance of philosophy? There is more to the philosophy of science than positivism and Karl Popper you know. Maybe they should be learning Kuhn? Lakatos? Feyerabend?
Yes but they can be, and frequently are, excellent scientists WITHOUT having read the Open Society, the Republic of Science, the Structure of Scientific Revolutions, and so forth. Is it good for them to read those authors? Sure. I think they're beautiful arguments, and enjoyable. I also think they should take the time to read Shakespeare, Melville, and Charles Simic. Maybe watch 30 Rock. Meditate.
This is an obvious caricature of philosophy more reminiscent of first year undergraduate introductions to the nature of the philosophical enterprise than any serious contemporary thinker or line of inquiry.
Actually it's borne out if you browse through the table of contents of many major philosophical journals. Indeed, in the most recent issue of
Analysis there is an entire article devoted entirely to the global skepticism argument which I described.
Um, what? Peter Singer? Hannah Arendt? Untold other contemporary academics in universities all over the world? Aren't war, the holocaust, abortion or euthanasia substantive issues with an ethical dimension?
I said MANY, not ALL. I can certainly think of some who do engage, usefully, with substantive ethical questions, but that's a pretty small corner of philosophy.
Regarding war, or abortion, has there been a lot of progress on the philosophical front on those issues?
Besides which, the "abstruse meta-ethical questions" which other thinkers are dealing with provide the frameworks and debates that other philosophers which deal with contemporary issues are drawing on for their own studies.
They deal with frameworks that never seem to determine how anyone answers substantive ethical questions, and are frequently concerned with very fine linguistic distinctions that ultimately make no difference to actual arguments. Indeed, if anything, meta-ethics has tended to confuse the discussion, and knowledge of meta-ethical issues as discussed in academic circles is entirely unnecessary to understanding arguments about substantive ethical questions.
Ultimately you're not arguing against philosophy per se, you're arguing against a caricature of philosophy and its institutionalisation as a separate discipline in universities.
I'm raising the question, since I think it's a useful one. I have no conclusion on it.
With regards to the institutionalisation issue, at a certain level of abstraction disciplinary boundaries become arbitrary (the line between sociology, anthropology, and political science comes to mind here). But each institutionalised discipline reflects a distinct and fruitful, living tradition of inquiry. Philosophers deal with certain questions in certain ways, and nobody else does exactly what they do. No, they are not chemists or physicists or political scientists, but that's fine because they're dealing with questions that none of the members of those disciplines are able to contribute to.
That's not really a satisfying answer though. You've stated:
(1) Philosophy is an institutionalized discipline.
(2) All institutionalized disciplines reflect fruitful inquiry.
(3) Philosophy is a fruitful line of inquiry.
Begs the question, really.
And philosophers frequently draw upon other disciplines to answer questions. Indeed, I find philosophy to be more reflective of the state of knowledge in other disciplines, and reactionary to them, than anything else.
I've also never found that philosophers are particularly better at thinking about philosophical questions than talented people in other disciplines.
But really, philosophy doesn't need to have some kind of instrumental reason for existing. The fact that you don't think it's useful, or that contemporary philosophers don't get cited in economics papers or government reports, is irrelevant. Getting rid of contexts in which critical thought for its own sake is valued and encouraged can only be bad for society.
You begin by stating that we don't need an instrumental reason, but conclude your paragraph with an instrumental reason, and offer nothing in between.
In any case, I would hope that we encourage critical thought in every context. We don't need academic departments of philosophy for there to be critical thought.
There you go again taking it a priori that science has subsumed all inquiry.

That in and of itself is a philosophical assumption. I'm not out to convince you it's not a philosophical position without a lot going for it. Though I personally don't subscribe to it, as a man of science I encounter it frequently in people I work with and highly respect. It's been well defended and is quite popular. But like all philosophical positions, as useful, beautiful, or deftly constructed as it might be, it's based ultimately on assumptions that cannot be proven, and as such, it just logically follows that there will always be people who will build their worldviews on wholly different philosophical assumptions.
Fair enough. What knowledge has philosophy produced in the last 20 years?
I think this is something of a 'having only a hammer and seeing only nails' kind of issue. [...] To those who take the search for wisdom in verbal form as their quest, everything is philosophy. It's all relative to where you stand and what your needs are in this world.
But that's just my philosophy. %)

I'd completely agree with that philosophy, and so would William James.
But do I need to pay a tenured professor to teach a couple of graduate seminars on Carnap's theory of syntax for this?
i stopped replying to questions about the usefulness of philosophy. which might be a shame, upon seeing some beautiful answers given here.
but people that ask this question don't have 'the feel' for it, and in my experience, they never get it.
The institution of academic philosophy isn't immune to critical thought or evaluation. Nor should it be.
its in the nature of the question itself: usefulness. means to an end. everything is means to an end which is in itself a mean to another end, and so on. you don't stop. you don't distance yourself from what you are doing, you're doing and strictly speaking, without any philosophy, this constitutes cancerous growth. philosophy is THE end. its about stepping outside of the machine, and take a look at why are we doing this, and where it is going, and where should it be going? to do just that, you need to end it for yourself. you escape what you are doing through death for you. in Heideggers words; nobody can die your death for you. it is the locus of your ultimate freedom, and therefor, your ultimate responsability as well.
I don't think means and ends are mutually exclusive categories, and that the assumption that they are accounts for a lot of bad... philosophy concerning them, but leaving that aside and assuming the truth of your paragraph, why should we pay professors of philosophy to achieve this for themselves?
