Characteristically nice post about the analytic-continental divide from Graham Harman HERE.
Whenever Harman posts on this issue I find myself agreeing with everything he says. With Harman I think it is much more healthy than not that there are different traditions, and that they remain different
In place of thinking the division should disappear, I would instead make the following claims: (1) an a priori unwillingness from members of one tradition to learn from members of other traditions is problematic, (2) almost equally problematic are people from one camp who are only open to people from the other tradition to the extent that those people articulate views that seem to support those of the supposed pluralist's,* and (3) whatever you think about the different styles, the thinkers covered by continental philosophers should be taught in analytic programs (especially German Idealism and 19th Century more broadly, but also the things Leiter derides).
I should note in passing that one of the things I like about Speculative Realism is that its main practitioners do not embody any of the above vices. Analytic and Continental describe first and foremost training regimes for academic philosophers. But at a certain point you should put on your big boy pants just try to do philosophy, which requires following the muse wherever she wants to take you.
Avoidance of the above vices is not accidental, since Speculative Realists reject two substantive positions at the heart of the most significant continental and analytic philosophers, positions that started with the Positivists and Heidegger, and that rise up zombie-like over and over and over again.
This becomes crystal clear if one realizes that the divide between analytic and continental philosophers is much less philosophically important than a couple of other deeper divisions (1) between anti-metaphysical thinkers and at least anti-anti-metaphysical thinkers,** and (2) between naturalists and non-naturalists.
Weirdly, analytical philosophy's founding sin was combining naturalism and anti-metaphysics and continental philosophy's founding sin was combining non-naturalism and anti-metaphyiscs! But naturalism is false (see Michael Ruse HERE) and anti-metaphysics is incoherent (read the early critics of Kant or Graham Priest for that matter!).
In analytical philosophy anti-metaphysics is where naturalism goes to, if not die, continue some kind of a zombie-like existence. This goes all the way from Marburg School Neo-Kantianism to Robert Brandom, currently holding the office of the last positivist (after Bergmann then Quine and then Rorty before him). Brandom-type Pittsburgh Hegelianiasm, for all of its manifest virtues, almost constitutively returns to the kind of view that Heidegger derides in his very first (emergency war) lectures, of the universe as some valueless hunk with humans (in the guise of social practice) guilding and staining it. This is properly neo-Kantian, not Hegelian, as is the quietistic anti-metaphysics*** that obscures the basic move.
But, on the contrary, in continental philosophy anti-metaphysics comes from the Heideggerian view that science itself is a founded mode over something anti-metaphysics phenomenology reveals to be more originary. So while analytic naturalism leads to anti-metaphysics (because one must deride as meaningless questions that the natural sciences cannot answer), continental anti-metaphysics leads to anti-naturalism.
One is actually tempted to join the two above observations to make the following sort of argument. Analytic philosophy shows that naturalism refutes metaphysics. Continental philosophy shows that the refutation of metaphysics refutes naturalism. Therefore naturalism refutes naturalism.
In any case, I raise my flag with anti-naturalist anti-anti-metaphysicians. We're a tiny minority in both analytic and continental philosophy. With the possible exception of a non-trivial set of Christian apologists (usually working in a dialectical setting horribly tainted by either fideism or its opposition, IMHO), analytical philosophers who are not anti-metaphysicians are almost all naturalists (argument above notwithstanding)! And, with the notable exceptions of the Speculative Realists, Deleuzians, and some other heroic figures, continental philosophy by and large continues to chug along wearing the same old phenomenological straightjacket, with its attendent quietism and other forms of recycled neo-Kantianism. Note that this is perversely a straightjacket that any proper reader of the German Idealists would have thrown off long ago. Well with Quentin Meillassoux and Graham Priest's readings of this tradition,as well as Graham Harman's indefeteagable labor, at least some of us have begun to wiggle our way out of the damned thing.****
*It's very hard not to fall into this trap, perhaps impossible. Some strategies for an analytic philosopher who wants to be a "pluralist": (1) You must, must, must avoid the temptation to use your continental friends to give yourself a patina depth by simply adding a footnote when one of those continental friends tells you that someone you've never read has an idea kind of like yours, (2) You must go to talks about thinkers you don't like and be vigilently open to the idea that informed people of good will disagree with you about your assessment, (3) As much as possible, maintain an active reading life that has nothing to do with whatever current project on which you are working; this helps in all sorts of ways.
**The distinction between anti-metaphysics and anti-anti-metaphysics should not be confused with the distinction between anti-realists and anti-anti-realists. John McDowell is both an anti-metaphysician and an anti-anti-realist. See the next note.
***John McDowell is, like most continental philosophers, actually anti-metaphysical and non-naturalist. Brandom claims to be non-naturalist, but he really is not, at least in the important sense that the early Heidegger adumbrated. This is the entire reason, I think, that Crispin Wright famously put John McDowell down as not really being an analytic philosopher, but (as far as I know) has never said anything remotely similar about fellow Pittsburgh Hegelian Robert Brandom.
****Just because nothing above makes this sufficiently clear- I think Heidegger is one of the most important five philosophers in history and also that Brandom is easily in the top five of living philosophers.]
