In case you missed it, Leiter ran another survey, this one assessing which subfields are most important for strong PhD programs in philosophy. Epistemology came in first; details here.
I’m not surprised that epistemology is one of the top five, but a bit surprised it came in first. I see the discipline as focused in Language/Mind and M&E, together with Ethics (broadly construed). And I would have thought that L/M would win out over M&E by a small margin (and I wouldn’t have made any predictions about where Ethics would have been ranked)–that fits the story of 20th-century anglo-american philosophy at least through the 70’s, but maybe the revival of work in metaphysics, tracing to Kripke but having Lewis as more of a triggering cause, together with the explosion of interesting work in epistemology that is both post-Gettier and that has gone beyond the stale metatheory involved in the foundationalism/coherentism and internalism/externalism controversies, has changed the landscape. Perhaps. Though JFP ads don’t seem to suggest such, at least not in terms of raw numbers for each specialization. Perhaps, though, a more fine-grained analysis of what, say, the top 50 PhD programs have been hiring in would show M&E in ascendancy over L/M.
