Since it came up in the comments on the previous post, what about language requirements? My own view is that they're useless in Philosophy as a departmental requirement. To explain: students working on dissertations on, say, Aristotle, certainly need to acquire a serious command of Greek, whereas students working on, say, deflationism probably have no use for any foreign language at all (they'd be better off learning more logic). So students working on dissertations in areas which require work in foreign languages should be required to acquire them at the level appropriate for their work. But these are matters for a student's dissertation committee to decide. Foreign language competence should not be regarded as a requirement for advancing to the dissertation (or "prospectus") stage.
In other words, the old school line about how working knowledge of a foreign language is essential to doctorate-level research is bunk.
