They are:  Jonathan Dancy ("Research Professor" at Reading; also Professor at UT Austin); Miranda Fricker (Sheffield, but who is moving to CUNY); and (as a Corresponding Fellow), Judith Jarvis Thomson (emerita, MIT).   In addition, the political theorist Michael Walzer (emeritus, IAS) was also elected a Corresponding Fellow.

UPDATE:  Philosopher Rob Stainton (Western Ontario) writes:  "Robyn Carston, a linguist but also a very influential figure in empirically oriented Philosophy of Language, was also just elected to the British Academy. She's been one of the key figures working on the Semantics-Pragmatics boundary since her pioneering work in the 80s."
