David Theroux of The Independent Institute reports that Alvin Plantinga, the Jellema Chair in Philosophy at Calvin College, has won the Nicolas Rescher Prize for Contributions to Systematic Philosophy, awarded by the University of Pittsburgh's Department of Philosophy. You can read David's announcement here.
Plantinga has been very active in philosophical discussions of the rationality of religious belief, and has participated in public forums with some well-known skeptics. Some of his arguments seem rather strange to me (for example, he has argued that if evolutionary theory is true, it is a disaster for naturalism), but his work on the so-called "ontological proof" for the existence of God has kept an otherwise arcane logical problem on the front burner for many years now, and has prompted a wide variety of responses from the philosophical community. He has written extensively on the concept of epistemic warrant, and has deployed his version of it in defense of the rationality of religious belief. You can find links to many of his papers and books at The Independent Institute's announcement of the prize linked to above.
