Kuhn needs to be put into perspective, though (just as Feyerabend). See Chalmer's What is this thing called Science? for an introduction and much more material. And Gould has some good stuff (The Mismeasure of Man is challenging), but he's controversial, and some of his ideas (NOMA, ie the notion that religion and science are "non-overlapping magisteria") are, dunno, not convincing.
