I just read a rather silly review of my book Inborn Knowledge by Peter Carruthers. Was he even trying to get the point? I make it a policy not to reply to reviews, especially silly ones, but there is a point I would like to correct because it concerns a friend of mine: Jerry Fodor. Carruthers bizarrely interprets my observation that major twentieth century philosophers have not been much concerned with questions of innateness as some sort of tacit suggestion that Fodor is not a major philosopher. I certainly think he is, and he has written on innateness; but that does not contradict the fact that Frege, Russell, Wittgenstein, Moore, Carnap, Kripke, Quine, Davidson, et al had little or nothing to say on the subject compared to earlier philosophers. The rest of the review is at the same level, I’m afraid.
