A couple other minor quibbles. First, the phrase structure grammar Pinker tentatively outlines is like none I've ever seen, or that any linguist would accept.I suspect that's because Pinker was trying to make PSG look more presentable and "natural" than thereal thing. Then there's his statement: "Language is no more a social construct than walking."Basically, he uses this outrageous and unsupported comparison to toss out any functional or socialaspect of a theory of language. This all stems from the rationalist ideal of social theories completely divorced from the environment they take place in.
Of course, for a staunchsupporter of the Cartesian Chomsky, also at MIT, none of this is really surprising. It's just ashame so many people are taken in by it.
Finally, note that Pinker is not a linguist, asmany people (at least one reviewer, anyway) seem to believe. He is a cognitive psychologist whosemain focus often seems to be in linguistics.
Thegerman translation (to which I refer) is very well done, too.
