Query: Opinionated

Too opinionated a book. Few believe the mind is a blank slate. But Pinker seems to believe the mind is a TV dinner, and that a chef in the kitchen (parents!) is an almost incidental redundancy.To take a trivial example to counter this, David Letterman once had on his TV show identical twins who only met in middle-age. Well, they weren't exactly identical, because one was quite fat, and the other quite thin!! Now if identical twins are so much alike that--as Pinker states--some of them (Pinker wants to give the impression that it's ALL of them) end up vacationing in the same spot, even if seperated at birth, certainly these two twins on Letterman would have had the same body build!!
