This quote by Kubrick is especially important:"The idea that social restraints are all bad is based on a utopian and unrealistic vision of man."
Interesting re Sowell.
It also accords so well with the visions of Postmodernist neo-neo-Liberals/ the Left. In fact many of the Left may hate their human nature and in turn hate themselves.
I have also thought that the Left is more pessimistic and self loathing than the Right who is more optimistic and realizes man is a flawed but heroic species which the Judeo-Christian tradition embraces more than Postmodernist philosophies.
