Carl Sagan Ann Druyan Quote

Taken together, the dramatic societal shifts – often in ten generations or less – provide a compelling refutation of the claim that we are condemned, without hope of reprieve, to live out our lives in a barely disguised chimpanzee social order. Moreover, the shifts are occurring so swiftly that they cannot possibly be due to natural selection. Instead our culture must be drawing forth propensities and predispositions that already reside deep within us.
