There are circumstances, such as living in a depraved society, in which it would not benefit someone to live virtuously, and it is reasonable to ask why human beings should commit themselves to virtue when the desired result, to flourish, relies on many factors that are beyond our control. 3 In addition to the contingencies of the world, there are contingencies of our psychology.

As Williams puts it, the Aristotelian view seems to presuppose an inner nisus to virtues, which is called into question by Darwinian biology, since it is ''an open question whether the evolutionary success of humanity, in its extremely brief period of existence, may not rest on a rather
