Abstract

This paper compares human diversity with biological diversity generally. Drawing on the pluralistic perspective on biological species defended in earlier work (2002, chs. 3 and 4), I argue that there are useful parallels to be drawn between human and animal kinds, as there are between their respective sources in cultural evolution and evolution generally. This view is developed in opposition to the insistence by sociobiologists and their successors on minimizing the significance of culture. The paper concludes with a discussion of the relation between cultural difference and individual difference, and the relation of the latter to conceptions of human freedom.
