ABSTRACT
The hypothesis of group selection fell victim to a seemingly devastating critique in 1960s evolutionary biology. In Unto Others (1998), we argue to the contrmy, that group selection is a conceptually coherent and empirically welf documented cause oi evolution. We suggest, in addition, that it has been especially important in human evolution. In the second part oiUnto Others, we consider the issue oipsychological egoism and altruism - do human beings have ultimate motives concerning the well-being oi others? We argue that previous psychological and philosophical work on this question has been inconclusive. We propose an evolutionary argumentfor the claim that human beings have altruistic ultimate motives.
