Abstract

Psychological egoists deny that men ever voluntarily act to promote the interests of others as an end in itself or ever act in such a way that they have the same regard for others as they have for themselves. [...] This theory has a long history and was supposedly decisively refuted by Butler. Yet it continues to haunt the scene. I want, in the tradition of Butler but not in his manner, to try to set out a short snappy but definitive refutation of psychological egoism which will also show why it has such a hold on people.
