Abstract
This paper discusses psychological hedonism with a special reference to the writings of Bishop Butler, and Elliot Sober and David Sloan Wilson. Contrary to philosophical orthodoxy, Sober and Wilson have claimed that Butler failed to refute psychological hedonism. In this paper it is argued: (1) that there is a difference between reductive and ultimate psychological hedonism; (2) that Butler failed to refute ultimate psychological hedonism, but that he succeeded in refuting reductive psychological hedonism; and, finally and more importantly, (3) that Butler’s criticism of reductive hedonism can be used as a stepping-stone in another argument showing the implausibility of ultimate psychological hedonism as well
