Butler's Stone

Abstract

In the eleventh of Joseph Butler's Fifteen Sermons we find his best-known argument against psychological hedonism. Elliott Sober calls that argument Butler's stone, and famously challenges it. I consider whether Butler's stone has value. In doing so I examine, and reject, two possible responses to Sober's objection. This involves, in part, discussing Lord Kames's version of the stone argument, which has hitherto escaped scholarly attention. Finally, I explain an important value of Butler's stone, which I have not found previously discussed. Butler's stone blocks an inference, persuasive to many people, which purports to show that we intrinsically desire only pleasure.
