  A common objection to psychological egoism, made famously by Joseph Butler, is that I must desire things other than my own welfare in order to get welfare. Say I derive welfare from playing hockey. Unless I desired, for its own sake, to play hockey, I would not derive welfare from playing. Or say I derive welfare from helping others. Unless I desired, for its own sake, that others do well, I would not derive welfare from helping them. Welfare results from my action, but cannot be the only aim of my action.
