It is widely thought among philosophers that Joseph Butler's criticism of psychological egoism in his Sermons is, in the words of A.E. Duncan-Jones, 'the classic refutation of it.' Indeed, no less a philosopher than David Hume restated and put forth Butler's central argument against hedonistic egoism - without due credit - as part of his own critique. Yet recent commentators have begun to question Butler's arguments, albeit usually with sympathy and in the hope of saving what they take to be (...) his insights. I propose to focus on Butler's main objection to hedonistic psychological egoism, to show how and why it fails to refute plausible forms of the thesis, and briefly to indicate why philosophical attempts to disprove this theory of motivation are misguided.

It has become increasingly common recently to construe human natureas setting some pretty stringent limits to moral endeavour. Many consequentialists, in particular, take considerations concerning human nature to defeat certain demanding norms that would otherwise follow from their theory. One argument is that certain commitments ground psychological incapacitiesthat prevent us from doing what would maximize the good. Another is that we would be likely to suffer some kind of psychological demoralization if we tried to become significantly more selfless. I argue (...) that influential versions of both of these arguments underestimate our deliberative resources, and also fail to examine the kind of moral sources that may be able to sustain rigorous moral endeavour. Pessimism about our capacities for such endeavour results from the neglect of these factors, rather than from uncovering any significant limitations in human nature. (shrink)
