  Why believe even the relatively modest motivational form of psychological hedonism? One argument infers it from the motivational egoist claim that each of us is always motivated to maximize what we take to be our own good, plus the claim that we each accept that our good is our maximal or sufficient balance of pleasure over displeasure. But motivational egoism is at best controversial (see entry on  egoism).  Also controversial is the psychological thesis that each of us accepts hedonism about our own good. For one thing, it ungenerously implies that those who think they reject hedonism about their own good do not even know their own minds on this matter.
