  The psychological egoist can concede that I must have desires for particular things, such as playing hockey. But there is no need to concede that the satisfaction of these desires is not part of my welfare. My welfare might consist simply in the satisfaction of self-regarding desires. In the case of deriving welfare from helping others, the psychological egoist can again concede that I would not derive welfare without desiring some particular thing, but need not agree that what I desire for its own sake is that others do well. That I am the one who helps them may, for example, satisfy my self-regarding desire for power.
