 Once again, the egoist might reply that it is an a priori truth that all of our actions are ultimately motivated only by self-interest, but we have seen the weakness of the premises that support that argument. So, if the hypothesis that sometimes one acts only for one’s own sake is true, it must recommend itself to us because close observation of human behavior supports it. We must find actual cases of someone promoting his own good only for his own sake. It is no easier to be confident about such matters than it is easy to be confident that someone has acted out of purely altruistic motives. We realize that much of what we do for ourselves has consequences for other people as well, and we care to some degree about those other people. Perhaps our ultimate motivation always includes an other-regarding component. It is more difficult to find evidence against that suggestion than one might have thought.
