Abstract

In the moral philosophy of the last two centuries, altruism of one kind or another has typically been regarded as identical with moral concern. When self-regarding duties have been recognized, motivation by duty has been sharply distinguished from motivation by self-interest . Accordingly, from Kant, Mill, and Sidgwick to Rawls, Nagel, and Gauthier, concern for our own interests, whether long-term or short-term, has typically been regarded as intrinsically nonmoral. So, for example, although Thomas Nagel regards both prudence and altruism as structural features of practical reason, he identifies only the latter as a moral capacity, prudence being merely rational, long-term egoism. Similarly, John Ravvls and David Gauthier contrast self-interest and other nontuistic interests—interests that are independent of others' interests—with moral interest. We are morally permitted , no doubt, to act out of self-interest within certain constraints, but such acts can have no intrinsic moral worth. Pursuit of our own interests out of duty does have intrinsic moral worth, but such pursuit, by hypothesis, cannot be motivated by self-interest. Self-interested pursuit of our own interests as such, no matter how realistic, farsighted, temperate, honest, or courageous, cannot be intrinsically moral. And this remains the case even if self-interest motivates us to perform other-regarding acts: only those other-regarding acts that are motivated by others' interests count as moral, because only such acts are altruistic
