Abstract

Suppose that virtue is intrinsically morally good, and that we have a pro tanto moral reason to act in ways which promote it. Further suppose that the failure of agents to receive what they deserve is intrinsically morally bad, and that we have a pro tanto moral reason not to act in ways which frustrate desert. When we are deciding whether to encourage others to make altruistic sacrifices, these two pro tanto moral reasons come into conflict. To encourage such sacrifices promotes virtue; it also causes virtuous agents to be worse off, preventing them from receiving their deserts. I argue that these effects on desert can reduce the moral desirability of promoting altruism so significantly as to make it morally wrong. This has implications for public policy, since certain practical questions turn on the extent to which we ought to rely on altruism as a means of solving social problems.
