  A third argument, like Moore’s, claims that ethical egoism is inconsistent in various ways. Say ethical egoism recommends that A and B both go to a certain hockey game, since going to the game is in the self-interest of each.  Unfortunately, only one seat remains. Ethical egoism, then, recommends an impossible state of affairs. Or say that I am A and an ethical egoist. I both claim that B ought to go to the game, since that is in her self-interest, and I do not want B to go to the game, since B’s going to the game is against my self-interest.
