Begging the Question: A Qualified Defense

This discussion examines two of the central notions at work in Sterba’s From Rationality to Equality: question-beggingness, and the notion of a rational requirement. I point out that, against certain unreasonable positions, begging the question is a perfectly reasonable option. I also argue that if we use the sense of “rational requirement” that philosophers ought (and tend) to have in mind when defending the idea that morality is rationally required, then Sterba has not succeed in defending this idea. Rather, he has at most demonstrated the rational preferability of morality over two other positions: an extreme egoism, and a very particular form of altruism. But another position exists: one that holds altruistic reasons to exist, and to be capable of justifying sacrifices, but that also holds that they do not require us to sacrifice our interests in the way that morality sometimes does require.
