In From Rationality to Equality, James Sterba argues that the non-moral, and non-controversial, principle of logic, the principle that good arguments do not beg-the-question, provides a rationally conclusive response to egoism. He calls this “the principle of non-question-beggingness” and it is supposed to justify a conception of “Morality as Compromise.” Sterba’s basic idea is that principles of morality provide a non-question-begging compromise between self-interested reasons and other-regarding reasons. I will focus, first, on Sterba’s rejection of the alternative Kantian rationalist justification (...) of morality, and second, I discuss the logical principle of non-question-beggingness and I argue that Sterba is wrong to assume that there is a formal, logical requirement that a rational egoist must provide a non-question-begging defense of egoism. I argue that, like the Kantian, Sterba needs a more substantial conception of practical reason to derive his conclusion. My third focus is the problem of reasonable pluralism and public reason . The Rawlsian principle of public reason is analogous to Sterba’s principle of non-question-beggingness. Sterba recognizes that public policies should respect competing perspectives and that a public conception of justice must be justifiable to all reasonable people. The problem is that that reasonable people disagree about fundamental moral questions. Rawls calls this the fact of reasonable pluralism. I argue that an intercultural conception of justice is necessary to provide a response to reasonable pluralism and a shared basis for public reason. (shrink)
