ABSTRACT
There is a long-standing dispute among philosophers concerning the relationship between rationality and morality. Philosophers disagree about whether rationality supports morality in any significant way. Some philosophers hold that rationality requires all rational persons to put forward morality as a guide to behavior that governs all of them. Others go even further and claim that rationality requires everyone to act morally. James P.Sterba in his book, Justice for Here and Now, is one of the latter philosophers. Others, like myself, claim that rationality clearly does not require acting morally, and that it requires all rational persons to put forward morality as a guide to behavior that governs all of them, only with some significant qualifications. The disagreement between Sterba and myself involves both our accounts of rationality and our accounts of morality, but it also involves something else. We disagree about whether what needs to be shown is if it is practical rationality or theoretical rationality that requires acting morally.
