Abstract

In this paper I consider the challenge to rational choice posed by the problem of value incommensurability, and argue that incommensurabilists misrepresentour position as practical reasoners. In essence, I claim that reason has considerably more to work with than their arguments suggest, and that as a result it is possible for us to compare even the deepest values. To say that it is possible for us to compare values is not to say that it is always easy, however, or that thequestion of how best to characterize the common measure that allows for these comparisons isn’t open to vigorous dispute. But I argue that it is one thing to saythat the measure is obscure or that it guides us only imprecisely—and quite another to claim that it is conceptually impossible to weigh the deep values in lightof a common standard.
