Moral philosophers who differ from one another on a wide range of questions tend to agree on at least one general point. Most believe that things are worth valuing either because of their relationship to something else worth valuing, or because they are simply (in themselves) worth valuing. I value my car, because I value getting to work; I value getting to work, because I value making money and spending time productively; and I value those things because I value leading (...) a fulfilling life—and that valuing needs no justification. The values that need to be justified by other values are extrinsic; those that do not are intrinsic. Most traditional philosophical approaches to value justification are foundational in this sense: intrinsic values provide a foundation upon which other values can be justified. (shrink)

Moral nihilism maintains that value judgments cannot be justified. In this paper I argue against two prominent nihilistic theories: error theory and expressivism. First I present a meta-valuation thesis, which holds that it would be more valuable if at least some value judgments were justified. Second I argue for a value-justification thesis, which holds that the greater value of value-justifying theories warrants a rejection of nihilistic theories. This latter thesis requires a pragmatist premise: justified beliefs are the most valuable of (...) possible beliefs. With this premise and a critique of meta-ethical theory choice, I argue that meta-ethical justification proceeds via an atypical form of the method of reflective equilibrium. Since this particular method cannot produce a justification for error theory or expressivism, I conclude that these two forms of moral nihilism should be rejected in favor of more valuable meta-ethical theories.
