Abstract
As an initial approximation, pluralism may be understood as the combination of four theses. First, there are many incommensurable values whose realization is required for living a good life. Second, these values often conflict with each other, and, as a result, the realization of some excludes the realization of others. Third, there is no authoritative standard that could be appealed to to resolve such conflicts, because there is also a plurality of standards; consequently, no single standard would be always acceptable to all fully informed and reasonable people. Fourth, there are, nevertheless, reasonable ways of resolving conflicts among incommensurable values
