 Mixed positions along the lines of those just discussed suppose that morality is objective in some respects, on account of some features of human nature, and relative in other respects. For the respects in which morality is relative, it is up to particular societies or individuals to determine which moral values to embrace. Hence, the authority of morality depends partly on objective factors and partly on the decisions of groups or individuals. Insofar as this is true, such mixed positions need to say something about the basis for these decisions and how conflicts are to be resolved (for example, when individuals dissent from groups or when people belong to different groups with conflicting values). The objective features of mixed positions may help resolve these issues, or may limit their import, but at the point where these features give out there remain some of the standard concerns about relativism (such as those raised in the last section).
