 Another approach might be construed as a mixed position, though it was not put forward in these terms. Isaiah Berlin (1998) argued that, though some moral values are universal, there are also many objective values that conflict and are not commensurable with one another. He called his position pluralism and rejected the label ‘relativism’ (see the entry on  Isaiah Berlin).  But if incommensurability implies that these conflicts cannot be rationally resolved, then it might suggest a concession to relativism.
