 With respect to truth-value, this means that a moral judgment such as ‘Polygamy is morally wrong’ may be true relative to one society, but false relative to another. It is not true, or false, simply speaking. Likewise, with respect to justification, this judgment may be justified in one society, but not another. Taken in one way, this last point is uncontroversial: The people in one society may have different evidence available to them than the people in the other society. But proponents of MMR usually have something stronger and more provocative in mind: That the standards of justification in the two societies may differ from one another and that there is no rational basis for resolving these differences. This is why the justification of moral judgments is relative rather than absolute.
