In extreme forms, subjectivist and relativist positions can be applied to conclude that what is true for others may not be true for me, rendering it impossible to evaluate the moral weight of even radically different actions. Critics of relativistic positions point to the failure of relativism to provide a workable means for resolving ethical issues since every action can be judged differently, depending on the actor's point of view.
