Each person or culture develops their own moral values. There is a strong emphasis on the fact that we are shaped by our culture, and a consequent diminishing of personal responsibility. Tolerance Tolerance of other views is one of the pillars of postmodernism. This intolerance is especially directed to those who think others might be wrong. There is a strong emphasis on individualism.
History There is much rewriting of history.
What really happened is either unknowable or unimportant. There is no truth, only truths. There are no principles, only preferences. There is no grand reason, only reasons. There is no privileged civilization, only a multiple of cultures, beliefs, periods, and styles.
