relativism
view that beliefs and values reflect the particular times and places in which they are held. Instead of their lasting for all time and applying universally, they are subject to social and cultural conditioning. This was the conclusion of
some philosophers, both Greek and Indian, going back over two thousand years: change and diversity are omnipresent. It has been reinforced by the observations of cultural anthropologists and globe trotting tourists. However, other philosophers and social scientists draw attenion instead to constants and continuities.
