Moral absolutism holds that good and evil are fixed concepts established by a deity or deities, nature, morality, common sense, or some other source. Amoralism claims that good and evil are meaningless, that there is no moral ingredient in nature. Good and bad are often thought of as synonymous with right and wrong, particularly in the moral definition. 'Right' in this sense is not logical correctness but conformance to rules, which in the good-bad sense are the social norms of morality.
