Argument From Relativity Quotes

“The argument from relativity has as its premiss the well-known variation in moral codes from one society to another and from one period to another, and also the differences in moral beliefs between different groups and classes within a complex community. Such variation is in itself merely a truth of descriptive morality, a fact of anthropology which entails neither first order nor second order ethical views. Yet is may indirectly support second order subjectivism: radical differences between first order moral judgments make it difficult to treat those judgments as apprehensions of objective truths.”
