What the thing is
Moral relativism is not one idea. It is three separable positions: descriptive (observing cross-cultural moral disagreement), meta-ethical (treating moral claims as context-dependent truths), and normative (prescribing tolerance amid disagreement).
Where it came from
It has roots in ancient Greece and India. Westermarck formulated it systematically in Finland.
What it gets right
It correctly identifies that moral judgments vary across cultures. It distinguishes observation from prescription. It shows that descriptive disagreement does not force normative tolerance.
What it gets wrong
It wrongly implies meta-ethical relativism must follow from descriptive relativism—when the document confirms only that meta-ethical relativists are descriptive relativists, not that the latter logically entails the former.
Why it matters now
Because public discourse treats ‘moral disagreement’ as proof of either universal truth or total subjectivity. Moral relativism offers a scaffold to hold both facts and values without conflating them.
Is it worth your time
Yes—if you need to untangle moral disagreement without collapsing into dogma or indifference.
