[catalogued under 22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / b. Rational ethics]

Full Idea

The ultimate warrant for moral principles cannot be found in reason. The sort of opprobrium that attaches to moral transgressions is quite unlike the sort of opprobrium that attaches to the requirements of reason.

Gist of Idea

Morality isn't based on reason; moral indignation is quite unlike disapproval of irrationality

A Reaction
