The Humean legacy in moral philosophy has given rise to the following familiar divergence of views:
1. Moral questions are questions of feeling. Rational discussion can occur given the acceptance of unreasoned commitments to values or principles, but it must not be thought that these values or principles can themselves be justified rationally. Moral disagreements may be resolved through persuasion, but it is appropriate for rational persons to be permanently irreconcilable in their moral views.
2. Moral questions are questions of fact and/or logic. They are therefore in principle resolvable through rational discussion, like any other questions of fact and/or logic. The idea that rational persons should be permanently unable to agree on moral questions, despite indefinitely lengthy discussion and enquiry, is unintelligible.
