Abstract

Sidgwick believes that his own proto-utilitarian axioms satisfy criteria for self-evidence, while the principles of common sense morality, including the principle requiring fidelity to promises, do not. I articulate Sidgwick's argument for this claim, in Book III of the Methods, but suggest that it fails: its official version is vulnerable to a charge of unfairness, and its unofficial version cannot establish Sidgwick's view against Ross's.
