Ethical Particularism and Morally Relevant Properties

This paper follows a path that takes us from utilitarianism to particularism. Utilitarianism is the leading one-principle theory; its falsehood is here simply asserted. W. D. Ross’s theory of prima facie duty is offered as the strongest many-principle theory. Ross’s two accounts of his notion of a prima facie duty are considered and criticized. But the real criticism of his view is that being a prima facie duty is a context-sensitive notion, since a feature that is a prima facie duty-making feature in one case may be prevented from playing that role in another. Since the strongest many-principle theory is therefore false, the only conclusion is a no-principle theory: a theory that allows moral reasons but does not suppose that they behave in the regular way required for there to be moral principles—namely, moral particularism.
