Scottish-born British philosopher and a leading voice of early 20th-century ethical intuitionism. He was also a top Aristotle scholar who led the editing of the Oxford translation of Aristotle's works.

In The Right and the Good (1930) he criticized both utilitarianism and Kantianism and proposed a pluralist deontology: we have several irreducible "prima facie duties." He was knighted in 1938.

Big ideas

Prima facie dutiesKeeping promises, honesty, gratitude, justice, beneficence, not harming — each carries its own independent weight.
Conflicts and judgmentWhen duties clash, which one wins isn't settled by a formula but by judgment about the specific situation.
Self-evident moral truthsA mature person knows prima facie duties to be true intuitively, like mathematical axioms.

If you think like them…

If you're like Ross, you feel no single principle can explain all of morality. Promises matter, outcomes matter, and you know how to weigh them differently case by case. You also believe right and wrong are something we recognize, not something people agree to make up.
