Philippa Foot

British philosopher at Oxford — who created the Trolley Problem as a philosophical thought experiment — revived virtue ethics against utilitarianism and Kantian deontology — and created the theory of natural goodness in Natural Goodness.

Creates the Trolley Problem — Foot's 1967 thought experiment (would you pull a lever to divert a trolley from killing five to killing one?) has become the most discussed thought experiment in philosophy and psychology and forms the empirical basis for research on moral intuition.
