Philippa Foot’s career at Oxford spanned much of the sprawling twentieth-century. Foot came to be a champion of neo-Aristotelian virtue ethics, in contrast to the schools of deontology and utilitarian consequentialism that held sway in much of the Anglo-American philosophical world. Her Natural Goodness (Oxford: Clarendon Press, 2001) was her last contribution to the discussion.
Here is my interview with Professor Douglas Rasmussen on Foot’s work in ethical theory.
And here is Wikipedia’s entry on Foot.
Ave atque vale, Professor Foot.
Update: A remembrance from a former student of Foot’s.
