 Murdoch left her position at Oxford in 1963 (though she continued to live in Oxford for some of each week) and increasingly lost touch with British academic philosophy. As of this writing, Murdoch is best known for a collection of three essays written in the 1960s, none originally published in easily accessible philosophy venues, published in 1970 as The Sovereignty of Good. This collection is by far the main source for professional philosophers writing on Murdoch, and of Murdoch’s broader impact on moral philosophy, and this entry will draw largely but not exclusively on that work.
