Mary Midgley, the lesser-known friend of Elizabeth Anscombe, Philippa Foot, and Iris Murdoch, was a deliberately multidisciplinary thinker. She was convinced that moral philosophers must relate various bodies of knowledge to one another if they are to achieve an adequate understanding of human life, human motivation, and human success or failure. Midgley, writing from the margins of the discipline, was the first to present a positive proposal for the kind of moral philosophy recommended but never developed by Anscombe, Foot, and Murdoch: a naturalistic moral philosophy, grounded in the character and needs of the human animal.
