In the middle of the 20th century, four women at the University of Oxford began careers that would revolutionize the fields of ethics and analytic philosophy. Elizabeth Anscombe, Wittgenstein’s student and translator, integrated ordinary language philosophy with Aristotelian practical reasoning. Philippa Foot defended the objectivity of morality, invented the Trolley problem, and articulated a modern account of ethical naturalism. Mary Midgley challenged reductionism and sociobiology while developing a fulsome account of our relationship to non-human animals. Iris Murdoch, through story as much as treatise, brought analytic philosophy into conversation with Continental philosophy, Eastern philosophy, and Platonic moral realism. This seminar examines the philosophy and legacy of these four women, friends, pioneers, and philosophers.
