Judith Jarvis Thomson 1929 – 2020

Judith Jarvis Thomson was an American moral and metaphysical philosopher and a long-serving professor at the Massachusetts Institute of Technology. Her A Defense of Abortion, published in 1971, became one of the most discussed papers in twentieth-century moral philosophy and inaugurated a new style of careful, scenario-driven argument in applied ethics. She also developed the trolley problem in its modern form, making it the central test case for theories of permissible harm. Her Realm of Rights articulated a comprehensive theory of moral rights, while late work returned to questions of action and metaphysics.
