Professor Gendler begins with brief introductory remarks about the course’s methodology, explaining the approach that was taken to reading and presenting various articles. She continues with a discussion of Cass Sunstein’s work on social norms, looking particularly at his account of the willingness to pay/willingness to accept distinction. The lecture continues with a consideration of how this distinction-–and the heuristic reasoning that gives rise to it–-might be used to explain our responses to the trolley problem. In the final segment of the lecture, Professor Gendler offers a way of thinking systematically about relations among the political philosophical views of Thomas Hobbes, John Rawls and Robert Nozick.
