Harvard University: Michael Sandel's "The Case for Cannibalism"
Watch the rest of this lecture, starting at 24:13. This lecture introduces Jeremy Bentham's utilitarian moral principle. Through the case of the shipwrecked crew, Sandel demonstrates that, far from abstract puzzles, moral dilemmas are real life problems, which demand that we strive toward coherent moral codes that can be agreed upon for social and legal purposes.
