Barbara Fried argues that designing theories about this thought experiment dooms them to “marginal significance” in a review of the book On What Matters. A book titled for this thought experiment's “mysteries” collects the 2013 Berkeley Tanner lectures of Frances Kamm. A paper that compares this thought experiment to examples involving the (15[1])“Health-Pebble” and contrasts doing with merely (*) allowing was (10[1])written by Judith Jarvis (10[1])Thomson. This thought experiment was introduced in the paper Abortion and the Doctrine of Double Effect, by Philippa Foot. The central action of this thought experiment, which has a “fat man” (10[2])variant, is sometimes compared to harvesting organs to save transplant patients. For 10 points, name this thought experiment that asks if it (10[1])is moral to kill one person to save five from a certain vehicle. ■END■
