The following is an excerpt from Professor Michael Sandel's latest lecture:
"See, all of modern morality can be reduced to the trolley problem. We've all heard the age-old problem: what if there is a trolley running along the tracks, and it will kill five people. However, you can pull a lever to change the tracks and have the trolley run over one person, but save the five. What is the morally correct thing to do?"
[At this point Sandel walked over to a window and began to stare through the slightly foggy glass at a developing rainstorm.]
