/there is a whole branch of moral philosophy dealing with such questions: Trolleyology
The initial Trolley problem:
The
trolley problem is a
thought experiment in
ethics. The general form of the problem is this:
There is a runaway
trolley barreling down the
railway tracks. Ahead, on the tracks, there are five people tied up and unable to move. The trolley is headed straight for them. You are standing some distance off in the train yard, next to a lever. If you pull this lever, the trolley will switch to a different set of tracks. However, you notice that there is one person on the side track. You have two options:
- Do nothing, and the trolley kills the five people on the main track.
- Pull the lever, diverting the trolley onto the side track where it will kill one person.
Which is the most ethical choice?
