It's war time, and you're hiding in a basement with a group of other people. Enemy soldiers are approaching outside and will be drawn to any sound. If you're found, you'll all be killed immediately. A baby hiding with you starts to cry loudly and cannot be stopped. Smothering it to death is the only way to silence it, saving the lives of everyone in the room. Assume that the parents of the baby are unknown and not present and there will be no penalty for killing the child. Could you be the one who smothered it if no one else would?
You're in a lifeboat with several other people. The boat is overloaded and will capsize soon killing everyone aboard unless you lighten the load by one person. One of the passengers is grievously injured and is certain to die soon, but is fully alert and aware of everything that is going on. Could you throw that person overboard, knowing that that would save everyone else and that the person would know what you were doing while you were doing it?你和一堆人在一个救生船上.由于出题者的戏弄,这艘船超载了.如果不扔掉船上某个人的话,船翻掉之后大家就会一起仆街.出题者很善解人意的为你准备了一名重伤垂死的乘客---免掉了挑选的过程,但是他神智还算清醒,知道要发生些什么.在知道会救下整船人但是那个伤者注视着你的情况下,你会把他推到水里么?
An out of control trolley is heading down a track toward five unsuspecting people and will surely kill them all. You could throw a switch diverting it to a siding, but an equally unsuspecting man is standing there and the train will kill him instead. Could you throw the switch, killing one to save five?
In another version of the trolley dilemma, you and the man are on a bridge and you would have to push him onto the track to save the other five.
In a third version of the trolley dilemma, you could throw a switch catapulting him onto the track, thereby not having to touch him as you kill him. Could you do either of these other scenarios?
