I think I posted these before, but I think it's worth a re-visit.
You're standing on a bridge over a railway, there are five workmen fixing one of the tracks. You notice a runaway carriage heading towards them. None of them see or hear it, and they're too far away to hear your warnings. You realise that the only way to stop the carriage is to throw the switch and divert the carriage onto another track, but you know that doing this will kill one workman who's fixing that track. Would you throw the switch and kill one man instead of four?
What if there was no switch, and the only way to stop the carriage was to push something onto the tracks to block it's path. Unfortunately, the only thing at hand that could stop the carriage is a fat man standing next to you.
Would you push him onto the tracks, killing him, to spare the lives of the four men below? What if it was more than four men, what if it was another carriage full of people? Or a carriage full of school children, or a carriage full of pensioners? What if it was your family? Would that matter?
What if it wasn't a fat man on the bridge, what if it was a guy in a wheelchair, or a baby in a pushchair? Or your best friend? Would that matter?
What if you were a doctor working in a nearby hospital and the four workmen came in, having been hit by the runaway carriage, and they were all dying. One of them needed a heart transplant, one of them needed a kidney, and one of them needed a lung. In the next room you have a middle-aged man who's come in for a general check-up. Would you be willing to kill him and harvest his organs in order to save the lives of those four men?
What if you got into a car accident with four of your friends of family, and you all ended up in hospital. You escaped unscathed, but all the other passengers are in a bad way and need transplants - heart, lung, kidney etc. The hospital doesn't have any organs, but they say that if a patient were to die then they could use their organs. The guy in the next bed is in a coma and may never come out, would you reach over and switch off his life support to save your family or friends? What if it wasn't that easy, what if you had to smother the guy with a pillow?
What if you take it to a larger scale, what if you're a military general faced with the possibility of nuclear war. You know that you can stop the launch of nuclear missiles by carpet bombing a large area, but doing so would surely result in the deaths of innocent civilians. Is it ethical to do so in order to stop all-out war which would kill far more people? And if it's not, would you do it anyway?
Is it ethical to take one life to save another? Is it acceptable for one person to make these kind of decisions, based on what they thing is for the "greater good"? Which is worse, actively killing somebody by throwing a switch or pushing somebody over a bridge, or passively killing a greater number of people by refusing to do so?
