BBC NEWS | Magazine | What if...: Interesting article on philosophical quandaries. So I'll pose the questions to you guys:
1. One day, you wake up in hospital. In the nearby bed lies a world famous violinist who is connected to you with various tubes and machines. To your horror, you discover that you have been kidnapped by the Music Appreciation Society. Aware of the maestro's impending death, they hooked you up to the violinist. If you stay in the hospital bed, connected to the violinist, he will be totally cured in nine months. You are unlikely to suffer harm. No one else can save him. Do you have an obligation to stay connected?
2. A runaway trolley car is hurtling down a track. In its path are five people who will definitely be killed unless you, a bystander, flip a switch which will divert it on to another track, where it will kill one person. Should you flip the switch?
3. The runaway trolley car is hurtling down a track where it will kill five people. You are standing on a bridge above the track and, aware of the imminent disaster, you decide to jump on the track to block the trolley car. Although you will die, the five people will be saved.
Just before your leap, you realise that you are too light to stop the trolley. Next to you, a fat man is standing on the very edge of the bridge. He would certainly block the trolley, although he would undoubtedly die from the impact. A small nudge and he would fall right onto the track below. No one would ever know. Should you push him?
4. An enormous rock falls and blocks the exit of a cave you and five other tourists have been exploring. Fortunately, you spot a hole elsewhere and decide to let "Big Jack" out first. But Big Jack, a man of generous proportions, gets stuck in the hole. He cannot be moved and there is no other way out. The high tide is rising and, unless you get out soon, everyone but Big Jack (whose head is sticking out of the cave) will inevitably drown. Searching through your backpack, you find a stick of dynamite. It will not move the rock, but will certainly blast Big Jack out of the hole. Big Jack, anticipating your thoughts, pleads for his life. He does not want to die, but neither do you and your four companions. Should you blast Big Jack out? If the roles were reversed, what would you advise your trapped companions to do?
Read these first and type out your answers as a comment. Then read the discussions below and add to your comment (appending, not changing what is already there) if necessary.
1. This experiment is used to show that a pregnant woman need not go to full term with her baby, as long as she had taken reasonable steps to avoid getting pregnant. It is thus a "pro-choice" argument.
The violinist represents the baby, and you - in the hospital bed - play the role of the mother. If you think unhooking yourself from the violinist is acceptable, but aborting an unwanted foetus is not, what are the moral differences between the two cases? In both situations, you could save a person by bearing a great burden for nine months.
2 & 3: Philippa Foot would say that everyone ("without hesitation") would choose to flip the switch in the first trolley case, but that most of us would be appalled at the idea of pushing the fat man. The philosophical puzzle is this: Why is it acceptable to sacrifice the one person in The Runaway Trolley Car but not in The Fat Man case? Can it ever be morally acceptable to kill an innocent person if that is the only way to save many? Should some actions - such as deliberately killing innocent people against their wishes - never be done?
