Questions of Ethics

[Nat]

I asked this on my facebook page after hearing it on a Philosphy Bites podcast, and the question took off pretty well. So I'll ask it here:

A train is coming down the tracks and will hit 5 people and kill them - unless a bystander - who is standing next to a switch that would move the train to another track - decides to flip this switch. If s/he does this, only one person would be killed. Should the bystander flip the switch?

I think you need to probably imagine that none of these folks are people you know. They are all of the same value to you - all strangers, all the same age, all law-abiding, all in the same state of health, etc. in order to do real justice to this question. You would also need to imagine that the bystander knows that if he throws the switch, the train will behave in the way it's supposed to.

BUT, it would be interesting also to hear what variables would influence you regarding whether the bystander should throw the switch.
