INTENTIONS AND TROLLEYS

The series of 'trolley' examples issue a challenge to moral principles based on intentions, since it seems that these give the wrong answers in two important cases: 'Fat Man', where they seem to say that it is permissible to push someone in front of a trolley to save others, and 'Loop', where they seem to say that it is wrong to divert a trolley towards a single person whose body will stop it and save others. I reply, first, that there is a parallel between the wrongful intention to mutilate in 'Transplant', where one person's vital organs are removed to save others' lives, and the intention to assault in Fat Man. Secondly, I defend Frances Kamm's view that in Loop one can divert the trolley towards the one without an intention to kill or assault, since good potential side-effects can be taken into account in deciding what to do, without their becoming intentions.
