But what if in order to save 0nc’s life one has to ki]1 another person? In some cases that is obviously permissible. In a case I will call Villainous Aggrcssor, you are standing in :1 meadow, innocently minding your own business, and 21 truck suddenly heads toward you. You try to sidestep the truck, but it tums as you tum. Now you can sec the driver: he is a mam you know has long hated you. What to do? You cannot (...) outrun thc truck. Fortunately, this is not pure nightmare: you just happen to have em antitank gun with you, and can blow up the truck. Of course, if you do this you will kill thc driver, but that does not matter; it is morally permissible for you to blow up thc truck, driver and 211, in defense of your life. (shrink)

How should deontologists concerned with the ethics of killing apply their moral theory when we don’t know all the facts relevant to the permissibility of our action? Though the stakes couldn’t be higher, and uncertainty is endemic where killing is concerned, few deontologists have an answer to this question. In this paper I canvass two possibilities: that we should apply a threshold standard, equivalent to the ‘beyond a reasonable doubt’ standard applied for criminal punishment; and that we should fit our (...) deontological ethical theory into the apparatus of decision theory. I show that the first approach faces insurmountable obstacles, while the second holds much more promise for deontologists than they might first have assumed. (shrink)
