This problem affects a question close to Frances Kamm’s work: what she calls the Problem of Distance in Morality (PDM). Kamm says that her intuition consistently finds that moral obligations attach to things that are close to us, but not to thinks that are far away. According to her, if we see a child drowning in a pond and there’s a machine nearby which, for a dollar, will scoop him out, we’re morally obligated to give the machine a dollar. But if the machine is here but the scoop and child are on the other side of the globe, we don’t have to put a dollar in the machine. --Aaron Swartz
