"When you are thinking about whether you have an obligation to try to save people's lives, you don't usually think, well, how close by are they? Understanding what we are reacting to can change the way we think about the problem. If, biologically, morality evolved to help us get along with individuals in our community, it makes sense that we have heartstrings that can be tugged - and that they are not going to be tugged very hard from far away. But does that make sense? From a more reflective moral perspective, that may just be a cognitive glitch."
