I know that it would be morally better to help than to continue relaxing. But how bad, exactly, would it be for me not to help? Pretty bad? Only a little bad? Not at all bad, but also not as good as I would like to be if I weren’t feeling so lazy? These are the questions that occupy my mind. In most cases, we already know what is good. No special effort or skill is required to figure that out. Much more interesting and practical is the question of how far short of the ideal we are comfortable being.
