“If you do something to benefit one person, that is an absolute gain, and its relative insignificance in the wider scheme is irrelevant. Benefit two people without concomitant harm to others - or a village, tribe, city, class, nation, society or civilisation - and the benefits are scalable, arithmetic. There is no excuse beyond fatalistic self-indulgence and sheer laziness for doing nothing.”
