Fireman dashes into burning house to rescue small child. But why? What is the impulse to risk all for the sake of another, the phenomenon Auguste Comte named "altruism"? The watching crowd may applaud such selfless bravery, but not so the man with a clipboard who has "Health and Safety" inscribed on the back of his orange fluorescent jacket. John 15:13 is no part of his creed - "Greater love has no one than this, that he lay down his life for his friends." In any strictly utilitarian or consequentialist philosophy, altruism makes no sense. If we don't step in and stop it, who knows who may sue?
