" This sort of underlying logic—closet utilitarianism—often emerges when the logic behind basic “rights” is teased out. “The greatest-happiness principle,” Mill wrote, “has had a large share in forming the moral doctrines even of those who most scornfully reject its authority. Nor is there any school of thought which refuses to admit that the influence of actions on happiness is a most material and even predominant consideration in many of the details of morals, however unwilling to acknowledge it as the fundamental principle of morality, and the source of moral obligation.
