working to the exclusive benefit of individuals and the prejudice of the common weal, it has good ground for the suppression of those forms of property, while it may, with equal justice, maintain other forms of property which it holds sound as judged by the effect on the common welfare. It is limited by no "imprescriptible" right of the individual. It may do with the individual what it pleases provided that it has the good of the whole in view. So far as the question of right is concerned the Benthamite principle might be regarded as decidedly socialistic or even authoritarian. It contemplates, at least as a possibility, the complete subordination of individual to social claims. There is, however, another side to the Benthamite principle, to understand which we must state the heads of the theory itself as a positive doctrine. What is this social utility of which we have spoken? In what does it consist? What is useful to society, and what harmful? The answer has the merit of great clearness and simplicity. An action is good which tends to promote the greatest possible happiness of the greatest possible number of those affected by it. As with an action, so, of course, with an institution or a social system. That is useful which conforms to this principle. That is harmful which conflicts with it. That is right which conforms to it, that is wrong which conflicts with it. The greatest happiness principle is the one and supreme principle of conduct. Observe that it imposes on us two considerations. One is the _greatest_ happiness. Now happiness is defined as consisting positively in the presence of pleasure, negatively in the absence of pain. A greater pleasure is then preferable to a lesser, a pleasure unaccompanied by pain to one involving pain. Conceiving pain as a minus quantity of pleasure, we may say that the principle requires us always to take quantity and pleasure into account, and nothing else. But, secondly, the _number_ of individuals affected is material. An act might cause pleasure to one and pain to two. Then it is wrong, unless, indeed, the pleasure were very great and the pain in each case small. We must balance the consequences, taking all individuals affected into account, and "everybody must count for one and nobody for more than one." This comment is an integral part of the original formula. As between the happiness of his father, his child, or himself, and the happiness of a stranger, a man must be impartial. He must only consider the quantity of pleasure secured or pain inflicted.
