Note (return) — Chapter XIII

Social morality is, like private morality, founded upon utility. As nothing is intrinsically right or wrong in private life, so nothing is intrinsically just or unjust in social life. "Justice has no independent existence: it results from mutual contracts, and establishes itself wherever there is a mutual engagement to guard against doing or sustaining any injury. Injustice is not intrinsically bad; it has this character only because there is joined with it the fear of not escaping those who are appointed to punish actions marked with this character." 779 Society is thus a contract--an agreement to promote each other's happiness. And inasmuch as the happiness of the individual depends in a great degree upon the general happiness, the essence of his ethical system, in its political aspects, is contained in inculcating "the greatest happiness of the greatest number."
