J.S. Mill understood morals in terms of duties. Contrary to his own intentions he did not provide a plausible explanation of what morals are because, having accepted Bentham's theoretical assumptions, he had to take over the thin concept of duty which is inseparable from them and which reduces duty to constraint and sanction. Since on this account legitimacy of a sanction depends on the decision of the individual or group who creates the sanction, morals must be understood in Mill's theory as imposed upon the society by those who have the power to enforce their rulings.
