Bentham's book An Introduction to the Principles of Morals and Legislation was printed in 1780 but not published until 1789. It is possible that Bentham was spurred on to publish after he saw the success of Paley's Principles of Moral and Political Philosophy.[22] Though Bentham's book was not an immediate success, [23] his ideas were spread further when Pierre Étienne Louis Dumont translated edited selections from a variety of Bentham's manuscripts into French. Traité de legislation civile et pénale was published in 1802 and then later retranslated back into English by Hildreth as The Theory of Legislation, although by this time significant portions of Dumont's work had already been retranslated and incorporated into Sir John Bowring's edition of Bentham's works, which was issued in parts between 1838 and 1843.Perhaps aware that Francis Hutcheson eventually removed his algorithms for calculating the greatest happiness because they "appear'd useless, and were disagreeable to some readers,"[24] Bentham contends that there is nothing novel or unwarranted about his method, for "in all this there is nothing but what the practice of mankind, wheresoever they have a clear view of their own interest, is perfectly conformable to."Rosen (2003) warns that descriptions of utilitarianism can bear "little resemblance historically to utilitarians like Bentham and J. S. Mill" and can be more "a crude version of act utilitarianism conceived in the twentieth century as a straw man to be attacked and rejected."[25] It is a mistake to think that Bentham is not concerned with rules. His seminal work is concerned with the principles of legislation and the hedonic calculus is introduced with the words "Pleasures then, and the avoidance of pains, are the ends that the legislator has in view." In Chapter VII, Bentham says: "The business of government is to promote the happiness of the society, by punishing and rewarding.... In proportion as an act tends to disturb that happiness, in proportion as the tendency of it is pernicious, will be the demand it creates for punishment."Principle of utilityBentham's work opens with a statement of the principle of utility: [26]Nature has placed mankind under the governance of two sovereign masters, pain and pleasure. It is for them alone to point out what we ought to do.... By the principle of utility is meant that principle which approves or disapproves of every action whatsoever according to the tendency it appears to have to augment or diminish the happiness of the party whose interest is in question: or, what is the same thing in other words to promote or to oppose that happiness. I say of every action whatsoever, and therefore not only of every action of a private individual, but of every measure of government.
