to be learned by students rather than debated by colleagues." Nevertheless, his book The Principles of Moral and Political Philosophy (1785) was a required text at Cambridge and Smith (1954) says that Paley's writings were "once as well known in American colleges as were the readers and spellers of William McGuffey and Noah Webster in the elementary schools." Schneewind (1977) writes that "utilitarianism first became widely known in England through the work of William Paley." The now forgotten significance of Paley can be judged from the title of Thomas Rawson Birks's 1874 work Modern Utilitarianism or the Systems of Paley, Bentham and Mill Examined and Compared. Apart from restating that happiness as an end is grounded in the nature of God, Paley also discusses the place of rules, writing: Classical utilitarianism Jeremy Bentham 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. Though Bentham's book was not an immediate success, his ideas were spread further when Pierre Étienne Louis Dumont translated edited selections from a variety of Bentham's manuscripts into French. Traité de législation 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," 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." 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
