That great science which regards nature and the operations of the human mind, is popularly divided into Morals and Metaphysics. The latter relates to a just classification, and the assignment of distinct names to its ideas; the former regards simply the determination of that arrangement of them which produces the greatest and most solid happiness. It is admitted that a virtuous or moral action, is that action which, when considered in all its accessories and consequences, is fitted to produce the highest pleasure to the greatest number of sensitive beings. The laws according to which all pleasure, since it cannot be equally felt by all sensitive beings, ought to be distributed by a voluntary agent, are reserved for a separate chapter.
