generalize them into a thoroughly connected system. The process is one, from a lawyer's statement of a case, eliminating as it does all the dramatic elements with which his client's story has clothed it, and retaining only the facts of legal import, up to the final analyses and abstract universals of theoretic jurisprudence. The reason why a lawyer does not mention that his client wore a white hat when he made a contract, while Mrs. Quickly would be sure to dwell upon it along with the parcel gilt goblet and the sea-coal fire, is that he forsees that the public force will act in the same way whatever his client had upon his head. It is to make the prophecies easier to be remembered and to be understood that the teachings of the decisions of the past are put into general propositions and gathered into text-books, or that statutes are passed in a general form. The primary rights and duties with which jurisprudence busies itself again are nothing but prophecies. One of the many evil effects of the confusion between legal and moral ideas, about which I shall have something to say in a moment, is that theory is apt to get the cart before the horse, and to consider the right or the duty as something existing apart from and independent of the consequences of its breach, to which certain sanctions are added afterward. But, as I shall try to show, a legal duty so called is nothing but a prediction that if a man does or omits certain things he will be made to suffer in this or that way by judgment of the court;—and so of a legal right.
The number of our predictions when generalized and reduced to a system is not unmanageably large. They present themselves as a finite body of dogma which may be mastered within a reasonable time. It is a great mistake to be frightened by the ever increasing number of reports. The reports of a given jurisdiction in the course of a generation take up pretty much the whole body of the law, and restate it from the present point of view. We could reconstruct the corpus from them if all that went before were burned. The use of the earlier reports is mainly historical, a use about which I shall have something to say before I have finished.
I wish, if I can, to lay down some first principles for the study of this body of dogma or systematized prediction which we call the law, for men who want to use it as the instrument of their business to enable them to prophesy in their turn, and, as bearing upon the study, I wish to point out an ideal which as yet our law has not attained.
