Appendix IV. — The Divisions of the Law
English law possesses no received and authentic scheme of orderly arrangement. Exponents of this system have commonly shown themselves too little careful of appropriate division and classification, and too tolerant of chaos. Yet we must guard ourselves against the opposite extreme, for theoretical jurists have sometimes fallen into the contrary error of attaching undue importance to the element of form. They have esteemed too highly both the possibility and the utility of ordering the world of law in accordance with the straitest principles of logical development. It has been said by a philosopher concerning human institutions in general, and therefore concerning the law and its arrangement, that they exist for the uses of mankind, and not in order that the angels in heaven may delight themselves with the view of their perfections. In the classification of legal principles the requirements of practical convenience must prevail over those of abstract theory. The claims of logic must give way in great measure to those of established nomenclature and familiar usage; and the accidents of historical development must often be suffered to withstand the rules of scientific order. Among the various points of view of which most branches of the law admit, there are few, if any, which may be wisely adopted throughout their whole extent, and among the various alternative principles of classification, expedience allows of no rigidly exclusive and consistent choice. There are few distinctions, however important in their leading applications, which may not rightly, as they fade towards the boundary line, be replaced by others which there possess a deeper significance. We may rest content, therefore, if, within the limits imposed by the needful conformity to received speech and usage, each portion of the law is dealt with in such of its aspects as best reveals its most important characters and relations, and in such order as is most consistent with lucid and concise exposition.
