An Introduction to the Philosophy of Law is a written version of lectures delivered before the Law School of Yale University as Storrs Lectures in the school year 1921-1922. A metaphysician who had written on the secret of Hegel was congratulated upon his success in keeping the secret. One who essays an introduction to the philosophy of law may easily achieve a like success. His hearers are t unlikely to find that he has presented t one subject but two, presupposing a kwledge of one and giving them but scant acquaintance with the other. If he is a philosopher, he is t unlikely to have tried a highly organized philosophical apparatus upon those fragments of law that lie upon the surface of the legal order, or upon the law as seen through the spectacles of some jurist who had interpreted it in terms of a wholly different philosophical system. Looking at the[Pg 10] list of authorities relied upon in Spencer's Justice, and ting that his historical legal data were taken from Maine's Ancient Law and thus came shaped by the political-idealistic interpretation of the English historical school, it is t difficult to perceive why positivist and Hegelian came to the same juristic results by radically different methods. On the other hand, if he is a lawyer, he will very likely have been able to do more than attempt ne too intelligently to work with the complicated and delicate engines of others upon the toughest and most resistant of legal materials. Until some Anglo-American jurist arises with the universal equipment of Josef Kohler the results of common-law incursions into philosophy will resemble the effort of the editorial writer who wrote upon Chinese Metaphysics after reading in the Encyclopaedia Britannica under China and Metaphysics and combining his information. Yet such incursions there must be. Philosophy has been a powerful instrument in the legal armory and the times are ripe for restoring it to its old place therein. At least one may show what philosophy has done for some of the chief problems of the science of law, what stands before us to be done in some of the more conspicuous problems of that science today in which philosophy may help us, and how it is possible to look at those problems philosophically without treating them in terms of the eighteenth-century natural law or the nineteenth-century metaphysical jurisprudence which stand for philosophy in the general understanding of lawyers. Nathan Roscoe Pound was a distinguished American legal scholar and educator. In 1903, Pound became dean of the University of Nebraska College of Law. In 1910, Pound began teaching at Harvard and in 1916 became dean of Harvard Law School. He wrote Spurious Interpretation in 1907, Outlines of Lectures on Jurisprudence in 1914, The Spirit of the Common Law in 1921, Law and Morals in 1924, and Criminal Justice in America in 1930.
