John Ruskin once said that a proper estimation of the accomplishments of a period in human history can only be obtained by careful study of three books--The Book of the Deeds, The Book of the Arts, and the Book of the Words, of the given epoch. The Thirteenth Century may be promptly ready for this judgment of what it accomplished for men, of {7} what it wrote for subsequent generations, and of the artistic qualities to be found in its art remains. In the Book of the Deeds of the century what is especially important is what was accomplished for men, that is, what the period did for the education of the people, not alone the classes but the masses, and what a precious heritage of liberty and of social coordination it left behind. To most people it will appear at once that if the most important chapter of Thirteenth Century accomplishment is to be found in the Book of its Deeds and the deeds are to be judged according to the standard just given of education and liberty, then there will be no need to seek further, since these are words for which it is supposed that there is no actual equivalent in human life and history for at least several centuries after the close of the Thirteenth. As a matter of fact, however, it is in this very chapter that the Thirteenth Century will be found strongest in its claim to true greatness. The Thirteenth Century saw the foundation of the universities and their gradual development into the institutions of learning which we have at the present time. Those scholars of the Thirteenth Century recognized that, for its own development and for practical purposes, the human intellect can best be trained along certain lines. For its preliminary training, it seemed to them to need what has since come to be called the liberal arts, that is, a knowledge of certain languages and of logic, as well as a thorough consideration of the great problems of the relation of man to his Creator, to his fellow-men, and to the universe around him. Grammar, a much wider subject than we now include under the term, and philosophy constituted the undergraduate studies of the universities of the Thirteenth Century. For the practical purposes of life, a division of post-graduate study had to be made so as to suit the life design of each individual, and accordingly the faculties of theology, for the training of divines; of medicine, for the training of physicians; and of law, for the training of advocates, came into existence.
