For this great Pope, however, there was no greater teacher of any of the serious philosophical, ethical and theological problems than this Saint of the Thirteenth Century. His position in the matter would only seem exaggerated to those who do not appreciate Pope Leo's marvelous practical intelligence, and Saint Thomas's exhaustive treatment of most of the questions that have always been uppermost in the minds of men. While, with characteristic humility, he considered himself scarcely more than a commentator on Aristotle, his natural genius was eminently original and he added much more of his own than what he took from his master. There can be no doubt that his was one of the most gifted minds in all humanity's history and that for profundity of intelligence he deserves to be classed with Plato and Aristotle, as his great disciple Dante is placed between Homer and Shakespeare. Those who know St. Thomas the best, and have spent their lives in the study of him, not only cordially welcomed but ardently applauded Pope Leo's commendation of him, and considered that lofty as was his praise there was not a word they would have changed even in such a laudatory passage as the following: "While, therefore, we hold that every word of wisdom, every useful thing by whomsoever discovered or planned, ought to be received with a willing and grateful mind. We exhort you, Venerable Brethren, in all earnestness to restore the golden wisdom of St. Thomas, and to spread it far and wide for the defense and beauty of the Catholic faith, for the good of society, and for the advantage of all the sciences. The wisdom of St. Thomas, We say--for if anything is taken up with too great subtlety by the scholastic doctors, or too carelessly stated--if there is anything that ill agrees with the discoveries of a later age, or, in a word, improbable in whatever way, it does not enter Our mind, to propose that for imitation to Our age. Let carefully selected teachers endeavor to implant the doctrines of Thomas Aquinas in the minds of students, and set forth clearly his solidity and excellence over others. Let the academies already founded or to be founded by you illustrate and defend this doctrine, and use it for refutation of prevailing errors. But, lest the false for the true or the corrupt for the pure be drunk in, be watchful that the doctrine of Thomas {281} be drawn from his own fountains, or at least from those rivulets which derived from the very fount, have thus far flowed, according to the established agreement of learned men, pure and clear; be careful to guard the minds of youth from those which are said to flow thence, but in reality are gathered from strange and unwholesome streams."
