The companions of S. Thomas in Albert's school, were men filled with the impression that to exert the reasoning faculties in debating scholastic questions, was one of the principal ends of all philosophy. It is not extraordinary that such men as these, when they saw young Aquino so silent, should imagine that nothing occupied his thoughts; especially when they perceived that he was equally reserved in school. They soon came to the conclusion that he was a naturally obtuse lad. What is more strange is this,--that Albert at first held him to be deficient. He was called by master and pupils, "the great dumb Sicilian ox." Once, when studying in his cell, he heard a voice crying to him, "Brother Thomas, here! quick, look at this flying ox!" When S. Thomas went to the window, he was received with shouts of derision. In explanation he said incisively: "I did not believe an ox could fly, nor did I, till now, believe that a religious could tell a lie." A companion one day offered to assist him in his lesson. S. Thomas assented; presently his friend came to a hard passage, which was beyond his depth, the saint took the book from him, and explained the passage with great clearness. Albert had selected a difficult question from the writings of Dionysius the Areopagite; this the scholars passed to S. Thomas; he took it to his cell; and first stating all the objections that could be made against it, he then answered them. A brother picked up this paper, and carried it to Albert. His master ordered him to defend a thesis the next day before the whole school. Thomas spoke with such clearness, established his thesis with such dialectical skill, saw so far into the difficulties of the case, and handled the whole subject in so masterly a manner, that Albert exclaimed, "Thou seemest to me not to be defending the case, but to be deciding it." "Master," he replied, "I know not how to treat the question otherwise." Albert, to test him further, started objections, but Thomas solved every difficulty so successfully, that Albert cried out, "We call this youth 'Dumb Ox,' but the day will come when the whole world will resound with his bellowing."
