But the most memorable body of men that adorned these ages, were the Schoolmen. They may be considered as the discoverers of the art of logic. The ancients possessed in an eminent degree the gift of genius; but they have little to boast on the score of arrangement, and discover little skill in the strictness of an accurate deduction. They rather arrive at truth by means of a felicity of impulse, than in consequence of having regularly gone through the process which leads to it. The schools of the middle ages gave birth to the Irrefragable and the Seraphic doctors, the subtlety of whose distinctions, and the perseverance of whose investigations, are among the most wonderful monuments of the intellectual power of man. The thirteenth century produced Thomas Aquinas, and Johannes Duns Scotus, and William Occam, and Roger Bacon. In the century before, Thomas a Becket drew around him a circle of literary men, whose correspondence has been handed down to us, and who deemed it their proudest distinction that they called each other philosophers. The Schoolmen often bewildered themselves in their subtleties, and often delivered dogmas and systems that may astonish the common sense of unsophisticated understandings. But such is man. So great is his persevering labour, his invincible industry, and the resolution with which he sets himself, year after year, and lustre after lustre, to accomplish the task which his judgment and his zeal have commanded him to pursue. But I return to the question of literary fame. All these men, and men of a hundred other classes, who laboured most commendably and gallantly in their day, may be considered as swept away into the gulph of oblivion. As Swift humorously says in his Dedication to Prince Posterity, "I had prepared a copious list of Titles to present to your highness, as an undisputed argument of the prolificness of human genius in my own time: the originals were posted upon all gates and corner's of streets: but, returning in a very few hours to take a review, they were all torn down, and fresh ones put in their places. I enquired after them among readers and booksellers, but in vain: the memorial of them was lost among men; their place was no more to be found."
