From about the year 1100 conditions began to be more and more favorable to the revival of intellectual ambition, a recovery of forgotten knowledge, and a gradual accumulation of new information and inventions unknown to the Greeks, or indeed to any previous civilization. The main presuppositions of this third period of the later Middle Ages go back, however, to the Roman Empire. They had been formulated by the Church Fathers, transmitted through the Dark Age, and were now elaborated by the professors in the newly established universities under the influence of Aristotle's recovered works and built up into a majestic intellectual structure known as Scholasticism. On these mediaeval university professors--the schoolmen--Lord Bacon long ago pronounced a judgment that may well stand to-day. "Having sharp and strong wits, and abundance of leisure, and small variety of reading, but their wits being shut up in the cells of a few authors (chiefly Aristotle, their dictator), as their persons were shut up in the cells of monasteries and colleges, and knowing little history, either of nature or time [they], did out of no great quantity of matter and infinite agitation of wit spin out unto us those laborious webs of learning which are extant in their books." Our civilization and the human mind, critical and uncritical, as we now find it in our western world, is a direct and uninterrupted outgrowth of the civilization and thought of the later Middle Ages. Very gradually only did peculiarly free and audacious individual thinkers escape from this or that mediaeval belief, until in our own day some few have come to reject practically all the presuppositions on which the Scholastic system was reared. But the great mass of Christian believers, whether Catholic or Protestant, still professedly or implicitly adhere to the assumptions of the Middle Ages, at least in all matters in which religious or moral sanctions are concerned. It is true that outside the Catholic clergy the term "mediaeval" is often used in a sense of disparagement, but that should not blind us to the fact that mediaeval presumptions, whether for better or worse, are still common. A few of the most fundamental of these presuppositions especially germane to our theme may be pointed out here. 11. OUR MEDIAEVAL INTELLECTUAL INHERITANCE
