Zeal for the classics was a result as well as a cause of the growing secular view of life. Expansion of trade, growth of prosperity and luxury, and widening social contacts generated interest in worldly pleasures, in spite of formal allegiance to ascetic Christian doctrine. Historians are pretty much agreed on the general outlines of those mental attitudes and scholarly interests which are assembled under the rubric of humanism. The most fundamental point of agreement is that the humanist mentality stood at a point midway between medieval supernaturalism and the modern scientific and critical attitude. Medievalists see humanism as the terminal product of the Middle Ages.
Modern historians are perhaps more apt to view humanism as the germinal period of modernism.
Perhaps the most we can assume is that the man of the Renaissance lived, as it were, between two worlds. The world of the medieval Christian matrix, in which the significance of every phenomenon was ultimately determined through uniform points of view, no longer existed for him. On the other hand, he had not yet found in a system of scientific concepts and social principles stability and security for his life. In other words, Renaissance man may indeed have found himself suspended between faith and reason. As the grip of medieval supernaturalism began to diminish, secular and human interests became more prominent.
