“But what is the use of the humanities as such? Admittedly they are not practical, and admittedly they concern themselves with the past. Why, it may be asked, should we engage in impractical investigations, and why should we be interested in the past?

The answer to the first question is: because we are interested in reality. Both the humanities and the natural sciences, as well as mathematics and philosophy, have the impractical outlook of what the ancients called vita contemplativa as opposed to vita activa. But is the contemplative life less real or, to be more precise, is its contribution to what we call reality less important, than that of the active life?

The man who takes a paper dollar in exchange for twenty-five apples commits an act of faith, and subjects himself to a theoretical doctrine, as did the mediaeval man who paid for indulgence. The man who is run over by an automobile is run over by mathematics, physics and chemistry. For he who leads the contemplative life cannot help influencing the active, just as he cannot prevent the active life from influencing his thought. Philosophical and psychological theories, historical doctrines and all sorts of speculations and discoveries, have changed, and keep changing, the lives of countless millions. Even he who merely transmits knowledge or learning participates, in his modest way, in the process of shaping reality - of which fact the enemies of humanism are perhaps more keenly aware than its friends. It is impossible to conceive of our world in terms of action alone. Only in God is there a "Coincidence of Act and Thought" as the scholastics put it. Our reality can only be understood as an interpenetration of these two.”

“These two developments throw light on what is perhaps the most fundamental difference between the Renaissance and all previous periods of art. We have repeatedly seen that there were these circumstances which could compel the artist to make a distinction between the "technical" proportions and the "objective;" the influence of organic movement, the influence of perspective foreshortening, and the regard for the visual impression of the beholder. These three factors of variation have one thing in common: they all presuppose the artistic recognition of subjectivity. Organic movement introduces into the calculus of artistic composition the subjective will and the subjective emotions of the thing represented; foreshortening the subjective visual experience of the artist; and those "eurhythmic" adjustments which alter that which is right in favor of what seems right, the subjective visual experience of a potential beholder. And it is the Renaissance which, for the first time, not only affirms but formally legitimizes and rationalizes these three forms of subjectivity.”
