“It is questionable whether there does not exist in man an obscure and blind will to make war; an impulse towards change, towards emergence from the familiarities of everyday life and from the stabilities of well-known conditions — something like a will to death as a will to annihilation and self-sacrifice, a vague enthusiasm for the upbuilding of a new world.”

Context: All religions, arts and sciences are branches of the same tree. All these aspirations are directed toward ennobling man's life, lifting it from the sphere of mere physical existence and leading the individual towards freedom. It is no mere chance that our older universities developed from clerical schools. Both churches and universities — insofar as they live up to their true function — serve the ennoblement of the individual. They seek to fulfill this great task by spreading moral and cultural understanding, renouncing the use of brute force.
The essential unity of ecclesiastical and secular institutions was lost during the 19th century, to the point of senseless hostility. Yet there was never any doubt as to the striving for culture. No one doubted the sacredness of the goal. It was the approach that was disputed.
