"The truth is that the imbalances under which the modern world labors are linked with that more basic imbalance which is rooted in the heart of man. For in man himself many elements wrestle with one another. Thus, on the one hand, as a creature he experiences his limitations in a multitude of ways; on the other he feels himself to be boundless in his desires and summoned to a higher life. Pulled by manifold attractions he is constantly forced to choose among them and renounce some."
