“The 'concupiscence of the eyes' reaches its utmost destructive and extirpative power at the point where it has constructed for itself a world in its own image and likeness, where it has surrounded itself with the restlessness of a ceaseless film of meaningless objects for show and with a literally deafening noise of nothing more than impressions and sensations that roar in an uninterrupted chase around every window of the senses. Behind their papery facade of ostentation lies absolute nothingness, a 'world' of at most one day constructs that often become insipid after just one-quarter of an hour and are thrown out like a newspaper that has been read or a magazine that has been paged through; a world which, before the revealing gaze of a sound spirit uninfected by its contagion, shows itself to be like a metropolitan entertainment district in the harsh clarity of a winter morning: barren, bleak, and ghostly to the point of pushing one to despair.
Still, the destructive element of this disorder, born out of and shaped by illness, is found in the fact that this disorder obstructs the original power of man to perceive reality, that it renders a person unable not only to attain his own self but also to attain reality and truth.
If, therefore, a fraudulent world of this kind threatens to overrun and conceal the world of reality, then the cultivation of the natural desire to see assumes the character of a measure of self-preservation and self-defense. And then studiositas (diligence) means especially this: that a person resists the nearly inescapable temptation to indiscipline with all the power of self-protection, that he radically closes off the inner space of his life against the pressingly unruly pseudoreality of empty sights and sounds-in order that, through and only through this asceticism of perception, he might safeguard or recoup that which truly constitutes man's living existence: to perceive the reality of God and of creation and to shape himself and the world by the truth that discloses itself only in silence.”
