Famous quotes containing the words screen and/or viewing:

    “Every obstruction of the course of justice,—is a door opened to betray society, and bereave us of those blessings which it has in view.... It is a strange way of doing honour to God, to screen actions which are a disgrace to humanity.”
    —Laurence Sterne (1713–1768)

    “A lover is never a completely self-reliant person viewing the world through his own eyes, but a hostage to a certain delusion. He becomes a perjurer, all his thoughts and emotions being directed with reference, not to an accurate and just appraisal of the real world but rather to the safety and exaltation of his loved one, and the madness with which he pursues her, transmogrifying his attention, blinds him like a victim.”
    —Alexander Theroux (b. 1940)
