Famous quotes containing the words channels and/or covert:

    People between twenty and forty are not sympathetic. The child has the capacity to do but it can’t know. It only knows when it is no longer able to do—after forty. Between twenty and forty the will of the child to do gets stronger, more dangerous, but it has not begun to learn to know yet. Since his capacity to do is forced into channels of evil through environment and pressures, man is strong before he is moral. The world’s anguish is caused by people between twenty and forty.
    William Faulkner (1897–1962)

    There was the murdered corpse, in covert laid,
    And violent death in thousand shapes displayed;
    The city to the soldier’s rage resigned;
    Successless wars, and poverty behind;
    Ships burnt in fight, or forced on rocky shores,
    And the rash hunter strangled by the boars;
    The newborn babe by nurses overlaid;
    And the cook caught within the raging fire he made.
    Geoffrey Chaucer (1340?–1400)
