Famous quotes containing the words ladder and/or diagram:

    “O, when degree is shaked,
    Which is the ladder of all high designs,
    The enterprise is sick. How could communities,
    Degrees in schools, and brotherhoods in cities,
    Peaceful commerce from dividable shores,
    The primogeniture and due of birth,
    Prerogative of age, crowns, scepters, laurels,
    But by degree stand in authentic place?
    Take but degree away, untune that string,
    And hark what discord follows. Each thing meets
    In mere oppugnancy.”
    —William Shakespeare (1564–1616)

    “If a fish is the movement of water embodied, given shape, then cat is a diagram and pattern of subtle air.”
    —Doris Lessing (b. 1919)
