Famous quotes containing the words orders and/or magnitude:

    God is a foreman with certain definite views
    Who orders life in shifts of work and leisure.
    Seamus Heaney (b. 1939)

    Constancy has nothing virtuous in itself, independently of the pleasure it confers, and partakes of the temporizing spirit of vice in proportion as it endures tamely moral defects of magnitude in the object of its indiscreet choice.
    Percy Bysshe Shelley (1792–1822)
