Famous quotes containing the words negative and/or pressure:

    The idealist’s programme of political or economic reform may be impracticable, absurd, demonstrably ridiculous; but it can never be successfully opposed merely by pointing out that this is the case. A negative opposition cannot be wholly effectual: there must be a competing idealism; something must be offered that is not only less objectionable but more desirable.
    Charles Horton Cooley (1864–1929)

    Amid the pressure of great events, a general principle gives no help.
    Georg Wilhelm Friedrich Hegel (1770–1831)
