Famous quotes containing the words water, pressure and/or difference:

Chief among them is the pressure for early intellectual attainment, deriving from a changed perception of precocity. Several decades ago precocity was looked upon with great suspicion. The child prodigy, it was thought, turned out to be a neurotic adult; thus the phrase “early ripe, early rot!”
    David Elkind (20th century)

    ... if the Settlement seeks its expression through social activity, it must learn the difference between mere social unrest and spiritual impulse.
    Jane Addams (1860–1935)
