Famous quotes containing the word proof:

    When children feel good about themselves, it’s like a snowball rolling downhill. They are continually able to recognize and integrate new proof of their value as they grow and mature.
    Stephanie Martson (20th century)

    a meek humble Man of modest sense,
    Who preaching peace does practice continence;
    Whose pious life’s a proof he does believe,
    Mysterious truths, which no Man can conceive.
    John Wilmot, 2d Earl Of Rochester (1647–1680)

    To cease to admire is a proof of deterioration.
    Charles Horton Cooley (1864–1929)
