Famous quotes containing the words involving, changing, chemical, nature and/or acids:

    Living is like working out a long addition sum, and if you make a mistake in the first two totals you will never find the right answer. It means involving oneself in a complicated chain of circumstances.
    Cesare Pavese (1908–1950)

    Love is the most melodious of all the harmonies, and we have an innate feeling for it. Woman is a delicious instrument of pleasure, but one must know the chords, study the pose of it, the timid keyboard, the changing and capricious fingering.
    HonorĂ© De Balzac (1799–1850)

    We do not want actions, but men; not a chemical drop of water, but rain; the spirit that sheds and showers actions, countless, endless actions.
    Ralph Waldo Emerson (1803–1882)

    No further evidence is needed to show that “mental illness” is not the name of a biological condition whose nature awaits to be elucidated, but is the name of a concept whose purpose is to obscure the obvious.
    Thomas Szasz (b. 1920)

    The new American finds his challenge and his love in the traffic-choked streets, skies nested in smog, choking with the acids of industry, the screech of rubber and houses leashed in against one another while the townlets wither a time and die.
    John Steinbeck (1902–1968)
