Famous quotes containing the word values:

    —Anita Loos (1888–1981)

    “The return to solid values is always hard.... Distress, panic, and hard times have marked our pathway in returning to solid values.”
    —James A. Garfield (1831–1881)

    “Normality highly values its normal man. It educates children to lose themselves and to become absurd, and thus to be normal. Normal men have killed perhaps 100,000,000 of their fellow normal men in the last fifty years.”
