Famous quotes containing the word standards:

    “Barbarism is the absence of standards to which appeal can be made.”
    —José Ortega Y Gasset (1883–1955)

    “The technologist was the final guise of the white missionary, industrialization the last gospel of a dying race and living standards a substitute for a purpose in living.”
    —Max Frisch (1911–1991)

    “Men are rewarded for learning the practice of violence in virtually any sphere of activity by money, admiration, recognition, respect, and the genuflection of others honoring their sacred and proven masculinity. In male culture, police are heroic and so are outlaws; males who enforce standards are heroic and so are those who violate them.”
    —Andrea Dworkin (b. 1946)
