What is underlying instrument?

Famous quotes containing the words underlying and/or instrument:

    If the worker and his boss enjoy the same television program and visit the same resort places, if the typist is as attractively made up as the daughter of her employer, if the Negro owns a Cadillac, if they all read the same newspaper, then this assimilation indicates not the disappearance of classes, but the extent to which the needs and satisfactions that serve the preservation of the Establishment are shared by the underlying population.
    Herbert Marcuse (1898–1979)

    There is a hearty Puritanism in the view of human nature which pervades the instrument of 1787. It is the work of men who believed in original sin, and were resolved to leave open for transgressors no door which they could possibly shut.
    James Bryce (1838–1922)
