Famous quotes containing the words difference and/or set:

    The difference between writing a book and being on television is the difference between conceiving a child and having a baby made in a test tube.
    Norman Mailer (b. 1923)

    Women are to be lifted up to a physical equality with man by placing upon their shoulders equal burdens of labor, equal responsibilities of state-craft; they are to be brought down from their altruistic heights by being released from all obligations of purity, loyalty, self-sacrifice, and made free of the world of passion and self-indulgence, after the model set them by men of low and materialistic ideals.
    Caroline Fairfield Corbin (b. c. 1835–?)
