Famous quotes containing the words function, theory and/or representing:

    As a medium of exchange,... worrying regulates intimacy, and it is often an appropriate response to ordinary demands that begin to feel excessive. But from a modernized Freudian view, worrying—as a reflex response to demand—never puts the self or the objects of its interest into question, and that is precisely its function in psychic life. It domesticates self-doubt.
    Adam Phillips, British child psychoanalyst. “Worrying and Its Discontents,” in On Kissing, Tickling, and Being Bored, p. 58, Harvard University Press (1993)

    A theory if you hold it hard enough
    And long enough gets rated as a creed....
    Robert Frost (1874–1963)

    ... today we round out the first century of a professed republic,—with woman figuratively representing freedom—and yet all free, save woman.
    Phoebe W. Couzins (1845–1913)
