Marginal Revenue Function

Famous quotes containing the words marginal, revenue and/or function:

    If the individual, or heretic, gets hold of some essential truth, or sees some error in the system being practised, he commits so many marginal errors himself that he is worn out before he can establish his point.
    Ezra Pound (1885–1972)

    Happy are those who find wisdom, and those who get understanding, for her income is better than silver, and her revenue better than gold. She is more precious than jewels, and nothing you desire can compare with her. Long life is in her right hand; in her left hand are riches and honor. Her ways are ways of pleasantness, and all her paths are peace. She is a tree of life to those who lay hold of her; those who hold her fast are called happy.
    Bible: Hebrew, Proverbs 3:13-18.

    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)
