Famous quotes containing the words patient, selection and/or warnings:
“Narcissist: psychoanalytic term for the person who loves himself more than his analyst; considered to be the manifestation of a dire mental disease whose successful treatment depends on the patient learning to love the analyst more and himself less.”
—Thomas Szasz (b. 1920)
“Every writer is necessarily a critic—that is, each sentence is a skeleton accompanied by enormous activity of rejection; and each selection is governed by general principles concerning truth, force, beauty, and so on.... The critic that is in every fabulist is like the iceberg—nine-tenths of him is under water.”
—Thornton Wilder (1897–1975)
“Logic and hope fade somewhat by thirty-six, when endings seem more like clear warnings than useful experience.”
—Jane O’Reilly, U.S. feminist and humorist. The Girl I Left Behind, ch. 2 (1980)
