We're buying this, but why do you sing the same sad songs all women sing?
(Katharine S. White (1892-1977), U.S. editor and book reviewer. As quoted in Onward and Upward, Prologue, by Linda H. Davis (1986).
White, Fiction Editor of the New York Times, sent this note to Phyllis McGinley in the 1940s, along with a check, when buying a skillful, but conventional, story she had submitted. According to McGinley's daughter, she later said "repeatedly" that this had "changed the direction of her whole career.")
Considered in its entirety, psychoanalysis won't do. It's an end product, moreover, like a dinosaur or a zeppelin; no better theory can ever be erected on its ruins, which will remain for ever one of the saddest and strangest of all landmarks in the history of twentieth-century thought.
(Peter B. Medawar (1915-1987), British immunologist. "Further Comments on Psychoanalysis," The Hope of Progress (1972).)
