Famous quotes containing the word purpose:
“Whoever considers morality the main objective of human existence, seems to me like a person who defines the purpose of a clock as not going wrong. The first objective for a clock, is, however, that it does run; not going wrong is an additional regulative function. If not a watch’s greatest accomplishment were not going wrong, unwound watches might be the best.”
—Franz Grillparzer (1791–1872)
“No further evidence is needed to show that “mental illness” is not the name of a biological condition whose nature awaits to be elucidated, but is the name of a concept whose purpose is to obscure the obvious.”
—Thomas Szasz (b. 1920)
“Civilization is a process in the service of Eros, whose purpose is to combine single human individuals, and after that families, then races, peoples and nations, into one great unity, the unity of mankind. Why this has to happen, we do not know; the work of Eros is precisely this.”
—Sigmund Freud (1856–1939)
