Famous quotes containing the words biological and/or role:
“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)
“Man, truly the animal that talks, is the only one that needs conversations to propagate its species.... In love conversations play an almost greater role than anything else. Love is the most talkative of all feelings and consists to a great extent completely of talkativeness.”
—Robert Musil (1880–1942)
