### Famous quotes containing the word function:

“The press and politicians. A delicate relationship. Too close, and danger ensues. Too far apart and democracy itself cannot *function* without the essential exchange of information. Creative leaks, a discreet lunch, interchange in the Lobby, the art of the unattributable telephone call, late at night.”

—Howard Brenton (b. 1942)

“Uses are always much broader than functions, and usually far less contentious. The word *function* carries overtones of purpose and propriety, of concern with why something was developed rather than with how it has actually been found useful. The *function* of automobiles is to transport people and objects, but they are used for a variety of other purposes—as homes, offices, bedrooms, henhouses, jetties, breakwaters, even offensive weapons.”

—Frank Smith (b. 1928)

“The more books we read, the clearer it becomes that the true *function* of a writer is to produce a masterpiece and that no other task is of any consequence.”

—Cyril Connolly (1903–1974)
