### Famous quotes containing the word function:

To look backward for a while is to refresh the eye, to restore it, and to render it the more fit for its prime function of looking forward.
Margaret Fairless Barber (1869–1901)

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)

No one, however powerful and successful, can function as an adult if his parents are not satisfied with him.
Frank Pittman (20th century)
