### Famous quotes containing the word function:

“Every boy was supposed to come into the world equipped with a father whose prime *function* was to be our father and show us how to be men. He can escape us, but we can never escape him. Present or absent, dead or alive, real or imagined, our father is the main man in our masculinity.”

—Frank Pittman (20th century)

“To make us feel small in the right way is a *function* of art; men can only make us feel small in the wrong way.”

—E.M. (Edward Morgan)

“The fact remains that the human being in early childhood learns to consider one or the other aspect of bodily *function* as evil, shameful, or unsafe. There is not a culture which does not use a combination of these devils to develop, by way of counterpoint, its own style of faith, pride, certainty, and initiative.”

—Erik H. Erikson (1904–1994)
