### Famous quotes containing the word function:

“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)

“The *function* of literature, through all its mutations, has been to make us aware of the particularity of selves, and the high authority of the self in its quarrel with its society and its culture. Literature is in that sense subversive.”

—Lionel Trilling (1905–1975)

“The art of living is to *function* in society without doing violence to one’s own needs or to the needs of others. The art of mothering is to teach the art of living to children.”

—Elaine Heffner (20th century)
