### 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 mother’s and father’s attitudes toward the child correspond to the child’s own needs.... Mother has the *function* of making him secure in life, father has the *function* of teaching him, guiding him to cope with those problems with which the particular society the child has been born into confronts him.”

—Erich Fromm (1900–1980)

“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)
