### Famous quotes containing the word function:

For me being a poet is a job rather than an activity. I feel I have a function in society, neither more nor less meaningful than any other simple job. I feel it is part of my work to make poetry more accessible to people who have had their rights withdrawn from them.
Jeni Couzyn (b. 1942)

If the children and youth of a nation are afforded opportunity to develop their capacities to the fullest, if they are given the knowledge to understand the world and the wisdom to change it, then the prospects for the future are bright. In contrast, a society which neglects its children, however well it may function in other respects, risks eventual disorganization and demise.
Urie Bronfenbrenner (b. 1917)

The function of the actor is to make the audience imagine for the moment that real things are happening to real people.
George Bernard Shaw (1856–1950)
