Famous quotes containing the word function:

    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)

    Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.
    Susanne K. Langer (1895–1985)

    “... The state’s one function is to give.
    The bud must bloom till blowsy blown
    Its petals loosen and are strown;
    And that’s a fate it can’t evade
    Unless ‘twould rather wilt than fade.”
    Robert Frost (1874–1963)
