Famous quotes containing the word features:

    ““It looks as if
    Some pallid thing had squashed its features flat
    And its eyes shut with overeagerness
    To see what people found so interesting
    In one another, and had gone to sleep
    Of its own stupid lack of understanding,
    Or broken its white neck of mushroom stuff
    Short off, and died against the windowpane.””
    —Robert Frost (1874–1963)

    “These, then, will be some of the features of democracy ... it will be, in all likelihood, an agreeable, lawless, particolored commonwealth, dealing with all alike on a footing of equality, whether they be really equal or not.”
    —Plato (c. 427–347 B.C.)

    “Art is the child of Nature; yes,
    Her darling child, in whom we trace
    The features of the mother’s face,
    Her aspect and her attitude.”
    —Henry Wadsworth Longfellow (1807–1882)
