Famous quotes containing the words features of the, features of and/or features:

    “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)

    “The features of our face are hardly more than gestures which force of habit made permanent. Nature, like the destruction of Pompeii, like the metamorphosis of a nymph into a tree, has arrested us in an accustomed movement.”
    —Marcel Proust (1871–1922)

    “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.)
