Famous quotes containing the words visual and/or companions:

    The visual is sorely undervalued in modern scholarship. Art history has attained only a fraction of the conceptual sophistication of literary criticism.... Drunk with self-love, criticism has hugely overestimated the centrality of language to western culture. It has failed to see the electrifying sign language of images.
    Camille Paglia (b. 1947)

    The poet is no tender slip of fairy stock, who requires peculiar institutions and edicts for his defense, but the toughest son of earth and of Heaven, and by his greater strength and endurance his fainting companions will recognize the God in him. It is the worshipers of beauty, after all, who have done the real pioneer work of the world.
    Henry David Thoreau (1817–1862)
