Famous quotes containing the words visual, disturbances and/or blindness:
“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)
“When a poor disconsolated drooping creature is terrified from all enjoyment,—prays without ceasing ‘till his imagination is heated,—fasts and mortifies and mopes, till his body is in as bad a plight as his mind; is it a wonder, that the mechanical disturbances ... of an empty belly, interpreted by an empty head, should be mistook for [the] workings [of God].”
—Laurence Sterne (1713–1768)
“Oh blindness to the future! kindly giv’n,
That each may fill the circle mark’d by Heav’n:”
—Alexander Pope (1688–1744)
