Famous quotes containing the words visual, disturbances and/or blindness:
“Nowadays people’s visual imagination is so much more sophisticated, so much more developed, particularly in young people, that now you can make an image which just slightly suggests something, they can make of it what they will.”
—Robert Doisneau (b. 1912)
“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)
“For the “superior morality” of which we hear so much, we too would desire to be thankful: at the same time, it were but blindness to deny that this “superior morality” is properly rather an “inferior criminality” produced not by greater love of Virtue, but by greater perfection of Police; and of that far subtler and stronger Police, called Public Opinion.”
—Thomas Carlyle (1795–1881)
