Famous quotes containing the words visual, disturbances and/or blindness:
“To write well, to have style ... is to paint. The master faculty of style is therefore the visual memory. If a writer does not see what he describes—countrysides and figures, movements and gestures—how could he have a style, that is originality?”
—Rémy De Gourmont (1858–1915)
“I note what you say of the late disturbances in your College. These dissensions are a great affliction on the American schools, and a principal impediment to education in this country.”
—Thomas Jefferson (1743–1826)
“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)
