Famous quotes containing the word images:
“For thousands the world is a freak show, the images flicker past and disappear, the impressions remain flat and disconnected in the soul. Thus, they are easily led by the opinions of others, are willing to let their impressions be reordered, rearranged, and reevaluated.”
—Johann Wolfgang Von Goethe (1749–1832)
“A daydream is a meal at which images are eaten. Some of us are gourmets, some gourmands, and a good many take their images precooked out of a can and swallow them down whole, absent-mindedly and with little relish.”
—W.H. (Wystan Hugh)
“Style a tablet at every noon time, Lady,
With bold images of a timid boy!”
—Allen Tate (1899–1979)
