Famous quotes containing the word images:
“Those images that yet
Fresh images beget,
That dolphin-torn, that gong-tormented sea.”
—William Butler Yeats (1865–1939)
“The world is for thousands a freak show; the images flicker past and vanish; the impressions remain flat and unconnected in the soul. Thus they are easily led by the opinions of others, are content to let their impressions be shuffled and rearranged and evaluated differently.”
—Johann Wolfgang Von Goethe (1749–1832)
“As individuals and as a nation, we now suffer from social narcissism. The beloved Echo of our ancestors, the virgin America, has been abandoned. We have fallen in love with our own image, with images of our making, which turn out to be images of ourselves.”
—Daniel J. Boorstin (b. 1914)
