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)
“Disappointment, when it involves neither shame nor loss, is as good as success; for it supplies as many images to the mind, and as many topics to the tongue.”
—Samuel Johnson (1709–1784)
“Wisdom and Spirit of the universe!
Thou Soul that art the eternity of thought,
That givest to forms and images a breath
And everlasting motion,”
—William Wordsworth (1770–1850)
