Famous quotes containing the word motions:
“We all run on two clocks. One is the outside clock, which ticks away our decades and brings us ceaselessly to the dry season. The other is the inside clock, where you are your own timekeeper and determine your own chronology, your own internal weather and your own rate of living. Sometimes the inner clock runs itself out long before the outer one, and you see a dead man going through the motions of living.”
—Max Lerner (b. 1902)
“A lover, when he is admitted to cards, ought to be solemnly silent, and observe the motions of his mistress. He must laugh when she laughs, sigh when she sighs. In short, he should be the shadow of her mind. A lady, in the presence of her lover, should never want a looking-glass; as a beau, in the presence of his looking-glass, never wants a mistress.”
—Henry Fielding (17071754)
“A painter told me that nobody could draw a tree without in some sort becoming a tree; or draw a child by studying the outlines of its forms merely,but by watching for a time his motions and plays, the painter enters into his nature and can then draw him at will in every attitude.”
—Ralph Waldo Emerson (18031882)
