Famous quotes containing the word dangers:
“One of the dangers of the American artist is that he finds himself almost exclusively thrown in with persons more or less in the arts. He lives among them, eats among them, quarrels with them, marries them.”
—Thornton Wilder (1897–1975)
“There was only one catch and that was Catch-22, which specified that a concern for one’s own safety in the face of dangers that were real and immediate was the process of a rational mind.... Orr would be crazy to fly more missions and sane if he didn’t, but if he was sane he had to fly them. If he flew them he was crazy and didn’t have to; but if he didn’t want to he was sane and had to.”
—Joseph Heller (b. 1923)
“Learning carries within itself certain dangers because out of necessity one has to learn from one’s enemies.”
—Leon Trotsky (1879–1940)
