Famous quotes containing the word dangers:
“Anyone with a real taste for solitude who indulges that taste encounters the dangers of any other drug-taker. The habit grows. You become an addict.... Absorbed in the visions of solitude, human beings are only interruptions. What voice can equal the voices of solitude? What sights equal the movement of a single day’s tide of light across the floor boards of one room? What drama be as continuously absorbing as the interior one?”
—Jessamyn West (1902–1984)
“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)
“The sun of Rome is set. Our day is gone;
Clouds, dews, and dangers come; our deeds are done.”
—William Shakespeare (1564–1616)
