Famous quotes containing the words fatigue and/or cracking:
“He is asleep. He knows no longer the fatigue of the work of deciding, the work to finish. He sleeps, he has no longer to strain, to force himself, to require of himself that which he cannot do. He no longer bears the cross of that interior life which proscribes rest, distraction, weaknesshe sleeps and thinks no longer, he has no more duties or chores, no, no, and I, old and tired, oh! I envy that he sleeps and will soon die.”
—Albert Camus (1913–1960)
“Hume’s doctrine was that the circumstances vary, the amount of happiness does not; that the beggar cracking fleas in the sunshine under a hedge, and the duke rolling by in his chariot; the girl equipped for her first ball, and the orator returning triumphant from the debate, had different means, but the same quantity of pleasant excitement.”
—Ralph Waldo Emerson (1803–1882)
