madame bovary by gustave flaubert

"Because lips libertine and venal had murmured such words to him, he believed but little in the candor of hers; exaggerated speeches hiding mediocre affections must be discounted; as if the fullness of the soul did not sometimes overflow in the emptiest metaphors, since no one can ever give the exact measure of his needs, nor of his conceptions, nor of his sorrows; and since human speech is like a cracked tin kettle, on which we hammer out tunes to make bears dance when we long to move the stars."
