Edgar Allan Poe,
Bon-Bon
(1832)
“ It was by no means necessary to the satisfaction of the philosopher, that the bargain should be to his own proper advantage. Provided a trade could be effected—a trade of any kind, upon any terms, or under any circumstances—a triumphant smile was seen for many days thereafter to enlighten his countenance, and a knowing wink of the eye to give evidence of his sagacity. ”
