"Do you believe,” said Candide, “that men have always massacred each other as they do to-day, that they have always been liars, cheats, traitors, ingrates, brigands, idiots, thieves, scoundrels, gluttons, drunkards, misers, envious, ambitious, bloody-minded, calumniators, debauchees, fanatics, hypocrites, and fools?”

“Do you believe,” said Martin, “that hawks have always eaten pigeons when they have found them?”

“Yes, without doubt,” said Candide.

“Well, then,” said Martin, “if hawks have always had the same character why should you imagine that men may have changed theirs?"
