When one is in love one begins by deceiving oneself. And one ends by deceiving others. That is what the world calls a romance.
We always deceive ourselves twice about the people we love – first to their advantage, then to their disadvantage.
People are easily duped by those whom they love, and conceit is apt to deceive itself.[On est aifément dupé par ce qu’on aime; Et l’amour-propre engage à fe tromper foi-même.]
