It ends, as might have been expected, in the ruin of it’s people, but this ruin will fall heaviest, as it ought to fall on that hereditary aristocracy which has for generations been preparing the catastrophe. I hope we shall take warning from the example and crush in it’s birth the aristocracy of our monied corporations which dare already to challenge our government to a trial of strength and bid defiance to the laws of our country.

Ma vie entière est un tissu de contrastes apparents avec mes principes. Je n'aime point les Princes, et je suis attaché à une Princesse et à un Prince. On me connaît des maximes républicaines, et plusieurs de mes amis sont revêtus de décorations monarchiques. J'aime la pauvreté volontaire, et je vis avec des gens riches. Je fuis les honneurs, et quelques-uns sont venus à moi. Les lettres sont presque ma seule consolation, et je ne vois point de beaux esprits, et ne vais point à l'Académie. Ajoutez que je crois les illusions nécessaires à l'homme, et je vis sans illusion; que je crois les passions plus utiles que la raison, et je ne sais plus ce que c'est que les passions, etc.
