"My first appearance led me by a new path into another intellectual world, the simple and lofty economy of which I was unable to look upon without enthusiasm. My continued attention to it soon convinced me, that there was nothing but error and folly in the doctrine of our philosophers, and misery and oppression in our social arrangements. Deluded by my foolish pride, I thought that I was born to destroy all these illusions, and, believing that, in order to gain a hearing, it was necessary for my manner of life to harmonise with my principles, I adopted the singular course which I have not been permitted to continue, in which I set an example for which my pretended friends have never forgiven me, which at first made me ridiculous, and would have ended by making me respectable, if it had been possible for me to persevere in it."
