I am, and always have been, a revolutionary writer, because our laws make law impossible; our liberties destroy all freedom; our property is organized robbery; our morality is an impudent hypocrisy; our wisdom is administered by inexperienced or mal-experienced dupes, our power wielded by cowards and weaklings, and our honor false in all its points. I am an enemy of the existing order for good reasons.
