These are just assertions, there is no proof offered. And for a "forged" pamphlet it did seem to predict the general direction of "social progress". You could claim it as a forgery then maybe, but not now. You would think if it were a forgery those defamed by it would be spending great effort to ensure everything it posed as a plan of action never happened, and yet, here we are, watching them play out point by point. Nobody can read them and think "forgery", best I can do is "clairvoyant forger"
