What was meant by The Grand Fallacy the phrase was used in one of the science fiction novels of Julian May it was in a poster on the wall of a Lab in slogan form?

Answer 1

My Guess was it was the opening line in the Declaration of Independence- we hold these Truths to be self-evident, that All Men are Created Equal... Obviously this violated SS-Land policy with the Germans a Master Race. oddly in the May novel the slogan was never explained it went: We are experts, we avoid small errors as we sweep towards the Grand Fallacy. for many years I could not figure it out then recalling the many Nazi Rocket scientists- such as Von Braun, it made sense. allegdly the poster- with a V-2 being launched was found on the walls of a German Missile site in Peenemunde, perhaps.
