Where would you have put the Fool in 1909 if you were honoring your oath not to reveal the GD's greatest secret (the placement of the Fool as 0=Aleph)?
It is not so much a "blind" as a following of tarot occult tradition up to that point. Since the Fool was unnumbered people could, in actuality, place it wherever they wished. However, he couldn't resist switching Justice and Strength because that would have set everything off. He made the deck useful to those who knew the GD secrets, while keeping to his oath. I think it was pretty ingenious.
