Crowley's swap seems to correct the attribution to the text of the Thirty-Two Paths of Wisdom.
The text for the 15th path and it's traditional Golden Dawn attribution of the Emperor reads:
The Fifteenth Path is the Constituting Intelligence, so called because it constitutes the substance of creation in pure darkness, and men have spoken of these contemplations; it is that darkness spoken of in scripture, Job xxxviii. 9, "and thick darkness a swaddling band for it."
To me the Star is a much better fit for that text than the Emperor. Equally the text for the 28th path seems to correspond better to the Emperor than it's traditional attribution to the Star:
The Twenty-eighth Path is the Natural Intelligence, and is so called because through it is consummated and perfected the nature of every existent being under the orb of the Sun, in perfection.
So far Crowley's swap is all well and good and seems to have smoothed out all the little problems in the Golden Dawn attributions. But in the act of solving one problem it creates another.
Crowley says that the Emperor is attributed the astrological sign of Aries and placed on the 28th path, and the Star is Aquarius and placed on the 15th. This breaks with the Yetziratic tradition that says that Heh = Aries = 15th path. Tzaddi = Aquarius = 28th path.
When you swap the astrological signs around to conform with their respective cards, they don't seem to fit any more. This is quite frustrating. I mean, Aries on the 28th path between Yesod and Netzach! How does that work? I can understand the placement of the Emperor there but not the sign of Aries. It just doesn't fit.
Crowley's swap seems to solve one problem by creating another. Are Crowley's apparent mix ups in the Book of Thoth intended to show that both old and new attributions are correct?
