Some thoughts on the Kerubic/Zodiacal attributions.
Crowley, at least in Liber Aleph, uses the same attributions as Levi, at least in History of Magig. But others have attributed them like this (Crowley/Levi in parentheses):
To Know: Aquarius (Aquarius)
To Dare: Scorpio (Leo)
To Will: Leo (Taurus)
To be Silent: Taurus (Scorpio)
It seems that, by drawing on the zodica lore/meaning/whatever, that we might come up with some different understandings of the 4 powers by switching the attributes around.
(Keep in mind that I still have quite far to go in developing my intellectual and intuitive understandings of the zodiac) For example, Will seems more like will in the lower-case sense, in the sense of will power, or in Levi's sense of will with regard to magic when we understand will through Leo. Leo's exert their will in the world to organize others to create the world they want around them. But Will seems more like True Will - the Hiden Will - when understood through Taurus. The Hidden Will, the "Marvelous Seed of the Stars" (Prayer of the Gnomes, Levi) remains hidden within the earth (Taurus). I can't really explain the relationship between Taurus and the True Will better intellectually. I grasp it more intuitively, or, if you prefer, half-assed.
Another quick thought... Perhaps To Dare relates better to the scorpion (the transformer?) of Scorpio, while Silence ("the silence of the end") relates better to the eagle (the transformed?) of Scorpio.
Getting to the point, it seems useful to switch these things around to get other perspectives on them.
