Logic is Occult

The darkest facts are the ones you can explain in detail and yet remain secret. 

Logic is the apotheosis. Nothing is darker.

Logic appears to be common knowledge, and yet it is still secret. You can give out explicit step-by-step recipes for logic and it remains secret. Nearly everyone can tell you Aristotle wrote down the first two laws of logic, and it remains secret. Hermes Trismegistus wrote down even more, mortals called themselves alchemists for millennia, and yet Alchemy remains secret.

Logic is the most occult art.
This secret keeps itself by the very nature of the gnosis. It is possible to recite their chapters and verses and still know less than nothing on the topic.

Here's the question: when the J-Satanists burnt all the alchemy books, were they helping, or wasting their time? If alchemists managed to write down any Alchemy, it still remained secret. First, no Alchemy was disseminated, then the books were burned, and as a result, no Alchemy was disseminated. Alternatively, it was secret to the authors as well, and as such the Church destroyed a bunch of blasphemy against Alchemy. Uhhh...thanks? You, uh, fucked up a bit there, Satan. Extremely in-character, I suppose. 

Honestly Trismegistus fucked up when he wrote it down in the first place. The Church merely corrected this error for him. Haha, oops!

I think it might actually be worse. Even if alchemists wrote down some legitimate Alchemy, explaining it causes greater ignorance. Instruction in Logic makes the student less logical, due to the interaction of the gnosis with the student's malicious nature.
A solution jumps to mind: if correct instruction leads to error, shouldn't a clever form of erroneous instruction lead to enlightenment? Haha, no. It is impossible to betray someone into being virtuous. You can't desecrate so deeply and profoundly it becomes a consecration. Simply not how that works.
Even if you manage to temporarily trick the dire ape into being logical, they will only use the logic to notice the contradiction between true thinking their ultimate teleology. They will notice it's counterproductive, and discard the gnosis. 

If Logic is not occult, nothing is occult.
