In the wind of the mind arises the turbulence called I. It breaks; down shower the barren thoughts. All life is choked. This desert is the abyss wher… - Aleister Crowley

Black magic is not a myth. It is a totally unscientific and emotional form of magic, but it does get results — of an extremely temporary nature. The recoil upon those who practice it is terrific. It is like looking for an escape of gas with a lighted candle. As far as the search goes, there is little fear of failure!
To practice black magic you have to violate every principle of science, decency, and intelligence. You must be obsessed with an insane idea of the importance of the petty object of your wretched and selfish desires. I have been accused of being a "black magician." No more foolish statement was ever made about me. I despise the thing to such an extent that I can hardly believe in the existence of people so debased and idiotic as to practice it.

Adaptation to one's environment makes for a sort of survival; but after all, the supreme victory is only won by those who prove themselves of so much hardier stuff than the rest that no power on earth is able to destroy them. The people who have really made history are the martyrs.

We know one thing only. Absolute existence, absolute motion, absolute direction, absolute simultaneity, absolute truth, all such ideas: they have not, and never can have, any real meaning. If a man in delirium tremens fell into the Hudson River, he might remember the proverb and clutch at an imaginary straw. Words such as "truth" are like that straw. Confusion of thought is concealed, and its impotence denied, by the invention. This paragraph opened with "We know": yet, questioned, "we" make haste to deny the possibility of possessing, or even of defining, knowledge. What could be more certain to a parabola-philosopher that he could be approached in two ways, and two only? It would be indeed little less that the whole body of his knowledge, implied in the theory of his definition of himself, and confirmed by every single experience. He could receive impressions only be meeting A, or being caught up by B. Yet he would be wrong in an infinite number of ways. There are therefore Aleph-Zero possibilities that at any moment a man may find himself totally transformed. And it may be that our present dazzled bewilderment is due to our recognition of the existence of a new dimension of thought, which seems so "inscrutably infinite" and "absurd" and "immoral," etc. — because we have not studied it long enough to appreciate that its laws are identical with our own, though extended to new conceptions.
