Doubt even if thou doubtest thyself.
Doubt even if thou doubtest all.
It seems sometimes as if beneath all conscious doubt there lay some deepest certainty. O kill it! Slay the snake!
– Aleister Crowley, The Book of Lies , Ch. 51
I slept with faith and found a corpse in my arms on awakening;
I drank and danced all night with doubt and found her a virgin in the morning.
– Aleister Crowley, The Book of Lies , Ch. 44
In this book it is spoken… of Spirits and Conjurations; of Gods, Spheres, Planes, and many other things which may or may not exist. It is immaterial whether these exist or not. By doing certain things certain results will follow; students are most earnestly warned against attributing objective reality or philosophic validity to any of them.
