Your friends will notice at once that glib vacuities fail to impress, and hate you, and tell lies about you. It's worth it.

It sometimes strikes me that the whole of science is a piece of impudence; that nature can afford to ignore our impertinent interference. If our monkey mischief should ever reach the point of blowing up the earth by decomposing an atom, and even annihilated the sun himself, I cannot really suppose that the universe would turn a hair.

The pious pretense that evil does not exist only makes it vague, enormous and menacing.

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.

I admit that my visions can never mean to other men as much as they do to me. I do not regret this. All I ask is that my results should convince seekers after truth that there is beyond doubt something worth while seeking, attainable by methods more or less like mine. I do not want to father a flock, to be the fetish of fools and fanatics, or the founder of a faith whose followers are content to echo my opinions. I want each man to cut his own way through the jungle.

Having to talk destroys the symphony of silence.

For pure will, unassuaged of purpose, delivered from the lust of result, is every way perfect.
