"In law we draw a line between the killing of human animals and non-human ones, setting the latter apart as brutes. This was founded on a general belief that humans have immortal souls and brutes none. Nowadays more and more people are refusing to make this distinction. They may believe in The Life Everlasting and The Life to Come; but they make no distinction between Man and Brute, because some of them believe that brutes have souls, whilst others refuse to believe that the physical materializations and personifications of The Life Everlasting are themselves everlasting. In either case the mystic distinction between Man and Brute vanishes; and the murderer pleading that though a rabbit should be killed for being mischievous he himself should be spared because he has an immortal soul and a rabbit has none is as hopelessly out of date as a gentleman duellist pleading his clergy. When the necessity for killing a dangerous human being arises, as it still does daily, the only distinction we make between a man and a snared rabbit is that we very quaintly provide the man with a minister of religion to explain to him that we are not killing him at all, but only expediting his transfer to an eternity of bliss."

“You don't learn to hold your own in the world by standing on guard, but by attacking, and getting well hammered yourself.”

“They have redeemed themselves from their vileness, and turned away from their sins. Best of all, they are still not satisfied: the impulse I gave them in that day when I sundered myself in twain and launched Man and Woman on the earth still urges them: after passing a million goals they press on to the goal of redemption from the flesh, to the vortex freed from matter, to the whirlpool in pure intelligence that, when the world began, was a whirlpool in pure force.”

“Everything is possible: everything. Listen. I am old. I am the old serpent, older than Adam, older than Eve. I remember Lilith, who came before Adam and Eve. I was her darling as I am yours. She was alone: there was no man with her. She saw death as you saw it when the fawn fell; and she knew then that she must find out how to renew herself and cast the skin like me. She had a mighty will: she strove and strove and willed and willed for more moons than there are leaves on all the trees of the garden. Her pangs were terrible: her groans drove sleep from Eden. She said it must never be again: that the burden of renewing life was past bearing: that it was too much for one. And when she cast the skin, lo! there was not one new Lilith but two: one like herself, the other like Adam. You were the one: Adam was the other.”
