The pleasure which escapes them changes itself for them into a long irritation and desire. The more murderous are their excesses, the more it seems to them that supreme happiness is at hand. … One more bumper of strong drink, one more spasm, one more violence done to Nature… Ah! at last, here is pleasure; here is life … and their desire, in the paroxysm of its insatiable hunger, extinguishes itself for ever in death.
Éliphas Lévi, trans Aleister Crowley, Liber XLVI The Key of the Mysteries
