There is nothing very remarkable about being immortal; with the exception of mankind, all creatures are immortal, for they know nothing of death. What is divine, terrible and incomprehensible is to know oneself immortal.
I have noticed that in spite of religion, the conviction as to one's own immortality is extraordinarily rare. Jews, Christians, and Muslims all profess belief in immortality, but the veneration paid to the first century of life is proof that they truly believe only in those hundred years, for they destine all the rest, throughout eternity, to rewarding or punishing what one did when alive.
In my view, the Wheel conceived by certain religions in Hindustan is much more plausible; on that Wheel, which has neither end nor beginning, each life is the effect of the previous life and engenderer of the next, yet no one life determines the whole"
Taught by centuries of living, the republic of immortal men had achieved a perfection of tolerance, almost of disdain. They knew that over an infinitely long span of time, all things happen to all men. As reward for his past and future virtues, every man merited every kindness--yet also every betrayal, as reward for his past and future iniquities. Much as the way in games of chance, heads and tails tend to even out, so cleverness and dullness cancel and correct each other. Perhaps the rude poem of El Cid is the counterweight demanded by a single epithet of the Eclogues or a maxim from Heraclitus.
The most fleeting thought obeys an invisible plan, and may crown, or inaugurate, a secret design. I know of men who have done evil in order that good may come of it in future centuries, or may already have come of it in centuries past... Viewed in that way, all our acts are just, though also unimportant. There are no spiritual or intellectual merits. Homer composed the Odyssey; given infinite time, with infinite circumstances and changes, it is impossible that the Odyssey should not be composed at least once. No one is someone; a single immortal man is all men. Like Cornelius Agrippa, I am god, hero, philosopher, demon, and world--which is a long-winded way of saying that I am not.
