For obvious reasons, I’ve always managed to do that. For reasons that you will see, I’ve never wanted power, nor have I ever—after the first few hundred years—let people suspect that I was different from them. I even spend a few hours each night lying thinking, pretending to sleep.

But none of that is important, any more than I am important. I tell it to you only so you will understand how I know the thing that I am about to tell you.

And when I tell you, it is not because I’m trying to sell you anything. It’s something you can’t change if you want to, and—when you understand it—you won’t want to.

I’m not trying to influence you or to lead you. In four thousand lifetimes I’ve been almost everything—except a leader. I’ve avoided that. Oh, often enough I have been a god among savages, but that was because I had to be one in order to survive. I used the powers they thought were magic only to keep a degree of order, never to lead them, never to hold them back. If I taught them to use the bow and arrow, it was because game was scarce and we were starving and my survival depended upon theirs. Seeing that the pattern was necessary, I have never disturbed it.

What. I tell you now will not disturb the pattern.

It is this: The human race is the only immortal organism in the universe.

There have been other races, and there are other races throughout the universe, but they have died away or they will die. We charted them once, a hundred thousand years ago, with an instrument that detected the presence of thought, the presence of intelligence, however alien and at whatever distance—and gave us a measure of that mind and its qualities. And fifty thousand years later that instrument was rediscovered. There were about as many races as before but only eight of them were ones that had been there fifty thousand years ago and each of those eight was dying, senescent. They had passed the peak of their powers and they were dying.

They had reached the limit of their capabilities—and there is always a limit—and they had no choice but to die. Life is dynamic; it can never be static—at however high or low a level—and survive.

That is what I am trying to tell you, so that you will never again be afraid. Only a race that destroys itself and its progress periodically, that goes back to its beginning, can survive more than, say, sixty thousand years of intelligent life.

In all the universe only the human race has ever reached a high level of intelligence without reaching a high level of sanity. We are unique. We are already at least five times as old as any other race has ever been and it is because we are not sane. And man has, at times, had glimmerings of the fact that insanity is divine. But only at high levels of culture does he realize that he is collectively insane, that fight against it as he will he will always destroy himself—and rise anew out of the ashes.
