And perhaps there was still another planet, where we would all be born a third time with the experience of our first two lives.

Several days later, he was struck by another thought, which I record here as an addendum to the preceding chapter: Somewhere out in space there was a planet where all people would be born again. They would be fully aware of the life they had spent on earth and of all the experience they had amassed here.

And perhaps there were yet more and more planets, where mankind would be born one degree (one life) more mature.

Only from the perspective of such a utopia is it possible to use the concepts of pessimism and optimism with full justification: an optimist is someone who thinks that on planet number five the history of mankind will be less bloody. A pessimist is one who thinks otherwise.

Of course we here on earth (planet number one, the planet of inexperience) can only fabricate vague fantasies of what will happen to man on those other planets. Will he be wiser? Is maturity within man's power? Can he attain it through repetition?

That was Tomas's version of eternal return.
