All what's needed to save the Earth is to plant the Seed of the Gates — and Humans'll join the Shadow, escaping outer threats. But the Seed will grow only if a person sincerely wants it. Maybe the world of the Shadow is really good, but Pyotr and his friends can't like it — they were in too unpleasant worlds on their way across planets of the Shadow. "A man can't be allowed to have such a freedom. One can't leave decisions to be made by a handful of garbage on the bottom of the subconsciousness. We 've learned — long ago — to act not as we want but as it's needed, and found our real freedom in it. Even in the inanimous slavery of Geometers there are more gaps for real freedom, than in the Shadow, a world of absolute permissiveness. Because to act exactly as you want is the real slavery." — somewhat debatable thoughts of Pyotr.
