"I suppose it's the time-scale and the value-scale that are so hard for us to accept," he said softly. "Much more, even, than the size-scale. The thought that there are creatures in the Universe to whom the whole career of Man--in fact, the whole career of life--is no more than a few thousand or hundred thousand years. And to whom Man is no more than a minor stage property--a trifling part of a clever job of camouflage." This time he went on, "Fantasy writers have at times hinted all sorts of odd things about the Earth--that it might even be a kind of single living creature, or honeycombed with inhabited caverns, and so on. But I don't know that any of them have ever suggested that the Earth, together with all the planets and moons of the Solar System, might be...." In a whisper, Frieda finished for him, "... a camouflaged fleet of gigantic spherical spaceships." "_Your guess happens to be the precise truth._" At that familiar, yet dreadly unfamiliar voice, all four of them swung toward the inner door. Dotty was standing there, a sleep-stupefied little girl with a blanket caught up around her and dragging behind. Their own daughter. But in her eyes was a look from which they cringed. She said, "I am a creature somewhat older than what your geologists call the Archeozoic Era. I am speaking to you through a number of telepathically sensitive individuals among your kind. In each case my thoughts suit themselves to your level of comprehension. I inhabit the disguised and jetless spaceship which is your Earth." Celeste swayed a step forward. "Baby...." she implored. Dotty went on, without giving her a glance, "It is true that we planted the seeds of life on some of these planets simply as part of our camouflage, just as we gave them a suitable environment for each. And it is true that now we must let most of that life be destroyed. Our hiding place has been discovered, our pursuers are upon us, and we must make one last effort to escape or do battle, since we firmly believe that the principle of mental privacy to which we have devoted our existence is perhaps the greatest good in the whole Universe. "But it is not true that we look with contempt upon you. Our whole race is deeply devoted to life, wherever it may come into being, and it is our rule never to interfere with its development. That was one of the reasons we made life a part of our camouflage--it would make our pursuers reluctant to examine these planets too closely. "Yes, we have always cherished you and watched your evolution with interest from our hidden lairs. We may even unconsciously have shaped your development in certain ways, trying constantly to educate you away from war and finally succeeding--which may have given the betraying clue to our pursuers.
