"You do not understand," he said. "It is too big for you to grasp, but I will try to explain it. Barsoom, the moons, the sun, the stars, were created for a single purpose. From the beginning of time Nature has labored arduously toward the consummation of this purpose. At the very beginning things existed with life, but with no brain. Gradually rudimentary nervous systems and minute brains evolved. Evolution proceeded. The brains became larger and more powerful. In us you see the highest development; but there are those of us who believe that there is yet another step-that some time in the far future our race shall develop into the super-thing-just brain. The incubus of legs and chelae and vital organs will be removed. The future kaldane will be nothing but a great brain. Deaf, dumb, and blind it will lie sealed in its buried vault far beneath the surface of Barsoom-just a great, wonderful, beautiful brain with nothing to distract it from eternal thought."
"You mean it will just lie there and think?" cried Tara of Helium.
"Just that!" he exclaimed. "Could aught be more wonderful?"
"Yes," replied the girl, "I can think of a number of things that would be infinitely more wonderful."
