 What drove Stinson to decide to stay in the end?
Stinson lay still in the sand where he fell, gloating over the success of his arrival. He touched the pencil-line scar behind his ear where the cylinder was buried, marveling at the power stored there, power to fling him from earth to this fourth planet of the Centaurian system in an instant. A gray, funnel-shaped cloud of dust stood off to his left. Weather control made cyclones and other climatic phenomena on earth practically non-existent. Dark clouds capped one peak of the mountains on his left. He was here and Earth was somewhere up there. The sun shone obliquely, throwing Stinson's shadow upon the sand. Again Stinson felt the urge to run, or to use the cylinder to project himself somewhere else, but he said, "No!" very firmly to himself. He was here to investigate, to determine if this planet was capable of supporting life. There was no core, no central place you could point to and say, here is the brain, or the nervous system. But then, how could a group of loosely spaced grains of sand possibly have a nervous system? When it changed to a cube he drew a square, a circle for a sphere, and so on. He became so absorbed in doing this that he failed to notice how the wind devil drew closer and closer, but when he inhaled the first grains of sand, the realization of what was happening dawned with a flash of fear. He decided it would not be just, to give up so easily. He left the chains by his own method of travel, and reappeared behind the two men. Still angered, Stinson grasped it firmly, with half a notion to break it over his head. But up to now the tube and the chain was the only evidence of an advanced technology, unless the ancient inscriptions in the stone wall of the pool, and the statues lining the wall were evidences. Incongruously, he thought of Benjamin back on earth, and all the others with cylinders, who might be fighting for their lives at this moment. You want to live here, on this planet." It is impossible to move a physical body from one place to another by a mere thought and a tiny instrument, yet you have done so. Stinson cried angrily, "You tried to kill me!" That is, they did not make it directly. These are the undesirables, the incorrigibles, the nonconformists from the sixth planet.
