  He pondered the matter. Now certainly he would have no objection to eating with an Earthman, or even bunking with one in case of need—assuming the Earthman were reasonably clean, and healthy. In fact, he would in all ways treat him as he would treat anyone else, he thought. Yet there was no denying that he would always be conscious of the fact that an Earthman was an Earthman. He couldn't help that. That was the result of a childhood immersed in an atmosphere of bigotry so complete that it was almost invisible, so entire that you accepted its axioms as second nature. Then you left it and saw it for what it was when you looked back.
  But here was his chance to test himself. He was in a plane with only Earthmen about him, and he felt perfectly natural, almost. Well, just a little self-conscious.
  Arvardan looked about at the undistinguished and normal faces of his fellow passengers. They were supposed to be different, these Earthmen, but could he have told these from ordinary men if he had met them casually in a crowd? He didn't think so. The women weren't bad-looking... His brows knit. Of course even tolerance must draw the line somewhere. Intermarriage, for instance, was quite unthinkable.
  The plane itself was, in his eyes, a small affair of imperfect construction. It was, of course, atomic-powered, but the application of the principle was far from efficient. For one thing, the power unit was not well shielded. Then it occurred to Arvardan that the presence of stray gamma rays and a high neutron density in the atmosphere might well strike Earthmen as less important than it might strike others.
  Then the view caught his eyes. From the dark wine-purple of the extreme stratosphere, Earth presented a fabulous appearance. Beneath him the vast and misted land areas in sight (obscured here and there by the patches of sun-bright clouds) showed a desert orange. Behind them, slowly receding from the fleeing stratoliner, was the soft and fuzzy night line, within whose dark shadow there was the sparking of the radioactive areas.

  Not that he was eager to see Chica, he told himself, but the Synapsifier thing could be important, and there was no use being on Earth if he didn't take advantage of it. He certainly never intended to return once he left.
  And then he sat bolt upright—or tried to, struggling bitterly against the forces of inertia that were compressing him down into his seat as the Earth still sank away and the blue of the sky was deepened into a rich purple.
