Those scientists who attributed mental deterioration to the increase of cosmic rays affirmed that if the race had discovered science many centuries earlier, when it had still before it the period of greatest vitality, all would have been well. It would soon have mastered the social problems which industrial civilization entails. It would have created not merely a "mediaeval" but a highly mechanized Utopia. It would almost certainly have discovered how to cope with the excess of cosmic rays and prevent deterioration. But science had come too late. Bvalltu, on the other hand, suspected that deterioration was due to some factor in human nature itself. He was inclined to believe that it was a consequence of civilization, that in changing the whole environment of the human species, seemingly for the better, science had unwittingly brought about a state of affairs hostile to spiritual vigor. He did not pretend to know whether the disaster was caused by the increase of artificial food, or the increased nervous strain of modern conditions, or interference with natural selection, or the softer upbringing of children, or to some other cause. Perhaps it should be attributed to none of these comparatively recent influences; for evidence did suggest that deterioration had set in at the very beginning of the scientific age, if not even earlier. It might be that some mysterious factor in the conditions of the golden age itself had started the rot. It might even be, he suggested, that genuine community generated its own poison, that the young human being, brought up in a perfected society, in a veritable "city of God" on earth, must inevitably revolt toward moral and intellectual laziness, toward romantic individualism and sheer devilment; and that once this disposition had taken root, science and a mechanized civilization had augmented the spiritual decay.
Shortly before I left the Other Earth a geologist discovered a fossil diagram of a very complicated radio set. It appeared to be a lithographic plate which had been made some ten million years earlier. The highly developed society which produced it had left no other trace. This find was a shock to the intelligent world; but the comforting view was spread abroad that some non-human and less hardy species had long ago attained a brief flicker of civilization. It was agreed that man, once he had reached such a height of culture, would never have fallen from it.
In Bvalltu's view man had climbed approximately to the same height time after time, only to be undone by some hidden consequence of his own achievement.
When Bvalltu propounded this theory, among the ruins of Us native city, I suggested that some time, if not this time, man would successfully pass this critical point in his career. Bvalitu then spoke of another matter which seemed to indicate that we were witnessing the final act of this long-drawn-out and repetitive drama. It was known to scientists that, owing to the weak gravitational hold of their world, the atmosphere, already scant, was steadily deceasing. Sooner or later humanity would have to face the problem of stopping this constant leakage of precious oxygen. Hitherto life had successfully adapted itself to the progressive rarefaction of atmosphere, but the human physique had already reached the limit of adaptability in this respect. If the loss were not soon checked, the race would inevitably decline. The only hope was that some means to deal with the atmospheric problem would be discovered before the onset of the next age of barbarism. There had only been a slight possibility that this would be achieved. This slender hope the war had destroyed by setting the clock of scientific research back for a century just at the time when human nature itself was deteriorating and might never again be able to tackle so difficult a problem.
The thought of the disaster which almost certainly lay in wait for the Other Men threw me into a horror of doubt about the universe in which such a thing could happen. That a whole world of intelligent beings could be destroyed was not an unfamiliar idea to me; but there is a great difference between an abstract possibility and a concrete and inescapable danger. On my native planet, whenever I had been dismayed by the suffering and the futility of individuals, I had taken comfort in the thought that at least the massed effect of all our blind striving must be the slow but glorious awakening of the human spirit. This hope, this certainty, had been the one sure consolation. But now I saw that there was no guarantee of any such triumph. It seemed that the universe, or the maker of the universe, must be indifferent to the fate of worlds. That there should be endless struggle and suffering and waste must of'course be accepted; and gladly, for these were the very soil in which the spirit grew. But that all struggle should be finally, absolutely vain, that a whole world of sensitive spirits fail and die, must be sheer evil. In my horror it seemed to me that Hate must be the Star Maker.
Not so to Bvalitu. "Even if the powers destroy us," he said, "who are we, to condemn them? As well might a fleeting word judge the speaker that forms it. Perhaps they use us for their own hihg ends, use our strength and our weakness, our joy and our pain, in some theme inconceivable to us, and excellent." But I protested, "What theme could justify such waste, such futility? And how can we help judging; and how otherwise can we judge than by the light of our own hearts, by which we judge ourselves? It would be base to praise the Star Maker, knowing that he was too insensitive to care about the fate of his worlds." Bvalitu was silent in his mind for a moment. Then he looked up, searching among the smoke-clouds for a daytime star. And then he said to me in his mind, "If he saved all the worlds, but tormented just one man, would you forgive him? Or if he was a little harsh only to one stupid child? What has our pain to do with it, or our failure? Star Maker! It is a good word, though we can have no notion of its meaning. Oh, Star Maker, even if you destroy me, I must praise you. Even if you torture my dearest. Even if you torment and waste all your lovely worlds, the little figments of your imagination, yet I must praise you. For if you do so, it must be right. In me it would be wrong, but in you it must be right."
He looked down once more upon the ruined city, then continued, "And if after all there is no Star Maker, if the great company of galaxies leapt into being of their own accord, and even if this little nasty world of ours is the only habitation of the spirit anywhere among the stars, and this world doomed, even so, even so, I must praise. But if there is no Star Maker, what can it be that I praise? I do not know. I will call it only the sharp tang and savor of existence. But to call it this is to say little."
CHAPTER IV
I TRAVEL AGAIN
I MUST have spent several years on the Other Earth, a period far longer than I intended when I first encountered one of its peasants trudging through the fields. Often I longed to be at home again. I used to wonder with painful anxiety how those dear to me were faring, and what changes I should discover if I were ever to return. It was surprising to me that in spite of my novel and crowded experiences on the Other Earth thoughts of home should continue to be so insistent. It seemed but a moment since I was sitting on the hill looking at the lights of our suburb. Yet several years had passed. The children would be altered almost beyond recognition. Their mother? How would she have fared?
Bvalltu was partly responsible for my long spell on the Other Earth. He would not hear of my leaving till we had each attained a real understanding of the other's world. I constantly stimulated his imagination to picture as clearly as possible the life of my own planet, and he had discovered in it much the same medley of the splendid and the ironical as I had discovered in his. In fact he was far from agreeing with me that his world was on the whole the more grotesque.
