physically to Arisia. It is, you will observe, in an insulated container, and does not glow. Touch its surface, but lightly and very fleetingly, for the contact will be painful."
Samms' finger-tip barely touched one dull, gray, lifeless jewel: his whole arm jerked away uncontrollably as there swept through his whole being the intimation of an agony more poignant by far than any he had ever known.
"Why—it's alive!" he gasped.
"No, it is not really alive, as you understand the term ..." Mentor paused, as though seeking a way to describe to the Tellurian a thing which was to him starkly incomprehensible. "It is, however, endowed with what you might call a sort of pseudo-life; by virtue of which it gives off its characteristic radiation while, and only while, it is in physical circuit with the living entity—the ego, let us say—with whom it is in exact resonance. Glowing, the Lens is perfectly harmless; it is complete—saturated—satiated—fulfilled. In the dark condition it is, as you have learned, dangerous in the extreme. It is then incomplete—unfulfilled—frustrated—you might say seeking or yearning or demanding. In that condition its pseudo-life interferes so strongly with any life to which it is not attuned that that life, in a space of seconds, is forced out of this plane or cycle of existence."
"Then I—I alone—of all the entities in existence, can wear this particular Lens?" Samms licked his lips and stared at it, glowing so satisfyingly and contentedly upon his wrist. "But when I die, will it be a perpetual menace?"
"By no means. A Lens cannot be brought into being except to match some one living personality; a short time after you pass into the next cycle your Lens will disintegrate."
"Wonderful!" Samms breathed, in awe. "But there's one thing ... these things are ... priceless, and there will be millions of them to make ... and you don't...."
"What will we get out of it, you mean?" The Arisian seemed to smile.
"Exactly." Samms blushed, but held his ground. "Nobody does anything for nothing. Altruism is beautiful in theory, but it has never been known to work in practice. I will pay a tremendous price—any price within reason or possibility—for the Lens; but I will have to know what that price is to be."
"It will be heavier than you think, or can at present realize; although not in the sense you fear." Mentor's thought was solemnity itself. "Whoever wears the Lens of Arisia will carry a load that no weaker mind could bear. The load of authority; of responsibility; of knowledge that would wreck completely any mind of lesser strength. Altruism? No. Nor is it a case of good against evil, as you so firmly believe. Your mental picture of glaring white and of unrelieved black is not a true picture. Neither absolute evil nor absolute good do or can exist."
"But that would make it still worse!" Samms protested. "In that case, I can't see any reason at all for your exerting yourselves—putting yourselves out—for us."
"There is, however, reason enough; although I am not sure that I can make it as clear to you as I would wish. There are in fact three reasons; any one of which would justify us in exerting—would compel us to exert—the trivial effort involved in the furnishing of Lenses to your Galactic Patrol. First, there is nothing either intrinsically right or intrinsically wrong about liberty or slavery, democracy or autocracy, freedom of action or complete regimentation. It seems to us, however, that the greatest measure of happiness and of well-being for the greatest number of entities, and therefore the optimum advancement toward whatever sublime Goal it is toward which this cycle of existence is trending in the vast and unknowable Scheme of Things, is to be obtained by securing for each and every individual the greatest amount of mental and physical freedom compatible with the public welfare. We of Arisia are only a small part of this cycle; and, as goes the whole, so goes in greater or lesser degree each of the parts. Is it impossible for you, a fellow citizen of this cycle-universe, to believe that such fulfillment alone would be ample compensation for a much greater effort?"
"I never thought of it in that light...." It was hard for Samms to grasp the concept; he never did understand it thoroughly. "I begin to see, I think ... at least, I believe you."
"Second, we have a more specific obligation in that the life of many, many worlds has sprung from Arisian seed. Thus, in loco parentis, we would be derelict indeed if we refused to act. And third, you yourself spend highly valuable time and much effort in playing chess. Why do you do it? What do you get out of it?"
"Why, I ... uh ... mental exercise, I suppose ... I like it!"
"Just so. And I am sure that one of your very early philosophers came to the conclusion that a fully competent mind, from a study of one fact or artifact belonging to any given universe, could construct or visualize that universe, from the instant of its creation to its ultimate end?"
"Yes. At least, I have heard the proposition stated, but I have never believed it possible."
"It is not possible simply because no fully competent mind ever has existed or ever will exist. A mind can become fully competent only by the acquisition of infinite knowledge, which would require infinite time as well as infinite capacity. Our equivalent of your chess, however, is what we call the 'Visualization of the Cosmic All'. In my visualization a descendant of yours named Clarrissa MacDougall will, in a store called Brenleer's upon the planet ... but no, let us consider a thing nearer at hand and concerning you personally, so that its accuracy will be subject to check. Where you will be and exactly what you will be doing, at some definite time in the future. Five years, let us say?"
"Go ahead. If you can do that you're good."
"Five Tellurian calendar years then, from the instant of your passing through the screen of 'The Hill' on this present journey, you will be ... allow me, please, a moment of thought ... you will be in a barber shop not yet built; the address of which is to be fifteen hundred fifteen Twelfth Avenue, Spokane, Washington, North America, Tellus. The barber's name will be Antonio Carbonero and he will be left-handed. He will be engaged in cutting your hair. Or rather, the actual cutting will have been done and he will be shaving, with a razor trade-marked 'Jensen-King-Byrd', the short hairs in front of your left ear. A comparatively small, quadrupedal, grayish-striped entity, of the race called 'cat'—a young cat, this one will be, and called Thomas, although actually of the female sex—will jump into your lap, addressing you pleasantly in a language with which you yourself are only partially familiar. You call it mewing and purring, I believe?"
"Yes," the flabbergasted Samms managed to say. "Cats do purr—especially kittens."
"Ah—very good. Never having met a cat personally, I am gratified at your corroboration of my visualization. This female youth erroneously called Thomas, somewhat careless in computing the elements of her trajectory, will jostle slightly the barber's elbow with her tail; thus causing him to make a slight incision, approximately three millimeters long, parallel to and just above your left cheek-bone. At the precise moment in question, the barber will be applying a styptic pencil to this insignificant wound. This forecast is, I trust, sufficiently detailed so that you will have no difficulty in checking its accuracy or its lack thereof?"
"Detailed! Accuracy!" Samms could scarcely think. "But listen—not that I want to cross you up deliberately, but I'll tell you now that a man doesn't like to get sliced by a barber, even such a little nick as that. I'll remember that address—and the cat—and I'll never go into the place!"
"Every event does affect the succession of events," Mentor acknowledged, equably enough. "Except for this interview, you would have been in New Orleans at that time, instead of in Spokane. I have considered every pertinent factor. You will be a busy man. Hence, while you will think of this matter frequently and seriously during the near future, you will have forgotten it in less than five years. You will remember it only at the touch of the astringent, whereupon you will give voice to certain self-derogatory and profane remarks."
"I ought to," Samms grinned; a not-too-pleasant grin. He had been appalled by the quality of mind able to do what Mentor had just done; he was now more than appalled by the Arisian's calm certainty that what he had foretold in such detail would in every detail come to pass. "If, after all this Spokane—let a tiger-striped kitten jump into my lap—let a left-handed Tony Carbonero nick me—uh-uh, Mentor,
