The gray-muzzled head sank back wearily. A scuffling sound drew Phil's dazed eyes and he turned back in time to see Tim sit up again briskly, ignoring the old dog.
"I hate that mangled speech, don't you, Uncle Phil? I'll still call you that, if you don't mind. You're still as much my uncle as you ever were, and I'm the only Tim you've known." He watched Phil anxiously. "Knocks the wind out of you, doesn't it? But ordinary speech is painfully limited to begin with, without trying to force it from poor old Homer." He chattered on nervously, giving Phil time to collect himself. "You see, Timmy is as mindless now as when he was born, three years before 'my' ship crashed in the swamp over there. Look back through your newspaper files and you'll find a brief mention of a mysterious explosion reported during a night of heavy rain. That was us." He wet his lips, watching the silent white face. "Look, I had nothing at all to do with Timmy being born an imbecile. He's like a car that functions well enough if a driver takes over the physical controls that Timmy is incapable of handling for himself. Lacking a driver, the controls and the car stand idle. It is only the body that I manipulate, not the dormant, disconnected mind. For myself, although I can't help identifying myself emotionally and subjectively as the Challon, Objective reason assures me that I am Homer, with a complete but false set of memories and an artificially stimulated intelligence.
"As the Challon, I realized that the embryo Homer was of low actual intelligence, but high potential intelligence. The dangerous peculiarity of this planet is that several of the higher species have no known or recognized function for the most important portion of their brain. It lies fallow, unused, blocked off much as Timmy's whole mind is blocked off from his service. In eight years I have done no more than form the mere skeleton of a theory to account for that, but the means of correction was obvious from the start. Like the appendix that floats free at one end and serves no known purpose, the brain has an incomplete neural path of an unusual nature that has effectively camouflaged its true purpose. The intended function of the connection was the energizing of that prime center which you have not yet discovered and without which you differ from Timmy only in degree, for you cannot realize more than a fragment of your incredible potential.
"The same condition exists among the higher mammals. Releasing Homer's blocked potential placed at his service the intellectual capacity of a very clever human—according to your false standards—but not of a human genius. If I had not imposed my ego on him ... you see, I cannot help thinking of myself as the Challon, although I know I am Homer ... if I had not robbed Homer of his identity and self-will, of his right to possess and control himself, he would have developed personality, characteristics and aptitudes of his own, appropriate to a canine of high intelligence. As it is, there are false memories of aptitudes Homer never had nor could have. Physical limitations alone make some of them impossible. How could a dog tinker with machinery, for example? Yet I 'remember' working on machines of my own design. Homer's mind, in other words, remembers as first-person data experiences it never had.
"In actual fact, 'I' who speak to you now am no more than the record contained in a book. In terms of personality, Homer is the hidden structure giving strength and substance to a false facade. 'I' am the false facade, faithfully copied from another structure. 'I' am a superimposure of ephemeral data, governing its own employment by a mind that has been restricted from developing its own data. The 'I' that speaks to you has no real existence, though its pattern is being subtly and continuously altered by that which it cloaks. If you put a drop of intense stain and a drop of powerful scent into a large tank of distilled water, you change the superficial character of the water, make it seem to be other than what it is. But it remains essentially a tank full of water, now containing an obtrusive trifle of alien matter in addition to the hydrogen and oxygen that decide its most significant properties. That is what the Challon did to Homer—he released the potential, then accidentally but indelibly stained it with his own personality.
"To me, now, it merely seems as though I first suffered death and then an unwelcome resurrection, awakening in despair to find myself usurping the helpless body of an almost new-born animal. Nothing physical or spiritual of the Challon survived, but the embryo mind had been fed a ready-made identity and so believed that it had already existed as a Challon before re-birth as a dog. Its brain received instantly all 'my' training, so that it became at once 'mature.' What I have endured in these eight years—the isolation of mind and inadequacy of body—have been a blunderer's reward visited upon his victim as a further injury. Now that Homer lies near death—and 'I' with him, of course—I welcome 'our' approaching release from an unhappy situation.
"Wait—let me finish. Your main concern is what will happen to Timmy when 'we' die, but it will be simpler to understand if I explain as much as I can first. Finding myself to be a rational mind in the helpless, immature body of an animal, I thought I was isolated forever. In choosing the embryo to begin with, I was driven by the need for haste and had not understood the limitations of a canine in a human world, nor would I have had any alternative if I had fully understood. When it was too late, it was not difficult to predict my future. I had no means of communicating with the dominant species, Man. In time, if I survived the hazards a puppy is exposed to, I could reveal my unusual intelligence—could even learn to communicate in some hopelessly labored manner. By using my store of inherited knowledge I could, if anyone would take a dog seriously, advance your science. But I could do nothing toward my main goals without exposing myself as an imitation Challon, and that I must never do lest I loose terrible consequences.
"I knew that the life span of my new body was pitifully short. The female had suffered repeated convulsions that affected the formation of the embryos and we were an ugly litter of little mongrels, doomed by our physical imperfections to a shorter-than-normal life if we were allowed to live and exposed to early drowning if we could not quickly charm ourselves into a home.
