I lost mine and so has Glenna now.
The signature was unmistakably Hurd's but the note made no sense. Hurd's hearing was as sound as Dirrul's. He had never used a mechanical device—how could he have lost it then? So has Glenna—that must be the key. Hurd somehow knew about the vagabond raiding party that had rescued Glenna from the mental hospital. He must have escaped from the Vininese earlier himself. He was probably hiding somewhere in the capital.
Working on this hypothesis Dirrul made a guess that the thing Hurd had lost was his illusion about the Vininese system. The hearing aid symbolized what Hurd had been told about it, as opposed to the reality which he saw with his own eyes.
But such an interpretation didn't ring entirely true. It was too involved for an idea which could have been better expressed in four words—I know the truth. Tossing the note aside Dirrul turned on the water in the shower room and thoughtfully disrobed.
As he threw his tunic aside a violent paralyzing terror seized his mind, making his head sing with a screeching vibration. Blindly he snatched up the tunic in order to stuff the cloth into his mouth so he would not cry out. But as soon as he pressed it against his skin his terror vanished, like a siren suddenly stilled.
The pattern of the real truth fell into place then. Now he understood the power of Vinin. Experimentally he took Sorgel's disk out of his tunic and laid it on a table. As soon as he did so the blinding nameless horror flamed up. When he held the disk again the exhausting emotion vanished.
Looking back Dirrul saw an abundance of evidence that might have given him a clue, had he not spent so much mental effort bolstering his illusion of Vinin. There was the circumstance of his own unrelenting terror when he was without the disk in the ravine—the painful sight of his captors puncturing the prisoners' eardrums—the soundless talk of the vagabonds, like the lip-reading of the deaf—the bleak orderliness of the cheering mobs—and, most obvious of all, the strange transmitters atop the well-guarded stone block-buildings.
It was all there, even to the final cruelty to the children. What was it the Vininese had said? "The adjustment is sometimes very severe but on the whole the casualties are light." And the very young, before they were taken from their parents, didn't need disks because they were in what the Vininese had called "the instinct period."
Dirrul knew what Hurd's drawing meant. Somehow Hurd had lost his hearing, perhaps as a result of the beating the police had given him on Agron. In any case only the deaf could think rationally on Vinin. Hurd was telling Dirrul to shatter his own sense of hearing if he still had the will to think and act for himself. The nightmare Dirrul had witnessed in the ravine was not torture but the bravery of desperate men attempting to rescue rational minds.
The Rational Potential—the gift of the legendary Earthmen! Like the processes of thought itself it could never be wiped out by argument or reason once it was understood. The Earthmen had wasted centuries trying to undo their own evolved rationality before they realized it could not be done. Now, on a higher level in another plane, the Vininese were struggling to submerge the Earthmen's second achievement of the Rational Potential.
