"Between certain minds, perhaps yes; perhaps between the minds of separated twins, or the minds of people so closely associated they can guess accurately what each other thinks. But for one deliberately to transmit thought—well, I've always believed that whoever claimed to do it was a charlatan, a blasted liar!" "How," said Jan Rober softly, "do you know what you have always believed when you can't remember so much as one yesterday?" "I don't know," I said desperately. "That thought came out of my very being, so I know it must be true, whoever I may have been yesterday. But remembering something out of the years since one was born, and something out of a pre-existence, are horses of different shades of falsehood. Anghor hints of the Creative Fiat, allegedly an attribute of the Creator only, and of unplumbed depths of power in human thought. I don't believe I am contributing anything." Doctor A raised his head, and his eyes flashed. "You did design, while you were away your Televisor of Speech-Thought," he said sternly. "And it is so revolutionary that we're not going to trust it out of the Lab. With the world equipped with it, nobody could ever get away with a lie. I'm not sure the world is ready for such a dose of truth. "But you belittle the power of human thought. Let me ask you some questions. Which was greater, the unplumbed thoughts of Thomas Alva Edison, or the selected thoughts which resulted in his countless inventions? And which is greater, more important, the invention, or the thought which produced it? And can you insist, after giving it some thought, that anything man uses is not a manifestation of thought, his own or another's? "Thoughts direct the engineers who plan the Grand Coulee Dam, so that it is set down on paper to proper scale. That design is thought made manifest. Other engineers, working with the design, issue orders, which they have carefully thought out, to many junior foremen, who pass them on. Laborers, carpenters, cementers, plasterers, stone-and-sand workers, receive the thought-out orders, turn them over in their minds, absorb them, transmit their own personal, individual orders to their own hands and feet. The hands and feet, directed by thought, perform the myriad details of labor which result, in time, in the Grand Coulee Dam, greatest work of man existing on earth today save one—the Great Wall of China, also the result of thought." I reeled mentally, trying to absorb this. It sounded
