It appears that something similar has happened, which our correspondence has brought out. Young Schweeringen predicted what a computer would report from unknown numerals and instructions. In order for the computer to match his predictions, it had to err. It did. Therefore one reasons that he did not predict what the computer would produce. The computer produced what he predicted. In effect, what appeared to be foreknowledge was psychokinesis--the same phenomenon as the movement of crumbs of cheese by my rat. One may strongly suspect that when young Herr Schweeringen knew in advance what the computer would say, he actually knew in advance what he could make it say. It is possible that one can consciously know in advance only what one can unconsciously bring about. If one can bring about only minor happenings, one can never predict great ones. This is my answer to your question. I would like very much to know what the elder Schweeringen predicted that The Leader would accomplish! My she-dog has died. We had a new attendant in the laboratory. He fed her to excess. She died of it. (Et cetera.) * * * * * Letter from Professor Albrecht Aigen to Dr. Thurn. My dear Karl: I have resolved to dismiss psionic ability from my investigation into The Leader's rise to power. This much I will concede: The Leader could enslave--englamour--enchant anyone who met him personally. He did. To a lesser degree, this irresistible persuasiveness is a characteristic of many successful swindlers. But he could not have englamoured the whole nation. He did not meet enough persons personally to make his regime possible, unless he could cause other persons to apply their own magnetism to further his ambitions, and they others and others and so on--like an endless series of magnets magnetized originally from one. This is not possible. I restrict myself to normal, plausible hypotheses--of which so far I have no faintest trace. You agree with me, do you not--that it was impossible for The Leader to weave a web of enchantment over the whole nation by his own psi energies controlling the psi energies of others? I would welcome your assurance that it could not be. * * * * * Letter from Professor Albrecht Aigen to Dr. Karl Thurn. My dear Karl: Did you receive my last letter? I am anxious to have your assurance that it was impossible that The Leader could englamour the whole nation by his psionic gifts. * * * * * Telegram, Dr. Albrecht Aigen to Dr. Karl Thurn. Karl, as you are my friend, answer me! * * * * * Letter, Dr. Karl Thurn to Professor Albrecht Aigen. ... But what have you discovered, my friend, that you are afraid to face? * * * * * Letter.
