"Fine. I don't want to come back. And I don't need to change the future, neither. Things may be different, but a smart cookie can always get along. Now, according to the news, you only sent these guys ahead a year. That ain't enough. What's the most you could send me ahead?"
"Theoretically, we could send a subject ahead as much as twenty years, if we could find anyone who would consent to that, and undoubtedly we could learn a great deal more by so doing."
"But you did find out that the boys come through okay?"
"Yes. We sent these two men ahead in 1961. When they returned to awareness, it was 1962. Physically and mentally they were as fit as before."
"Did they know what happened to them?"
"Well, the year had no apparent duration for them, but they had normal speed memories of the intervening year when they returned to awareness. Evidently their fore-memories for the entire year must have been condensed into the brief period they were in the field. From this phenomenon, we derive the term 'sending the subjects ahead' which has so often been misinterpreted. But it's important to note that these condensed fore-memories were not available until twenty-four to forty-eight hours after the events, which means the future cannot be effectively predicted by present techniques."
That sounded like plain English; it sounded as if it meant something, but Slick wasn't quite sure what. He seized on the last remark, which he understood.
"What did you build this gadget for, if you can't tell fortunes with it?" he asked.
"The layman thinks in terms of immediate practical application. But our primary objective was knowledge of the human mind. We confirmed the existence of mental capacities that have been suspected for centuries. We formulated the axiom that awareness is a function of subconscious fore-memories becoming currently available. We experimentally suspended awareness without inducing unconsciousness, by causing the fore-memories to condense. I hope the process will develop into a useful tool for my profession, that we learn how to superimpose conditioning on the blank area to produce rational, socially acceptable action, rather than the literal and irrational compulsion which is a drawback to implanting post-hypnotic commands. But I can't tell you at this point where our research will lead."
