Demerzel frowned slightly, but only very slightly, for one does not frown in the Imperial presence. “The Minister of Science, Sire, should have spoken of this man to me as Chief of Staff. If you are to be bombarded from every side-”

Cleon raised his hand and Demerzel stopped at once. “Please, Demerzel, one can’t stand on formality at all times. When I passed the Minister at last night’s reception and exchanged a few words with him, he bubbled over. I could not refuse to listen and I was glad I had, for it was interesting.”

“In what way interesting, Sire?”

“Well, these are not the old days when science and mathematics were all the rage. That sort of thing seems to have died down somehow, perhaps because all the discoveries have been made, don’t you think? Apparently, however, interesting things can still happen. At least I was told it was interesting.”

“By the Minister of Science, Sire?”

“Yes. He said that this Hari Seldon had attended a convention of mathematicians held here in Trantor-they do this every ten years, for some reason-and he said that he had proved that one could foretell the future mathematically.”

Demerzel permitted himself a small smile. “Either the Minister of Science, a man of little acumen, is mistaken or the mathematician is. Surely, the matter of foretelling the future is a children’s dream of magic.”

“Is it, Demerzel? People believe in such things.”

“People believe in many things, Sire.”

“But they believe in such things. Therefore, it doesn’t matter whether the forecast of the future is true or not. If a mathematician should predict a long and happy reign for me, a time of peace and prosperity for the Empire-Eh, would that not be well?”

“It would be pleasant to hear, certainly, but what would it accomplish, Sire?”

“But surely if people believe this, they would act on that belief. Many a prophecy, by the mere force of its being believed, is transmuted to fact. These are ‘self-fulfilling prophecies.’ Indeed, now that I think of it, it was you who once explained this to me.”
