Programmer Shuman did not try to hurry matters. Loesser was conservative, very conservative, and liked to deal with computers as his father and grandfather had.

Still, he controlled the West European computer combine, and if he could be persuaded to join Project Number in full enthusiasm, a great deal would be accomplished.

But Loesser was holding back. He said, “I’m not sure I like the idea of relaxing our hold on computers. The human mind is a capricious thing. The computer will give the same answer to the same problem each time. What guarantee have we that the human mind will do the same?”

“The human mind, Computer Loesser, only manipulates facts. It doesn’t matter whether the human mind or a machine does it. They are just tools.”

“Yes, yes. I’ve gone over your ingenious demonstration that the mind can duplicate the computer but it seems to me a little in the air. I’ll grant the theory but what reason have we for thinking that theory can be converted to practice?”

“I think we have reason, sir. After all, computers have not always existed. The cave men with their triremes, stone axes, and railroads had no computers.”

“And possibly they did not compute.”

“You know better than that. Even the building of a railroad or a ziggurat called for some computing, and that must have been without computers as we know them.”

“Do you suggest they computed in the fashion you demonstrate?”

“Probably not. After all, this method—we call it ‘graphitics,’ by the way, from the old European word ‘graph’ meaning ‘to write’—is developed from the computers themselves so it cannot have antedated them. Still, the cave men must have had some method, eh?”

“Lost arts! If you’re going to talk about lost arts—”

“No, no. I’m not a lost art enthusiast, though I don’t say there may not be some. After all, man was eating grain before hydroponics, and if the primitives ate grain, they must have grown it in soil. What else could they have done?”
