"The instructor replied that I'd been given an answer to my question, that 'the first lesson you must learn if you wish to acquire our pace in science is to recognize that we have been along the path ahead of you. We know which are the possibilities that are worthwhile to develop. We have gained our speed by learning to bypass every avenue but the main one, and not get lost in tempting side roads.'

"He said that we've got to learn to trust them and take their word as to which is the correct and profitable field of research, that 'we will show you where to go, as we agreed to do. If you are not willing to accept our leadership in this respect our agreement means nothing.' Wouldn't that be a magnificent way to make scientific progress!"

The mathematician shifted in his chair as if trying to control an internal fury that would not be capped. He held out his hand abruptly. "I'll take that cigar after all, if you don't mind, Hockley."

With savage energy he chewed the end and ignited the cigar, then blew a mammoth cloud of smoke ceilingward. "I think the trouble must be in our lecturer," he said. "He's crazy. He couldn't possibly represent the conventional attitude of the Rykes. They promised to give answers to our problems—and this is the kind of nonsense I get. I'm going to see somebody higher up and find out why we can't have a lecturer who knows what he's talking about. Or maybe you or Markham would rather take it up—through official channels, as it were?"

"The Ryke was correct," said Hockley. "He did give you an answer."

"He could answer all our questions that way!"

"You're perfectly right," said Hockley soberly. "He could do exactly that."

"They won't of course," said Silvers, defensively. "Even if this particular character isn't just playing the screwball, my question is just a special case. It's just one particular thing they consider to be valueless. Perhaps in the end I'll find they're right—but I'm going to develop a solution to these Equations if it takes the rest of my life!

"After all, they admit they have no solution, that they have not bothered to go down this particular side path, as they put it. If we don't go down it how can we ever know whether it's worthwhile or not? How can the Rykes know what they may have missed by not doing so?"

"I can't answer that," said Hockley. "For us or for them, I know of no other way to predict the outcome of a specific line of research except to carry it through and find out what lies at the end of the road."
