And then — U. S. Robots has interstellar travel, and humanity has the opportunity for galactic empire. - Isaac Asimov

In part because of a man named Elijah Baley, an Earthman."
Pelorat put in excitedly, "He is the culture-hero I mentioned some time ago, Golan."
"A culture-hero, sir?"
"What Dr. Pelorat means," said Trevize, "is that he is a person to whom much was attributed, and who may have been an amalgamation of many men in actual history, or who may be an invented person altogether."
Daneel considered for a moment, and then said, quite calmly, "That is not so, sirs. Elijah Baley was a real man and he was one man. I do not know what your legends say of him, but in actual history, the Galaxy might never have been settled without him.

"But you haven't tried. You haven't tried once. First you refused to admit that there was a menace at all! Then you reposed an absolutely blind faith in the Emperor! Now you've shifted it to Hari Seldon. Throughout you have invariably relied on authority or on the past — never on yourselves."

His fists balled spasmodically. "It amounts to a diseased attitude — a conditioned reflex that shunts aside the independence of your minds whenever it is a question of opposing authority. There seems no doubt ever in your minds that the Emperor is more powerful than you are, or Hari Seldon Wiser. And that's wrong don't you see?"

For some reason, no one cared to answer him.

Hardin continued: "It isn't just you. It's the whole Galaxy. Pirenne heard Lord Dorwin's idea of scientific research. Lord Dorwin thought the way to be a good archaeologist was to read all the books on the subject — written by men who were dead for centuries. He thought that the way to solve archaeological puzzles was to weight the opposing authorities. And Pirenne listened and made no objections. Don't you see that there's something wrong with that?"

Again the note of near-pleading in his voice.

Again no answer. He went on: "And you men and half of Terminus as well are just as bad.. We sit here, considering the Encyclopedia the all-in-all. We consider the greatest end of science is the classification of past data. It is important, but is there no further work to be done? We're receding and forgetting, don't you see? Here in the Periphery they've lost nuclear power. In Gamma Andromeda, a power plant has undergone meltdown because of poor repairs, and the Chancellor of the Empire complains that nuclear technicians are scarce. And the solution? To train new ones? Never! Instead they're to restrict nuclear power."

And for the third time: "Don't you see? It's galaxy-wide. It's a worship of the past. It's a deterioration — a stagnation!"

To Mankind
And the hope that the war against folly
may someday be won after all.
