“It is change, continuing change, inevitable change, that is the dominant factor in society today. No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be...  This, in turn, means that our statesmen, our businessmen, our everyman must take on a science fictional way of thinking.”

“Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today, but the core of science fiction -- its essence -- has become crucial to our salvation, if we are to be saved at all.”

“In Hamilton's The Universe Wreckers... it was in that novel that, for the first time, I learned Neptune had a satellite named Triton... It was from The Drums of Tapajos that I first learned there was a Mato Grosso area in the Amazon basin. It was from The Black Star Passes and other stories by John W. Campbell that I first heard of relativity.The pleasure of reading about such things in the dramatic and fascinating form of science fiction gave me a push toward science that was irresistible. It was science fiction that made me want to be a scientist strongly enough to eventually make me one.That is not to say that science fiction stories can be completely trusted as a source of specific knowledge... However, the misguidings of science fiction can be unlearned. Sometimes the unlearning process is not easy, but it is a low price to pay for the gift of fascination over science.”

“And Mallow laughed joyously. "You've missed, Sutt, missed as badly as the Commdor himself. You've missed everything, and understood nothing. The Empire has always been a realm of colossal resources. They've calculated everything in planets, in stellar systems, in whole sectors of the Galaxy. Their generators are gigantic because they thought in gigantic fashion."But we,—we, our little Foundation, our single world almost without metallic resources,—have had to work with brute economy. Our generators have had to be the size of our thumb, because it was all the metal we could afford. We had to develop new techniques and new methods,—techniques and methods the Empire can't follow because they have degenerated past the stage where they can make any vital scientific advance."With all their nuclear shields, large enough to protect a ship, a city, an entire world; hey could never build one to protect a single man. To supply light and heat to a city, they have motors six stories high,—I saw them—where ours could fit into this room. And when I told one of their nuclear specialists that a lead container the size of a walnut contained a nuclear generator, he almost choked with indignation on the spot."Why, they don't even understand their own colossi any longer. The machines work from generation to generation automatically and the caretakers are a hereditary caste who would be helpless if a single D-tube in all that vast structure burnt out."The whole war is a battle between these two systems; between the Empire and the Foundation; between the big and the little. To seize control of a world, they bribe with immense ships that can make war, but lack all economic significance. We, on the other hand, bribe with little things, useless in war, but vital to prosperity and profits."A king, or a Commdor, will take the ships and even make war. Arbitrary rulers throughout history have bartered their subjects' welfare for what they consider honor, and glory, and conquest. But it's still the little things in life that count—and Asper Argo won't stand up against the economic depression that will sweep all Korell in two or three years.”

“Anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that 'my ignorance is just as good as your knowledge.'”

“They won't listen. Do you know why? Because they have certain fixed notions about the past. Any change would be blasphemy in their eyes, even if it were the truth. They don't want the truth; they want their traditions.”

“Surely, if we take on thinking partners––or, at the least, thinking servants––in the form of machines, we will be more comfortable with them, and will relate to them more easily, if they are shaped like humans. It will be easier to be friends with human-shaped robots than with specialized machines of unrecognizable shape. And I sometimes think that, in the desperate straits of humanity today, we would be grateful to have nonhuman friends, even if they are only the friends we build ourselves.”
