Isaac Asimov on Science fiction

“Science fiction is that branch of literature that deals with human responses to changes in the level of science and technology.”

“Science fiction always bases its future visions on changes in the levels of science and technology. And the reason for that consistency is simply that—in reality—all other changes throughout history have been irrelevant and trivial.”

“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, the concept around which it revolves, has become crucial to our salvation if we are to be saved at all.”

“I don't know of any science fiction writer who really attempts to be a prophet. Such authors accomplish their tasks not by being correct in their predictions, necessarily, but merely by hammering home—in story after story—the notion that life is going to be different.”

“The rockets that have made spaceflight possible are an advance that, more than any other technological victory of the twentieth century, was grounded in science fiction… . One thing that no science fiction writer visualized, however, as far as I know, was that the landings on the Moon would be watched by people on Earth by way of television.”
