Isaac Asimov Quotes
page 5

Isaac Asimov was a Jewish-American writer and professor of biochemistry at Boston University. He was known for his works of science fiction and popular science. Asimov was a prolific writer, and wrote or edited more than 500 books and an estimated 90,000 letters and postcards. His books have been published in 9 of the 10 major categories of the Dewey Decimal Classification.

Asimov wrote hard science fiction and, along with Robert A. Heinlein and Arthur C. Clarke, he was considered one of the "Big Three" science fiction writers during his lifetime. Asimov's most famous work is the Foundation Series; his other major series are the Galactic Empire series and the Robot series. The Galactic Empire novels are explicitly set in earlier history of the same fictional universe as the Foundation series. Later, beginning with Foundation's Edge, he linked this distant future to the Robot and Spacer stories, creating a unified "future history" for his stories much like those pioneered by Robert A. Heinlein and previously produced by Cordwainer Smith and Poul Anderson. He wrote hundreds of short stories, including the social science fiction novelette "Nightfall", which in 1964 was voted by the Science Fiction Writers of America the best short science fiction story of all time. Asimov wrote the Lucky Starr series of juvenile science-fiction novels using the pen name Paul French.

Asimov also wrote mysteries and fantasy, as well as much nonfiction. Most of his popular science books explain scientific concepts in a historical way, going as far back as possible to a time when the science in question was at its simplest stage. He often provides nationalities, birth dates, and death dates for the scientists he mentions, as well as etymologies and pronunciation guides for technical terms. Examples include Guide to Science, the three-volume set Understanding Physics, and Asimov's Chronology of Science and Discovery, as well as works on astronomy, mathematics, history, William Shakespeare's writing, and chemistry.

Asimov was a long-time member and vice president of Mensa International, albeit reluctantly; he described some members of that organization as "brain-proud and aggressive about their IQs". He took more joy in being president of the American Humanist Association. The asteroid 5020 Asimov, a crater on the planet Mars, a Brooklyn elementary school, and a literary award are named in his honor.

Isaac Asimov Quotes

“It is a mistake,” he said, “to suppose that the public wants the environment protected or their lives saved and that they will be grateful to any idealist who will fight for such ends. What the public wants is their own individual comfort. We know that well enough from our experience in the environmental crisis of the twentieth century.”

“For it is the chief characteristic of the religion of science, that it works, and that such curses as that of Aporat’s are really deadly.”

“The machine is only a tool after all, which can help humanity progress faster by taking some of the burdens of calculations and interpretations off its back. The task of the human brain remains what it has always been; that of discovering new data to be analyzed, and of devising new concepts to be tested.”

Isaac Asimov book I, Robot

“The Evitable Conflict”, p. 187
I, Robot (1950)

“Science Digest asked me to see the movie Close Encounters of the Third Kind and write an article for them on the science it contained. I saw the picture and was appalled. I remained appalled even after a doctor’s examination had assured me that no internal organs had been shaken loose by its ridiculous soundwaves. (If you can’t be good, be loud, some say, and Close Encounters was very loud.) … Hollywood must deal with large audiences, most of whom are utterly unfamiliar with good science fiction. It has to bend to them, meet them at least half-way. Fully appreciating that, I could enjoy Planet of the Apes and Star Wars. Star Wars was entertainment for the masses and did not try to be anything more. Leave your sophistication at the door, get into the spirit, and you can have a fun ride. … Seeing a rotten picture for the special effects is like eating a tough steak for the smothered onions, or reading a bad book for the dirty parts. Optical wizardry is something a movie can do that a book can’t but it is no substitute for a story, for logic, for meaning. It is ornamentation, not substance. In fact, whenever a science fiction picture is praised overeffusively for its special effects, I know it’s a bad picture. Is that all they can find to talk about?”

“There was no denying that he would always be conscious of the fact that an Earthman was an Earthman. He couldn’t help that.

“To be sure, the Bible contains the direct words of God. How do we know? The Moral Majority says so. How do they know? They say they know and to doubt it makes you an agent of the Devil or, worse, a Lbr-l Dm-cr-t. And what does the Bible textbook say? Well, among other things it says the earth was created in 4004 BC (Not actually, but a Moral Majority type figured that out three and a half centuries ago, and his word is also accepted as inspired.) The sun was created three days later. The first male was molded out of dirt, and the first female was molded, some time later, out of his rib. As far as the end of the universe is concerned, the Book of Revelation (6:13-14) says: "And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind." … Imagine the people who believe such things and who are not ashamed to ignore, totally, all the patient findings of thinking minds through all the centuries since the Bible was written. And it is these ignorant people, the most uneducated, the most unimaginative, the most unthinking among us, who would make themselves the guides and leaders of us all; who would force their feeble and childish beliefs on us; who would invade our schools and libraries and homes. I personally resent it bitterly.”

“The fact that the general incidence of leukemia has doubled in the last two decades may be due, partly, to the increasing use of x-rays for numerous purposes. The incidence of leukemia in doctors, who are likely to be so exposed, is twice that of the general public. In radiologists … the incidence is ten times greater.”

A few less calories taken in each day and a few more used up will decrease weight, slowly, to be sure, but without undue misery. And with better long-range results too.”
