Isaac Asimov (c. January 2, 1920 – April 6, 1992), , originally Исаак Озимов but now transcribed into Russian as Азимов, Айзек, was a Russian-born American author and professor of biochemistry, a highly successful writer, best known for his works of science fiction and for his popular science books. Most of Asimov's popularized 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 his Guide to Science, the three volume set Understanding Physics, and Asimov's Chronology of Science and Discovery.
Asimov was one of the most prolific writers of all time, having written or edited more than 500 books and an estimated 9,000 letters and postcards. His works have been published in nine of the ten major categories of the Dewey Decimal System (the sole exception being the 100s; philosophy and psychology).
Asimov is widely considered a master of the science-fiction genre and, along with Robert A. Heinlein and Arthur C. Clarke, 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, both of which he later tied into the same fictional universe as the Foundation Series to create 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 penned numerous short stories, among them "Nightfall", which in 1964 was voted by the Science Fiction Writers of America the best short science fiction story of all time, a title many still honor. He also wrote mysteries and fantasy, as well as a great amount of nonfiction. Asimov wrote the Lucky Starr series of juvenile science-fiction novels using the pen name Paul French.
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, the magazine Asimov's Science Fiction, a Brooklyn, NY elementary school, and two different Isaac Asimov Awards are named in his honor.
His family emigrated to the United States when he was three years old. Since his parents always spoke Yiddish and English with him, he never learned Russian. Growing up in Brooklyn, New York, Asimov taught himself to read at the age of five, and remained fluent in Yiddish as well as English. His parents owned a succession of candy stores, and everyone in the family was expected to work in them.
Asimov attended New York City Public Schools, including Boys' High School, in Brooklyn, New York. From there he went on to Columbia University, from which he graduated in 1939, eventually returning to earn a Ph.D. in biochemistry in 1948. In between, he spent three years during World War II working as a civilian at the Philadelphia Navy Yard's Naval Air Experimental Station. After the war ended, he was drafted into the U.S. Army, serving for just under nine months before receiving an honorable discharge. In the course of his brief military career, he rose to the rank of corporal on the basis of his typing skills, and narrowly avoided participating in the 1946 atomic bomb tests at Bikini Atoll.
After completing his doctorate, Asimov joined the faculty of the Boston University School of Medicine, with which he remained associated thereafter. From 1958, this was in a non-teaching capacity, as he turned to writing full-time (his writing income had already exceeded his academic salary). Being tenured meant that he retained the title of associate professor, and in 1979 the university honored his writing by promoting him to full professor of biochemistry. Asimov's personal papers from 1965 are archived at the university's Mugar Memorial Library, to which he donated them at the request of curator Howard Gottlieb. The collection fills 464 boxes, on seventy-one metres of shelf space.
Asimov was a claustrophile; he enjoyed small, enclosed spaces. In the first volume of his autobiography, he recalls a childhood desire to own a magazine stand in a New York City Subway station, within which he could enclose himself and listen to the rumble of passing trains while reading.
Asimov was afraid of flying, only doing so twice in his entire life (once in the course of his work at the Naval Air Experimental Station, and once returning home from the army base in Oahu in 1946). He seldom traveled great distances, partly because his aversion to flying, complicated the logistics of long-distance travel. This phobia influenced several of his fiction works, such as the Wendell Urth mystery stories and the Robot novels featuring Elijah Baley. In his later years, he found he enjoyed traveling on cruise ships, and on several occasions he became part of the cruises' "entertainment," giving science-themed talks on ships such as the RMS Queen Elizabeth 2. Asimov was an able public speaker, and enjoyed speaking.
Asimov was a frequent fixture at science fiction conventions, where he remained friendly and approachable. He patiently answered tens of thousands of questions and other mail with postcards, and was pleased to give autographs. He was of medium height, stocky, with muttonchop whiskers and a distinct Brooklyn accent. His physical dexterity was very poor. He never learned to swim or ride a bicycle; however, he did learn to drive a car after he moved to Boston. In his humor book Asimov Laughs Again, he describes Boston driving as "anarchy on wheels."
Asimov's wide interests included his participation in his later years in organizations devoted to the comic operas of Gilbert and Sullivan and in The Wolfe Pack , a group of devotees of the Nero Wolfe mysteries written by Rex Stout. Indeed, his interest in Gilbert and Sullivan inspired his Foundation Trilogy, and many of his short stories mention or quote G&S. He was a prominent member of the Baker Street Irregulars, the leading Sherlock Holmes society. From 1985 until his death in 1992, he was president of the American Humanist Association; his successor was his friend and fellow writer Kurt Vonnegut. He was also a close friend of Star Trek creator Gene Roddenberry, and earned a screen credit on Star Trek: The Motion Picture for advice he gave during production (generally, confirming to Paramount Pictures that Roddenberry's ideas were legitimate science-fictional extrapolation).
In his last autobiography, Asimov wrote, "If I were not an atheist, I would believe in a God who would choose to save people on the basis of the totality of their lives and not the pattern of their words. I think he would prefer an honest and righteous atheist to a TV preacher whose every word is God, God, God, and whose every deed is foul, foul, foul. The same memoir states his belief that Hell is "the drooling dream of a sadist" crudely affixed to an all-merciful God; if even human governments were willing to curtail cruel and unusual punishments, wondered Asimov, why would punishment in the afterlife not be restricted to a limited term? Asimov rejected the idea that a human belief or action could merit infinite punishment. If an afterlife of just deserts existed, he claimed, the longest and most severe punishment would be reserved for those who "slandered God by inventing Hell. As his Treasury of Humor and Asimov Laughs Again record, he was willing to tell jokes involving the Judeo-Christian God, Satan, the Garden of Eden, and other religious topics, expressing the viewpoint that a good joke can do more to provoke thought than hours of philosophical discussion.
Asimov became a staunch supporter of the Democratic Party during the New Deal, and thereafter remained a political liberal. He was a vocal opponent of the Vietnam War in the 1960s and, in a television interview during the early 1970s, he publicly endorsed George McGovern. He was unhappy about what he considered an "irrationalist" viewpoint taken by many liberal political activists from the late 1960s and onwards. In his autobiography In Joy Still Felt, he recalls meeting the counterculture figure Abbie Hoffman; Asimov's impression was that the 1960s' counterculture heroes had ridden an emotional wave which, in the end, left them stranded in a "no-man's land of the spirit" from which he wondered if they would ever return. (This attitude is echoed by The Wave Speech in Hunter S. Thompson's Fear and Loathing in Las Vegas.) His defense of civil applications of nuclear power even after the Three Mile Island incident damaged his relations with some of his fellow liberals. In a letter reprinted in Yours, Isaac Asimov, he states that although he would prefer living in "no danger whatsoever" than near a nuclear reactor, he would still prefer a home near a nuclear power plant than in a slum on Love Canal or near "a Union Carbide plant producing methyl isocyanate" (referring to the Bhopal disaster). He issued many appeals for population control, reflecting a perspective articulated by people from Thomas Malthus through Paul R. Ehrlich. Asimov considered himself a feminist even before Women's Liberation became a widespread movement; he joked that he wished women to be free "because I hate it when they charge". More seriously, he argued that the issue of women's rights was closely connected to that of population control. Furthermore, he believed that homosexuality must be considered a "moral right" on population grounds, as must all consenting adult sexual activity that does not lead to reproduction (Yours, Isaac Asimov).
In the closing years of his life, Asimov blamed the deterioration of the quality of life that he perceived in New York City on the shrinking tax base caused by middle class flight to the suburbs. His last non-fiction book, Our Angry Earth (1991, co-written with his long-time friend science fiction author Frederik Pohl), deals with elements of the environmental crisis such as global warming and the destruction of the ozone layer.
Asimov's career can be divided into several time periods. His early career, dominated by science fiction, began with short stories in 1939 and novels in 1950. This lasted until about 1958, all but ending after publication of The Naked Sun. He began publishing nonfiction in 1952, co-authoring a college-level textbook called Biochemistry and Human Metabolism. Following the brief orbit of the first man-made satellite Sputnik I by the USSR in 1957, his production of nonfiction, particularly popular science books, greatly increased, with a consequent drop in his science fiction output. Over the next quarter century, he wrote only four science fiction novels. Starting in 1982, the second half of his science fiction career began with the publication of Foundation's Edge. From then until his death, Asimov published several more sequels and prequels to his existing novels, tying them together in a way he had not originally anticipated, making a unified series. There are, however, many inconsistencies in this unification, especially in his earlier stories.
Asimov believed that his most enduring contributions would be his "Three Laws of Robotics" and the Foundation Series (see Yours, Isaac Asimov, p. 329). Furthermore, the Oxford English Dictionary credits his science fiction for introducing the words positronic (an entirely fictional technology), psychohistory (which is also used for a different study on historical motivations) and robotics into the English language. Asimov coined the term robotics without suspecting that it might be an original word; at the time, he believed it was simply the natural analogue of words such as mechanics and hydraulics, but for robots. Unlike his word psychohistory, the word robotics continues in mainstream technical use with Asimov's original definition. Star Trek: The Next Generation featured androids with "positronic brains" giving Asimov full credit for 'inventing' this fictional technology.
In 1941, he published his 32nd story, "Nightfall", which has been described as one of "the most famous science-fiction stories of all time". In 1968 the Science Fiction Writers of America voted "Nightfall" the best science fiction short story ever written. In his short story collection Nightfall and Other Stories he wrote, "The writing of 'Nightfall' was a watershed in my professional career ... I was suddenly taken seriously and the world of science fiction became aware that I existed. As the years passed, in fact, it became evident that I had written a 'classic'".
"Nightfall" is an archetypal example of social science fiction, a term coined by Asimov to describe a new trend in the 1940s, led by authors including Asimov and Heinlein, away from gadgets and space opera and toward speculation about the human condition.
By 1941 Asimov had begun selling regularly to Astounding, which was then the field's leading magazine. From 1943 to 1949, all of his published science fiction appeared in Astounding.
In 1942 he published the first of his Foundation stories—later collected in the Foundation Trilogy: Foundation (1951), Foundation and Empire (1952), and Second Foundation (1953)—which recount the collapse and rebirth of a vast interstellar empire in a universe of the future. Taken together, they are his most famous work of science fiction, along with the Robot Series. Many years later, he continued the series with Foundation's Edge (1982) and Foundation and Earth (1986), and then went back to before the original trilogy with Prelude to Foundation (1988) and Forward the Foundation (1992). The series features his fictional science of Psychohistory in which the future course of the history of large populations can be predicted.
His positronic robot stories—many of which were collected in I, Robot (1950)—were begun at about the same time. They promulgated a set of rules of ethics for robots (see Three Laws of Robotics) and intelligent machines that greatly influenced other writers and thinkers in their treatment of the subject. One such short story, "The Bicentennial Man", was made into a film starring Robin Williams.
The 2004 film I, Robot, starring Will Smith, was based on a script by Jeff Vintar entitled Hardwired, with Asimov's ideas incorporated later after acquiring the rights to the I, Robot title. It is not related to the I, Robot script by Harlan Ellison, who collaborated with Asimov himself to create a version that captured the spirit of the original. Asimov is quoted as saying that Ellison's screenplay would lead to "the first really adult, complex, worthwhile science fiction movie ever made". The screenplay was published in book form in 1994, after hopes of seeing it in film form were becoming slim.
Besides movies, his Foundation and Robot stories have inspired other derivative works of science fiction literature, many by well-known and established authors such as Roger MacBride Allen, Greg Bear, Gregory Benford and David Brin. These appear to have been done with the blessing, and often at the request of, Asimov's widow Janet Asimov.
In 1948 he also wrote a spoof science article, "The Endochronic Properties of Resublimated Thiotimoline". At the time, Asimov was preparing for his own doctoral dissertation. Fearing a prejudicial reaction from his Ph.D. evaluation board, he asked his editor that it be released under a pseudonym, yet it appeared under his own name. During his oral examination shortly thereafter, Asimov grew concerned at the scrutiny he received. At the end of the examination, one evaluator turned to him, smiling, and said "Mr. Asimov, tell us something about the thermodynamic properties of the compound thiotimoline". After a 20-minute wait, he was summoned back into the Examination Room and congratulated as "Dr. Asimov."
In 1949, book publisher Doubleday's science fiction editor Walter I. Bradbury accepted Asimov's unpublished novel "Grow Old Along With Me" for publication, and it appeared under the Doubleday imprint in January 1950 as Pebble in the Sky. Doubleday went on to publish four more original science fiction novels by Asimov in the 1950s, along with the six juvenile Lucky Starr novels under the pseudonym Paul French. Doubleday also published collections of Asimov's short stories, beginning with The Martian Way and Other Stories in 1955. The early 1950s also saw Gnome Press publish Asimov's positronic robot stories as I, Robot and his Foundation stories as the three books of the Foundation Trilogy.
When new science fiction magazines, notably Galaxy Magazine and The Magazine of Fantasy & Science Fiction, appeared in the 1950s, Asimov began publishing short stories in them as well. He would later refer to the 1950s as his "golden decade". A number of these stories are included in his Best of anthology, including "The Last Question" (1956), on the ability of humankind to cope with and potentially reverse the process of entropy. It was his personal favorite and considered by many to be equal to "Nightfall". Asimov wrote of it in 1973:
In December 1974, the former Beatle Paul McCartney approached Asimov and asked him if he could write the screenplay for a science-fiction movie musical. McCartney had a vague idea for the plot and a small scrap of dialogue; he wished to make a film about a rock band whose members discover they are being impersonated by a group of extraterrestrials. The band and their impostors would likely be played by McCartney's group Wings, then at the height of their career. Intrigued by the idea, although he was not generally a fan of rock music, Asimov quickly produced a "treatment" or brief outline of the story. He adhered to McCartney's overall idea, producing a story he felt to be moving and dramatic. However, he did not make use of McCartney's brief scrap of dialogue, and probably in consequence, McCartney rejected the story. The treatment now exists only in Boston University's archives.
Beginning in 1977, he lent his name to Isaac Asimov's Science Fiction Magazine (now Asimov's Science Fiction) and penned an editorial for each issue. There was also a short-lived Asimov's SF Adventure Magazine and a companion Asimov's Science Fiction Anthology reprint series, published as magazines (in the same manner as stablemates Ellery Queen's Mystery Magazine and Alfred Hitchcock's Mystery Magazine's "anthologies").
Meanwhile, the monthly Magazine of Fantasy and Science Fiction invited him to continue his regular non-fiction column, begun in the now-folded bimonthly companion magazine Venture Science Fiction Magazine, ostensibly dedicated to popular science, but with Asimov having complete editorial freedom. The first of the F&SF columns appeared in November of 1958, and they followed uninterrupted thereafter, with 399 entries, until Asimov's terminal illness. These columns, periodically collected into books by his principal publisher, Doubleday, helped make Asimov's reputation as a "Great Explainer" of science, and were referred to by him as his only pop-science writing in which he never had to assume complete ignorance of the subjects at hand on the part of his readers. The popularity of his first wide-ranging reference work, The Intelligent Man's Guide to Science, also allowed him to give up most of his academic responsibilities and become essentially a full-time freelance writer.
Asimov wrote several essays on the social contentions of his time, including "Thinking About Thinking" and "Science: Knock Plastic" (1967).
The great variety of information covered in Asimov's writings once prompted Kurt Vonnegut to ask, "How does it feel to know everything?" Asimov replied that he only knew how it felt to have the reputation of omniscience—"Uneasy". (See In Joy Still Felt, chapter 30.) In the introduction to his story collection Slow Learner, Thomas Pynchon admitted that he relied upon Asimov's science popularizations (and the Oxford English Dictionary) to provide his knowledge of entropy.
It is a mark of the friendship and respect accorded Asimov by Arthur C. Clarke that the so-called "Asimov-Clarke Treaty of Park Avenue", put together as they shared a cab ride along Park Avenue in New York, stated that Asimov was required to insist that Clarke was the best science fiction writer in the world (reserving second best for himself), while Clarke was required to insist that Asimov was the best science writer in the world (reserving second best for himself). Thus the dedication in Clarke's book Report on Planet Three (1972) reads: "In accordance with the terms of the Clarke-Asimov treaty, the second-best science writer dedicates this book to the second-best science-fiction writer."
He published Asimov's Guide to the Bible in two volumes— covering the Old Testament in 1967 and the New Testament in 1969— and then combined them into one 1,300-page volume in 1981. Complete with maps and tables, the guide goes through the books of the Bible in order, explaining the history of each one and the political influences that affected it, as well as biographical information about the important characters. His interest in literature manifested itself in several annotations of literary works, including Asimov's Guide to Shakespeare (1970), Asimov's Annotated Paradise Lost (1974), and The Annotated Gulliver's Travels (1980).
Asimov was also a noted mystery author and a frequent contributor to Ellery Queen's Mystery Magazine. He began by writing science fiction mysteries such as his Wendall Urth stories but soon moved on to writing "pure" mysteries. He only published two full-length mystery novels but he wrote several stories about the Black Widowers, a group of men who met monthly for dinner, conversation, and a puzzle. He got the idea for the Widowers from his own association in a stag group called the Trap Door Spiders and all of the main characters (with the exception of the waiter, Henry, who he admitted resembled Wodehouse's Jeeves) were modeled after his closest friends.
Toward the end of his life, Asimov published a series of collections of limericks, mostly written by himself, starting with Lecherous Limericks, which appeared in 1975. Limericks: Too Gross, whose title displays Asimov's love of puns, contains 144 limericks by Asimov and an equal number by John Ciardi. He even created a slim volume of Sherlockian limericks (and embarrassed one fan by autographing her copy with an impromptu limerick that rhymed 'Nancy' with 'romancy'). Asimov featured Yiddish humor in Azazel, The Two Centimeter Demon. The two main characters, both Jewish, talk over dinner, or lunch, or breakfast, about anecdotes of "George" and his friend Azazel. Asimov's Treasury of Humor is both a working joke book and a treatise propounding his views on humor theory. According to Asimov, the most essential element of humor is an abrupt change in point of view, one that suddenly shifts focus from the important to the trivial, or from the sublime to the ridiculous.
Particularly in his later years, Asimov to some extent cultivated an image of himself as an amiable lecher. In 1971, as a response to the popularity of sexual guidebooks such as The Sensuous Woman (by "J") and The Sensuous Man (by "M"), Asimov published The Sensuous Dirty Old Man under the byline "Dr. 'A'", but with his full name prominently displayed on the cover.
Asimov published two volumes of autobiography: In Memory Yet Green (1979) and In Joy Still Felt (1980). A third autobiography, I. Asimov: A Memoir, was published in April 1994. The epilogue was written by his widow Janet Asimov a decade after his death. It's Been a Good Life (2002), edited by Janet, is a condensed version of his three autobiographies. He also published three volumes of retrospectives of his writing, Opus 100 (1969), Opus 200 (1979), and Opus 300 (1984).
Asimov and Star Trek creator Gene Roddenberry developed a unique relationship during Star Trek's initial launch in the late 60s. Asimov wrote a critical essay on Star Trek 's scientific accuracy for TV Guide magazine. Roddenberry retorted respectfully with a personal letter explaining the limitations of accuracy when writing a weekly series. Asimov corrected himself with a follow-up essay to TV Guide claiming despite its inaccuracies, that Star Trek was a fresh and intellectually challenging science fiction television show. The two remained friends to the point where Asimov even served as an advisor on a number of Star Trek projects.
Much of Asimov's fiction dealt with themes of paternalism. His first robot story, "Robbie", concerned a robotic nanny. "Lenny" deals with the capacity of robopsychologist Susan Calvin to feel maternal love towards a robot whose positronic brain capacities are those of a 3-year-old. As the robots grew more sophisticated, their interventions became more wide-reaching and subtle. In "Evidence", the story revolves around a candidate who successfully runs for office who may be a robot masquerading as a human. In "The Evitable Conflict", the robots run humanity from behind the scenes, acting as nannies to the whole species.
Later, in The Robots of Dawn and Robots and Empire, a robot develops what he calls the Zeroth Law of Robotics, which states that: "A robot may not injure humanity, nor, through inaction, allow humanity to come to harm". He also decides that robotic presence is stifling humanity's freedom, and that the best course of action is for the robots to phase themselves out. A non-robot, time travel novel, The End of Eternity, features a similar conflict and resolution. The significance of the Zeroth Law is that it outweighs and supersedes all other Laws of Robotics: if a robot finds himself in a situation whereby he must murder one or more humans (a direct violation of the First Law of Robotics) in order to protect all of humanity (and preserve the Zeroth Law), then the robot's positronic programming will require him to commit murder for humanity's sake. Only highly advanced robots (such as Daneel and Giskard) could comprehend this law.
In The Foundation Series (which did not originally have robots), a scientist implements a semi-secret plan to create a new galactic empire over the course of 1,000 years. This series has its version of Platonic guardians, called the Second Foundation, to perfect and protect the plan. When Asimov stopped writing the series in the 1950s, the Second Foundation was depicted as benign protectors of humanity. When he revisited the series in the 1980s, he made the paternalistic themes even more explicit.
Foundation's Edge introduced the planet Gaia, obviously based on the Gaia hypothesis. Every animal, plant, and mineral on Gaia participated in a shared consciousness, forming a single super-mind working together for the greater good. In Foundation and Earth, the protagonist starts searching for the Earth, thinking that there he could find the answer of why he decided, in Foundation's Edge, that Galaxia was the right choice to take. Gaia is one of Asimov's best attempts at exploring the possibility of a collective awareness, and is compounded further in Nemesis, in which the planet Erythro composed primarily of prokaryotic life has a mind of its own and seeks communion with human beings.
Foundation and Earth introduces robots to the Foundation universe. Two of Asimov's last novels, Prelude to Foundation and Forward the Foundation, explore their behavior in fuller detail. The robots are depicted as covert operatives, acting for the benefit of humanity.
Another frequent theme, perhaps the reverse of paternalism, is social oppression. The Currents of Space takes place on a planet where a unique plant fiber is grown; the agricultural workers there are exploited by the aristocrats of a nearby planet. In The Stars, Like Dust, the hero helps a planet that is oppressed by an arrogant interplanetary empire, the Tyranni.
Often the victims of oppression are either Earth people (as opposed to colonists on other planets) or robots. In "The Bicentennial Man", a robot fights prejudice to be accepted as a human. In The Caves of Steel, the people of Earth resent the wealthier "Spacers" and in turn treat robots (associated with the Spacers) in ways reminiscent of how whites treated blacks, such as addressing robots as "boy". Pebble in the Sky shows an analogous situation: the Galactic Empire rules Earth and its people use such terms as "Earthie-squaw", but Earth is a theocratic dictatorship that enforces euthanasia of anyone older than 60. One hero is Bel Arvardan, an upper-class Galactic archaeologist who must overcome his prejudices. The other is Joseph Schwartz, a 62-year-old 20th century American who had emigrated from Europe, where his people were persecuted (he is quite possibly Jewish), and is accidentally transported forward in time to Arvardan's period. He must decide whether to help a downtrodden society that thinks he should be dead.
Yet another frequent theme in Asimov is rational thought. He invented the science-fiction mystery with the novel The Caves of Steel and the stories in Asimov's Mysteries, usually playing fair with the reader by introducing early in the story any science or technology involved in the solution. Later, he produced non-SF mysteries, including the novel Murder at the ABA (1976) and the "Black Widowers" and "Union Club" short stories, in which he followed the same rule. In his fiction, important scenes are often essentially debates, with the more rational, humane—or persuasive—side winning.
Except for two stories—"Liar!" and "Evidence"—they are not stories in which character plays a significant part. Virtually all plot develops in conversation with little if any action. Nor is there a great deal of local color or description of any kind. The dialogue is, at best, functional and the style is, at best, transparent.... The robot stories—and, as a matter of fact, almost all Asimov fiction—play themselves on a relatively bare stage.
Gunn observes that there are places where Asimov's style rises to the demands of the situation; he cites the climax of "Liar!" as an example. Sharply drawn characters occur at key junctures of his storylines: In addition to Susan Calvin in "Liar!" and "Evidence", we find Arkady Darell in Second Foundation, Elijah Baley in The Caves of Steel and Hari Seldon in the Foundation prequels.
Asimov was also criticised for the lack of sex and aliens in his science fiction. Asimov once explained that his reluctance to write about aliens came from an incident early in his career when Astounding's editor John Campbell rejected one of his early science fiction stories because the alien characters were portrayed as superior to the humans. He decided that, rather than write weak alien characters, he would not write about aliens at all. Nevertheless, in response to these criticisms he wrote The Gods Themselves, which contains aliens, sex, and alien sex. Asimov said that of all his writings, he was most proud of the middle section of The Gods Themselves, the part which deals with those themes.
In the Hugo Award-winning novella "Gold", Asimov describes an author clearly based on himself who has one of his books (The Gods Themselves) adapted into a "compu-drama", essentially photo-realistic computer animation. The director criticizes the fictionalized Asimov ("Gregory Laborian") for having an extremely nonvisual style making it difficult to adapt his work, and the author explains that he relies on ideas and dialogue rather than description to get his points across.
Others have criticised him for a lack of strong female characters in his early work. In his autobiographical writings he acknowledges this, and responds by pointing to inexperience. His later novels, written with more female characters but in essentially the same prose style as his early SF stories, brought this matter to a wider audience. For example, the August 25, 1985 Washington Post's "Book World" section reports of Robots and Empire as follows:
In 1940, Asimov's humans were stripped-down masculine portraits of Americans from 1940, and they still are. His robots were tin cans with speedlines like an old Studebaker, and still are; the Robot tales depended on an increasingly unworkable distinction between movable and unmovable artificial intelligences, and still do. In the Asimov universe, because it was conceived a long time ago, and because its author abhors confusion, there are no computers whose impact is worth noting, no social complexities, no genetic engineering, aliens, arcologies, multiverses, clones, sin or sex; his heroes (in this case R. Daneel Olivaw, whom we first met as the robot protagonist of The Caves of Steel and its sequels) feel no pressure of information, raw or cooked, as the simplest of us do today; they suffer no deformation from the winds of the Asimov future, because it is so deeply and strikingly orderly.
Be that as it may, a considerable portion of such criticism boils down to the charge that Asimov's works are simply dated. More precisely, some details of Asimov's imaginary future technology as he described in the 1940s and 1950s have not aged well. He, for example, described powerful robots and computers from the distant future as still using punch cards or punched tape and engineers using slide rules. In one dramatic scene in Foundation and Empire, a character gets the news by buying a paper at a vending machine.
In addition, his stories also have occasional internal contradictions: names and dates given in The Foundation Series do not always agree with one another, for example. Some such errors may plausibly be due to mistakes the characters make, since characters in Asimov stories are seldom fully informed about their own situations. Other contradictions resulted from the many years elapsed between the time Asimov began the Foundation series and when he resumed work on it; occasionally, advances in scientific knowledge forced him to revise his own fictional history.
Other than books by Gunn and Patrouch, there is a relative dearth of "literary" criticism on Asimov (particularly when compared to the sheer volume of his output). Cowart and Wymer's Dictionary of Literary Biography (1981) gives a possible reason:
His words do not easily lend themselves to traditional literary criticism because he has the habit of centering his fiction on plot and clearly stating to his reader, in rather direct terms, what is happening in his stories and why it is happening. In fact, most of the dialogue in an Asimov story, and particularly in the Foundation trilogy, is devoted to such exposition. Stories that clearly state what they mean in unambiguous language are the most difficult for a scholar to deal with because there is little to be interpreted.
In fairness, Gunn's and Patrouch's respective studies of Asimov both take the stand that a clear, direct prose style is still a style. Gunn's 1982 book goes into considerable depth commenting upon each of Asimov's novels published to that date. He does not praise all of Asimov's fiction (nor does Patrouch), but he does call some passages in The Caves of Steel "reminiscent of Proust". When discussing how that novel depicts night falling over futuristic New York City, Gunn says that Asimov's prose "need not be ashamed anywhere in literary society".
Although he prided himself on his unornamented prose style (for which he credited Clifford Simak as an early influence), Asimov also enjoyed giving his longer stories complicated narrative structures, often by arranging chapters in non-chronological ways. Some readers have been put off by this, complaining that the nonlinearity is not worth the trouble and adversely affects the clarity of the story. For example, the first third of The Gods Themselves begins with Chapter 6, then backtracks to fill in earlier material. (John Campbell advised Asimov to begin his stories as late in the plot as possible. This advice helped Asimov create "Reason," one of the early Robot stories. See In Memory Yet Green for details of that time period.) Patrouch found that the interwoven and nested flashbacks of The Currents of Space did serious harm to that novel, to such an extent that only a "dyed-in-the-kyrt Asimov fan" could enjoy it. Asimov's tendency to contort his timelines is perhaps most apparent in his later novel Nemesis, in which one group of characters live in the "present" and another group starts in the "past", beginning fifteen years earlier and gradually moving toward the time period of the first group.
In 2002, Donald Palumbo, an English professor at East Carolina University, published Chaos Theory, Asimov's Foundations and Robots, and Herbert’s Dune: The Fractal Aesthetic of Epic Science Fiction. This includes a review of Asimov's narrative structures that compares them with the scientific concepts of fractals and chaos. Palumbo finds that though the traditional interests of literature (such as symbolism and characterization) are often somewhat lacking or even absent, a fascination with the Foundation and Robot metaseries remains. He determines that the purposeful complexities of the narrative build unusual symmetric and recursive structures to be perceived by the mind's eye. This volume contains some of the most scholarly and in-depth criticism of Asimov to date.
John Jenkins, who has reviewed the vast majority of Asimov's written output, once observed:
It has been pointed out that most science fiction writers since the 1950s have been affected by Asimov, either modeling their style on his or deliberately avoiding anything like his style.
