Stranger in a Strange Land is a 1961 science fiction novel by American author Robert A. Heinlein. It tells the story of Valentine Michael Smith, a human who comes to Earth in early adulthood after being born on the planet Mars and raised by Martians, and explores his interaction with and eventual transformation of Terran culture.

The title "Stranger in a Strange Land" is a direct quotation from the King James Bible (taken from Exodus 2:22). The working title for the book was "A Martian Named Smith", which was also the name of the screenplay started by a character at the end of the novel.

Heinlein's widow Virginia arranged to have the original unedited manuscript published in 1991, three years after Heinlein's death. Critics disagree about which version is superior, but Heinlein preferred the original manuscript and described the heavily edited version as "telegraphese".

In 2012, the Library of Congress named it one of 88 "Books that Shaped America".

Plot

The story focuses on a human raised on Mars and his adaptation to and understanding of humans and their culture. It is set in a post-Third World War United States, where organized religions are politically powerful. There is a World Federation of Free Nations, including the demilitarized US, with a world government supported by Special Service troops.

Prior to WWIII the manned spacecraft Envoy is launched toward Mars, but all contact is lost shortly before landing. Twenty-five years later, the spacecraft Champion makes contact with the inhabitants of Mars and finds a single survivor, Valentine Michael Smith. Born on the Envoy, he was raised entirely by the Martians. He is ordered by them to accompany the returning expedition.

Because Smith is unaccustomed to the conditions on Earth, he is confined at Bethesda Hospital, where, having never seen a human female, he is attended by male staff only. Seeing that restriction as a challenge, Nurse Gillian Boardman eludes the guards and goes in to see Smith. By sharing a glass of water with him, she inadvertently becomes his first "water brother", which is considered to be a profound relationship by the Martians as water on Mars is extremely scarce.

Gillian tells her lover, reporter Ben Caxton, about her experience with Smith. Ben explains that as heir to the entire exploration party, Smith is extremely wealthy, and following a legal precedent set during the colonisation of the Moon, he could be considered owner of Mars itself. His arrival on Earth has prompted a political power struggle that puts his life in danger. Ben persuades her to bug Smith's room and publishes stories to bait the government into releasing him. Ben is seized by the government, and Gillian persuades Smith to leave the hospital with her. When government agents catch up with them, Smith makes the agents vanish and then is so shocked by Gillian's terrified reaction that he enters a semblance of catatonia. Gillian, remembering Ben's earlier suggestion, conveys Smith to Jubal Harshaw, a famous author who is also a physician and a lawyer.

Smith continues to demonstrate psychic abilities and superhuman intelligence, coupled with a childlike naïveté. When Harshaw tries to explain religion to him, Smith understands the concept of God only as "one who groks", which includes every extant organism. That leads him to express the Martian concept of life as the phrase "Thou art God" although he knows that to be a bad translation. Many other human concepts such as war, clothing, and jealousy are strange to him, and the idea of an afterlife is a fact that he takes for granted because Martian society is directed by "Old Ones", the spirits of Martians who have "discorporated". It is also customary for loved ones and friends to eat the bodies of the dead in a rite similar to Holy Communion. Eventually, Harshaw arranges freedom for Smith and recognition that human law, which would have granted ownership of Mars to Smith, has no applicability to a planet that is already inhabited by intelligent life.

Still inexhaustibly wealthy and now free to travel, Smith becomes a celebrity and is feted by the Earth's elite. He investigates many religions, including the Fosterite Church of the New Revelation, a populist megachurch in which sexuality, gambling, alcohol consumption, and similar activities are allowed and even encouraged and considered "sinning" only when they are not under church auspices. The Church of the New Revelation is organized in a complexity of initiatory levels: an outer circle, open to the public; a middle circle of ordinary members, who support the church financially; and an inner circle of the "eternally saved", attractive, highly sexed men and women, who serve as clergy and recruit new members. The Church owns many politicians and uses violence against those who oppose it. Smith also has a brief career as a magician in a carnival (performing actual miracles), in which he and Gillian befriend the show's tattooed lady, an "eternally saved" Fosterite named Patricia Paiwonski.

Eventually, Smith starts a Martian-influenced "Church of All Worlds", combining elements of the Fosterite cult (especially the sexual aspects) with Western esotericism, whose members learn the Martian language and thus acquire the ability to truly "grok" the nature of reality, granting them psychokinesis. The church is eventually besieged by Fosterites for practicing "blasphemy", and the church building is destroyed, but unknown to the public, Smith's followers teleport to safety. Smith is arrested by the police, but escapes and returns to his followers, later explaining to Jubal that his gigantic fortune has been bequeathed to the Church. With that wealth and their new abilities, Church members will be able to reorganize human societies and cultures. Eventually, those who cannot or will not learn Smith's methods will die out, leaving Homo Superior. That incidentally may save Earth from eventual destruction by the Martians, who were responsible for the destruction of the fifth planet eons ago (resulting in the asteroid belt).

Smith is killed by a mob raised against him by the Fosterites. From the afterlife, he speaks briefly to grief-stricken Jubal to dissuade him from suicide. Having consumed a small portion of Smith's remains in keeping with Martian custom, Jubal and some of the Church members return to Jubal's home to regroup and prepare for their new evangelical role founding congregations. Meanwhile, Smith reappears in the afterlife to replace the Fosterites' eponymous founder, amid hints that Smith was an incarnation of the Archangel Michael.

Characters

Heinlein named his main character "Smith" because of a speech he made at a science fiction convention regarding the unpronounceable names assigned to extraterrestrials. After describing the importance of establishing a dramatic difference between humans and aliens, Heinlein concluded, "Besides, whoever heard of a Martian named Smith?" The title Stranger In a Strange Land is taken from the King James Version of Exodus 2:22, "And she bore him a son, and he called his name Gershom: for he said, I have been a stranger in a strange land".

In the preface to the uncut, original version of the book re-issued in 1991, Heinlein's widow, Virginia, wrote: "The given names of the chief characters have great importance to the plot. They were carefully selected: Jubal means 'the father of all,' Michael stands for 'Who is like God?'".

Valentine Michael Smith
Known as Michael Smith or "Mike", the "Man from Mars" is born on Mars in the interval between the landing of the Envoy and the arrival of the Champion. He is 20 years old when the Champion arrives and brings him to Earth.
Gillian (Jill) Boardman
A nurse at Bethesda Hospital who sneaks Mike out of government custody. She plays a key role in introducing him to human culture and becomes one of his closest confidantes and a central figure in the Church of All Worlds, which Mike develops.
Ben Caxton
An early love interest of Jill and an investigative journalist (Jill sees him as of the "lippmann", political, rather than the "winchell", or celebrity gossip inclination), who masterminds Mike's initial freedom from custody. He joins Mike's inner circle but remains somewhat skeptical at first of the social order that it develops.
Jubal Harshaw
A popular writer, lawyer, and doctor, now semi-retired to a house in the Pocono Mountains, an influential but reclusive public figure who provides pivotal support for Mike's independence and a safe haven for him. Elderly but in good health, he serves as a father figure for the inner circle while keeping a suspicious distance from it. The character's name was chosen by Heinlein to have unusual overtones, like Jonathan Hoag. Mike enshrines him (much to Harshaw's initial chagrin) as the patron saint of the church he founds.
Anne, Miriam, Dorcas
Harshaw's three personal/professional secretaries, who live with him and take turns as his "front", responding to his instructions. Anne is certified as a Fair Witness, empowered to provide objective legal testimony about events that she witnesses. All three become early acolytes of Michael's church.
Duke, Larry
Handymen who work for Harshaw and live in his estate; they also become central members of the church.
Dr. "Stinky" Mahmoud
A semanticist, crew member of the Champion and the second human (after Mike) to gain a working knowledge of the Martian language but does not "grok" the language. He becomes a member of the church while retaining his Muslim faith.
Patty Paiwonski
A "tattooed lady" and snake handler at the circus Mike and Jill join for a time. She has ties to the Fosterite church, which she retains as a member of Mike's inner circle.
Joseph Douglas
Secretary-General of the Federation of Free States, which has evolved indirectly from the United Nations into a true world government.
Alice Douglas
Sometimes called "Agnes", Joe Douglas' wife. As the First Lady, she manipulates her husband, making major economic, political, and staffing decisions and frequently consults astrologer Becky Vesant for major decisions.
Foster
The founder of the Church of the New Revelation (Fosterite), who now exists as an archangel.
Digby
Foster's successor as head of the Fosterite Church; he becomes an archangel under Foster after Mike "discorporates" him.

Reception

Heinlein's deliberately provocative book generated considerable controversy. The free love and commune living aspects of the Church of All Worlds led to the book's exclusion from school reading lists. After it was rumored to be associated with Charles Manson, it was removed from school libraries as well.

Writing in The New York Times, Orville Prescott received the novel caustically, describing it as a "disastrous mishmash of science fiction, laborious humor, dreary social satire and cheap eroticism"; he characterized Stranger in a Strange Land as "puerile and ludicrous", saying "when a non-stop orgy is combined with a lot of preposterous chatter, it becomes unendurable, an affront to the patience and intelligence of readers". Galaxy reviewer Floyd C. Gale rated the novel 3.5 stars out of five, saying "the book's shortcomings lie not so much in its emancipation as in the fact that Heinlein has bitten off too large a chewing portion".

Despite such reviews, Stranger in a Strange Land won the 1962 Hugo Award for Best Novel and became the first science fiction novel to enter The New York Times Book Review's best-seller list. In 2012, it was included in a Library of Congress exhibition of "Books That Shaped America".

Critics have also suggested that Jubal Harshaw is actually a stand-in for Robert Heinlein himself, based on similarities in career choice and general disposition, though Harshaw is much older than Heinlein was at the time of writing. Literary critic Dan Schneider wrote that Harshaw's belief in his own free will, was one "which Mike, Jill, and the Fosterites misinterpret as a pandeistic urge, 'Thou art God!'"

Development

Heinlein got the idea for the novel when he and his wife Virginia were brainstorming one evening in 1948. She suggested a new version of Rudyard Kipling's The Jungle Book (1894), but with a child raised by Martians instead of wolves. He decided to go further with the idea and worked on the story on and off for more than a decade, believing that contemporary society was not yet ready for it. His editors at Putnam then required him to cut its 220,000-word length down to 160,000 words before publication.

Originally titled The Heretic, the book was written in part as a deliberate attempt to challenge social mores. In the course of the story, Heinlein uses Smith's open-mindedness to reevaluate such institutions as religion, money, monogamy, and the fear of death. Heinlein completed writing it ten years after he had plotted it out in detail. He later wrote, "I had been in no hurry to finish it, as that story could not be published commercially until the public mores changed. I could see them changing and it turned out that I had timed it right."

The book was dedicated in part to science fiction author Philip José Farmer, who had explored sexual themes in works such as The Lovers (1952). It was also influenced by the satiric fantasies of James Branch Cabell.

Heinlein was surprised that some readers thought the book described how he believed society should be organized, explaining: "I was not giving answers. I was trying to shake the reader loose from some preconceptions and induce him to think for himself, along new and fresh lines. In consequence, each reader gets something different out of that book because he himself supplies the answers ... It is an invitation to think – not to believe."

Influence

The book significantly influenced modern culture in a variety of ways.

Church of All Worlds

A central element of the second half of the novel is the religious movement founded by Smith, the "Church of All Worlds", an initiatory mystery religion blending elements of paganism and revivalism, with psychic training and instruction in the Martian language. In 1968, Oberon Zell-Ravenheart (then Tim Zell) founded the Church of All Worlds, a Neopagan religious organization modeled in many ways after the fictional organization in the novel. The spiritual path included several ideas from the book, including polyamory, non-mainstream family structures, social libertarianism, water-sharing rituals, an acceptance of all religious paths by a single tradition, and the use of several terms such as "grok", "Thou art God", and "Never Thirst".

Heinlein objected to Zell's lumping him with other writers such as Ayn Rand and Robert Rimmer; Heinlein felt that those writers used their art for propaganda purposes, while he simply asked questions of the reader, expecting each reader to answer for him- or herself. He wrote to Zell in a letter: "... each reader gets something different out of the book because he himself supplies the answers. If I managed to shake him loose from some prejudice, preconception or unexamined assumption, that was all I intended to do."

Though Heinlein was neither a member nor a promoter of the Church, it was formed including frequent correspondence between Zell and Heinlein, and Heinlein was a paid subscriber to the Church's magazine Green Egg. This Church still exists as a 501(c)(3) recognized religious organization incorporated in California, with membership worldwide, and it remains an active part of the neopagan community.

Grok

The word "grok", coined in the novel, made its way into the English language. In Heinlein's invented Martian language, "grok" literally means "to drink" and figuratively means "to comprehend", "to love", and "to be one with". The word rapidly became common parlance among science fiction fans, hippies, and later computer programmers and hackers, and has since entered the Oxford English Dictionary.

Fair Witness

The profession of Fair Witness, invented for the novel, has been cited in such varied contexts as environmentalism, psychology, technology, digital signatures, and science, as well as in books on leadership and Sufism. A Fair Witness is an individual trained to observe events and report exactly what is seen and heard, making no extrapolations or assumptions. While wearing the Fair Witness uniform of a white robe, they are presumed to be observing and opining in their professional capacity. Works that refer to the Fair Witness emphasize the profession's impartiality, integrity, objectivity, and reliability.

An example from the book illustrates the role of Fair Witness when Anne is asked what color a house is. She answers, "It's white on this side." The character Jubal then explains, "You see? It doesn’t occur to Anne to infer that the other side is white, too. All the King’s horses couldn’t force her to commit herself... unless she went there and looked – and even then she wouldn’t assume that it stayed white after she left.”

Waterbed

Stranger in a Strange Land contains an early description of the waterbed, an invention that made its real-world debut in 1968. Charles Hall, who brought a waterbed design to the United States Patent Office, was refused a patent on the grounds that Heinlein's descriptions in Stranger in a Strange Land and another novel, Double Star (1956), constituted prior art.

In popular culture

  • Leon Russell and the Shelter People features a song titled "Stranger in a Strange Land" with lyrics that describe ideas from the novel, sometimes narrated by Valentine's perspective, other times in a 3rd person.

Publication history

Two major versions of this book exist:

  • The 1961 version which, at the publisher's request, Heinlein cut by 25% in length. Approximately 60,000 words were removed from the original manuscript, including some sharp criticism of American attitudes toward sex and religion. The book was marketed to a mainstream readership, and was the first science fiction novel to be listed on The New York Times Best Seller list for fiction. By 1997, over 100,000 copies of the hardback edition had been sold along with nearly five million copies of the paperback. None of his later novels would match this level of success.
  • The 1991 version, retrieved from Heinlein's archives in the University of California, Santa Cruz, Special Collections Department by Heinlein's widow, Virginia, and published posthumously, which reproduces the original manuscript and restores all cuts. It came about because in 1989, Virginia renewed the copyright to Stranger and cancelled the existing publication contracts in accordance with the Copyright Act of 1976. Both Heinlein's agent and his publisher (which had new senior editors) agreed that the uncut version was better: readers are used to longer books, and what was seen as objectionable in 1961 was no longer so 30 years later.

Heinlein himself remarked in a letter he wrote to Oberon Zell-Ravenheart in 1972 that he thought his shorter, edited version was better. He wrote, "SISL was never censored by anyone in any fashion. The first draft was nearly twice as long as the published version. I cut it myself to bring it down to a commercial length. But I did not leave out anything of any importance; I simply trimmed all possible excess verbiage. Perhaps you have noticed that it reads "fast" despite its length; that is why. ... The original, longest version of SISL ... is really not worth your trouble, as it is the same story throughout—simply not as well told. With it is the brushpenned version which shows exactly what was cut out—nothing worth reading, that is. I learned to write for pulp magazines, in which one was paid by the yard rather than by the package; it was not until I started writing for the Saturday Evening Post that I learned the virtue of brevity."

Additionally, since Heinlein added material while he was editing the manuscript for the commercial release, the 1991 publication of the original manuscript is missing some material that was in the novel when it was first published.

The Foundation series is a science fiction book series written by American author Isaac Asimov. First published as a series of short stories in 1942–50, and subsequently in three collections in 1951–53, for thirty years the series was a trilogy: Foundation, Foundation and Empire, and Second Foundation. It won the one-time Hugo Award for "Best All-Time Series" in 1966. Asimov began adding new volumes in 1981, with two sequels: Foundation's Edge and Foundation and Earth, and two prequels: Prelude to Foundation and Forward the Foundation. The additions made reference to events in Asimov's Robot and Empire series, indicating that they also were set in the same fictional universe.

The premise of the stories is that, in the waning days of a future Galactic Empire, the mathematician Hari Seldon spends his life developing a theory of psychohistory, a new and effective mathematical sociology. Using statistical laws of mass action, it can predict the future of large populations. Seldon foresees the imminent fall of the Empire, which encompasses the entire Milky Way, and a Dark Age lasting 30,000 years before a second empire arises. Although the inertia of the Empire's fall is too great to stop, Seldon devises a plan by which "the onrushing mass of events must be deflected just a little" to eventually limit this interregnum to just one thousand years. To implement his plan, Seldon creates the Foundations—two groups of scientists and engineers settled at opposite ends of the galaxy—to preserve the spirit of science and civilization, and thus become the cornerstones of the new galactic empire.

One key feature of Seldon's theory, which has proved influential in real-world social science, is the uncertainty principle of sociology: if a population gains knowledge of its predicted behavior, its self-aware collective actions become unpredictable.

Publication history

Original stories

The original trilogy of novels collected a series of eight short stories published in Astounding Magazine between May 1942 and January 1950. According to Asimov, the premise was based on ideas in Edward Gibbon's History of the Decline and Fall of the Roman Empire, and was invented spontaneously on his way to meet with editor John W. Campbell, with whom he developed the concepts of the collapse of the Galactic Empire, the civilization-preserving Foundations, and psychohistory. Asimov wrote these early stories in his West Philadelphia apartment when he worked at the Philadelphia Naval Yard.

Foundation trilogy

The first four stories were collected, along with a new introductory story, and published by Gnome Press in 1951 as Foundation. The later stories were published in pairs by Gnome as Foundation and Empire (1952) and Second Foundation (1953), resulting in the "Foundation Trilogy", as the series is still known.

Later sequels and prequels

In 1981, Asimov was persuaded by his publishers to write a fourth book, which became Foundation's Edge (1982).

Four years later, Asimov followed up with yet another sequel, Foundation and Earth (1986), which was followed by the prequels Prelude to Foundation (1988) and Forward the Foundation (1993), published after his death in 1992. During the two-year lapse between writing the sequels and prequels, Asimov had tied in his Foundation series with his various other series, creating a single unified universe. The basic link is mentioned in Foundation's Edge: an obscure myth about a first wave of space settlements with robots and then a second without. The idea is the one developed in Robots of Dawn, which, in addition to showing the way that the second wave of settlements was to be allowed, illustrates the benefits and shortcomings of the first wave of settlements and their so-called C/Fe (carbon/iron, signifying humans and robots together) culture. In this same book, the word psychohistory is used to describe the nascent idea of Seldon's work. Some of the drawbacks to this style of colonization, also called Spacer culture, are also exemplified by the events described all the way back in 1957's The Naked Sun.

The link between the Robot and Foundation universes was tightened by letting the robot R. Daneel Olivaw - originally introduced in The Caves of Steel - live on for tens of thousands of years and play a major role behind the scenes in both the Galactic Empire in its heyday and in the rise of the two Foundations to take its place.

Asimov's Foundation series novels

Note: This plot outline for the seven novels follows the series' in-universe chronology, which is not the order of publication. After many years as a trilogy comprising Foundation, Foundation and Empire, and Second Foundation, the series was expanded by two prequels and two sequels.

Prelude to Foundation (1988)

Prelude to Foundation opens on the planet Trantor, the empire's capital planet, the day after Hari Seldon has given a speech at a mathematics conference. Several parties become aware of the content of his speech (that using mathematical formulas, it may be possible to predict the future course of human history). Seldon is hounded by the Emperor and various employed thugs who are working surreptitiously, which forces him into exile. Over the course of the book, Seldon and Dors Venabili, a female companion and professor of history, are taken from location to location by Chetter Hummin who, under the guise of a reporter, introduces them to various Trantorian walks of life in his attempts to keep Seldon hidden from the Emperor. Throughout their adventures all over Trantor, Seldon continuously denies that psychohistory is a realistic science. Even if feasible, it may take several decades to develop. Hummin, however, is convinced that Seldon knows something, so he continuously presses him to work out a starting point to develop psychohistory. Eventually, after much traveling and introductions to various, diverse cultures on Trantor, Seldon realizes that using the entire known galaxy as a starting point is too overwhelming; he then decides to use Trantor as a model to work out the science, with a goal of later using the applied knowledge on the rest of the galaxy.

Forward the Foundation (1993)

Eight years after the events of Prelude, Seldon has worked out the science of psychohistory and has applied it on a galactic scale. His notability and fame increase and he is eventually promoted to First Minister to the Emperor. As the book progresses, Seldon loses those closest to him, including his wife, Dors Venabili, as his own health deteriorates into old age. Having worked his entire adult life to understand psychohistory, Seldon instructs his granddaughter, Wanda, to set up the Second Foundation.

Foundation (1951)

Called forth to stand trial on Trantor for allegations of treason (for foreshadowing the decline of the Galactic Empire), Seldon explains that his science of psychohistory foresees many alternatives, all of which result in the Galactic Empire eventually falling. If humanity follows its current path, the Empire will fall and 30,000 years of turmoil will overcome humanity before a second Empire arises. However, an alternative path allows for the intervening years to be only one thousand, if Seldon is allowed to collect the most intelligent minds and create a compendium of all human knowledge, entitled Encyclopedia Galactica. The board is still wary but allows Seldon to assemble whomever he needs, provided he and the "Encyclopedists" be exiled to a remote planet, Terminus. Seldon agrees to these terms – and also secretly establishes a second Foundation of which almost nothing is known, which he says is at the "opposite end" of the galaxy.

After fifty years on Terminus, and with Seldon now dead, the inhabitants find themselves in a crisis. With four powerful planets surrounding their own, the Encyclopedists have no defenses but their own intelligence. At the same time, a vault left by Seldon is due to automatically open. The vault reveals a pre-recorded hologram of Seldon, who informs the Encyclopedists that their entire reason for being on Terminus is a fraud, insofar as Seldon did not actually care whether or not an encyclopedia was created, only that the population was placed on Terminus and the events needed by his calculations were set in motion. In reality, the recording discloses, Terminus was set up to reduce the Dark Ages from 30,000 years to just one millennium, based on following his calculations. It will develop by facing intermittent and extreme "crises" – known as "Seldon Crises" – which the laws governing psychohistory show will inevitably be overcome, simply because human nature will cause events to fall in particular ways which lead to the intended goal. The recording reveals that the present events are the first such crisis, reminds them that a second foundation was also formed at the "opposite end" of the galaxy, and then falls silent.

The Mayor of Terminus City, Salvor Hardin, proposes to play the planets against each other. His plan is a success; the Foundation remains untouched, and he becomes the effective ruler. Meanwhile, the minds of the Foundation continue to develop newer and greater technologies which are smaller and more powerful than the Empire's equivalents. Using its scientific advantage, Terminus develops trade routes with nearby planets, eventually taking them over when its technology becomes a much-needed commodity. The interplanetary traders effectively become the new diplomats to other planets. One such trader, Hober Mallow, becomes powerful enough to challenge and win the office of Mayor and, by cutting off supplies to a nearby region, also succeeds in adding more planets to the Foundation's control.

Foundation and Empire (1952)

An ambitious general of the current Emperor of the Galaxy perceives the Foundation as a growing threat and orders an attack on it, using the Empire's still-mighty fleet of war vessels. The Emperor, initially supportive, becomes suspicious of his general's long-term motive for the attack, and recalls the fleet despite being close to victory. In spite of its undoubted inferiority in purely military terms, the Foundation emerges as the victor and the Empire itself is defeated. Seldon's hologram reappears in the vault on Terminus, and explains to the Foundation that this opening of the vault follows a conflict whose result was inevitable whatever might have been done – a weak Imperial navy could not have attacked them, while a strong navy would have shown itself by its successes to be a direct threat to the Emperor himself and been recalled.

A century later, an unknown outsider called the Mule has begun taking over planets at a rapid pace. The Foundation comes to realize, too late, that the Mule is unforeseen in Seldon's plan, and that the plan cannot have predicted any certainty of defeating him. Toran and Bayta Darell, accompanied by Ebling Mis – the Foundations's greatest psychologist – and a court jester named Magnifico familiar with the Mule, set out to Trantor to find the Second Foundation, hoping to bring an end to the Mule's reign. Mis studies furiously in the Great Library of Trantor to decipher the Second Foundation's location in order to visit it and seek their help. He is successful and also deduces that the Mule's success stems from his being a mutant who is able to change the emotions of others, a power he used to first instill fear in the inhabitants of his conquered planets, then to make his enemies devoutly loyal to him. Mis is murdered by Bayta Darell before he can reveal the location, she having realised that Magnifico is in fact the Mule and has been using his gifts to drive Mis forward in his research, so that he can learn the location himself and subjugate the Second Foundation. Dismayed at having made a mistake which allowed Bayta to see through his disguise, the Mule leaves Trantor to rule over his conquered planets while continuing his search.

Second Foundation (1953)

As the Mule comes closer to finding it, the mysterious Second Foundation comes briefly out of hiding to face the threat directly. It consists of the descendants of Seldon's psychohistorians. While the first Foundation has developed the physical sciences, the Second Foundation has been developing Seldon's mathematics and the Seldon Plan, along with their own use of mental sciences. The Second Foundation ultimately wears down the Mule, who returns to rule over his kingdom peacefully for the rest of his life, without any further thought of conquering the Second Foundation.

However, as a result, the first Foundation has learned something of the Second Foundation beyond the simple fact that it exists, and has some understanding of its role. This means their behavior will now be chosen in light of that knowledge, and not based on uninformed natural human behavior, which means their behavior will no longer be the natural responses required by the mathematics of the Seldon Plan. This places the Plan itself at great risk. In addition, the first Foundation starts to resentfully consider the other as a rival, and a small group secretly begins to develop equipment for detecting and blocking mental influence in order to detect members of the Second Foundation. After many attempts to infer the Second Foundation's whereabouts from the few clues available, the Foundation is led to believe the Second Foundation is located on Terminus (the "opposite end of the galaxy" for a galaxy with a circular shape). The Foundation uncovers and destroys a group of fifty members of the Second Foundation and is left believing they have destroyed the Second Foundation. No longer concerned with the perceived threat, their behavior as a society will tend towards those anticipated by the Plan.

In fact the group of fifty were volunteers on Terminus whose role was to be captured and give the impression that they composed the whole of the Second Foundation, so that the Seldon Plan would be able to continue unimpeded. The Second Foundation itself, however, is finally revealed to be located on the former Imperial Homeworld of Trantor. The clue "at Star's End" was not a physical clue, but was instead based on an old saying, "All roads lead to Trantor, and that is where all stars end." Seldon, being a social scientist and not a physical one, placed the two Foundations at "opposite ends" of the galaxy, but in a sociological rather than physical sense. The first Foundation was located on the Periphery of the galaxy, where the Empire's influence was minimal; the Second Foundation was on Trantor, where, even in its dying days, the Empire's power and culture were strongest.

Foundation's Edge (1982)

Believing the Second Foundation still exists (despite the common belief that it has been extinguished), young politician Golan Trevize is sent into exile by the current Mayor of the Foundation, Harla Branno, to uncover the Second Foundation; Trevize is accompanied by a scholar named Janov Pelorat. The reason for their belief is that, despite the unforeseeable impact of the Mule, the Seldon Plan still appears to be proceeding in accordance with the statements of Seldon's hologram, suggesting that the Second Foundation still exists and is secretly intervening to bring the plan back on course. After a few conversations with Pelorat, Trevize comes to believe that a mythical planet called Earth may hold the secret to the location. No such planet exists in any database, yet several myths and legends all refer to it, and it is Trevize's belief that the planet is deliberately being kept hidden. Unknown to Trevize and Pelorat, Branno is tracking their ship so that, in the event they find the Second Foundation, the first Foundation can take military or other action.

Meanwhile, Stor Gendibal, a prominent member of the Second Foundation, discovers a simple local on Trantor who has had a very subtle alteration made to her mind, far more delicate than anything the Second Foundation can do. He concludes that a greater force of Mentalics must be active in the Galaxy. Following the events on Terminus, Gendibal endeavors to follow Trevize, reasoning that by doing so, he may find out who has altered the mind of the Trantor native.

Using the few scraps of reliable information within the various myths, Trevize and Pelorat discover a planet called Gaia which is inhabited solely by Mentalics, to such an extent that every organism and inanimate object on the planet shares a common mind. Both Branno and Gendibal, who have separately followed Trevize, also reach Gaia at the same time. Gaia reveals that it has engineered this situation because it wishes to do what is best for humanity but cannot be sure what is best. Trevize's purpose, faced with the leaders of both the First and Second Foundations and Gaia itself, is to be trusted to make the best decision among the three main alternatives for the future of the human race: the First Foundation's path, based on mastery of the physical world and its traditional political organization (i.e., Empire); the Second Foundation's path, based on mentalics and probable rule by an elite using mind control; or Gaia's path of absorption of the entire Galaxy into one shared, harmonious living entity in which all beings, and the galaxy itself, would be a part.

After Trevize makes his decision for Gaia's path, the intellect of Gaia adjusts both Branno's and Gendibal's minds so that each believes he or she has succeeded in a significant task. (Branno believes she has successfully negotiated a treaty tying Sayshell to the Foundation, and Gendibal – now leader of the Second Foundation – believes that the Second Foundation is victorious and should continue as normal.) Trevize remains, but is uncertain as to why he is "sure" that Gaia is the correct outcome for the future.

Foundation and Earth (1986)

Still uncertain about his decision, Trevize continues on with the search for Earth along with Pelorat and a local of Gaia, advanced in Mentalics, known as Blissenobiarella (usually referred to simply as Bliss). Eventually, Trevize finds three sets of coordinates which are very old. Adjusting them for time, he realizes that his ship's computer does not list any planet in the vicinity of the coordinates. When he physically visits the locations, he rediscovers the forgotten Spacer worlds of Aurora, Solaria, and finally Melpomenia. After searching and facing different dilemmas on each planet, Trevize still has not discovered any answers.

Aurora and Melpomenia are long deserted, but Solaria contains a small population which is extremely advanced in the field of Mentalics. When the lives of the group are threatened, Bliss uses her abilities (and the shared intellect of Gaia) to destroy the Solarian who is about to kill them. This leaves behind a small child who will be put to death if left alone, so Bliss makes the decision to keep the child as they quickly escape the planet.

Eventually, Trevize discovers Earth, but it, again, contains no satisfactory answers for him (it is also long-since deserted). However, it dawns on Trevize that the answer may not be on Earth, but on Earth's satellite – the Moon. Upon approaching the planet, they are drawn inside the Moon's core, where they meet a robot named R. Daneel Olivaw.

Olivaw explains that he has been instrumental in guiding human history for thousands of years, having provided the impetus for Seldon to create psychohistory and also the creation of Gaia, but is now close to the end of his ability to maintain himself and will shortly cease to function. Despite replacing his positronic brain (which contains 20,000 years of memories), he is going to die shortly. He explains that no further robotic brain can be devised to replace his current one, or which will let him continue assisting for the benefit of humanity. However, some additional time can be won to ensure the long term benefit of humanity by merging R. Daneel Olivaw's mind with the organic intellect of a human – in this case, the intellect of the child that the group rescued on Solaria.

Once again, Trevize is put in the position of deciding if having Olivaw meld with the child's superior intellect would be in the best interests of the galaxy. The decision is left ambiguous (though likely a "yes") as it is implied that the melding of the minds may be to the child's benefit, but that she may have sinister intentions.

Development and themes

The early stories were inspired by Edward Gibbon's The History of the Decline and Fall of the Roman Empire. The plot of the series focuses on the growth and reach of the Foundation, against a backdrop of the "decline and fall of the Galactic Empire." The themes of Asimov's stories were also influenced by the political tendency in SF fandom, associated with the Futurians, known as Michelism.

The focus of the books is the trends through which a civilization might progress, specifically seeking to analyze their progress, using history as a precedent. Although many science fiction novels such as Nineteen Eighty-Four or Fahrenheit 451 do this, their focus is upon how current trends in society might come to fruition and they act as a moral allegory of the modern world. The Foundation series, on the other hand, looks at the trends in a wider scope, dealing with societal evolution and adaptation rather than the human and cultural qualities at one point in time. In this he followed the model of Thucydides' work The History of the Peloponnesian War, as he once acknowledged.

Furthermore, the concept of psychohistory, which gives the events in the story a sense of rational fatalism, leaves little room for moralization. Hari Seldon himself hopes that his Plan will "reduce 30,000 years of Dark Ages and barbarism to a single millennium," a goal of exceptional moral gravity. Yet events within it are often treated as inevitable and necessary, rather than deviations from the greater good. For example, the Foundation slides gradually into oligarchy and dictatorship prior to the appearance of the galactic conqueror, known as the Mule, who was able to succeed through the random chance of a telepathic mutation. But, for the most part, the book treats the purpose of Seldon's plan as unquestionable, and that slide as being necessary in it, rather than mulling over whether the slide is, on the whole, positive or negative.

The books also wrestle with the idea of individualism. Hari Seldon's plan is often treated as an inevitable mechanism of society, a vast mindless mob mentality of quadrillions of humans across the galaxy. Many in the series struggle against it, only to fail. However, the plan itself is reliant upon the cunning of individuals such as Salvor Hardin and Hober Mallow to make wise decisions that capitalize on the trends. On the other hand, the Mule, a single individual with mental powers, topples the Foundation and nearly destroys the Seldon plan with his special, unforeseen abilities. To repair the damage the Mule inflicts, the Second Foundation deploys a plan which turns upon individual reactions. Psychohistory is based on group trends and cannot predict with sufficient accuracy the effects of extraordinary, unforeseeable individuals, and as originally presented, the Second Foundation's purpose was to counter this flaw. Later novels would identify the Plan's uncertainties that remained at Seldon's death as the primary reason for the existence of the Second Foundation, which (unlike the First) had retained the capacity to research and further develop psychohistory.

Asimov tried to end the series with Second Foundation. However, because of the predicted thousand years until the rise of the next Empire (of which only a few hundred had elapsed), the series lacked a sense of closure. For decades, fans pressured him to write a sequel. In 1982, after a 30-year hiatus, Asimov gave in and wrote what was at the time a fourth volume: Foundation's Edge. This was followed shortly thereafter by Foundation and Earth. This novel, which takes place some 500 years after Seldon, ties up all the loose ends and ties all his Robot, Empire, and Foundation novels into a single story. He also opens a brand new line of thought in the last dozen pages regarding Galaxia, a galaxy inhabited by a single collective mind. This concept was never explored further. According to his widow Janet Asimov (in her biography of Isaac, It's Been a Good Life), he had no idea how to continue after Foundation and Earth, so he started writing the prequels.

Asimov's imprecise future history

Asimov (right) was inspired by the Future History stories of Heinlein (left), but self-consciously wrote that his was "not the beautiful job that Heinlein did, but was actually made up 'ad hoc'".

In the spring of 1955, Asimov published a future history of humanity in the pages of Thrilling Wonder Stories magazine based upon his thought processes concerning the Foundation universe at that point in his life. According to the publication, "the scheme was not originally worked out as a consistent pattern and only includes about one-quarter of his total writings". Because of this, the dating in the foundation series is approximate and inconsistent.

Asimov estimates that his Foundation series takes place nearly 50,000 years into the future, with Hari Seldon born in 47,000 CE. Around this time, the future emperor Cleon I is born in the imperial capital Trantor, 78 years before the Foundation Era (FE) and the events of the original Foundation trilogy. After Cleon inherits the crown, the mathematician Hari Seldon comes to Trantor from Helicon to deliver his theory of psychohistory that predicts the fall of the empire, which triggers the events of Prelude to Foundation. Forward the Foundation picks up the story a few years later, with the emperor being assassinated and Seldon retiring from politics.

At the start of the Foundation Era, the events of the original Foundation novel (first published in Astounding Science Fiction as a series of short stories) take place, and the in-universe Foundation Era truly begins. According to Asimov, he intended this to take place around the year 47000 CE, with the Empire in decay as it battles the rising Foundation, who emerges as the dominant power a few centuries later. Thus begins the events of the Foundation and Empire, which include the unpredicted rise of the Mule, who defeats the Foundation thanks to his mutant abilities. The events of Second Foundation chronicle the titular Second Foundation's search and defeat of the Mule, and their conflict with the remnants of the original Foundation, averting the Dark Age. Asimov estimates that the Mule rises and falls somewhere around 47300 CE.

Foundation's Edge takes place 500 years after the establishment of the Foundation, outside of the original trilogy of novels. Foundation and Earth follows immediately after, with humanity choosing and justifying a third path distinct from the opposing visions of the two Foundations. According to Asimov, the Second Galactic Empire is established 48000 CE, 1000 years after the events of the first novel.

Asimov himself commented that his fiction's internal history was "actually made up ad hoc. My cross-references in the novels are thrown in as they occur to me and did not come from a systemized history. ... If some reader checks my stories carefully and finds that my dating is internally inconsistent, I can only say I'm not surprised."

Cultural impact

Impact in nonfiction

In Learned Optimism, psychologist Martin Seligman identifies the Foundation series as one of the most important influences in his professional life, because of the possibility of predictive sociology based on psychological principles. He also lays claim to the first successful prediction of a major historical (sociological) event, in the 1988 US elections, and he specifically attributes this to a psychological principle.

In his 1996 book To Renew America, U. S. House Speaker Newt Gingrich wrote that he was influenced by reading the Foundation trilogy in high school.

Paul Krugman, winner of the 2008 Nobel Memorial Prize in Economic Sciences, credits the Foundation series with turning his mind to economics, as the closest existing science to psychohistory.

The businessman and entrepreneur Elon Musk counts the series among the inspirations for his career. When Musk's Tesla Roadster was launched into space on the maiden flight of the Falcon Heavy rocket in February 2018, amongst other items it carried a 5D optical data storage copy of the Foundation series.

Stating that it "offers a useful summary of some of the dynamics of far-flung imperial Rome", Carl Sagan in 1978 listed the Foundation series as an example of how science fiction "can convey bits and pieces, hints and phrases, of knowledge unknown or inaccessible to the reader". In the nonfiction PBS series Cosmos: A Personal Voyage, Sagan referred to an Encyclopedia Galactica in the episodes "Encyclopaedia Galactica" and "Who Speaks for Earth".

Awards

In 1966, the Foundation trilogy beat several other science fiction and fantasy series to receive a special Hugo Award for "Best All-Time Series". The runners-up for the award were the Barsoom series by Edgar Rice Burroughs, the Future History series by Robert A. Heinlein, the Lensman series by Edward E. Smith and The Lord of the Rings by J. R. R. Tolkien. The Foundation series was the only series so honored until the establishment of the "Best Series" category in 2017. Asimov himself wrote that he assumed the one-time award had been created to honor The Lord of the Rings, and he was amazed when his work won.

The series has won three other Hugo Awards. Foundation's Edge won Best Novel in 1983, and was a bestseller for almost a year. Retrospective Hugo Awards were given in 1996 and 2018 for, respectively, "The Mule" (the major part of Foundation and Empire) for Best Novel (1946) and "Foundation" (the first story written for the series, and second chapter of the first novel) for Best Short Story (1943).

Impact in fiction and entertainment

Science fiction parodies, such as Douglas Adams' The Hitchhiker's Guide to the Galaxy and Harry Harrison's Bill, the Galactic Hero, often display clear Foundation influences. For instance, "The Guide" of the former is a spoof of the Encyclopedia Galactica, and the series actually mentions the encyclopedia by name, remarking that it is rather "dry", and consequently sells fewer copies than the guide; the latter also features the ultra-urbanized Imperial planet Helior, often parodying the logistics such a planet-city would require, but that Asimov's novel downplays when describing Trantor.

The 1957 short story Marius, which set off Poul Anderson's early future history, the Psychotechnic League, clearly shows the influence of Asimov's Foundation—though moved from the far future of a collapsing Galactic Empire to a near future of a late 20th Century Earth struggling to recover from the devastation of a nuclear Third World War. In this situation, the Finnish Professor Valti starts the science of Psychodynamics, which makes it possible to mathematically predict the future, and The Psychotechnic Institute makes use of Valti's formulas to subtly "guide" and manipulate the emerging world government. The similarity to Seldon and the Foundation is obvious, nor did Anderson try to hide it.

Frank Herbert also wrote Dune as a counterpoint to Foundation. Tim O'Reilly in his monograph on Herbert wrote that "Dune is clearly a commentary on the Foundation trilogy. Herbert has taken a look at the same imaginative situation that provoked Asimov's classic—the decay of a galactic empire—and restated it in a way that draws on different assumptions and suggests radically different conclusions. The twist he has introduced into Dune is that the Mule, not the Foundation, is his hero."

In 1995, Donald Kingsbury wrote "Historical Crisis", which he later expanded into a novel, Psychohistorical Crisis. It takes place about 2,000 years after Foundation, after the founding of the Second Galactic Empire. It is set in the same fictional universe as the Foundation series, in considerable detail, but with virtually all Foundation-specific names either changed (e.g., Kalgan becomes Lakgan), or avoided (psychohistory is created by an unnamed, but often-referenced Founder). The novel explores the ideas of psychohistory in a number of new directions, inspired by more recent developments in mathematics and computer science, as well as by new ideas in science fiction itself.

In 1998, the novel Spectre (part of the Shatnerverse series) by William Shatner and Judith and Garfield Reeves-Stevens states that the Mirror Universe divergent path has been studied by the Seldon Psychohistory Institute.

The oboe-like holophonor in Matt Groening's animated television series Futurama is based directly upon the "Visi-Sonor" which Magnifico plays in Foundation and Empire. The "Visi-Sonor" is also mirrored in an episode of Special Unit 2, where a child's television character plays an instrument that induces mind control over children.

During the 2006–2007 Marvel Comics Civil War crossover storyline, in Fantastic Four #542 Mister Fantastic revealed his own attempt to develop psychohistory, saying he was inspired after reading the Foundation series.

According to lead singer Ian Gillan, the hard rock band Deep Purple's song The Mule is based on the Foundation character: "Yes, The Mule was inspired by Asimov. It's been a while but I'm sure you've made the right connection... Asimov was required reading in the 60's."

Adaptations

Radio

An eight-part radio adaptation of the original trilogy, with sound design by the BBC Radiophonic Workshop, was broadcast on BBC Radio 4 in 1973—one of the first BBC radio drama serials to be made in stereo. A BBC 7 rerun commenced in July 2003.

Adapted by Patrick Tull (episodes 1 to 4) and Mike Stott (episodes 5 to 8), the dramatisation was directed by David Cain and starred William Eedle as Hari Seldon, with Geoffrey Beevers as Gaal Dornick, Lee Montague as Salvor Hardin, Julian Glover as Hober Mallow, Dinsdale Landen as Bel Riose, Maurice Denham as Ebling Mis and Prunella Scales as Lady Callia.

Film

By 1998, New Line Cinema had spent $1.5 million developing a film version of the Foundation Trilogy. The failure to develop a new franchise was partly a reason the studio signed on to produce The Lord of the Rings film trilogy.

On July 29, 2008, New Line Cinema co-founders Bob Shaye and Michael Lynne were reported to have been signed on to produce an adaptation of the trilogy by their company Unique Pictures for Warner Brothers. However, Columbia Pictures (Sony) successfully bid for the screen rights on January 15, 2009, and then contracted Roland Emmerich to direct and produce. Michael Wimer was named as co-producer. Two years later, the studio hired Dante Harper to adapt the books. This project failed to materialize and HBO acquired the rights when they became available in 2014.

Television

In November 2014, TheWrap reported that Jonathan Nolan was writing and producing a TV series based on the Foundation Trilogy for HBO. Nolan confirmed his involvement at a Paley Center event on April 13, 2015.

In June 2017, Deadline reported that Skydance Media would produce a TV series. In August 2018 it was announced that Apple TV+ had commissioned a 10 episode straight-to-series order. However, on April 18, 2019, Josh Friedman left the project as co-writer and co-showrunner. This was apparently planned, with either Friedman or screenwriter David Goyer leaving and the other staying. On June 22, 2020, Apple CEO Tim Cook announced the series would be released in 2021. On 13 March 2020, Apple suspended all active filming on their shows due to the COVID-19 outbreak; filming resumed on October 6, 2020.

The series is filmed at Troy Studios, Limerick, Ireland and the budget was expected to be approximately $50 million. The first two episodes premiered on September 24, 2021. Metacritic gave the first season a weighted average score of 63 out of 100 based on 22 reviews, indicating "generally favorable reviews".

Books within the greater Foundation series

Merging with other series

The series is set in the same universe as Asimov's first published novel, Pebble in the Sky, although Foundation takes place about 10,000 years later. Pebble in the Sky became the basis for the Empire series. Then, at some unknown date (prior to writing Foundation's Edge) Asimov decided to merge the Foundation/Empire series with his Robot series. Thus, all three series are set in the same universe, giving them a combined length of 18 novels, and a total of about 1,500,000 words (see the List of books below). The merge also created a time-span of the series of around 20,000 years.

The stand-alone story Nemesis is also in the same continuity; being referenced in Forward the Foundation, where Hari Seldon refers to a twenty-thousand-year-old story of "a young woman that could communicate with an entire planet that circled a sun named Nemesis." Commentators noted that Nemesis contains barely disguised references to the Spacers and their calendar system, the Galactic Empire and even to Hari Seldon which seem to have been deliberately placed for the purpose of later integration into the Foundation universe.

Asimov's "Author's Note" in Prelude to Foundation

The foreword to Prelude to Foundation contains the chronological ordering of Asimov's science fiction books. Asimov stated that the books of his Robot, Empire, and Foundation series "offer a kind of history of the future, which is, perhaps, not completely consistent, since I did not plan consistency to begin with." Asimov also noted that the books in his list "were not written in the order in which (perhaps) they should be read". In the Author's Note, Asimov noted that there is room for a book between Robots and Empire and The Currents of Space, and that he could follow Foundation and Earth with additional volumes.

Forward the Foundation, Nemesis, and The Positronic Man do not appear in Asimov's list, as they were not yet published at the time, and the order of the Empire novels in Asimov's list is not entirely consistent with other lists. For example, the 1983 Ballantine Books printing of The Robots of Dawn lists the Empire novels as: The Stars, Like Dust, The Currents of Space, and Pebble in the Sky. Given that The Currents of Space includes Trantor and that The Stars, Like Dust does not, these two books possibly were accidentally reversed in Asimov's list.

Asimov's standalone novels set in the Foundation universe

While not mentioned in the "Author's Note" of Prelude to Foundation, the novels The End of Eternity (1955), Nemesis (1989), and The Positronic Man (1992) are related to the greater Foundation series.

The End of Eternity is vaguely referenced in Foundation's Edge, where a character mentions the Eternals, whose "task it was to choose a reality that would be most suitable to Humanity". (The End of Eternity also refers to a "Galactic Empire" within its story.) Asimov himself did not mention The End of Eternity in the series listing from Prelude to Foundation. As for Nemesis, it was written after Prelude to Foundation, but in the author's note Asimov explicitly states that the book is not part of the Foundation or Empire series, but that some day he might tie it to the others.

In Forward the Foundation, Hari Seldon refers to a 20-thousand-year-old story of "a young woman that could communicate with an entire planet that circled a sun named Nemesis", a reference to Nemesis. In Nemesis, the main colony is one of the Fifty Settlements, a collection of orbital colonies that form a state. The Fifty Settlements possibly were the basis for the fifty Spacer worlds in the Robot stories. The implication at the end of Nemesis that the inhabitants of the off-Earth colonies are splitting off from Earthbound humans could also be connected to a similar implication about the Spacers in Mark W. Tiedemann's Robot books. According to Alasdair Wilkins, in a discussion posted on Gizmodo, "Asimov absolutely loves weird, elliptical structures. All three of his non-robot/Foundation science fiction novels — The End of Eternity, The Gods Themselves, and Nemesis — leaned heavily on non-chronological narratives, and he does it with gusto in The Gods Themselves."

In The Robots of Dawn, Dr. Han Fastolfe briefly summarizes the story from The Positronic Man (1992) or "The Bicentennial Man" (1976) in a conversation with Elijah Baley.

Other authors contributing to the expanded series

Asimov's novels covered only 500 of the expected 1,000 years it would take for the Foundation to become a galactic empire. The novels written after Asimov did not continue the timeline but rather sought to fill in gaps in the earlier stories. The Foundation universe was once again revisited in 1989's Foundation's Friends, a collection of short stories written by many prominent science fiction authors of that time. Orson Scott Card's "The Originist" clarifies the founding of the Second Foundation shortly after Seldon's death; Harry Turtledove's "Trantor Falls" tells of the efforts by the Second Foundation to survive during the sacking of Trantor, the imperial capital and Second Foundation's home; and George Zebrowski's "Foundation's Conscience" is about the efforts of a historian to document Seldon's work following the rise of the Second Galactic Empire.

Also, shortly before his death in 1992, Asimov approved an outline for three novels by Roger MacBride Allen, known as the Caliban trilogy, set between Robots and Empire and the Empire series. The Caliban trilogy describes the terraforming of the Spacer world Inferno, a planet where an ecological crisis forces the Spacers to abandon many long-cherished parts of their culture. Allen's novels echo the uncertainties that Asimov's later books express about the Three Laws of Robotics, and in particular the way a thoroughly roboticized culture can degrade human initiative.

After Asimov's death and at the request of Janet Asimov and the Asimov estate's representative, Ralph Vicinanza approached Gregory Benford and asked him to write another Foundation story. He eventually agreed, and with Vicinanza and after speaking "to several authors about [the] project", formed a plan for a trilogy with "two hard SF writers broadly influenced by Asimov and of unchallenged technical ability: Greg Bear and David Brin." Foundation's Fear (1997) takes place chronologically between part one and part two of Asimov's second prequel novel, Forward the Foundation; Foundation and Chaos (1998) is set at the same time as the first chapter of Foundation, filling in background; Foundation's Triumph (1999) covers ground following the recording of the holographic messages to the Foundation, and ties together a number of loose ends. These books are now claimed by some to collectively be a "Second Foundation trilogy", although they are inserts into pre-existing prequels and some of the earlier Foundation storylines and not generally recognized as a new Trilogy.

In an epilogue to Foundation's Triumph, Brin noted he could imagine himself or a different author writing another sequel to add to Foundation's Triumph, feeling that Hari Seldon's story was not yet necessarily finished. He later published a possible start of such a book on his website.

More recently, the Asimov estate authorized publication of another trilogy of robot mysteries by Mark W. Tiedemann. These novels, which take place several years before Asimov's Robots and Empire, are Mirage (2000), Chimera (2001), and Aurora (2002). These were followed by yet another robot mystery, Alexander C. Irvine's Have Robot, Will Travel (2004), set five years after the Tiedemann trilogy.

In 2001, Donald Kingsbury published the novel Psychohistorical Crisis, set in the Foundation universe after the start of the Second Empire.

Novels by various authors (Isaac Asimov's Robot City, Robots and Aliens and Robots in Time series) are loosely connected to the Robot series, but contain many inconsistencies with Asimov's books, and are not generally considered part of the Foundation series.

In November 2009, the Isaac Asimov estate announced the publication of a prequel to I, Robot under the working title Robots and Chaos, the first volume in a prequel trilogy featuring Susan Calvin by fantasy author Mickey Zucker Reichert. The first book was published in November 2011 under the title I, Robot: To Protect, followed by I, Robot: To Obey in 2013 and I, Robot: To Preserve in 2016.
