Dans le futur, il est illégal de ne pas consommer, afin de faire circuler l'argent et soutenir l'économie, mais ils ont sinon le droit de faire à peu près ce que bon leur semble, tant que c'est monétisable. Les hologrammes publicitaires sont présents partout dans l'espace public et privé. Les gens regardent des publicités pour se détendre, et sont publiquement connus sous le nom de la marque qui sponsorise leur vie quotidienne. Toshiba est donc un policier chargé d'enquêter sur les citoyen soupçonnés par les algorithmes l'analyse de la consommation de frauder et de consommer moins que leur quota. Avec son collègue Walmart, ils soupçonnent un netrunner de frauder. Ils découvrent peu à peu que certains netrunners (qui ont une dérogation sur l'obligation de consommer tant qu'ils restent dans leurs mondes virtuels et utilisent des monnaies virtuelles) participent à un système compliqué de sociétés écrans qui permet de rediriger une partie de l'argent réel vers des fonds d'investissements offshore. Avec l'appui d'un netrunner qui s'oppose à ces fraudeurs qui ne respectent pas la pureté de leur éthique, ils découvrent que la personnalité simulée de Dany-Robert Dufour, un philosophe du passé, enseigne certains concepts à ces déviants et promettent qu'un grand évènement aura lieu sous peu. En même temps, Toshiba déprime, n'ayant pas de but dans la vie (comme devenir un surhumain alcoolique comme Walmart, ou netrunner, surhumain, cyborg, changer de sexe, adhérer à une religion…), et commence à se gaver de médicaments. Il meurt au cours de l'histoire, et est remplacé par un autre enquêteur aussi sponsorisé par Toshiba. À la fin, Walmart se fait passer pour un netrunner et reçoit l'information secrète proposée par le philosophe. Il s'agit d'un accès secret à un lieu virtuel, physiquement situé sur un tanker transformé en datacenter voguant dans les eaux internationales, où les « élus » peuvent perdre du temps, faire de la poésie… sans consommer et sans être poursuivi en justice.

In the BookWorld, the written Thursday struggles to keep the few readers of her books interested, after the remake of the BookWorld where the Great Library setting is replaced with an hollow planet setting where different genres are regions of islands, and books are organised geographically along streets in cities. Thursday also works for Jurisfiction's Accident Investigation Department and is asked to investigate the crash of a self-published book that was flown on its way to be destroyed after the last copy in the real word has been destroyed. She meets a strange character who tells her that ‘one of our Thursdays is missing’ and slips the real Thursday's Jurisfiction badge in her pocket before being arrested by the Men in Plaid, an independent militia obeying directly the Council of Genres. During her investigation, Thursday saves a mechanical man who becomes her butler and helps her discover that the accident may not have been an accident. Moreover, the real Thursday has not been seen for a long while and the written one starts to suspect that the disappearance is linked to the accident. Thursday decides to report that the accident was just an accident, but continues investigating on her own time. With Bradshaw's complicity, Thursday briefly visits the real world and meets Landen who confirms that the real Thursday has been missing for over a week. Upon her return she tries to find the taxi whose rear axle was found on the crash site and the taxi's driver, during which she survives multiple murder attempts by the Men in Plaid and the fact that the real Thursday was working with a geologist who got killed just before he could give any useful explanation. Thursday is then ordered by senator Jobsbworth to pose as the real one during the peace talks that are planned to take place a few days later in the North, in an attempt to prevent a war between Racy Novels and its two neighbours Women's Fiction and Dogma. A delegation travels up the Metaphoric River and discovers that there has been a terrible battle at the resupply station between a battalion of clowns from Comedy and an unknown opponent. During the remainder of the journey, Thursday discovers that Red Herring, her boss from JAID has been replaced by a double during the journey and has planted a bomb on the boat. She eventually figures out that Red Herring has learned that there is a large deposit of raw metaphor (a very valuable substance in the BookWorld) under Racy Novel and had manipulated the Daphne Farquitt genre to start a war, invade Racy Novel and take control of that deposit. Thursday then realises that the real Thursday may have survived the crash and be hiding somewhere in Psychological Thriller; she indeed finds her severely wounded but alive. In the end Thursday becomes a Jurisfiction agent and gets permission to change her books' story to mention the BookWorld and make them more interesting to the readers.

Fourteen years after Something Rotten Thursday is working for ACME carpets, which is a front for the now-defunct SpecOps 13 and 27; most of the members of the service are still working, funded by Thursday's operations on the cheese black market. But her work at the unofficial SpecOps is itself a front for her work at Jurisfiction. Over the past years, five books telling Thursday' adventures have been written. The first four have lots of sex and gratuitous violence, perpetrated by Thursday1-4. The fifth one is Thursday's attempt to take control and represent herself as she imagines herself, and Thursday5 is a soppy new-age fan. Thursday's current assignment is to train and evaluate Thursday1-4 and Thursday5 to become new Jurisfiction agents. The former is however too volatile to be trustworthy, and the second is too soft to make a good agent. In the meanwhile, Thursday also tries to convince her teenage son Friday to join the ChronoGuard, as he is supposed to become in the future the head of the organisation, but the boy is not interested at all. This is the source of tention, as the potential future Friday, head of ChronoGuard, explains that if the principle of the time machine is not invented within the next few days, time travel will not exist and all the work made by the ChronoGuard until now will be cancelled and some very influential members of ChronoGuard who have invested a lot of money with their knowledge of the future are really pushing to prevent this from happening. Thursday discovers, thanks to the phantom of her uncle Mycroft the inventor, that he had hidden the principle of time travel in a poem years ago, when he was hiding in the BookWorld, so it should be safe. In the meanwhile, the perspective of having no time left is causing people to lose interest in books and prefer reality television and the Council of Genres is planing to turn Jane Eyre into an interactive book that would change its story for good. Friday reveals that he is not the lazy teenager he has been pretending to be, but that it was just an act to prevent the discovery of time travel. Soon after Thursday is attacked in the real world by Thursday1-4 and loses the TravelGuide and therefore her ability to go to the BookWorld and veto the CoG's plans. Aware that the Goliath Corporation as an almost ready means of travel to the BookWorld, she makes a deal with them, but she is betrayed and stranded, while the Goliath agent attempts to travel to the poem and recover Mycroft's invention. The agent is however killed and Thursday destroys the invention. She is attacked by DanverClones and saved in the nick of time by Thursday5 disguised as Thursday1-4. Thursday rushes to the CoG to confront Thursday1-4 who has been pretending to be the real Thursday and approved all the stupid decisions from the CoG, but she eventually defeats Thursday1-4 while she was locked in Thursday5's book by destroying the said book.

After two years spent in the BookWorld as Jurisfiction's Bellman, Thursday returns to the real world, accompanied with her son Friday and Shakespeare's Hamlet. She discovers that the Whig party leader Yorrick Kayne (who has already caused some trouble earlier) is campaigning to become dictator of England (a fact confirmed by Thursday's time-travelling father who warns her that if the Swindon croquet team does not win the finals, Kayne will eventually cause a nuclear holocaust; the 13th century St Zvlkx, who has made remarkably accurate predictions in the past however predicts that Swindon will win the game). Kayne is very successfully misdirecting the population's attention to hating the Danes, who are accused to be the source of all of England's problems, ordering all Danish books to be destroyed. Equally surprising is the fact that the Goliath Corporation is transforming from a company into a faith organisation where customers would become followers; as part of the process they offer to repair all the damages they have caused in the past, allowing Thursday to ask Goliath to un-eradicate her husband Landen (which eventually happens, after a few cycles of him appearing and disappearing). In parallel, Thursday gets her job back at SpecOps (despite having been AWOL for two years) and promises she would find a way to hide several truckloads of books in Wales. The solution arises when she discovers that in order for Swindon to win the croquet game after Goliath, supporting Kayne, has scared off its best players, she needs the help of the genetically re-engineered neanderthals (who play croquet very well but are not at all interested in competition). The neanderthals, who cannot make children, accept on the condition that she helps them find their species' blueprints from the lab at the Welsh border where they had been created decades ago. The trip to Wales allows her to hide the books and secure the cooperation of the neanderthals for the croquet game. Thursday then confronts Kayne, and while she has failed to recover the self-published novel by a Danish author from which Kayne has escaped, the latter is transformed into a human during a duel with the Cheshire Cat and loses his inhuman ability of persuasion (which was amplified by the ovinator, an invention by Thursday's uncle Mycroft). The ovinator is destroyed by Hamlet just before the croquet game, which Swindon wins by a hair. Just at the end, Thursday is mortally wounded by the Minotaur who had escaped from the BookWorld two years ago under the action of an accomplice of Kayne's, but as she enters the Underworld, the assassin who had been paid by Kayne to kill her and had been mortally wounded in an accident decides to take her place. When she wakes up from her coma a few weeks later, she learns that St Zvlkx was a time traveller who had been placing bets on future events with England's oldest betting shop before reappearing in the present and dying in a road accident. The betting shop now must pay several billions of pounds in gains; being indirectly owned by Goliath, it forces the corporation to sell half of its shares to Zvlkx's sponsor.

Thursday hides from Aornis in a never published story stored in the Well of Lost Plots, the counterpart of the fiction world's library (where published books are stored) which preserves unpublished books. She discovers that books are actually created in the Well and the stories are simply sent to the mind of real-world authors whose role is only to write them down. The Well is filled with generic characters, plot devices, various imaginary creatures, as well as misspelling vyrus, grammasites and other creatures who affect the text, sometimes to the point where it becomes useless. Unpublished books are preserved for a limited time, before they are taken apart and their components reused in other books. As Aornis exists in Thursday's mind in the form of a mindworm, trying to destroy her personality one memory at a time, Thursday quickly forgets about her husband Landen; thankfully her Gran helps her fight the mindworm and recover her memories. At the same time, Thursday completes her training as a Jurisfiction agent with Mrs. Havisham and becomes a fully qualified junior agent. She investigates the suspicious deaths of two of her Jurisfiction colleagues and some time later of Mrs. Havisham herself. All had been investigating BOOK version 9 (a.k.a. UltraWord), the new operating system allowing the Well to produce stories, send them to authors, let the readers actually read the book. UltraWord is created and promoted by Text Grand Central, and Thursday eventually discovers that UltraWord will not only severely limit stories to a very bland form of description and narration, rendering most of the jobs in the Well redundant, but it also allows the technicians of Text Grand Central to rewrite at will any text without anyone noticing. She makes those revelations during the Annual BookWorld awards, where a majority of the BookWorld population is asked to vote for or against the use of UltraWord. Only the apparition of the Great Panjandrum, summoned by Thursday using the emergency button of her Jurisfiction TravelGuide allows for the vote to take place without interference from Text Grand Central. The Great Panjandrum also names Thursday to be the next Bellman, superintendent of Jurisfiction.

En vacances à Sète, Léo accepte d'enquêter sur la mort suspecte d'un ostréiculteur de l'étang de Thau.

An American submarine in the Pacific is transported from 1944 to the year 1,000,000. The crew meets a society of winged men who live in a city floating in the air, above a planet Earth mostly covered in water (brought several hundreds of thousands of years earlier by meteorites) where solid ground is not anymore solid and therefore unsuitable for building and living. They learn that the humans at the time water started to raise have designed two new species, winged men and fishmen who live in a city under water. The fishmen have access to natural resources and devices inherited from the original humans, and have decided to get rid of the winged men by attracting the flying city towards the water. The winged men, who have not access to natural resources and build no devices, have used a time-travel device to fetch war machines from various times in the past. The humans' submarine, equipped with explosive torpedoes, is the only one able to destroy the underwater city of the fishmen. All are promised to be sent back to their time once the city is destroyed. As the commander of the submarine has been taken by the fishmen and is presumed dead, the first officer is taken to the flying city to meet the “council”, an omniscient computer that shows him the lives of both the winged men and the fishmen. He is then returned to the submarine who has been taken over by warlike women from the year 10,000 who are in a hurry to go back to their time. But they do not know how to operate a diesel submarine, allowing the first officer to retake his ship and instead of destroying the whole city, only destroys its core that controls the devices inherited from the humans ancestors, putting the fishmen and winged men on equal footing. As promised, all are then returned to their own time.

Oksa rend alors visite à Dragomira et Abakoum sur l'île des Sans-Âge ; ces derniers lui révèlent que l'Égide se reformera à la naissance de ses enfants. Oksa et ses amis sortent alors une première fois pour rencontrer Mortimer à Londres et décider d'un plan. Ils sortent une deuxième fois pour infiltrer un sommet de chefs d'état et utilisent la magie pour leur imposer des idées de lutte contre la pollution. Malheureusement, Till, le demi-frère adolescent de Tugdual découvre par hasard l'existence de la brèche et Sol finit par obtenir cette information. Sol force alors le passage vers l'extérieur, blessant au passage les gardiens mis en place par Oksa, et peu après Till entraîne ses amis dans la brèche. Bien qu'elle soit sur le point l'accoucher, Oksa et ses amis partent à la recherche de Till, mais l'accouchement commence alors qu'elle est dans la brèche ; un des bébés est aspiré par l'Égide alors que cette dernière se reforme, et Oksa accouche du second à l'intérieur. Till, ses amis et le bébé se retrouvent bloqués à Caracas, en compagnie de personnes organisées en communauté autonome.

Following her success in The Eyre Affair, Thursday is forced to do PR for SpecOps, but she is prohibited to tell the truth about the role of Jack Schitt, the Goliath Corporation agent. She investigates the sudden discovery of a lost Shakespeare play that falls into the hands of the leader of the Whig party who uses it to increase his chances of becoming Prime Minister. Thursday's father also tells her that the World is going to end very soon, being entirely covered with an unknown pink substance. Over the course of several weeks, Thursday finds herself repeatedly in situations where an impossibly large number of coincidences almost succeed in getting her killed, while her hierarchy is trying to find an excuse to arrest her. Then one day she discovers that her husband Landen has been erased out of her history by corrupt chonoguards working for Schitt's half-brother Schitt-Hawse. The latter blackmails Thursday into freeing Schitt from the poem where he's kept prisoner. In the absence of her uncle who had invented the Prose Portal, the only way she knows to enter a story is Mrs Nakajima whom she had met in Jane Eyre. Thursday looks for her in Okinawa where she finds Nakajima's travel book, allowing her to travel on her own into a story. There she is chosen to become a member on Jurisfiction, an organization that ensures the stability of worlds of literary fiction. Thursday becomes an apprentice to Great Expectations' Mrs Havisham, one of the best Jurisfiction agents. After a failed attempt by her father to prevent Landen's death as a child, Thursday fetches Schitt and is kidnapped by Schitt-Hawse, but is rescued by Mrs Havisham. They then prove that the Shakespeare play was taken from Jurisfiction's library of lost books, and that the Whig politician is actually a fictional character, who is arrested too. She then discovers that the coincidences that almost got her killed have been provoked by Hades' sister Aornis who wants revenge for her brother's death, by putting Thursday in a situation where she would prevent the end of the world (by being covered in out-of-control, self-replicating Dream Topping, invented by her cousin) if she commits suicide. Thursday is saved in the nick of time by an old version of her father who takes the self-replicating stuff to the down of time, where it becomes the beginning of life on Earth. Thursday then goes into hiding into a book from the library of lost books.

In a parallel universe where England and Russia still fight in the Crimean war, Thursday Next is a LiteraTec investigator whose job is to fight crimes against literary art. Soon after the original manuscript for Dickens' Martin Chuzzlewit is stolen in London without the thieve having left any clue (not even on video-surveillance), Thursday is transferred to SpecOps 5 to advise an agent about Acheron Hades, a master criminal with the power to control minds and look like anyone. Having discovered that Hades has stolen the manuscript, she attempts to arrest Hades, but she is wounded and her colleagues are killed in the operation. After an investigation by SpecOps 1 who claims that Hades has died in a car accident, she sees her future self telling her to take the LiteraTec job in Swindon, her hometown. Upon her arrival she meets her family an especially her uncle Mycroft who shows her his new invention the Prose Portal, a device based on book worms that allow people to enter into literary works. Besides her new colleagues, she also meets Jack Schitt, a representative of the all-powerful Goliath corporation who recently promised a new plasma rifle that would end the Crimean war. Some time later, the manuscript for Jane Eyre is stolen by Hades, and Mortimer and his invention disappear. Hades demonstrates his power by removing a minor character from Martin Chuzzlewit, which causes all copies of the story get instantly modified. Thursday and her colleague travel to Haworth to investigate, but are delayed by a time distortion on the motorway which allows Thursday to talk to her past self. Thursday and her colleagues manage to track some of Goliath's associates, and they get a clue that the criminal is hiding in the People's Republic of Wales. Soon after, Hades kidnaps Jane Eyre and threatens to kill her unless he's paid a ransom. Schitt attempts to swindle the criminal who escapes again, and they track him to his hideout in Wales. There Thursday understands that Schitt wants to buy the Prose Portal from Hades to be able to get plasma rifles from a promotion book about plasma rifles, as in reality Goliath has been unable to develop the weapon. Convinced by Thursday to return Jane to her story, Hades goes into hiding in the story, quickly followed by Thursday, who spends there several months with Rochester, searching for Hades. They eventually find him and kill him, changing in the process the end of the story (that most people don't like) to turn it into the happily-ever-after version that exists in our universe.

Dans l'Urbs, Othon tente de convaincre ses anciens alliés de se joindre à lui, mais ceux-ci ont préféré s'allier au pouvoir en place, un triumvirat présidé par Vinius. Le triumvirat tente d'assassiner Plautine et Othon, et ces derniers ne doivent leur salut qu'à l'aide des hommes-chiens qui contrôlent maintenant la Nef d'Othon. Poursuivis par la flotte spatiale de l'Urbs, Plautine et Othon se rendent sur Mars tandis que la Nef et les hommes-chiens se cache sous la glace d'Europe. Dans les entrailles d'Olympus Mons, dans des installations autrefois habitées par les humains, les deux Intelligences rencontrent Plutarque, une Intelligence ancestrale qui a transformé tout le matériel abandonné par les humains en armes défensives, qu'Othon utilise avec succès pour repousser la flotte. En même temps Plautine apprend en rêves (révélant des informations cachées dans sa mémoire) que la maladie qui a fait disparaître les humains durant l'Hécatombe a été transmises par les noèmes dans leur tentative de protéger ces derniers, et que la création de Plautine est le fait de Vinius et d'une entité encore inconnue afin de manipuler les actions des humains sur le long terme dans le but de provoquer l'Hécatombe et la réception du message qui l'a sortie de son sommeil. Sur Europe, les hommes-chiens rencontrent des hommes-bélougas (créés peut-être par des humains) dont la société organisée en castes contrôle des mariages consanguins permettant d'éviter à un petit nombre la régression de leur intelligence. Refusant une telle solution à leur problème, ils repartent après la victoire d'Othon sur Mars, tous ensemble vers la planète à l'origine du message. Ils sont attaqués par Lacus, allié aux Barbares, qui les force à un atterrissage en catastrophe. Là, tandis que les hommes-chiens tentent de repousser les Barbares (une intelligence collective au corps pas vraiment tangible) ils rencontrent Achinus, la première Intelligence, émergée spontanément des réseaux informatiques des humains et qui avait disparu depuis longtemps. Achinus prend soin de la dernière humaine en stase dans un espace de non-temps, Bérénikè. Cette dernière, qui avait aussi disparu avant l'Hécatombe, révèle qu'elle en est l'instigatrice, et qu'elle compte maintenant avec Othon comme bras armé, conquérir la galaxie et recréer une humanité à son image. Plautine finit par déduire que l'Hécatombe était en fait une numérisation à grande échelle de l'humanité, et que les humains ne sont pas morts mais enfermés dans une sorte d'enfer, en attente d'être utilisé par Bérénikè. Plautine tue cette dernière par accident, mettant fin à ses machinations, et libérant Othon et elle-même du Carcan. Achinus transfère l'esprit Othon, à la demande de ce dernier, dans les milliards de milliards de nano-robots qui protégeaient la planète, et Othon, en deus ex machina sauve ses hommes-chiens de l'entité Barbare qui allait les massacrer. Plautine quant à elle part à la recherche des humains.

Dans un futur lointain, l'espèce humaine a disparu très rapidement suite à une épidémie d'origine incertaine, laissant derrière elle un nombre d'intelligences artificielles appelées noèmes. Au moins deux d'entre eux, appelés Plautine et Othon, ont développé un corps sous forme de gigantesque nef spatiale. Les noèmes étant programmés pour respecter les trois lois d'Asimov (surnommées le Carcan), ils attendent l'occasion de faire renaître l'espèce humaine. Dans l'intervalle, ils ont entouré la zone où les humains ont habité d'une ceinture où la vie est impossible, les Limes, pour empêcher d'autres espèces non-humaines, les Barbares, d'étendre leur territoire dans l'espace humain. Après deux mille ans d'attente, Plautine reçoit un mystérieux message qui la sort de son sommeil. Elle avait divisé son esprit en quatre entitées qui ont continué d'être actives durant son sommeil. L'une d'entre elles a construit un corps biologique avec un cerveau électronique pour contenir une partie de Plautine. Une autre a passé un accord secret avec les Barbares qui, parvenant enfin à franchir les Limes, attaquent la nef de Plautine et la détruisent. La seconde Plautine parvient à s'échapper et est recueillie par Othon (à qui Plautine avait envoyé un message au moment de son réveil). Elle découvre qu'Othon (qui au contraire de Plautine a son propre corps dont la nef n'est qu'un moyen de transport) a fabriqué une nouvelle espèce d'hommes-chiens qui le prennent pour leur dieu, et dont il s'est servi pour attaque les Barbares et sauver la seconde Plautine. Cette dernière leur parle alors du Carcan qui empêche Othon de leur faire le moindre mal, provoquant une révolte contre celui qui les a abusé depuis des siècles. Plautine apprend d'Othon que l'espèce des hommes-chiens est appelé à régresser en intelligence si de nouveaux individus, fabriqués avec une certaine intelligence, ne sont pas injéctés de force dans la population sous forme d'adpotion forcée et de mariages arrangés. Othon emmène alors Plautine (ainsi que les hommes-chiens de la nef) vers l'Urbs, où vivent les autres noèmes.

Depuis dix ans, Apolline et sa famille se rendent chaque année sur la tombe d'Henri Poincaré, conformément au testament de Théodore Folifou, leur arrière-grand-père. Pour la première fois, son petit frère Pierrot comprend le sens caché du testament, qui les mène à l'académie Olympia, fondée à l'origine par Einstein pour discuter du travail de Poincaré. Par la suite, cette académie est devenu un service secret ayant pour mission d'empêcher l'utilisation des découvertes scientifiques à des fins néfastes, surtout durant la guerre froide. Accompagnés de leur grand-mère, la fille de Folifou, ils sont invités à rejoindre les rangs de l'académie s'ils arrivent à résoudre des énigmes mathématiques dans la ville de Paris. Apolline est attaquée durant l'une des épreuve et on lui vole les énigmes de la journée, ce qui, à cause du règlement strict, met fin à leurs chances d'entrer à l'académie. Plusieurs mois plus tard, Pierrot découvre un nouvel indice dans le testament, ce qui met l'équipe sur les traces de l'agresseur d'Apolline. Un indice laissé par un des quatre membres actuels de l'académie les met sur la piste d'une mystérieuse cellule Babylone, dirigée par la mère d'Apolline. Cette dernière explique qu'avec l'explosion des découvert scientifiques et des technologies, l'académie Olympia avait perdu sa légitimité à décider seule de ce qui est bon ou mauvais et le rôle de la cellule était de laisser fuiter les informations vers le public afin que les décision soient prises par le peuple plutôt que par un petit comité. Le testament de Folifou et la résolution de ses énigmes marque la fusion de l'académie Olympia et de la cellule Babylone.

Les bactéries de l'intestin, essentiellement dans la fin du gros intestin, jouent un rôle majeur dans le fonctionnement de l'organisme, non seulement en transformant des aliments que l'intestin ne peut absorber directement, produisant ainsi des glucides, des lipides essentiels et des vitamines, mais aussi en produisant des hormones qui peuvent affecter l'humeur et la santé, tant du corps que de l'esprit. La bonne santé du microbiote intestinal permet d'éviter l'installation de bactéries nocives, et cette bonne santé dépend grandement de l'alimentation.

Étant données une probabilité a priori qu'une théorie est vraie et une observation, le théorème de Bayes permet de calculer une probabilté a posteriori qui prend en compte cette observation. Il permet donc d'affiner la crédence (un anglicisme, on devrait parler du « crédit accordé à ») d'une théorie, sa plausibilité, au vu des observations. Bien que simple, le théorème de Bayes à cependant un grand nombre d'applications même si des statisticiens célèbres l'ont par le passé honni parce qu'il fait appel à un a priori alors que la recherche d'objectivité en sciences devrait bannir tout a priori pour ne se concentrer que sur les faits. Dans la pratique cependant, un scientifique demandera un grand nombre de contre-exemples avant de rejeter une théorie fondamentale sur laquelle reposent un grand nombre d'autres théories et d'applications : il s'agit bien là d'un a priori, d'une crédence très élevée de cette théorie fondamentale.

Depuis ce temps, le bayesianisme a lentement fait sont entrée dans les sciences, en particulier dans les domaines de l'intelligence artificielle dont nombre de théories sont fondées sur le théorème de Bayes, et dans les sciences cognitives : il semblerait que cerveau soit une machine à faire des inférences bayesiennes. Étrange donc que lorsqu'on fait un raisonnement explicite, on ait tellement de mal à appliquer ledit théorème.

En dehors des cas très simples, le théorème de Bayes est impossible à appliquer, car il requiert de prendre en compte les crédences de toutes les théories alternatives à la théorie étudiée, et ceci est impossible. La complexité de Solomonoff (ou de Kolmogorov) d'une théorie étant définie comme la longueur minimale du programme informatique qui permet de calculer la crédence de cette théorie (en acceptant la thèse de Church-Turing selon laquelle tout l'univers peut être simulé par un machine de Turing universelle et un programme adéquat, et que toute théorie peut être représentée par une suite de bits selon la théorie de l'information de Shannon), certaines théories ont des complexités comparables à la taille de l'univers visible. Il est donc nécessaire de calculer des approximations des crédences de ces théories, et c'est ce que font le cerveau et certains algorithmes d'intelligence artificielle.
