The book expands upon his views of quantum mechanics and its implications for understanding reality. This interpretation, which he calls the multiverse hypothesis, is one of a four-strand Theory of Everything (TOE).[1]

The four strands

  1. Hugh Everett's many-worlds interpretation of quantum physics, "The first and most important of the four strands".
  2. Karl Popper's epistemology, especially its anti-inductivism and its requiring a realist (non-instrumental) interpretation of scientific theories, and its emphasis on taking seriously those bold conjectures that resist being falsified.
  3. Alan Turing's theory of computation, especially as developed in Deutsch's "Turing principle", where Turing's Universal Turing machine is replaced by Deutsch's universal quantum computer. ("The theory of computation is now the quantum theory of computation.")
  4. Richard Dawkins's refinement of Darwinian evolutionary theory and the modern evolutionary synthesis, especially the ideas of replicator and meme as they integrate with Popperian problem-solving (the epistemological strand).

Deutsch's TOE

His theory of everything is (weakly) emergentist rather than reductive. It aims not at the reduction of everything to particle physics, but rather at mutual support among multiverse, computational, epistemological, and evolutionary principles.


Critical reception has been generally positive.[1][2][3][4] The New York Times wrote a mixed review for The Fabric of Reality, writing that it "is full of refreshingly oblique, provocative insights. But I came away from it with only the mushiest sense of how the strands in Deutsch's tapestry hang together."[5] The Guardian was more favorable in their review, stating "This is a deep and ambitious book and there were plenty of moments when I was out of my depth (the Platonic dialogue between Deutsch and a Crypto-inductivist left me with a pronounced sinking feeling). But the sheer adventure of thinking not just out of the envelope but right out of the Newtonian universe is exhilarating."[6]

A Night in the Lonesome October

A Night in the Lonesome October is a novel by American writer Roger Zelazny published in 1993, near the end of his life. It was his last book, and one of his five personal favorites.The book is divided in 32 chapters, each representing one "night" in the month of October (plus one "introductory" chapter). The story is told in the first-person, akin to journal entries. Throughout, 33 full-page illustrations by Gahan Wilson (one per chapter, plus one on the inside back cover) punctuate a tale heavily influenced by H. P. Lovecraft. The title is a line from Edgar Allan Poe's "Ulalume" and Zelazny thanks him as well as others – Mary Shelley, Bram Stoker, Sir Arthur Conan Doyle, Robert Bloch and Albert Payson Terhune – whose most famous characters appear in the book.

A Night in the Lonesome October was nominated for the Nebula Award for Best Novel in 1994.

A similar theme of conflict surrounding the opening of a gate to another world exists in Zelazny's novel Madwand.

Adjustment Team

"Adjustment Team" is a science fiction short story by American writer Philip K. Dick. It was first published in Orbit Science Fiction (September–October 1954, No. 4) with illustration by Faragasso. It was later reprinted in The Sands of Mars and Other Stories (Australian) in 1958, The Book of Philip K. Dick in 1973, The Turning Wheel and Other Stories (United Kingdom) in 1977, The Collected Stories of Philip K. Dick in 1987 (Underwood–Miller), 1988 (Gollancz, United Kingdom), 1990 (Citadel Twilight, United States), Selected Stories of Philip K. Dick in 2002 and in The Early Work of Philip K. Dick, Volume One: The Variable Man & Other Stories in 2009.

"Adjustment Team" served as the basis for the 2011 film The Adjustment Bureau.

Asgard (comics)

Asgard is a fictional realm and its capital city appearing in American comic books published by Marvel Comics. Based on the realm of the same name from Norse mythology, Asgard is home to the Asgardians and other beings adapted from Norse mythology. Asgard first appeared in Journey into Mystery #83 (October 1962) by Stan Lee, Larry Lieber and Jack Kirby, and features prominently in stories that follow the Marvel Comics superhero Thor.

Asgard has appeared in various media adaptations of Thor, including the 2011 Marvel Cinematic Universe film Thor, its 2013 sequel Thor: The Dark World, the 2015 film Avengers: Age of Ultron, and the 2017 Thor sequel Thor: Ragnarok.

Church–Turing–Deutsch principle

In computer science and quantum physics, the Church–Turing–Deutsch principle (CTD principle) is a stronger, physical form of the Church–Turing thesis formulated by David Deutsch in 1985.

David Deutsch

David Elieser Deutsch (; born 18 May 1953) is a British physicist at the University of Oxford. He is a Visiting Professor in the Department of Atomic and Laser Physics at the Centre for Quantum Computation (CQC) in the Clarendon Laboratory of the University of Oxford. He pioneered the field of quantum computation by formulating a description for a quantum Turing machine, as well as specifying an algorithm designed to run on a quantum computer. He is a proponent of the many-worlds interpretation of quantum mechanics.In 2009 Deutsch expounded a new criterion for scientific explanation, which is to formulate invariants: 'State an explanation [publicly, so that it can be dated and verified by others later] that remains invariant [in the face of apparent change, new information, or unexpected conditions]'.

A bad explanation is easy to vary. —David Deutsch

The search for hard to vary explanations is the origin of all progress. —David Deutsch

That "the truth consists of hard to vary assertions about reality" is the most important fact about the physical world. —David Deutsch

David Ramsay Steele

David Ramsay Steele is the author of Orwell Your Orwell: A Worldview on the Slab (a study of George Orwell's beliefs), Atheism Explained: From Folly to Philosophy (a popular exposition of atheism), and From Marx to Mises: Post-Capitalist Society and the Challenge of Economic Calculation (an exposition of the economic calculation problem). Since 1985 he has been Editorial Director of Open Court Publishing Company. With Michael R. Edelstein, in 1997 he co-wrote Three Minute Therapy: Change Your Thinking, Change Your Life, a psychological self-help book based on Albert Ellis's rational emotive behavior therapy and with Michael R. Edelstein and Richard K. Kujoth, in 2013 he co-wrote Therapy Breakthrough: Why Some Psychotherapies Work Better than Others, a study of cognitive-behavioral therapy arguing for its superiority to psychodynamic therapy.

From 1963 to 1973, Steele was a member of the Socialist Party of Great Britain.

In 1970 he became aware of the historical debate over economic calculation, and between 1970 and 1973 underwent an intellectual conversion from SPGB Marxism to libertarianism. He later co-founded the Libertarian Alliance and in 1982 would be identified with one of the two factions that resulted in the split of the group.

Digital physics

In physics and cosmology, digital physics is a collection of theoretical perspectives based on the premise that the universe is describable by information. It is a form of digital ontology about the physical reality. According to this theory, the universe can be conceived of as either the output of a deterministic or probabilistic computer program, a vast, digital computation device, or mathematically isomorphic to such a device.

Elizabeth (BioShock)

Elizabeth is a fictional character in Irrational Games' BioShock Infinite, the third title in the BioShock series. The game is set in 1912 on a floating steampunk city named Columbia which was founded on the principles of American exceptionalism. Elizabeth has been groomed in a controlled environment to take over the reins of the city once its current leader, Father Comstock, dies. Elizabeth has the power to open "tears" in the fabric of reality, allowing her to access parallel universes. To prevent her from leaving Columbia, her captors employ a "siphon" which drains and limits her powers, and she is locked in a tower guarded by a giant mechanical bird called the Songbird. The main protagonist of the game, Booker DeWitt, enters Columbia in order to rescue Elizabeth in exchange for his gambling debts being forgiven. Elizabeth also appears in Burial at Sea, a film noir-inspired episodic downloadable content story set in the underwater city of Rapture. She takes on a femme fatale role and serves as the player character in the second episode.

The character is voiced by Courtnee Draper and her motion capture was provided by Heather Gordon. Irrational Games based Elizabeth's face on Anna Moleva, a Russian cosplayer, after the developers saw her incredibly accurate costume, and hired her to do live-action advertisements. Elizabeth's relationship with Songbird was partly based on Ken Levine's personal experiences. She is slightly naive after having lived most of her life in a tower. Developers repeatedly considered simply cutting her due to the hassle in making her "work". Great work was put into her artificial intelligence, with the developers believing there had been no real great A.I. companion in video games since Half-Life 2's Alyx Vance. The character has hyper-realistic expressions to help players see her from across the battlefield, as well as a two-tone colour scheme and unique silhouette.

Elizabeth was heavily featured in news and media prior to the release of the game, and plastic figures of her have been made. She has been positively received, and Infinite reviews particularly highlighted her role. Her A.I. was praised, as was her character and narrative role.


Elminster Aumar, the Sage of Shadowdale, is a fictional character appearing in the Forgotten Realms campaign setting for the Dungeons & Dragons fantasy role-playing game. He is a powerful wizard featured in several novels by Forgotten Realms creator Ed Greenwood. Certain aspects of his appearance and demeanor seem to echo Gandalf, Merlin, or Odin.

Elminster was one of the first characters that Greenwood created for the Forgotten Realms. Information about him can be found in virtually all Forgotten Realms game products, but the novels in The Elminster Series are perhaps the most definitive sources of information. The series includes Elminster: The Making of a Mage, Elminster in Myth Drannor, The Temptation of Elminster, Elminster in Hell, and Elminster's Daughter.

House of M

"House of M" is a 2005 comic book storyline published by Marvel Comics. The storyline consists of a core eight-issue comic book limited series written by Brian Michael Bendis and illustrated by Olivier Coipel, and a number of crossover tie-in books. Its first issue debuted in June 2005 as a follow-up to the events of the "Planet X" and "Avengers Disassembled" storylines, in which the mutant superhero Scarlet Witch suffered a mental breakdown and tried to alter the fabric of reality to recreate her lost children. Scarlet Witch's father, Magneto, and her twin brother, Quicksilver, played major roles in the series. Like the 1995–1996 "Age of Apocalypse" storyline, "House of M" replaced the Earth-616 as the main reality for a brief time until Scarlet Witch reverts to normal. The events of the storyline were later indicated to have occurred on Earth-58163.

Joe and 30 Days of Night.


The multiverse is a hypothetical group of multiple universes including the universe in which we live. Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, and the physical laws and constants that describe them. The different universes within the multiverse are called "parallel universes", "other universes", or "alternate universes".

Simulated reality

Simulated reality is the hypothesis that reality could be simulated—for example by quantum computer simulation—to a degree indistinguishable from "true" reality. It could contain conscious minds which may or may not be fully aware that they are living inside a simulation. This is quite different from the current, technologically achievable concept of virtual reality. Virtual reality is easily distinguished from the experience of actuality; participants are never in doubt about the nature of what they experience. Simulated reality, by contrast, would be hard or impossible to separate from "true" reality. There has been much debate over this topic, ranging from philosophical discourse to practical applications in computing.
