It won the John W. Campbell Award for the best science-fiction novel of the year in and was nominated for the Philip K. Dick Award that same year.

The novel was also cited in a Scientific American article on multiverses by Max Tegmark. Permutation City deals with a question common in cyberpunk and postcyberpunk works: More specifically, Permutation City focuses on exploring one possible model of consciousness and reality, the Logic of the Dust Theory of reality, or simply Dust Theory , similar to the Ultimate Ensemble Mathematical Universe hypothesis proposed by Max Tegmark.

Like some other works of contemporary science fiction, it begins with the assumption that human consciousness is Turing computable: Specifically, the book deals with some possible consequences of human consciousness being amenable to mathematical manipulation, as well as some possible consequences of simulated realities.

In this way, Egan attempts to deconstruct not only some standard notions of self, memory, and mortality, but also of physical reality.

Over the course of the story, Egan gradually elaborates the Logic of the Dust Theory of reality, the implications of which form the premise for much of the story's intrigue.

The story explores these ideas through a variety of avenues. One is that of the Autoverse , an artificial life simulator ultimately based on a cellular automaton complex enough to represent the substratum of an artificial chemistry.

The Autoverse is a deterministic chemistry set, internally consistent and vaguely resembling real chemistry, but with only thirty-two elements and no nuclear analogue.

In the novel, tiny environments, simulated in the Autoverse and filled with small populations of a simple, designed lifeform, Autobacterium lamberti , are maintained by a dwindling community of enthusiasts obsessed with getting A.

Another venue for these explorations is VR, virtual realities making extensive use of patchwork heuristics to simulate, crudely , completely immersive and convincing physical environments, albeit at a maximum of seventeen times slower than "real" time, the limit to the optical crystal computing technology used at the time of the story.

Larger VR environments, covering a greater internal volume in greater detail, are cost prohibitive even though VR worlds are computed selectively for inhabitants, reducing redundancy and extraneous objects and places to the minimum details required to provide a convincing experience to those inhabitants, e.

Within the story, " Copies ", digital renderings of human brains with complete subjective consciousness, the technical descendants of ever more comprehensive medical simulations, live within VR environments after a process of "scanning".

Copies are the only objects within VR environments that are completely mathematically internally consistent, everything else being the product of varying levels of generalisation, lossy compression , and hashing at all times.

Copies form the conceptual spine of the story, and much of the plot deals directly with the "lived" experience of Copies, most of whom are the survivors of wealthy billionaires suffering terminal illnesses or fatal accidents, who spend their existences in VR worlds of their creating, usually maintained by trust funds which independently own and operate large computing resources for their sakes, separated physically and economically from most of the rest of the world's computing power, which is privatised as a fungible commodity.

In this way, Egan also deals with the socioeconomic realities of life as a Copy the global economy of the novel is in recession and Copies often lose their vital assets , many of the less wealthy of whom live in " the Slums ", a euphemism for the state of being bounced around the globe to the cheapest physical computing available at any given time in order to save money.

Many such lower-and-middle-class Copies exist at considerable "slowdown" relative to "real" time or even optimum Copy time, in order to save further money by allowing themselves to be computed momentarily from place to place and saved in suspension for cheap in the meantime.

Through this, the concept of solipsism is examined prominently, with many lower-and-middle-class Copies attending social functions called Slow Clubs, where socialising Copies agree to synchronise with the slowest person present.

Further Egan novels which deal with these issues from various other perspectives include Diaspora and Schild's Ladder.

The plot of Permutation City follows the lives of several people in a near future reality where the Earth is ravaged by the effects of climate change, the economy and culture are largely globalised the most commonly used denomination of currency is the ecu, from the word ecumen , a Greek root meaning 'the inhabited world' , and civilisation has accumulated vast amounts of ubiquitous computing power and memory which is distributed internationally and is traded in a public market called the QIPS Exchange QIPS from MIPS , where the Q is Quadrillions.

Most importantly, from the perspective of the story, this great computing capacity is used to construct physiological models of patients for medical purposes, reducing the need for actual medical experimentation and enabling personalised medical treatments, but also enabling the creation of Copies, whole brain emulations of "scanned" humans which are detailed enough to allow for subjective conscious experience on the part of the emulation.

Although not yet in widespread usage, scanning has become safe enough and common enough to allow for a subset of wealthy or dedicated humans to afford to create backups of themselves, generally with the intention of surviving the biological deaths of their bodies.

A minority of Copies exist, though they are largely perceived with some justification as being a collection of the thanatophobic eccentric rich.

Copies do not yet possess human rights under the laws of any nation or international body, although a subgroup of the wealthiest Copies, those still involved with their own estates or businesses, finance a powerful lobby and public relations effort to advance the Copy rights cause.

To this effect, the legal status of Copies is viewed as somewhat farcical even by sceptics of the cause, and many expect full Copy rights to be granted in Europe within two decades.

The plotline travels back and forth between the years of and , and deals with events surrounding the life of a Sydney man named Paul Durham, who is obsessed with experimenting on Copies of himself because he believes Copies of himself should be more willing to undergo experimentation.

In the latter time frame, Durham is revealed to be, apparently, a con artist of some type, who travels around the world visiting rich Copies and offering them prime real estate in some sort of advanced supercomputer which, according to his pitch, will never be shut down and will be powerful enough to support any number of Copies in VR environments of their own designing at no slowdown whatsoever, no matter how preposterously opulent those environments might be.

He pitches this concept to the Copies, predicated upon the prediction that the Copy rights movement might run into resistance due to devastating climate change.

As the world undergoes increasingly extreme and erratic weather, a variety of international bodies, especially the Association of Southeast Asian Nations , which has been particularly hard-hit by tropical storms, have proposed projects to use their vast computing resources to attempt to intervene, utilising chaotic effects to their advantage, in global weather patterns with such precision as to minimise weather-related destruction while also minimising the scale of the efforts necessary to do so.

Durham predicts this will clash with the spread of Copy rights, as both Copies and weather simulations will demand increasing QIPS Exchange shares in the future.

All that each Copy must do is to make the laughably small investment of two million ecus in order to bring Durham's fantasy computer into existence.

Please try again later. Just reading the back flap of this book doesn't even really begin to describe the depth of the concepts presented in this story.

While the material subjects in Permutation City are firmly planted in sci-fi, it also puts concepts such as what it means to "be" human both objectively and subjectively at the forefront.

Whether you are an ardent fan of computer science, biology, physics, or even philosophy, this book will elicit some kind of respect from you for its depth in those regards.

This book does lean heavily into both hard science and fiction, but quite honestly it takes the concepts so far that that distinctions between the two are trivial.

What this book ISN'T is a flashy science fiction romp with action and adrenaline for just for the sake of excitement. What we DO have is a deeply thought provoking series of events and perspectives that challenge how evolving technology can redefine or completely do away with our current concepts of humanity.

My only real cons are that Greg goes to such lengths to explain and take you to each of his thought points and conclusions, that the actual "story" is relatively light.

Now, if you enjoy staying in those thoughts and sort of letting them gestate, this won't be much of a problem. If however, these thoughts don't resonate with you, you might find yourself waiting for the next "thing" to happen.

Sort of on the other end of that, I felt that the conclusion of the book was a bit hasty. When considering the effort that went into making sure that the reader has bought and understood the rules of the world, the end felt a tad rushed and unearned.

It's not to say that it's bad by any means, it just felt as if SOMETHING that fit a more typical sci fi ending had to happen just for the sake of it, rather than the story logically leading there.

The fact that this book was written in blew my mind, as many of the technologies mentioned seem like logical progressions of things that have only become common in the past 10 or so years, so the foresight alone is incredible.

All in all this book is a must read for any hard science fiction fan. While not perfect, enough love and attention clearly went into it to add it to your collection.

Greg Egan is an important writer in the tradition of Azimov, Verne and Wells. Like them, he explores the feasable technologigies of his era and expands their scope and implications for individuals and civilization.

Permutation City addresses immortatality, cloning and the utility of life in unique ways and in depth.

Simly using the terms science fiction, ethical exploration or fantasy-allegory to catagorize this book and his output in general is both difficult and misleading.

Try this novel or sone of his short stories and decide: You may become addicted to him. This book and this author are one of my most frequent recommendations to my friends, especially millenial I am a geezer.

But not to all: Enjoying technologyand both knowing and enjoying learning about scientific concepts is critical. High school physics or computer science and reading about current events in the science pages of, say, The New York Times is enough.

So too, if you enjoyed reading Carl Sagan's or Stephen Hawking's popular books then you are in the potential audience.

Kindle Edition Verified Purchase. I wanted to like this book. I gave it a chance. The concepts are interesting, and the setup was fine in the first half, then it fell flat.

It's very rare for me to not finish a book, so this was a rare dud from a decent author. I don't feel like writing a long review, but all of Greg Egan's works will make you think.

Some people find Egan's books to be hard reads, and indeed the author has even suggested that people take notes when reading some of his works.

This is probably the best book he's written IMHO. The premise of this is mind-blowing, and without offering spoilers, this is an entirely new twist on first-contact with a sentient species, among many other concepts and Egan writes so well about virtual reality, you end up hoping that if we ever achieve this level of VR, that his works will be used as a guidebook to implementation.

It's also an exploration of what consciousness may mean. Some say Egan doesn't develop his characters very well.

And I somewhat agree. But he uses his characters more to help illustrate the ideas in his books than to be the primary focus. It helps to have a technical background and basic understanding of computer science IMHO to fully appreciate this book.

You also probably won't get a full appreciation for all of the ideas without rereading it a couple of times.

Other reviewers are pinning this as "very hard" sci-fi, but it feels a lot more like an exploration of philosophy of mind. The book is well written, with a pretty straightforward style.

The explanations of hardware real or simulated are a little hand-wavey, However, this doesn't detract from the book because the real story is the "software": The author uses the experiences of these characters to explore and share ideas about being a mind.

Does it matter how or where the pattern that is "you" is computed? What are you if you can change your emotions, memories and capabilities at will?

How do beings with these capabilities relate and interact with each other? If having a set of fairly interesting characters explore these questions is remotely interesting to you, then pick up this book.
