5.0 out of 5 stars Shockingly Good May 7 2002
By Justin
Format:Mass Market Paperback
This is perhaps the finest work of Computer Science based Science Fiction ever written. The most stunning thing here is that Greg Egan actually knows what he's talking about, and isn't afraid to stick to it, in exactly the way that so many "cyber" writers... don't. He actually understands recursion and virtualization, not just throwing words out to sound cool. He doesn't retreat into literary silliness or ridiculous anthropomorphic characterization in a feeble attempt to be some sort of artsy novelist. He keeps it believable, and extremely good.
This is the book I would have written, if I had time (and ability!) to write a novel about recursion and artificial life.

5.0 out of 5 stars Mind Boggling Jan. 25 2002
Format:Mass Market Paperback
I'd have to rate this book as one of my all-time favorite SF books. I still freak out a bit if I think too hard about his dust hypothesis.
The best thing about this book is that I read it soon after I had read "The Minds I", a collection of essays about AI and human consciousnes. I suspect that Egan has read the same book, since many of the concepts of Permutation City are based on the thought experiements in The Minds I. This is not to say that Egan's book is not original, as the title suggests, the book is a riff or fugue on a number of concepts related to identity and consciousness.
Most of his wild extrapolations follow perfect logic if you accept the basic premise that a conscious software entity can be created. The idea that, if such an entity exists, maintaining the software state while shutting down the program, then restarting it later from the same state would be experienced by the entity as instantaneous, then following that a succession of these saved states in any chronological order should be perceived as the same experience is mind bending.
Amazon should bundle Permutation City and The Mind's I (and maybe Goedel, Escher, Bach) -- they make a great matched set.

5.0 out of 5 stars Egan's cusp book Jan. 4 2002
Format:Mass Market Paperback
One of his last books that maintains some accessibility and entertainment value to balance off his increasingly abstract theses. After this, his books are quite difficult but this one is a lot of fun -- especially for CS people. Be warned however that it's definitely *hard* sf....

4.0 out of 5 stars Are you sure this is reality? Jan. 4 2002
Format:Mass Market Paperback
An excelent book. What would happen if you could be downloaded to a mainframe? And if your virtual self creates a virtual world that in time creates self consciounness?. It could explore a little more the relation between the autoverse (a creation within the creation) and the creators, but still Hard Sci Fi at its best

Format:Mass Market Paperback
The concept of mind uploading has been a common theme in fiction and science fiction for years. The concept of personality transferal and immortality has captivated mankind for centuries.
Egan takes these themes and combines them artifical reality.
A play on Descartian themes and the question of "what really is reality?"
The end result of Permutation City is a internal world outside of our reality. A world that exists purely in digital form. How does this world exist in regard to ours? Can a world like that have another world inside it? Without its own concept of "our" reality, could it therefore understand/ comprehend our reality? Can we in the same vein comprehend another reality outside our own?
It raises further questions on the nature of artifical electronic intelligence- Whilst people may exist in this electronic form, would shutting down their world be murder? Do they really exist? Do they really have free will? Is their future predetermined?
At points this novel has a little to much detail, however it is an excellant story.
A book that, if read deeply, has a surprising trail of deep dualistic and philosophical issues and questions.

5.0 out of 5 stars Upload your Mind! Dec 23 2000
Format:Mass Market Paperback
Mobius Dick writes songs about mind uploading, but not many people have successfully written books about it. Egan has, and this one is excellent. The opening paragraph is one of the best-written opening paragraphs in science fiction, and the book continues in that vein. It's just damned good.

4.0 out of 5 stars Seemingly endless details, but still good... Dec 4 2000
Format:Mass Market Paperback
Permutation City is a notable cyberpunk novel by Greg Egan, which is worth giving a try if you fancy this genre of literature. Here we have a story about a young man, Paul Durham, who uploads the contents of his brain to a computer. In doing so, he seemingly acquires the gift of immortality, which is granted so long as he carries on the rest of his life in this virtual world created for him. That's not such a bad deal to begin with, but it doesn't take long for him to experience the tremendous sense of isolation and uselessness. In the VR, Paul is simply a spectator of the world around him and every glitch in the construct serves as a violent reminder that he is no longer flesh and blood.
I must warn you that Egan goes to great extent to provide the reader with plenty of meticulous details that add to the realism and plausibility of the storyline. Early in the story, I think it's fantastic because it does so much to paint a vivid picture for the reader. However, there are plenty of times when it does weigh down the story. For example, Egan beat Maria's experiment with mutose to death by explaining the actual chemistry involved, which I found unnecessary. It seemed to me like Egan was more or less showing off how learned he is in different subjects. This is definitely a novel you must read slowly if you plan on getting the most from it. Yet, I still found myself tempted to put it down at times because I was overwhelmed with too much detail.
On the other hand, I did love the underlying human issues presented in the story. The entire plot toys with the philosophical quandary of personal identity. If everything in the VR is not truly real, then can the copy of Paul be considered human? Or is he just another jumble of computer code simulating a human?

1.0 out of 5 stars fascinating subject matter in a boring book.
The author has managed to make a fascinating subject somehow seem boring and predictable. At least that is what I thought of the characters and plot of this book. Read more
