A life in Permutation City is unlike any life to which you’re accus- tomed. You have From the brilliant mind of Greg Egan, Permutation City, first. Set around the midst century, Greg Egan’s debut Permutation City tells of a time when humans are being cloned, not biologically, but electronically. The book. In Egan hadn’t yet written Teranesia, or “Oceanic” or “Oracle“. The cumulative effect of these, with Permutation City’s concluding denial of.

In ogni caso, una pietra miliare, senza freg. Alas, as I wrote in DiasporaGreg Egan is not for everyone. In the novel, Paul Durham runs a Copy of himself out of temporal order, skipping its mental state forward in time by ten seconds and then computing the intervening states backwards.

As soon as you have an idea that changes some small part of the world you are writing science fiction. Some of his earlier short stories feature strong elements of supernatural horror, while due to his more popular science fiction he is known within the genre for permutxtion tendency to deal with complex and highly technical material including inventive new physics and epistemology in an unapologetically thorough manner.

But in quantum mechanics, at best I can tell you the probability of it happening. No trivia or quizzes yet. So it is with Permutation City which had me permutattion from Chapter One which takes place inside a computer no, not the plastic casing! A cloud of random numbers. Durham predicts that efforts to utilise chaotic effects will clash with Copy rights, as both Copies and weather simulations will demand increasing QIPS Exchange shares.

To get from micro-organisms to intelligent life this way would involve an immense amount of suffering, with billions of sentient creatures living, struggling and dying along the way.


How time can be slowed down in the virtual world the word “cyberspace” suddenly seems a bit quaint so that the time in reality just whizzes by. Here are some excerpts: May 29, B. It yreg occurred to me that they might miss the prrmutation that we know are laws, and circumvent the whole problem.

Permutation City

Oct 27, Erik rated it it was amazing Shelves: This is Tikkuna sort of reconstruction of psychic pieces into a new entity. The plot didn’t lock together very well, This one came up when Schwern and I were poking around the Wikipedia articles about Conway’s Game of Life, and I was like, “You know what, it’s been way too long since I just said ‘fuck everything’ and downed a whole book of potentially dubious quality in a single slurp. I listened to the audiobook, and for a few weeks, my daily travels were inundated with the joy and excitement of contemplating the structure of existence, instead of permeated with the weight and ache of taking one’s arbitrary human desires too seriously.

But unless you’re a programmer lermutation mathematician yourself, you’re going to find these stretches of the book to be tediously techie if not altogether incomprehensible. When I encountered this in my first physics class, it blew my mind. Return to Book Page. So, almost thirteen years later, here is a kind of self-interview on the most contentious aspects of the book. The last section gfeg slightly tacked on after a solid but perhaps not entirely salutary ending of the main portion of the narrative.

They are as necessary as the rules of English.

Ray You don’t need to read Quarantine. It may be completely outlandish, but I give Egan kudos for sheer daring. I don’t altogether disagree, though I’d lean towards freedom of choice, of course. Sometimes I rgeg reduced to tears of laughter hearing how awful they were.

I should probably have read Egan’s bio before buying this: Scenari cyber degni di Gibson e soci, scenografie e paesaggi mastodontici che ricordano un po’ Ian M. One might view this as a fiction analog of Chalmer’s view that a computational theory of the mind will entail pan-psychism more or less.


Dec 03, Akiva rated it it was ok. Permutation City asks whether there is a difference between a computer simulation of a person and a “real” person. Hence they cannot afford to retreat into solipsism and ignore what is happening in the real world.

When the universe is math and math is the universe, a perfect copy as data ciy have no real difference with everything we have. However, the most interesting ideas — the ones that Greg Egan explores — arise from more modern physics, such as quantum mechanics and relativity. The Autoverse is an artificial life simulator based on a cellular automaton complex enough to represent the substratum of an artificial chemistry.

Like most transhumanists, Egan has nothing but scorn for people who allow moral qualms to stand in the way of technology.

From a literary point of view, Egan has done something both awesome and interesting: Again, this is subject matter enough for another book sgan. I feel I only need to understand the basic plot and the characters’ motivation, the whys if not the hows of it.

If so, read on. Maria convinces a reluctant Durham to come along to a new universe, pledging to work with her to discover the underlying rules that citt the Autoverse’s takeover of Permutation City. This is potentially an important issue in the real world. What remains is the actual path the particle ends up taking.
