Axiomatic (story collection)
Axiomatic (ISBN 0-7528-1650-0) is a 1995 collection of short science fiction stories by Greg Egan. The stories all delve into different aspects of self and identity.
The Guardian describes it as "[w]onderful mind-expanding stuff, and well-written too."
Neural Mods
Several Axiomatic stories involve "neural mods", usually presented as small tubes containing powder inhaled through the nose, which alter the brains of their users in highly specific ways with advanced nanotechnology.
In the collection's eponymous story "Axiomatic", the protagonist enters a store selling mods not only for every variety of psychedelic experiences, but for altering one's personality traits, sexual orientation, and even religion. The protagonist seeks a custom-made mod that will suspend his moral convictions long enough for him to murder his wife's killer. In "The Walk", an executioner offers his victim a mod that will cause him to accept the killer's personal philosophy, and thus help him cope with his death.
Neural mods feature prominently in Greg Egan's first science fiction novel, Quarantine.
The Jewel
Two stories, "Learning to Be Me" and "Closer", involve a different kind of neural implant called a "jewel"—a small computer inserted into the brain at birth that monitors its activity in order to learn how to mimic its behavior. By the time one reaches adulthood, the jewel's simulation is a near-perfect predictor of the brain's activity, and the jewel is given control of the person's body while the redundant brain is discarded. In this way, people with the jewel can eliminate the cognitive decline associated with aging by implementing their minds on a machine. Also, by transplanting the jewels into cloned bodies genetically altered to develop without brains, they can live youthfully forever.
"Learning to Be Me" explores the consequences of a man's jewel failing to synchronize with his brain, while in "Closer" a couple arranges to have the internal states of their jewels gradually made more similar so they can temporarily become a single person.
Minds uploaded to computers
Minds are transferred to computers in a different style in "A Kidnapping". People wishing to upload themselves into computer simulations to avoid death are periodically scanned so that a recent copy of the individual can be simulated in the event of death. Due to limited computing resources, however, uploaded people are simulated slower than their physical counterparts, making communication between them difficult.
This system of uploading minds features prominently in Greg Egan's novel Permutation City.

Reviews of Axiomatic
- Danny Yee, 1995: "There are more original ideas in Axiomatic than I've seen in a science fiction collection for ages, and anyone who likes hard science fiction will revel in them." [1]
- Christina Schulman, 1998: "Egan's ideas stretch your head the way the better cyberpunk does, without cyberpunk's self-indulgent grime and alienation." [2]
