Justin Younger reviewed Permutation City by Greg Egan
Review of 'Permutation City (Subjective Cosmology #2)' on 'Goodreads'
3 étoiles
Tough read but very prescient.
Permutation City is a 1994 science-fiction novel by Greg Egan that explores many concepts, including quantum ontology, through various philosophical aspects of artificial life and simulated reality. Sections of the story were adapted from Egan's 1992 short story "Dust", which dealt with many of the same philosophical themes. Permutation City won the John W. Campbell Award for the best science-fiction novel of the year in 1995 and was nominated for the Philip K. Dick Award the same year. The novel was also cited in a 2003 Scientific American article on multiverses by Max Tegmark.
Tough read but very prescient.
Speaking my language at 14 or 40, hard implications for immortality and self-redefinition in computationally simulated brain scans and artificially evolved life.
Interesting as a series of thought experiments in the philosophy of transhumanism
It's hard sci-fi, with the basic conceit that fundamentally, physics literally is math, that everything mathematical literally exists. But what's most gripping is the description of consciousness and simulated or repeated consciousness, and slicing it, and duplicating it, and messing with it. Made me feel weird while reading it, and still does, and informs the way I think about the mind.
