# Greg Egan **Domain:** Science Fiction / Computational Personhood **Greg Egan** is a science-fiction writer whose work repeatedly examines computational minds, copied persons, virtual worlds, post-biological civilization and the physical conditions under which identity can persist. His fiction is especially useful to this corpus because it treats metaphysical questions as systems problems with explicit substrates, constraints and consequences. Egan belongs in the intellectual lineage of [[wiki/Pantheon|Pantheon]] without being reduced to a prediction claim. Both bodies of work ask what happens after minds become executable: how copies diverge, how virtual habitats acquire politics, how embodiment becomes optional but material dependence remains, and how cosmology changes when cognition can migrate. The relevant route is through [[wiki/Post-Biological Personhood|Post-Biological Personhood]], [[wiki/Substrate-Relative Habitability|Substrate-Relative Habitability]], [[wiki/Continuity Evidence vs Continuity|Continuity Evidence vs Continuity]] and [[wiki/Simulation Welfare|Simulation Welfare]].
