Cryonics and Personal Survival
Identity, reconstruction, and evidence-conditioned revival
If a future technology reconstructs a person, has that person survived? Technical restoration, consciousness, identity, and meaningful psychological continuation require separate answers.
The argument
The paper compares original-brain repair, reconstruction anchored in surviving information, and digital uploading across competing metaphysical views. It treats preservation and eventual revival as distinct decisions and examines the importance of future custody and consent.
How to read this assessment
Its numerical comparisons concern assumed successful future constructions. They are not forecasts of a present patient’s chance of successful preservation and revival, or a recommendation to enroll in cryonics.
A question worth pursuing
What must be preserved for restoration to count as survival rather than replacement?
