Dilemma

Could the dead, in principle, be brought back?

If we had perfect information about who someone was — their connectome, their behavioral patterns, their history — could we, in principle, restore them? The question is partly engineering, but the ceiling on the engineering is metaphysical.

Context

Cryonics, whole-brain emulation research, the prospect of digital backups of biological minds, and various religious doctrines of resurrection all share an underlying question: is the information that constitutes a person the kind of thing that, in principle, could be restored after biological death? The empirical question is one matter; the philosophical question is whether the answer is determined entirely by the information's conservation status — and that depends on what kind of conservation laws the cosmos has.

Why it matters

The framing bears on the moral standing of cryonics, on the philosophical seriousness of mind-upload, on religious doctrines of resurrection, and on how to read death itself — as the destruction of something or as the change-of-state of something that, in principle, remains addressable.

The stances

The information that constitutes a person is conserved; restoration is in principle possible.

82 schools

On this view, the information that made the person is preserved by the structure of the cosmos — physical, divine, or both. Restoration is an engineering or theological question, not a metaphysical impossibility. The Christian, Islamic, and Jewish doctrines of bodily resurrection share the formal commitment with secular pattern-realist longtermism: the information persists; the question is what agency can act on it.

Why these schools land hereSchools with info_personal_conservation=Conserved — the religious resurrection traditions (Catholic, Reformed, Lutheran, LDS, Islamic, Jewish, Bahá'í, Dvaita, Manichaeism, Zoroastrianism), pattern-survival naturalists (Eternalism, Multiverse, Quantum Realism, Dataism, Transhumanism, Gamer), Cosmic-ordering soul-affirming schools (Jainism, Sāṃkhya, Platonism, Hylomorphism, Panpsychism, Process, Rationalism), Spirit-relational schools with ancestral persistence, and non-dual schools (Advaita, Sufism, Transcendentalism). They differ enormously on who or what could in principle do the restoring — God for the religious schools, sufficient technology for the secular ones, the One for the non-dual schools — but share the underlying personal-pattern-conservation commitment that makes the question meaningful.

Where this stance leads ⓘ

The information dissipates with the substrate; restoration is in principle impossible.

105 schools

On this view, the information that made the person is not preserved past the substrate's dissolution. No sufficient technology and no divine agency can restore what didn't persist. A 'restored' person would be a new person with the same name, not the original.

Why these schools land hereSchools with info_personal_conservation=Non-conserved + matter_conservation=Conserved — Buddhism (especially anatta), Existentialism, Postmodernism, Constructivism, naturalist materialists (Realism, Determinism, Naturalism, Empiricism, OOO, etc.), and Cosmic-ordering schools without personal-soul doctrine (Confucianism, Stoicism, Taoism, Deism) — read the personal pattern as substrate-dependent. The cluster's typical position on cryonics and mind-upload is principled skepticism: the work doesn't restore; it constructs.

Where this stance leads ⓘ

What is held by God or sustaining practice can be restored; what isn't can't.

18 schools

On these views, the conservation of personal information depends on what is sustaining it. The Eastern Orthodox doctrine of resurrection holds that the person is preserved in God's memory and restored in the resurrection by divine action operating on what God has held. What is preserved only on the dissolving body or in fading human memory is, on this view, genuinely released.

Why these schools land hereSchools with energy_conservation=Variable — Eastern Orthodox Christianity, Kabbalah, Hermeticism, Neo-Platonism, Sikhism, Afrofuturism, Dualism, Idealism, Solipsism, Psychedelic / Entheogenic — share the read of conservation as conditional on sustaining presence. The cluster's doctrines of restoration typically locate the preservation in something sustaining (divine memory, cosmic record, ritual continuity, the One's self-disclosure) rather than in either pure information realism or pure substrate-dependence.

Where this stance leads ⓘ

Nothing of what was can be restored; restoration is wishful framing.

3 schools

On this view, neither the information nor the conditions that hosted it persist past the dissolution. Talk of restoration mistakes the continuity of names or roles for the continuity of the underlying being. The person is gone; any 'restoration' is a separate being whose relationship to the original is conventional.

Why these schools land hereThe nothing-conserved cluster — Nihilism, Psychedelic, Wellness in some readings — denies the conservation that would make restoration meaningful. The position is unsentimental about death and uninterested in the various restoration projects that depend on the conservation framing.
