Dilemma

If a teleporter copied and destroyed you, would you have survived?

The Star Trek transporter problem: a machine scans your body atom by atom, transmits the pattern, builds an exact duplicate at the destination, and dismantles the original. Whether you arrive at the destination or die in the scanner is the question; the answer depends on what you are.

Context

Derek Parfit made the teleporter the canonical thought experiment in personal identity. The case is no longer pure philosophy: mind-upload speculation, whole-brain emulation research, the prospect of digital backups of biological minds, and even less exotic cases (general anesthesia, deep sleep, hibernation) raise versions of the same question. What we say about the teleporter forecasts what we will say about the technologies actually being built.

Why it matters

If teleportation preserves the person, mind-upload is survival; if it does not, mind-upload is a particularly elaborate kind of suicide that produces an heir. The ethical and practical stakes (would you step into the scanner? would you let your child?) depend entirely on which is true, and the answer depends on what you take the self to be.

The stances

Different body, different person — you died in the scanner.

74 schools

On this view, the body is the locus of identity, and the body that walks out at the destination is a new body — not yours. The person on the receiving end has all your memories and thinks they survived, but you didn't. The scanner is a death machine that produces a copy.

Why these schools land hereThe body-bound cluster reads personal identity as bodily continuity. Naturalism, Determinism, Pragmatism, Phenomenology, Reformed Christianity, Catholic Thomism, LDS, Hylomorphism, and the rest of the cluster mostly agree that teleportation in the destructive-copy sense is not survival, even if the resulting person is qualitatively identical. (Reformed Christianity adds that resurrection is different: God's reassembly of one's specific body into eternal life is bodily continuity guaranteed by divine action, in a way the engineering case isn't.)

Where this stance leads ⓘ

The soul accompanies the person; engineering can't transfer it.

63 schools

On this view, the person includes a non-physical aspect that the teleporter cannot scan, transmit, or reconstruct. The copy at the destination has your body and memories but is, in the relevant sense, soulless — or has a different soul, perhaps newly created. You did not survive; something else, structurally similar, came into being.

Why these schools land hereSoul-substance schools — EO, Lutheran, Islamic, Jewish, Zoroastrian, Bahá'í, Cartesian Dualism, Jainism, Kabbalah, Neutral Monism, Platonism, Hermeticism, Dvaita, Sāṃkhya — read the person as essentially including a non-bodily aspect. The teleporter case is, on this signature, a clear failure: the engineering acts on the body, but the soul is not the kind of thing the engineering addresses.

Where this stance leads ⓘ

You are the pattern; the pattern survives the substrate change. You arrive.

18 schools

On this view, you are the trans-temporal pattern that has shown up in this body up to now. The teleporter preserves the pattern — destroys one instance, builds another — and the pattern is what matters. You step in and you step out. The fact that the substrate changed is incidental.

Why these schools land hereThe trans-temporal-pattern cluster — Eternalism, Multiverse, Quantum Realism, Panpsychism, Transhumanism, Dataism, ancestral-temporal indigenous schools — reads identity as a pattern not bound to a particular substrate-instance. Transhumanism in particular endorses the teleporter case explicitly: this is exactly what mind-upload is, and on the pattern-theoretic view, it is straightforwardly survival.

Where this stance leads ⓘ

There was no fixed you to either survive or fail to; the question is malformed.

29 schools

On these views, the question presupposes a fixed self whose continuity is the issue. There isn't one. The teleporter case feels more troubling than ordinary sleep, dementia, or growth, but the framework is the same: a stream of experience stops at the scanner, a new one starts at the destination, and the question of whether they are 'really the same' is the question of which vocabulary you find most useful.

Why these schools land hereNo-fixed-self schools — Buddhism (especially anatta), Existentialism, Postmodernism, Process Philosophy, Phenomenalism, Constructivism, Yogācāra, Taoism, Sikhism, the relational skeptics — treat the cross-time identity question as a request for an answer the question's framing won't support. Practically, this cluster is most comfortable about teleportation in the sense that they're equally relaxed about the more ordinary cases the teleporter resembles.

Where this stance leads ⓘ

The distinction between scanner-you and destination-you is conventional all the way down.

17 schools

On non-dual views, the difference between you-now and you-tomorrow is already conventional; the additional difference between you-here and you-at-the-destination is conventional in the same way. The case is illuminating about how everyday identity already works rather than uniquely puzzling.

Why these schools land hereThe Singular cluster — Advaita Vedānta, Sufism, Idealism, Solipsism, Neo-Platonism, Rationalism, Transcendentalism — reads all apparent selves as perspectival distinctions within a single underlying reality. The teleporter case adds nothing the everyday already implies. Practical advice (would you step in?) is at the conventional level, where ordinary care for the apparent self applies.

Schools the coordinates don't place

These schools don't satisfy any stance's coordinate pattern strongly enough to be assigned — either because they decline to commit on the question (Confucianism is famously silent on what comes after; Pyrrhonian and pragmatist traditions suspend judgment), or because their attribute signature crosses categories in a way the five buckets don't capture.
