What you'll learn

• The key differences between immortality of the soul, rebirth, reincarnation, replica theory and resurrection.
• How different religious traditions explain what, if anything, continues after death.

• How to use J. Hick’s replica theory in evaluation, not just as description.

The big question: what continues after death?

This topic is not just asking, “Do people live after death?” It is asking a sharper question: what exactly survives, continues, is reborn, is recreated, or is restored?

One helpful way to revise the topic is to map each view according to three questions: Is there a permanent soul? What happens to the body? What makes the future person the same person?

Personal identity: why it matters

Before comparing traditions, you need the philosophical background.

If someone says, “I will survive death,” you can ask: in what sense will it still be you? There are several possible answers:

• Bodily continuity: the same body, or a restored body, continues.
• Psychological continuity: memory, character and consciousness continue.
• Soul continuity: the same immaterial soul continues.
• Causal or moral continuity: one life leads to another through karma, even without a permanent soul.

Immortality of the soul

Immortality of the soul is the belief that the soul is non-physical, spiritual, and continues to exist after the death of the body.

This is often linked with dualism, the view that human beings are made of two different kinds of reality: body and soul. In Plato’s philosophy, especially in the Phaedo, the soul is superior to the body and naturally belongs to a non-material reality. The body dies, but the soul can continue.

In some religious traditions, soul-language is also used to describe an intermediate state after death. For example, many Christians speak of the soul being with God, although classical Christianity also teaches resurrection of the body. This distinction matters: immortality of the soul is not exactly the same as resurrection.

Strengths and weaknesses

The strength of this view is that it gives a simple answer to personal identity: the same soul continues. It also fits religious beliefs that humans are more than physical organisms.

However, it faces major challenges. If the soul is non-physical, how does it interact with the body? Also, thinkers influenced by materialism — the view that reality is ultimately physical — argue that personality and memory depend on the brain. Aristotle is also a useful contrast with Plato: for Aristotle, the soul is the “form” of the body, not obviously a separable ghost-like substance.

Rebirth: no unchanging soul

Rebirth is especially associated with Buddhism. It is the belief that life continues in a new form, but without an unchanging soul passing from one body to another.

A key Buddhist teaching is anatta, meaning “no permanent self” or “no unchanging soul”. The person is made up of changing physical and mental processes. When one life ends, karma conditions a new life, rather like one flame lighting another flame: there is continuity, but not a single fixed substance travelling across.

Karma is crucial here. It is not usually understood as punishment from God. Instead, it is a moral and causal law: actions motivated by greed, hatred and ignorance produce suffering, while wisdom and compassion help move towards liberation.

Evaluation

Rebirth avoids the problem of explaining a detachable soul. It also fits the Buddhist view that clinging to a permanent self is part of the problem.

The difficulty is moral responsibility. If there is no unchanging self, in what sense is the later life responsible for the earlier life’s karma? A Buddhist response is that responsibility depends on causal continuity, not on a permanent soul.

Reincarnation: transmigration of souls

Reincarnation is the belief that a soul or self is reborn in another body. The technical term transmigration means the movement of the soul from one body to another.

This is strongly associated with Hindu traditions. Many Hindu thinkers distinguish between the temporary body and the atman, the true self or soul. The atman passes through many lives within samsara, the cycle of birth, death and rebirth. Karma shapes the circumstances of future lives. The ultimate goal is moksha, liberation from samsara.

Sikh traditions also include belief in rebirth and liberation, often expressed as mukti, although Sikh teaching places strong emphasis on God’s grace and living in harmony with divine reality.

J. Hick’s replica theory

Replica theory is J. Hick’s attempt to show that life after death, especially resurrection, is logically possible. Hick argues that a person could die in one body and continue in another body if God recreated that person as an exact psycho-physical replica. Psycho-physical means involving both mental and bodily features.

Hick was not simply defending a ghostly soul. He treated persons as embodied beings. His theory tries to make sense of resurrection without needing the original atoms of the body to be reassembled.

Hick develops the idea through thought experiments. Imagine someone disappears in London and an exact replica appears in New York with the same memories, character and bodily features. Hick then extends this idea to death: if God creates the replica after bodily death, perhaps the person has survived.

This connects with Hick’s idea of eschatological verification: a belief about life after death could be verified after death if true, even though it cannot be verified by the dead person if false.

Evaluation of Hick

Hick’s theory is useful because it supports resurrection while avoiding crude physicalism. It also respects the idea that persons are embodied, not just souls trapped in bodies.

But there is a serious problem: is a replica really the same person, or only a copy? If two replicas were created, both could not be numerically identical with the original person. So psychological similarity alone may not be enough.

Resurrection: bodily restoration by God

Resurrection is the belief that God will restore the dead in bodily form to eternal life. This is central in Christianity and Islam, and also appears in important strands of Jewish belief.

In Christianity, Jesus’ resurrection is the model and guarantee of future resurrection. Paul describes resurrection life as a transformed “spiritual body” in 1 Corinthians 15, meaning not a ghost, but a body transformed by God. In Islam, belief in the Day of Judgement includes bodily resurrection, accountability, paradise and hell. In Judaism, beliefs vary, but many forms of rabbinic Judaism include hope in resurrection and the world to come.

Resurrection differs from immortality of the soul because it values the body. The final hope is not simply escape from physical existence, but restored embodied life with God.

Evaluation

Resurrection has strong religious power because it connects life after death with divine justice: evil is judged, suffering can be redeemed, and embodied human life is affirmed.

The challenge is coherence. If bodies decay, what body is raised? Hick’s replica theory helps here: God does not need to gather the same particles, but can recreate the person. However, critics may still ask whether this is genuine survival or divine copying.

Comparing the five views

Building an evaluative judgement

For Edexcel essays, avoid listing views as if they are all the same. A strong answer compares them around a central issue, such as personal identity, justice, or coherence.

A balanced judgement might be:

• Rebirth is internally coherent within Buddhism because it does not require a permanent soul.
• Reincarnation gives a clear moral structure through karma, but may struggle to explain why most people do not remember past lives.
• Immortality of the soul gives a simple continuity claim, but depends on a controversial dualism.
• Resurrection, especially with Hick’s replica theory, may be philosophically defensible if God exists, but is less persuasive to a materialist or atheist.
