Questions: Bodily Continuity Theory of Personal Identity

Question 1

According to animalism, what happens to 'you' if your entire brain is gradually replaced by silicon chips that preserve all your memories, personality, and psychological states perfectly?

• A. You persist, because psychological continuity is preserved throughout the gradual process
• B. You cease to exist at some point, because you are a biological organism and the animal does not persist through radical replacement of biological tissue with non-biological material
• C. You persist, because gradual replacement is less disruptive than sudden replacement
• D. The question is unanswerable because animalism only applies to actual biological cases

Answer: (B)

Animalism holds that you are a biological organism and persist just as long as the organism persists. Replacing biological tissue with non-biological material — even with perfect psychological preservation — would constitute the organism ceasing to exist as an organism. Psychological continuity (option A) is precisely what animalism rejects as the criterion for personal identity. Gradualness (option C) does not change the metaphysical fact for the animalist. This case highlights the sharpest divergence between animalism and psychological continuity theories.

Question 2

A person enters a persistent vegetative state (PVS) with no conscious experience, no memories, and no psychological continuity with their earlier life. What does animalism say about whether this individual is the same person who lived before the injury?

• A. The individual is no longer the same person, because personal identity requires psychological continuity
• B. The individual is the same person if and only if they retain some latent capacity for consciousness
• C. The individual is the same organism as before — biological life continues, so identity continues — regardless of the loss of psychological states
• D. The individual exists in a legal but not a metaphysical sense

Answer: (C)

Animalism tracks biological continuity, not psychological continuity. As long as the organism remains biologically alive — which a PVS patient does — the animalist says it is the same individual. This is one of animalism's most striking and controversial implications: even total loss of psychological function does not end identity, because identity is grounded in the animal's biological persistence, not its mental life. Option A describes the psychological continuity view that animalism directly opposes.

Question 3

Animalism implies that psychological changes — including radical personality shifts, total amnesia, or loss of consciousness — can end personal identity.

• T. True
• F. False

Answer: False

This is the opposite of animalism's position. Animalism grounds personal identity in biological continuity, not psychological continuity. Psychological changes, however dramatic, do not end identity on animalist grounds — what matters is whether the organism continues to live. This is precisely what distinguishes animalism from psychological continuity theories: the animalist says a person with total amnesia is still the same individual, while the psychological theorist may deny this.

Question 4

The thinking animal problem is a challenge directed at animalism, not at psychological continuity theories.

• T. True
• F. False

Answer: True

The thinking animal problem targets animalism specifically. The argument: right now, a human animal is sitting in your seat thinking your thoughts. Animalism says you are that animal. But persons and animals seem to be distinct (they can come apart in various cases). If both the person and the animal are thinking the same thoughts in the same place, there appear to be two thinkers where we expect one. This is a problem for animalism because it either forces the conclusion that persons and animals are strictly identical (with troubling implications) or that there are too many thinkers. Psychological continuity theories do not face this challenge in the same form.

Question 5

What does animalism mean by saying you are a human animal rather than a person who inhabits or has a body? Why does this distinction matter for cases like persistent vegetative state?

Model answer: Animalism says your fundamental nature is biological: you are the organism itself, not a mind or person that exists separately from and within a body. The organism is the primary subject of experience and identity. This means personal identity tracks whatever tracks the organism — biological life, not psychological life. In PVS, the organism remains alive even though all psychological states are gone. For the animalist, the same individual persists; for a psychological continuity theorist, there may be no person remaining. The distinction matters because it determines whether biological persistence without psychological continuity is sufficient for identity.

The contrast with psychological continuity theories is crucial: those theories say the organism is at most a vehicle for the person, and what matters is the continuity of mental states. Animalism inverts this: the person just IS the animal, and psychological states are properties of the animal, not the grounds of its identity. This has implications for PVS, fetal personhood, brain transplants, and the ethics of death — wherever biological and psychological facts about a human being come apart.
