- The philosophical zombie (p-zombie) argument is criticized as an unfalsifiable and incoherent thought experiment that has dominated philosophy of mind for 28 years.
- David Chalmers popularized but did not originate the p-zombie idea; it traces back to Keith Campbell and Robert Kirk as a dualist argument.
- The argument relies on modal logic to present p-zombies as conceivable, but this conceivability is based on a stipulation rather than evidence, essentially assuming what it tries to prove.
- Chalmers' appeal to epistemic possibility (ignorance-based) is weak because it reflects gaps in understanding, not metaphysical reality, similar to outdated concepts like vitalism.
- The analogy of identical laptops—one functional and one blank—highlights the incoherence: identical physical systems producing different outcomes without reason is implausible.
- Chalmers invents 'psychophysical laws' to sustain the p-zombie argument, but these are ad hoc and lack empirical support, unlike scientific laws like Maxwell's electromagnetism.
- The p-zombie scenario contradicts evolutionary biology, as it posits identical brains evolving without consciousness, ignoring the functional costs and adaptations of real brains.
- The argument is structured with layers of 'plot armor' (e.g., modal logic, psychophysical laws) to protect its core intuition: that consciousness cannot be physical, making it unfalsifiable.
- Despite criticisms, proponents of the zombie argument remain unmoved, showcasing its resilience as a philosophical construct rather than a sound empirical claim.
- The essay concludes that p-zombies, like fictional zombies, cannot be 'killed' because they were never truly alive—they are a product of philosophical imagination, not reality.
