Philosophical zombies are defined as beings that behave exactly like conscious persons but lack consciousness, inner experience, or qualia [1][2], directly engaging the hard problem of why physical processes give rise to consciousness rather than zombie-like behavior [3]. This thought experiment highlights limitations in functionalism and argues for the logical possibility of zombies, implying consciousness is not reducible to physical facts [4][5].

referenceDavid Chalmers uses two-dimensional semantics to argue that: (1) a philosophical zombie would only be able to understand secondary intentions; (2) there are logically possible scenarios where two non-zombies have the same primary intentions (such as the phenomenological realisation of red) that correspond to different secondary intentions (such as different wavelengths of light); (3) in such scenarios, the zombies' communication would face challenges not faced by the two non-zombies; (4) even if consciousness lacks causal influence, it still inserts itself into phenomenal judgements; (5) an adequate theory of consciousness must be able to reconcile this fact.
