David Chalmers is directly linked to philosophical zombies as he popularized the thought experiment [1], defines them as beings behaviorally identical to humans but lacking conscious experience {fact:5,8}, and argues their conceivability proves consciousness is irreducible to physical facts {fact:2,3,6}.

claimDavid Chalmers argues that because philosophical zombies are conceivable, they are logically possible, though this argument is controversial.
claimDavid Chalmers supports the irreducibility of conscious experience by appealing to conceivability, arguing that conscious experience can always be 'abstracted away' from reductive explanations, as evidenced by the logical possibility of philosophical zombies, which are exact replicas of a person that lack conscious experience.
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.
perspectiveDaniel Dennett labeled David Chalmers a 'reactionary' and described the invocation of philosophical zombies as 'an embarrassment,' arguing that the thought experiment relies on a 'hunch' and begs the question.

claimPhilosophers Susan Schneider and David Chalmers proposed a thought experiment where a silicon-based computer might be behaviorally identical to a neural-based brain but lack subjective consciousness, a concept they refer to as a "philosophical zombie."
Hard problem of consciousness - Wikipedia en.wikipedia.org 1 fact
claimDavid Chalmers, Joseph Levine, and Saul Kripke argue that philosophical zombies are impossible within the bounds of nature but possible within the bounds of logic, implying that facts about experience are not logically entailed by physical facts and that consciousness is irreducible.
