 is well-known for his arguments against physicalism, or reductive materialist accounts of consciousness according to which all facts about consciousness fit into a completely physical account of the world. His view (at least in his classic, 

) is called 'naturalistic dualism', according to which consciousness, while part of the natural world and so compatible with a scientific worldview, is not reducible to physical properties. 

• If Chalmers explicitly claims he now holds a physicalist view of consciousness, whether in a publication (peer reviewed or not, article, commentary or blog) or in an interview, this market resolves YES. 

• If by 2025 Chalmers has not explicitly so endorsed physicalism, or still explicitly argues for a view that is logically inconsistent with physicalism, it resolves NO. 

I will continue clarifying criteria as questions arise.
