What position are you taking? (Genuine question.) Do you believe humans are conscious because of a special property we have? If you are a dualist, how do you explain the interaction in physical space between the non-physical special property and the physical brain?
I do. God. I am partial to and bullish on the brain being a quantum-classical computer. There has been interesting research exploring that recently [0, 1, 2, 3]. That (quantum mechanics) seems to be escape-hatch, so to speak, from the otherwise deterministic, mechanical procession of the universe.
