>It comes from electrochemical reactions in your brain This isn't an explanation. None of it answers the interesting questions. How and why do computers work? Well they are made of atoms and run on electricity. They do useful work and we call it computation. This is all true and important to understand, but it is filling a slot that needs to be filled with things like computability theory. I'm not sure what was meant by nonphysical property, but many materialists disagree over whether consciousness can be copied like a text, or is necessarily destroyed as a book is.
