I'd agree with the "all of the activity in our bodies, including the brain, can be explained by ordinary chemistry" statement. That 30 different chemicals can temporarily supress consciousness suggests, to me, that consciousness is the outcome of a complex interconnected system. (I'm sure one can think of dozens of "different" interventions that would anesthetize a computer.)What is interesting to me is that consciousness is not a binary property either among people or across species. Among people, we can see that natural variations, the assaults of aging, and chemical impairments modulate the amount of consciousness. And the more we study animals, the more examples we uncover of animals doing things that we thought only humans could do (tools, language, grammar, planning, play, ethics, deviousness, empathy, etc.). Humans have more consciousness stuff than other animals, but we're less unique than we think. Consciousness is probably more an outgrowth of our large amounts of brain tissue (relative to body size) than some special property of that tissue.That said, its unclear to me that any rational being of human proportions can explain human-level consciousness without hitting an analog of the Tristram Shandy paradox
