>How does a brain, consisting of many modules, create just one person? The same way a population, consisting of many people, creates just one state? The state is not the people and the people are not the state, yet both exist.

But a state isn't conscious

See Eric Schwitzgebel, "If Materialism Is True, the United States Is Probably Conscious", http://faculty.ucr.edu/~eschwitz/SchwitzAbs/USAconscious.htm

In other words, you have absolutely no idea if a state experiences "consciousness" in the philosophical sense, so instead have claimed that it doesn't simply because it is too different from you to receive the benefit of the doubt, even though you recognize that such an assertion is impossible within an empirical framework.

Sure... but it's just as impossible to make a claim that it does.

Except that it's not. The assertion made was that any empirical definition of consciousness that applies to humans would likewise apply to states. This is a straightforward claim.

If you dispute this claim then all you need to do is provide an empirical definition of consciousness that applies to humans but not states. I will note that defining "consciousness" as something like "the human experience" is vacuous and doesn't count.

Dualism is wholly wrong. There is no mind-body split. Even speaking of 'the brain' is just a rough convenience. Individual neurons stretch from that tangled mass of them up in your skull all the way down your spine and to the soles of your feet. Every nerve fiber extends from nearly every point in your body right into your brain. Perception pours in from every point, and it is all extremely important. Emotion, for in…

I would point out that metaphysically speaking, we have no way of knowing if we are in a simulator. For all we know, the universe could be just the matrix. However it is self evident that our conscious thoughts and experiences exist. This indicates that there is a clear conceptual distinction between our consciousness and the material world in which it resides.

Consciousness is an incredible thing. Reducing it to a mere property is akin to pretending it doesn’t exist at all.

By what metric do you make that declaration? I submit that any empirical model of consciousness applies equally to states as it does to human minds.

That’s exactly why I think empirical models of consciousness fall short.

I agree that they do, because the experience of consciousness, what one might call the very kernel of our being in order to separate it from any medical definition, can only be measured subjectively, excluding it empiricism by definition.

However, if you are saying that the inability to construct a model of consciousness that does not apply equally well to states and people is a failure of empiricism, I think you have started with the conclusion and are looking for justification.

A lot do. E.g. Tononi's IIT.

Let me rephrase. No one here said that complexity is consciousness. In particular, AnIdiotOnTheNet, who you replied to, did not say that complexity is consciousness. Also, tangentially, New York's sewers aren't that complex compared to even a rat's brain.

Not directly. If not complexity, is it a kind of computation or something physical that makes neurons produce consciousness? Those positoins are more tough to support.

What is the magic measure and what is magic threshold using that measure?

What about a future city's sewer system that is complex enough?

> Just removing patterned sensory input from a typical person via sensory deprivation quickly results in their consciousness dissolving. Do you have any basis for this statement?

He's likely talking about https://en.wikipedia.org/wiki/Isolation_tank

I’m not sure what your intent is here. “Sewers are conscious” seemed to be a reductio ad absurdum but now you seem to be arguing that complexity is consciousness. Regardless, I haven’t proposed any mechanism for consciousness to arise so I don’t have any “position to support” there.
