No. The configuration of elementary particles that makes an atom is not the same configuration of elementary particles that makes consciousness. So I don’t see why you think that my argument implies that an atom is conscious. Why do you think that?
We already agreed that the difference between any two configurations is only ever quantitative. So if brains are conscious (which they are), and the difference between brains and non-brains is only quantitative, then non-brains should also have a quantity of consciousness.
Agreed. Lets be more specific though. An object that collects data from its environment, process it, then responds by reacting to that environment, is conscious. Agreed?
If you are talking about a physical object: all physical objects ever do is that their elementary particles interact according to the fundamental forces in space and time. That is true for any computer also. So while you may talk about a computer as if it “processes”, “collects data”, etc., in reality they do not do that anymore than rocks and atoms do. Both rocks and computers are merely collections of particles that interact.
