Which is to say that whenever there is (a physical arrangement with) a logical structure that matches (is transitive with) the logical structure of consciousness—then there would be consciousness.
Um, no? Why on Earth does that follow? We postulate that there is something about the physical properties of carbon atoms arranged as a human brain that causes, or is, consciousness. The physical properties of your line on paper aren’t anything like that.
Then the quantum amplitudes and current flows are still nothing like that of a conscious brain. The logical structure only exists in your head; the atoms in my desk have some sort of “logical correspondence” to the ones in my head, for sufficiently arbitrary assignments of representation. “This atom corresponds to that one, and this one to that one over there… so the desk represents my brain.” Well, it can, but only in my head!

If it’s a pencil line then it’s got carbon atoms ;-)
Yes, but they’re not organised anything like the ones in the brain! The energy flows, binding energies, wave amplitudes are completely different.
So what if I take an ink made of neural steam cells, and some other stuff to keep them alive and not connecting to one another?
