The curious fact about the consciousness debate is that in spite of the absence of a physical theory
There is a physical theory, and it has been presented over a hundred times in this thread alone.
among the proponents of Strong AI, this doesn't seem to be even relevant.
Non-sequitur.
Physics is treated as a sideline to the combination of computing and philosophy.
Completely wrong. Information theory is a physical theory.
This is so deeply ingrained that anyone pointing out that there is no physical theory of consciousness is accused of all kinds of strange evils
Like being wrong.
mysticism, dualism and irrationality.
Perhaps those as well, but certainly wrong.
The reaction is perhaps because the truth is so obvious.
And wrong.
There is no physical theory of consciousness, and we know this because the physicists aren't talking about it.
You have no idea whatsoever what a physical theory is, do you? Why on
Earth do you think physicists should be talking about consciousness?
The germ theory of disease is a physical theory. Evolution is a physical theory. Do physicists study these?
Why is there no physical theory?
There is. You're wrong.
Mostly because the real-world definitions aren't tight enough.
Your definitions are entirely absent. Ours work just fine.
The theory of computation is in essence mathematical.
Wrong!
Mapping a computation onto a real world process is easily done, but expressing the computation in a physical sense is another matter.
That's information theory.
It's not that computation is difficult to find in the universe - rather, it's universal.
In some senses, yes.
In a physical sense, the components of a computer thrown on the floor are performing computation just as much as a working machine.
Completely wrong in every respect.
Again, I put to you the simple question: If you take a couple of million transistors, diodes, resistors and capacitors, and a few hundred miles of wire, and just dump them all on the floor, do you get a working computer?
Why or why not?
No. It's a series of unfounded, logically unconnected, and for the most part, flat-out factually untrue assertions.
The supposed materialists, trying to devise a theory that makes man nothing special, have ended up putting man right at the heart of their theory.
Wrong.
They restrict consciousness to a tiny area of the universe.
Wrong.
Unknown anywhere but where life exists - but then capable of being manufactured in the simplest of machines.
Consciousness is unknown anywhere except where consciousness exists. Yeah. What a surprise.
It is, I suppose, possible, that consciousness is a physical property which is inextricably linked to life.
That is completely unrelated to
anything we have said.
But we don't yet know that, and it seems a rash assumption that it cannot exist under other physical configurations.
We have pointed out repeatedly that it does exist in non-living systems.
Since you have completely failed to respond to any of the other points in the argument, it is not all that surprising that you also miss the most important one.
