1) Those most certain consciousness is purely neurological are encouraged by developments in AI. Some believe when the right algorithms are combined with sensitivity, computing ability and memory, it will eventually result in the self-aware aspect of consciousness. Actually, they think complexity is the key, and guess what? They can’t get a computer to stop acting like a computer. If the proper level of complexity is what’s needed, then shouldn’t the best AI programs already be showing some sort of self awareness? Even snails seem to have the self-aware aspect (as primitive as it is) because one can observe them asserting their will. Surely AI is currently able to produce a program as complex as snail awareness, and therefore demonstrate a computer with will. Put it on wheels, give it a system for initiating self-propulsion, and then show us a willful computer equaling, say, the willfulness of a snail. That is a very simple test of the physicalist theory of consciousness.
2) So far, it ain’t happening primarily because of one wrench stuck in the works: repetitiveness. It’s not the presence of repetitiveness that’s the problem (yes, living and conscious processes are full of repetitiveness); the problem is the inability of non-living physical operations to
escape repetitiveness, which the physical processes associated with life, and functions associated with consciousness both do with ease (e.g., as manifested respectively in evolution and will). That computer on wheels above, for instance, might move around, but it will only “repeat” its programming, and will
never escape it (and random variation programmed in isn’t “will”).
3) Thus physicalist theories for origin of life and consciousness share a common nemesis (mechanistic repetitiveness). So at least one physicalist skeptic asks for a small but very specific bit of evidence before expressing faith in physicalism. When asked for such evidence, all we hear is what physicalness
can do, while the evidence being requested is what matter
CAN’T be shown to do. The evidence isn’t to show that matter can self-organize itself for a few steps or be coaxed (by
conscious chemists) to combine into highly complex molecules. The test isn’t to show that a computer can “think.” The two tests are: 1) demonstrate the potential of chemistry to progressively self-organize on its own (no, not into life, just show the ability to perpetually organize in harmony with the environment), and 2) demonstrate that any sort of physical construction can exhibit will. Very modest requests if you ask me.
