The scientific observations that you are thinking of are those which fail to account for the difference between personal level awareness and sub-personal awareness. Sure, if you erroneously assume that personal consciousness is definable only as a single logical path of instructions, and then fail to consider that the lower levels of neuronal activity could also be the product of sub-personal consciousness, then, like the stop-motion video, the natural urge to draw a false chain of causality from bottom to top becomes hard to resist. If the top level consciousness were in fact dictating awareness to the bottom some of the time, the scientific observations would look exactly the same. How could it look any different? > If a subjective experience is supervenient on the > underlying physical process It is not supervenient. The science does not make that conclusion inevitable at all. Supervenient means one way. Since we can control a single neuron from the top down, that means that that neruon's behavior is being dictated by the collective activity of other neurons - which, as far as we know, can only be yoked together by subjective intent at the personal level. In my view, the more likely explanation is that there is not one underlying physical process, there are physical descriptions on multiple levels, each with corresponding *ranges* of a single phenomenology. The personal range is only one level, and it does nor correspond to cellular process most of the time, nor does it correspond to evolutionary process either. Personal awareness corresponds to a experiences within a human lifetime. The lifetime is the fundamental phenomenon, not the physiology or the genes or the ego. > then the observable brain changes can all > be attributed to this underlying physical process. Of course, they would have to be because you are using physical instruments for your physical body. Again, it's the stop motion video. If we only look at half of the story, we can invent the other half to match it, and it will make sense, but not for the universe that we actually live in, which is not the universe the stop motion measurements imply. > If not, then the > observable brain changes cannot all be attributable to the underlying > physical process; i.e., a miracle will be observed.

Exactly! That's why mechanism fails even at locating consciousness. If behavior can exist without awareness, then what difference does it make whether the body is the size of a cell or a person? It's still ontologically impossible for us to be having this conversation in a universe of only unconscious behaviors. > No > account of consciousness is needed in explaining the weather either, > even though for all we know, weather patterns have associated > subjective experiences too alien for us to guess at. > Right, that's what I'm saying. We cannot internalize these weather reports and neuroscientific reports as the private truth, because they are completely inappropriate. Not only is it superimposing a public model on private physics, it is superimposing a microphysical mosel on a macrophenomenal presence. You cannot build New York City based on statistical vector models of pedestrian traffic.

There is no scientific support at all for limiting consciousness to what can be measured by inanimate objects. To the contrary - we *are* the instrument which reports a billion times more accurately on what (who) 'the brain' really is than any kind of primitive, molecule counting medical device.
