I find the idea of a "physics of consciousness" specious. The presumption is that we can analyze and perhaps explain consciousness scientifically and I must question that.

Every scientific explanation is an exercise in reductionism, are we to assume that consciousness can be reduced? what if it cannot be?

Can we claim to understand something that cannot be reduced? This is really a comment about the interplay of science and epistemology. But if consciousness cannot be reduced then it cannot be explained (in the scientific sense) and so perhaps we should consider this.
