How, when, what threshold, or is there even a quantitative, or perhaps qualitative property required for the seemingly enormous "transition" where a system which is considered to be "Conscious" become aware that it is "Conscious?"
Any form of being Conscious, as this is irreducible, must merely be part of a response to phenomenon, is a subset of that response applicable to, I suggest, a loop within that response. It is integrated within consciousness through the specific irreducibility of consciousness. In this the phenomenon carries the material for self-consciousness.
