Many senses can be derived from consciousness, true self-reference is neither necessary nor sufficient. I think that the big deal about consciousness is not that it has true self-reference but that it is able to care about itself its world that a non-trivial, open ended, and creative way. We can watch a movie or have a dream and lose self-awareness without being unconscious.

I think that humans have developed a greater sensorimotive capacity as a virtuous cycle of evolutionary circumstance and subjective investment. Just as hardware development drives software development and vice versa. It's not that we are conscious as opposed to unconscious, it's that our awareness is hypertrophied from particular animal motives being supported by the environment and we have transformed our environment to enable our motives. Our seemingly unique category of consciousness can either be anthropic prejudice or objective fact, but either way it exists in a context of many other kinds of awareness. The question is not why we are conscious, it is why is consciousness possible and/or why are we human. To the former, the possibility is primordial, and the latter is a matter of probability and intentional efforts. > > > > >> Consciousness is not explainable in term of any parts of something, > >> but as an invariant in universal self-transformation. > >> If you accept the classical theory of knowledge, then Peano > >> Arithmetic > >> is already conscious. > > > Why and how does universal self-transformation equate to > > consciousness? > > I did not say that.

You can't water a real plant with simulated water or survive the arctic burning virtual coal for heat. If you look at substitution level in reverse, you will see that it's not a matter of making a plastic plant that acts so real we can't tell the difference, it's a description level which digitizes a description of a plant rather than an actual plant. Nothing has been simulated, only imitated. The difference is that an imitation only reminds us of what is being imitated but a simulation carries the presumption of replacement. > > > Human > > consciousness exists nowhere but through a human brain. > > Not at all.

My whole point is revealing a universe description in which logic and direct experience coexist in many ways. Limiting it to logical language defeats the purpose, although I would love to collaborate with someone who was interested in formalizing the ideas. Logic is a 3p language - a mechanistic, involuntary form of reasoning which denies the 1p subject any option but to accept it. The 1p experience is exactly the opposite of that. It is a 'seems like' affair which invites or discourages voluntary participation of the subject. Half of the universe is made of this.
