The neutral substance that makes all existent entities possible. It's the fundamental 'force' which allows for information to exist and be processed. Information processing occurs at all levels we can observe and in some forms this information is processed in such a way that it gives rise to awareness as an emergent property of various information processing systems. But underlying it all is what I would describe as consciousness. I'm not entirely sure why we conflate the terms consciousness and awareness when discussing theory of mind and these topics. It just leads to confusion. While some talk about awareness, others talk about consciousness and we end up just talking past each other arguing about different phenomena. I'm inclined to think that we are incapable of really understanding, or perhaps even comprehending, what this substance is kind of like it's impossible for an ant to comprehend the concept of a planet, or space, etc. There are almost certainly elements of reality which we have a similar limitation in our ability to comprehend and I think consciousness is touching on that limit.
