Experiencing knowingly experiencing - it's not just that there 'be something that it feels like to be that' but that there be the potential for it to feel like itself knowingly, that is to be a centre of consciousness or a point of view. But an experiencing doesn't truly know itself, since the possibility must also be that it prove to have been a different kind of knowing all along - as in the analogies of waking from a dream, or that on 'waking up' there is the 'realisation that you've always been awake', etc. If everything is consciousness then if an experiencing A comes to be understood as produced or caused by an event B (say, the unconscious, or the brain) then the experiencing can transform (without necessarily changing in its essential qualities) into the experiencing as B, where B becomes the point of view. Without something like this there is no justification for asserting that all is consciousness. But if you, as A produce something C which is subject-like, say a work of art, or even a child, do you consciously inhabit C? No, although there can be a fantasy of it. In any case the idea that all is consciousness goes against this most basic experience of difference, that your creations make their own way.
