The Hard Problem of Consciousness and Ananda

The hard problem of consciousness is supposed to be about our own personal feeling of the world. This is as far as I, or anybody, understands it, that peculiar cast that the generic experience of red for example has. Yes but isn’t that problem a subsection of the main problem of how the cerebral events translate into an experience of red as such? Talking about neural correlates has embedded in it the assumption that we know that this neuronal traffic ‘is’ red. This is what Stephen Earle Robbins calls the coding problem.

Three dots represents S in Morse code. This is the convention. How do we know ‘red’ before we know it. It’s an unknowable convention so to speak.

Are Plato’s forms and the substantial forms of Aristotle an attempted solution to the problem of conscious experience? The upadhis (limiting adjuncts) are proposed by Advaita. If we knew what consciousness was such that experience is possible would that bring an alteration to experience as such? Shankara says no and insists that it is a matter of insight. Would, however, the cast of general experience alter and the hard problem now be the source of ananda (bliss)?
