The hard problem of consciousness would remain as a harder problem of consciousness. Those theories which maintains that the subjective conscious experience arises from brain is not so hard problem as it was presented by David Charmer who argued for the problem. David also further argue that the problem consciousness belongs a altogether a different realm of reality which is completely different from the physical reality. With respect to the consciousness research, the physical reality is largely confined to the brain. Many theories has been around the understanding that everything that we experience or everything that we attribute to consciousness can be explained using the brain itself, there is no necessity of any third parameter to explain our conscious experience or consciousness. However, we have not been successful so far to explain any of the phenomena.
There could be two assumptions:
brain is physical whereas the consciousness belongs to a different reality which is unknown .
In such situation the problem of consciousness can only be solved in conscious reality, it can't be solve in any other realm which are characteristically less than conscious domain. Therefore, it is impossible to solve or understand the problem of consciousness using brain.
