If consciousness is a fundamental property of reality, as David Chalmers and other philosophers/physicists speculate, does this mean that many of the ontological problems in philosophy would be solved? For example, the problem of universals or the existence of fictional characters. After all, both "redness" and "Sherlock Holmes" and the "number 11" exist in consciousness.
Based on this argument, "God" could be nothing but consciousness itself and all things could exist in it, and nothing could exist outside of it.
Are there any philosophers who have addressed this argument or is this reasoning logically wrong and not worth pursuing?
