The hard problem of consciousness might be unravelled through quantum mechanics. In quantum’s double slit experiment, light particles are proven to act differently under observation. When observed, they appear to travel as one might expect, like a bullet. They go through one slit. When not observed, the data shows that the particles now travel in a wave, going through both. Science now speculates on quantum consciousness.
However some scientists suggest consciousness is not a product of the brain, being of a different order. Monist theory question the existence of matter. It reckons consciousness primary, matter doesn’t exist without perception. See the videos on the belief page for discussion. Indeed it is a hard problem, is consciousness a product of the brain? We are most interested in matter, but certainly the non material world exists. Consciousness, like the atom, is stuff of the universe.
