Science does indeed know "what consciousness is". Perhaps you've been listening to silly old non-scientist David Chalmers, who believes in magic? His entire schtick is ignoring the fact that consciousness can be (and has been) fully explained from a neurological standpoint. You don't need spooky magic for consciousness. In fact, your initial response to me applies far more to Chalmers's unscientific ramblings than to the observable, empirically-verified description of the mechanism of consciousness that has been established over decades of scientific research.
