It seems to have come down to a choice between “nothing is conscious” and “everything is conscious.” But materialism becomes incoherent when it requires us to believe that we only imagine we are conscious — that’s a basic error in logic.
Egnor: It’s sobering to note that neuroscience has utterly failed to explain how the brain and mind relate. It is as if cosmology had failed to tell us anything meaningful about the universe; or medical science failed to tell us anything about health and disease; or geology failed to tell us anything about rocks.
But first, wait a minute.We do not really know what consciousness is. That is true whether or not “our intelligence and our experiences are ineluctable consequences of the natural causal powers of our brain, rather than any supernatural ones.” as Christof Koch claims.
