This is the context:
So, in principle, with a brain connectivity map we would have a vast trove of objective data about the brain, and with our own introspection, we have a vast trove of subjective data about consciousness. One might think it would then be possible to abstract out the relevant kinds of principles that connect the objective to the subjective. I don’t think this would mean that we would bridge the mind/brain gap, but we would have boiled down this conundrum to the simplest possible principles.
