Despite the advances in neuroscience and the rapidly extending capacity of computers, we still have no adequate theory of consciousness. No account of how the brain is able to create experience. And no account of how the material stuff of the brain can be responsible for thought.
Should we conclude that consciousness cannot be explained in terms of the physical? But if so what is the alternative? Or is it just a matter of time, and one day an AI machine will miraculously find itself experiencing the world, and its mere components will have soul?
World-renowned physicist Roger Penrose, metaphysical idealist Bernardo Kastrup, and philosopher of neuroscience Elizabeth Irvine go head to head on the origins of consciouness.
