How can human experience, vibrant with colours, sounds, flavours, emotions and meanings, arise from the skeletal dance of matter depicted in the physical sciences? Today the mind-body problem confronts not only metaphysicians and moral philosophers, but also workers in the fields of cognitive science, artificial intelligence and neuroscience. Paul Marshall offers a radical solution to the mind-body problem by rejecting the idea of a purely material world and asserting instead the primacy of experience. As many have recognized before, experience is not reducible to material bodies and processes alone. Marshall goes a step further and suggests that the matter investigated by modern science corresponds to structural features of an experiential universe that supports and includes our familiar experiences. Utilizing clues furnished by mystical experience and responding to a challenge posed by the physics of motion, Marshall takes up Leibniz's philosophy of 'living mirrors' and arrives at a holistic world-picture that has suggestive links with quantum physics and the visionary cosmologies of East and West.
