Metaphysics of Consciousness opens with a development of the physicalist outlook that denies the need for any explanation of the mental. This inexplicability is demonstrated not to be sufficient as refutation of physicalism. However, the inescapable particularity of modes of consciousness appears to overpower this minimal physicalism. This book proposes that such an inference requires either a wholly new conception of how consciousness is physical or a deep and disturbing new kind of physical inexplicability.
