Matter and Consciousness is a terrific introduction to the philosophy of consciousness, and a surprisingly light read. Churchland's writing is clear, concise, and fresh - that is to say, not boring.
The first half of the book investigates the phenomenon of consciousness, discusses it's philosophical difficulties, and covers the main philosophical theories of consciousness. The second half is dedicated to investigating intelligence in general, and Churchland explains how science (namely, AI and Neuroscience) is involved in this investigation.
This balance of philosophy and science makes the book readily accessible, and will appeal to a broad audience. Comprehensive yet concise, Churhland's book is the perfect introduction to the trippy world that is conscious thought.
