Daniel C. Dennett is one of a handful of leading unbelievers. He is a scientist who questions the existence of God. The New York Times considered Consciousness Explained "one of the ten best books of the year." Dennett writes clearly and interestingly. Even very religious people will benefit by reading his books, for he raises questions that people need to answer. People should not sit back passively and watch life pass before them like a entertaining TV program. Every religious book and every philosophy book that is worth reading teaches that people have an obligation to be active, to develop themselves and improve society. Dennett's books inform people how the human body works, in this case, consciousness and unconsciousness. He addresses the question, how is it possible for material, the human body, to think?
