This is a handy little book that sets out, predominantly, some reflections by Searle on the nature of consciousness and the implications for free will. Its value lies in its clear and tight positioning of consciousness as a good subject for enquiry. Philosophy has, as it were, come of age and we need to discuss consciousness not as a matter of semantics or because we cannot be sure it exists in the first place. Rather, we must operate on the basis that it is there right enough and it needs an explanation, because after all that explanation will have practical consequences.
