Marcel Danesi is a master of weaving different disciplinary threads, from linguistics to history and psychology. His book, that creatively links metaphors, riddles, and the origin and development of language, is a clear expression of this talent. -- Yair Neuman, Ben Gurion University of the Negev This is an extremely thoughtful and provocative book which attempts a very different answer to the question of the origins of language. Language is a system that allows us to think and reflect on the world as well as a system designed for cooperative social action. It is this cooperative social action as the basis for coordinated hunting, and ultimately social learning, that is customarily highlighted in evolutionary accounts. Danesi turns things on their head, recognizing the importance of metaphor in human cognition and then focusing on riddles, like the Riddle of the Sphinx, perhaps one of the earliest riddles, as a form of social action and as a mechanism for highlighting and cementing the role of metaphor in thinking and consciousness. This is a highly original book, scholarly, thoughtful and at times brilliant-highly readable and provocative (in the best possible way) throughout. -- Geoffrey Beattie, Edge Hill University.
