In his latest work Ian Barbour tackles some of the thorniest issues posed by contemporary thought. He offers astute analyses of the shape and import of evolutionary theory, indeterminacy, neuroscience, information theory and artificial intelligence. He also addresses deeper philosophical issues and the idea of nature itself. Then with characteristic clarity and verve, Barbour advances to the interconnected religious questions at he core of contemporary debate: Are humans free? Does religion itself evolve? Are we immortal? How does God act in nature?
