Reprising and expanding on themes introduced in "Why This Universe: God, Cosmology, Consciousness, and Free Will" (2014) this book focuses on the metaphysical implications of causal closure and explores those implications for consciousness and free will in a causally closed physical universe. Like the earlier work, it takes science's discovery of causal closure seriously. It also supposes that God might be real and then investigates the connection between them as this can be inferred from the nature and contents of human consciousness and historical experience.
Among the more troubling phenomena we, that is human beings, experience is the seeming genuineness of what philosophers call a "libertarian free will". In the course of this book, the author argues that free will is a fact and that its nature and existence is best understood by virtue of its contrast with causal closure in the physical. Along the way the nature of life and consciousness, human and animal, are investigated and fit into the same contrast between the purposefulness of free will and the purposelessness of physical mechanisms.
