"The Universe That Hopes" is a trilogy of three books: "3 Theories of Everything", "How Do You Know That?" and "Comprehensive Spirituality". 3 Theories of Everything compares three different worldviews or ways of understanding reality. "How Do You Know That?" is about four fundamental ways of knowing or relating to reality: through the Bible, Rationality, Experience and Institutions. "Comprehensive Spirituality" is about having a unified or wholistic understanding of the natural and supernatural parts of reality.
