Van Huyssteen searches for an epistemology that can bring theology and science into a productive relationship. He discusses at length the very different views of Stephen Hawking and Paul Davies and asks what it might mean that we human beings seem to carry the spark of rationality that provides the key to our understanding the universe. In the end, Van Huyssteen focuses on evolutionary epistemology, which reveals the biological roots of all human rationality. Recognizing these roots, he proposes, can lead to a more comprehensive approach to human knowledge and to a graceful interdisciplinary duet between theology and the sciences.
