The central argument in The Singing Heart of the World is that human reason occupies the pivotal position which science claims for it, but that the scientific endeavor itself penetrates insufficiently deeply into the human encounter with reality, and is on this account inadequately rational. The book begins with an overview of the universe that science has unfolded for our contemplation and response, and ends with the argument that future humanity can thrive only through the unfettered exercise of reason allied with virtue and grounded in faith in a God who is now seen to be utterly greater than the smaller Gods of a more restricted view of reality.
