Worship is the feeling or expression of reverence and adoration for something. The attitude of worship towards God or gods or ancestors is a universal of human culture. But why do we worship? Do objects of worship need to fulfill certain criteria? Does worship play a positive or negative role in human culture? Is it clear that a perfect, omnipotent and omniscient God truly wants to be worshipped? Some pagan religions worship the earth, or the aspects of nature that make human life possible and rewarding. Does this make more sense than worshipping an imperfect God? The Philosophers express their reverence with Daniel Speak from Loyola Marymount University.

We seem to be able to decide our behavior for ourselves – what we do is up to us. But if everything that we do can be explained by physics, does this leave room for freedom? Are all of our actions pre-determined? Are we slaves to fate? Is freedom compatible with determinism, or does science teach us that we're nothing but complex machines, following out a complicated program that a good enough physicist could have predicted centuries ago? And what are the implications for morality and responsibility? John and Ken exercise their will with Manuel Vargas from the University of San Francisco.

Are there levels of reality, with each level emerging from the other in a way that provides a truly new aspect of reality? The concept of emergence has been seen as an alternative to mere reducibility in discussion of the relation of the physical world to the biological world, consciousness, the social world, and God. Ken and John probe the nature of reality with Tim O'Connor, Professor of Philosophy at Indiana University and author of "Theism and Ultimate Explanation.:

What is the relationship between the mind and the brain? Monists believe that there is only one substance or property in the Universe, be it physical (Materialists) or mental (Idealists). But Dualists, like the 17th Century French philosopher Rene Descartes, hold that mental stuff exists side by side with physical stuff. Can this view be defended, in light of modern science? John and Ken probe the mind-body with David Rosenthal from City University of New York, author of "Consciousness and Mind."

Many religions tell us that God is perfect: all-knowing, all-powerful, and beneficent. Why then do bad things happen? John and Ken discuss the problem of evil with their guest, Michael Tooley from the University of Colorado at Boulder, co-author of "Knowledge of God."

The philosopher Saint Augustine of Hippo is one of the most important figures in the history of Christianity. His efforts against the Manichean, Arian and Pelagain heresies shaped the fundamentals of Christian doctrine. His "Confessions" tells the story of his own conversion from Manicheanism to Christianity. His philosophical ideas anticipated Saint Thomas Aquinas and Descartes. His three-volume City of God remains a classic of Christian apologetics. And many find the roots of some of the darker sides of Christian doctrine, from the emphasis on original sin to the second-rate status for women, in his works. John and Ken welcome Georgetown University Provost James O'Donnell, author of "Augustine, Sinner & Saint: A New Biography."

What does "God" mean? Is God a concrete thing like a chair or a human; or is it an abstract thing, like love or goodness? Is there something that all concepts of God have in common, some feature that all cultures attribute to God? Richard Swinburne, Emeritus Nolloth Professor of the Philosophy of the Christian Religion at the University of Oxford, joins John and Ken to explore the many ways in which people across the world conceive of the divine.
