GOD AND DESIGN Is there reason to think a supernatural designer made our world? Recent discoveries in physics, cosmology, and biochemistry have captured the public imagination and made the design argument—the theory that God created the world according to a specific plan—the object of renewed scientific and philosophical interest. Terms such as “cosmic fine-tuning,” the “anthropic principle,” and “irreducible complexity” have seeped into public consciousness, increasingly appearing within discussion about the existence and nature of God. This accessible and serious introduction to the design problem brings together both sympathetic and critical new perspectives from prominent scientists and philosophers including Paul Davies, Richard Swinburne, Sir Martin Rees, Michael Behe, Elliott Sober, and Peter van Inwagen. Questions raised include: • What is the logical structure of the design argument? • How can intelligent design be detected in the Universe? • What evidence is there for the claim that the Universe is divinely fine-tuned for life? • Does the possible existence of other universes refute the design argument? • Is evolutionary theory compatible with the belief that God designed the world? God and Design probes the relationship between modern science and religious belief, considering their points of conflict and their many points of similarity. Is God the “master clockmaker” who sets the world’s mechanism on a perfectly enduring course, or a miraculous presence continually intervening in and altering the world we know? Are science and faith, or evolution and creation, really in conflict at all? Expanding the parameters of a lively and urgent contemporary debate, God and Design considers the ways in which perennial questions of origin continue to fascinate and disturb us. Neil A.Manson is Visiting Assistant Professor of Philosophy at Virginia Commonwealth University in Richmond, and a former Gifford Research Fellow in Natural Theology at the University of Aberdeen. He has a long standing interest in the science and religion debate.
