This book presents the most recent debates by leading contemporary philosophers of enduring themes and issues concerning the question of God's existence. William Craig and Antony Flew met on the 50th anniversary of the famous Copleston/Russell debate to discuss the question of God's existence in a public debate. The core of this book contains the edited transcript of that debate. Also included are eight chapters in which other significant philosophers - Paul Draper, R. Douglas Geivett, Michael Martin, Keith Parsons, William Rowe, William Wainwright, Keith Yandell and David Yandell - critique the debate and address the issues raised. Their substantial and compelling insights complement and further the debate, helping the reader delve more deeply into the issues that surfaced. In the two final chapters, Craig and Flew respond and clarify their positions, taking the debate yet one step further. The result of these many contributions is a book which provides the reader with a summary of the current discussion and allows one to enter into the dialogue on this central question in the philosophy of religion.
