We are grieving the recent loss of Walter Bradley, a longtime Fellow of the Center for Science and Culture at Discovery Institute and namesake of the Institute’s Walter Bradley Center for Natural and Artificial Intelligence. So today, out of our archive, we bring you the first half of Robert J. Marks's 2020 interview with Walter Bradley, co-author of the seminal 1984 intelligent design book The Mystery of Life’s Origin. The book is now available in a revised and expanded edition with updates from multiple contributors discussing the progress (or lack of it) in origins science in the 35 years since the book’s original publication. In this first of two podcasts, Bradley discusses the history of the attempts to explain life’s origin naturalistically, and how the three authors of the 1984 book came together to shake up the world of origin-of-life science. This is Part 1 of a two-part conversation.
