Can intelligent design make a positive, testable scientific case—or is it merely a criticism of Darwinian evolution? Luke Betzner welcomes mathematician, philosopher, and intelligent-design theorist William A. Dembski, Ph.D., Ph.D., M.Div., for a wide-ranging discussion of how scientists detect the effects of intelligence in nature. Dembski explains the logic of design inference, distinguishing induction, deduction, and inference to the best explanation. Drawing on examples from SETI, forensic science, archaeology, molecular biology, information theory, genetics, medicine, and paleontology, he argues that intelligent causation can be investigated rigorously and can generate testable expectations. The conversation examines biological codes, molecular machines, the origin of life, natural selection, the Cambrian explosion, orphan genes, information density, and the once-dominant idea of “junk DNA.” In this episode What makes the case for intelligent design positive rather than merely critical How intelligence is detected in SETI, forensics, archaeology, and biology Induction, deduction, abduction, and inference to the best explanation DNA, RNA, proteins, biological codes, and the origin of life The limits of natural selection and evolutionary time The Cambrian explosion, common ancestry, and the fossil record Design-based predictions about function, “junk DNA,” and orphan genes Why intelligent design can guide productive scientific research Chapters 00:00 Welcome to Paratus 00:26 Luke Betzner introduces William A.
