Luke Martin is joined by neurosurgeon, war veteran and author Dr Lee Warren for a powerful and deeply personal conversation on trauma, grief, the brain, and whether we can truly change how we think and live. After performing over 200 brain surgeries in a warzone in Iraq, Lee returned home carrying the unseen wounds of PTSD. Years later, following the devastating loss of his son, he found himself confronting not just suffering, but the limits of a purely material understanding of the mind. In this wide-ranging discussion, Lee explores the difference between brain and mind, why neuroscience alone may not explain consciousness, and how our thoughts can literally reshape our brains. Drawing on cutting-edge research, clinical experience and his Christian faith, he makes the case for what he calls “self brain surgery” — the idea that we can intentionally rewire our thinking to change our lives. They discuss PTSD, grief, near-automatic thoughts, anxiety, ADHD, neuroplasticity, and the role of faith in recovery. Lee also reflects on suffering, the reliability of our emotions, and why learning to question our thoughts might be one of the most important skills we can develop. A profound and practical conversation at the intersection of neuroscience, psychology and faith — and a hopeful vision for anyone feeling stuck, overwhelmed or defined by their past.
