Is your mind more than just your brain? Does the soul actually exist? These questions have been pondered for millennia. What does the latest scientific research suggest? On this ID The Future, renowned neurosurgeon Dr. Michael Egnor begins a conversation with host Andrew McDiarmid about his new book The Immortal Mind: A Neurosurgeon's Case for the Existence of the Soul. Egnor makes a powerful case that our capacity for thought, reason, and free will points to something beyond mere brain function. After defining important terms, Egnor begins exploring the compelling evidence he has gathered across four decades of practice in neurosurgery. Along the way, Dr. Egnor also boldly challenges the Darwinian view of the mind's evolution, arguing that abstract thought and free will are immaterial and could not have arisen through natural selection. This is Part 1 of a two-part conversation.
