This final episode explores why Deism rose with Enlightenment reason yet faded by the early 19th century. From philosophical critiques by Hume and Kant to the emotional force of the Second Great Awakening, Deism’s rational, non‑intervening God struggled against revivalism, Romanticism, political backlash, and its lack of organized community. Though it later blended into Unitarianism and modern secular thought, its purely intellectual appeal couldn’t compete with movements that spoke to the heart. I also reflect on my own attempt at Spiritual Deism—a balance of reason and mystical experience—and why that journey now leads me toward a new project merging Deism with Buddhism. Thank you for joining me on this path. My new project can be found at Bodhideism.org
