SD Hagen’s An Alternative to Believing in Nothing is both a personal journey and a public invitation to explore the philosophy of Deism, a belief in a non-intervening Creator, grounded in reason, nature, and science rather than organized religion. Hagen introduces Deism as a third path for the spiritually curious who are disillusioned with traditional religion but not ready to settle for atheism or agnosticism. Through a blend of memoir, history, and practical guidance, he presents Deism as a meaningful alternative for modern seekers, especially those among the “nones,” the fast-growing segment of religiously unaffiliated adults in the U.S.

I was taken in by the honesty of Hagen’s storytelling. He opens up about loss, fatherhood, and the spiritual vacuum left by a nonreligious upbringing. There’s a gentleness to how he lays out his path toward Deism. There’s no lecturing, no dogma, just a guy trying to make sense of things. It felt genuine. His curiosity is contagious. I appreciated how he didn’t shy away from emotion, and the way he wove historical facts about figures like Jefferson and Paine into his story gave his ideas more weight. At times, I found myself highlighting entire paragraphs, not because they were particularly poetic, but because they were refreshingly clear and grounded.

The section on religious survey data, while informative, slowed the momentum. I understand why it’s there though, it builds the case that there’s a large audience who might connect with Deism, but I wanted to get back to the philosophy and personal insights because I found them to be the most interesting aspects of the book. The writing style is conversational and accessible, which works well overall, though occasionally it leans into a presentation deck tone. Still, Hagen’s passion for reason and spiritual openness kept me flipping pages.

I found this book to be a thoughtful and hopeful read. It’s ideal for people who feel adrift spiritually but aren’t ready to give up on meaning altogether. I’d recommend it especially to late bloomers, people going through big life transitions, or anyone raising kids and wondering how to pass on values without dogma.
