Herb Silverman's personal website serves as a valuable hub for secular advocacy and freethought discourse. As a mathematician-turned-activist who famously challenged South Carolina's constitutional ban on atheists holding public office, Silverman brings both intellectual rigor and real-world experience to his writing. The site features his extensive collection of essays, books, and speaking engagements that address church-state separation, secular ethics, and atheist identity with wit and accessibility. His work with the Secular Coalition for America and various humanist organizations lends credibility and depth. While the site design is straightforward rather than flashy, the content is substantive and historically significant for the secular movement. An excellent resource for those interested in American freethought activism and its evolution.
