Before it was Mental Immunity, it was Unhinged. Then two things happened: Amarosa Manigault stole my title and good friend Lee McIntyre helped me understand the importance of centering the concept of mental immunity. Lee's counsel initiated a painstaking overhaul of the book, but it was the best advice I ever got.
OK, so it's not a book. But my 2014 essay about reason and faith did win the Selma V. Forkosch Award for outstanding contribution to the freethought literature. Thank you, Council for Secular Humanism!
This book was a self-published guide to critical thinking. It came with "Theseus," software I designed for diagramming the logic of arguments and clarifying the questions that animate thinking. My startup company, Knosis, offered the package to homeschoolers. I sold the company in 2007.
This is a book about western philosophy's attempts to articulate an adequate standard of reasonable belief. It's more technical than Mental Immunity, but also more academically rigorous. It may some day prove to be of interest to professional philosophers, but I have yet to find a publisher for it.
