Abstract
I present a persistent religious moral theory, known as divine command theory, which conflicts with liberal political thought. John Rawls's notion of public reason offers a framework for thinking about this conflict, but it has been criticized for demanding great restrictions on religious considerations in public deliberation. I argue that although Paul Kurtz is critical of organized religion, his epistemological suggestions and ethical theory offer a feasible way to build common moral ground between atheists, secularists, and theists, so long as each maintains the important democratic value of toleration in the form of either fallibilism or skepticism.
