"In Vigilant Faith: Passionate Agnosticism in a Secular World, Daniel Boscaljon takes up the contemporary challenges to faith by skepticism and secularism. He proposes a model of faith for believers and unbelievers alike--a passionate agnosticism--that is rooted in a skeptical consciousness. Skepticism and faith are structurally similar, he writes, in that they share an "unknowing" quality. The author argues that vigilance--the act of keeping watch, a spiritual practice in its own right--is as necessary a precondition for the structure of faith as it is for the structure of skepticism. A suspension in uncertainty and an openness to possibility require vigilance, he attests, if faith and skepticism are to avoid the often dogmatic tendencies of both theism and atheism to cling to their own brands of certainty and knowledge."--Publisher website.
