Questions about how to negotiate belief and unbelief in social and public spheres are attracting an increasing amount of attention from scholars in a range of disciplines, and from concerned members of the public. This volume directly addresses the emergence of New Atheism and delves into the developing "Spiritual but not religious" (SBNR) phenomenon. Avoiding simplistic accounts of atheism, and of religious belief, an international panel of contributors provide readers with insights into a wide range of nuances within theism and a-theism, as well as spiritual practice and faith. Chapters cover, among other topics, Christian atheism, re-enchantment with nature, oral arguments against theism and atheist aesthetics. This collection reaches beyond Christian belief and unbelief, which is so often the milieu of atheism debates, and incorporates a range of traditions as well as the emergence of SBNR. As such, it will be of keen interest to scholars of the Philosophy of Religion, as well as Religious Studies and Theology more generally.
