Questions about how to negotiate belief and non-belief in social and public spheres are attracting an increasing amount of attention from academics in a range of disciplines, and from concerned members of the public. This volume addresses the emergence of ’new atheism’ and the developing ’spiritual but not religious’ phenomenon. Avoiding simplistic accounts of atheism, and of religious belief, it provides readers with insight into a wide range of nuances within theism and atheism, as well as spiritual practice and faith. The chapters by an international panel of contributors focus on topics such as: a typology or cartography of atheisms and agnosticism; contrasting types of atheism within Christianity and Buddhism; questions about cognitive and doxastic stances in atheisms; theist rejections of and atheist embracing of ’God’; and atheist aesthetics. Reaching beyond the Christian tradition, the book will be of particular interest to scholars of the philosophy of religion, as well as religious studies and theology more generally.
