In this knowledgeable work, Junker-Kenny examines the turn to religion in Habermas' latest work calling for a process of mutual translation of religion and postsecular reason. She traces this back to his early engagement with religion and the later chastening of religion in discourse ethics. She lucidly presents the major philosophical objections to the founding concepts of Habermas' reasoning, welcoming the called-for alliance of theology and postsecular reason against the 'pathologies of modernity'. The book is a thorough systematic reconstruction and a groundbreaking source for the dialogue between theology and philosophy.
