This book is a must read for anyone who wishes to consider the "religious life" in a "non-traditional/post-foundationalist" sense. Roberts argues, and rightly so, that Nietzsche raises profound questions regarding the nature of religion and the uses of traditional religious language/metaphor. Further, in his discussion Roberts brings to light the significance of Nietzsche's (unexpectedly) ascetic life style. My only hesitancy is that Roberts seems to stop short of arguing that Nietzsche was indeed a deeply religious thinker. I believe this stronger argument could have been made, though the author limits himself with the less ambitious aim of using Nietzsche to raise questions about what we mean by "religion." My rating = 4.5 stars.
