Spiritual, but not religious?: On the nature of spirituality and its relation to religion

Recent years have seen a rise in those who describe themselves as “spiritual, but not religious”. At a popular level, there has been a lot of debate about this label and what it represents. But philosophers have in general paid little attention to the conceptual issues it raises. What is spirituality, exactly, and how does it relate to religion? Could there be a non-religious spirituality? In this paper, I try to give an outline account of the nature of spirituality and of religion, and then close with some thoughts on the prospects for a non-religious spirituality.
