But why, first of all, is this subject a significant one? And why does it appear especially pertinent at precisely the present moment? To begin with, growing numbers of “religious nones,” that is, people who have limited or no religious affiliation yet still claim to believe in some kind of divinity, signal an unprecedented shift in the American religious landscape, and many scholars who have sought to understand this phenomenon have indicated that something like “spirituality” might capture an important aspect of their outlook, if not their “identity.” We, for our part, certainly agree that this is a socially significant shift. Yet we also note that much of the interpretation and ensuing discussion about the “religious nones” draws upon and continues to assert uninvestigated understandings of religion and spirituality, where we would argue that the shifts underway should elicit some reconsideration of the terms that are deployed to analyze and interpret this allegedly “new” phenomenon.
