Contemporary atheism usually conceives religion as centered on a core of statements, each of them designed to correspond to the cosmic facts. Classic anthropological and sociological studies of religion often start in a different place with practices attending to the multi-dimensional character of religious life. Worlds change when people revise their ideas about the boundaries of objects or about how to classify things together or what is the normal course of a process. The chapter introduces notions of fictional truth that might be extended directly to notions of mythical and religious truth. It presents the idea of the permanent progressiveness underlying strong ethical truth, suggests introducing more stringent demands on a notion of mythical truth. Religious truth includes mythical truth, but isn't exhausted by it. There are many dimensions of religious practice, and statements play other roles besides the telling of stories or the recounting of lore.
