The Vagueness of Religion

Abstract

A concept is vague if it admits of borderline cases—cases in which it is not clear whether the concept applies. Thus vague concepts are concepts without sharp boundaries. I argue that religion is vague, and I draw conclusions from this claim for both framing up conceptions of religion and studying it. One result will be to undermine arguments to the effect that any account of religion that does not sharply demarcate the religious from the nonreligious is somehow defective. Another will be that admitting the existence of borderline cases relieves us of the obligation to seek high levels of precision in our various usages of the term. And a third will be that is it not at all clear that any periods of human history can be characterized as times “before religion” on any but the narrowest of definitions.
