Religion as belief, a realist theory: a commentary on Religion as Make-Believe, A Theory of Belief, Imagination, and Group Identity

Van Leeuwen's Religion as Make-Believe, A Theory of Belief, Imagination, and Group Identity argues that religious and political beliefs are fundamentally different from mundane, factual beliefs and represent a cognitive attitude more akin to imagining. To ground this difference, Van Leeuwen proposes four principles defining factual beliefs: 'involuntariness' mandates that people cannot choose what they believe; 'no compartmentalization' says that factual – but not religious – beliefs guide behavior in all domains; 'cognitive governance' requires that inferences be readily drawn from factual beliefs; 'evidential vulnerability' entails that beliefs are revised given contradictory evidence. While factual beliefs are supposed to meet these standards, Van Leeuwen marshals evidence that religious and tribal beliefs – or "credences" – fail to obey these four principles. In this commentary, I argue that beliefs – both factual and religious – are often much more complicated than Van Leeuwen assumes. This complexity makes perfect conformity to the four principles unlikely, even for factual beliefs. I review Van Leeuwen's evidence for credences and suggest that this evidence is compatible with the null hypothesis: that religious beliefs are simply beliefs.
