I argue that the vulgar belief in continued and distinct existences, as Hume describes it in Treatise 1.4.2, “Of Scepticism with Regard to the Senses,” is defeasibly justified. Prior to and apart from the rebutting defeater that Hume brings forward as an argument from perceptual relativity in paragraphs 44 and 45, the vulgar belief is perfectly in order, philosophically speaking. For Hume, a belief is defeasibly justified if and only if it is produced by permanent, irresistible, and universal principles of the imagination. The vulgar belief meets these conditions and thus is defeasibly justified—even though it suffers eventual defeat.

Hume is justly famous for his criticisms of theistic proofs. However, what is less well-known is that Hume also criticized the claim that belief in God, simply because it is natural, is justified without supporting argument. Hume certainly encountered this claim in his own Protestant milieu, as various textual clues throughout his corpus indicate. His own endorsement of natural beliefs raises the possibility that religious belief might be justified without argument. One of Hume's chief aims in The Natural History of Religion was to show that religious belief is not natural in a way that makes it justified without argument
