  Above we explained several features of Reid's epistemology and his foundationalism relevant for understanding his analysis of the rationality of belief in God. Reid's case on behalf of the rationality of belief in God follows from his critique of Cartesian and Humean foundationalism, which required foundational beliefs to be justified by reasoning. According to Reid, foundational beliefs do not require proof of their own through argumentation. He writes, “Their evidence is not demonstrative, but intuitive. They require not proof, but to be placed in the proper point of view” (EIP 1.2, 42). Reason is not the “only judge of truth” (IHM 6.20, 169). Besides, human reason itself is fallible (EIP 2.22, 244–5). Reason is not necessary for epistemic justification, a fact that situates Reid's theory of empirical knowledge in the externalist camp.
