This article proposes an underappreciated value for traditional natural theology and its familiar arguments for the existence of God, without endorsing the soundness or the rational cogency of these arguments. Famously, Aquinas and Kant represent two extremes, with Aquinas endorsing some natural theology arguments for God’s existence and Kant opposing such arguments. This article recommends a moderating approach, on the grounds that while Aquinas is unduly optimistic here by the epistemic standards of many inquirers, Kant is too pessimistic regarding the heuristic value of the relevant natural theology arguments. The neglected heuristic value of these arguments, according to this article, is in their prompting in unique ways some challenging and fruitful questions for inquiry about God. The disputed natural theology arguments have not achieved anything near a consensus on their soundness or rational cogency, but they still can have significant heuristic value aside from their soundness or rational cogency. This article identifies the relevant fruitful questions and their theoretical importance for human inquiry about God. Ultimately, a heuristic interrogative approach to familiar arguments of natural theology gives these arguments a new role with resilient heuristic value for inquiry about God, even if they do not justify the belief that God exists. Such moderation, this article contends, is rationally defensible with regard to these arguments.
