 In this article, we aim to avoid most the more recent complexities but also explain their origins by focusing on some central developments in the early modern period that helped to frame contemporary natural theological debates. We are focused here only on theoretical arguments (both a priori and a posteriori or empirical ones). It is controversial whether moral arguments are also part of natural theology, but we set them aside here (see also the entry on  God, arguments for the existence of: moral arguments).
