 A related debate concerns whether natural theology is the only method by which we can have access to the domain of truths about supersensible realities of religious interests. Some practitioners (call them rationalists) argue that only propositions that can be justified by unaided human reason are candidates for permissible belief. Others (call them hybridists) allow that our natural faculties can take us a certain distance—to knowledge of the basic nature and even existence of God, say—but argue that we must ultimately appeal to revelation and faith when it comes to more specific doctrines regarding the divine nature, acts, and intentions. This is the canonical Roman Catholic position on faith and reason developed in authors such as Augustine, Anselm, Aquinas, and revived in the natural scientific context of the Renaissance by Catalan scholar Raymond Sebond (1385–1436). Sebond’s Latin work, Theologia Naturalis (1434–1436), became famous when Michel de Montaigne translated it into French in 1569 and made it the subject of the longest of his renowned Essays (‘Apology for Raymond Sebond’), in 1580.
