 Natural theology is, roughly, the effort to establish the existence and nature of God by arguments that in no way depend on the contents of a purported revelation. But is it even possible for human beings to come to know God apart from revelation? Scotus certainly thinks so. Like any good Aristotelian, he thinks all our knowledge begins in some way with our experience of sensible things. But he is confident that even from such humble beginnings we can come to grasp God.
