William of Ockham proposed that the spiritual and secular worlds were different, since the former was "above rationality, and the latter was merely rational.

Explanation:

Ockham proposed that human reason could attain some truths without the need of universal concepts, which means that each individual mind could create concepts of things. However, the mind cannot know some truths about the human being, except through revelation which is given by God and not through human reason. So the spiritual order is above rational reasoning, while the secular order is in the realm of human reason.
