 Molina claims that God’s providential control over the world involves middle knowledge in a crucial way. Very briefly, here is how it is supposed to work: through natural knowledge, God knows what is necessary and what is possible. Through middle knowledge, God knows what every possible person would do freely in every possible situation, among other things. So God decides which kind of world to create, including those situations in which free human persons should be placed, knowing how they would respond, and this results in God’s free knowledge (contingent truths which are up to God), including foreknowledge of the actual future.
