This is called God's "free knowledge" and it contains the future or what will happen. In between God's natural and free knowledge is his middle knowledge (or scientia media) by which God knows what his free creatures would do under any circumstance.[1]:31 These are "truths" that do not have to be true, but are true without God being the primary cause of them. In The Internet Encyclopedia of Philosophy, John D. Laing has provided an example of middle knowledge: "If John Laing were given the opportunity to write an article on middle knowledge for the Internet Encyclopedia of Philosophy, he would freely do so."[2] This viewpoint is difficult for some to grasp but is the basis of Molinist opinion.
