In which it is argued that Molinists are determinists, but this is not to their shame.
Robert Kane is one of the world’s leading experts on the philosophy of free will. He’s the editor of The Oxford Handbook of Free Will and one of the contributors to Four Views on Free Will (Blackwell, 2007). He’s written dozens of articles on the subject of free will. So it’s safe to say he knows whereof he speaks when it comes to debates over free will.
Kane is an incompatibilist, which is to say, he believes that determinism is incompatible with free will (at least, the kind of free will needed for moral agency). But what is determinism? Here’s how Kane explains the term in his book A Contemporary Introduction to Free Will:
An event (such as a choice or action) is determined when there are conditions obtaining earlier (such as the decrees of fate or the foreordaining acts of God or antecedent causes plus laws of nature) whose occurrence is a sufficient condition for the occurrence of the event. In other words, it must be the case that, if these earlier determining conditions obtain, then the determined event will occur. (pp. 5-6)
In more familiar terms, we say that a determined event is inevitable or necessary (it cannot but occur), given the determining conditions. If fate decreed or God foreordained (or the laws of nature and antecedent causes determined) that John would choose at a certain time to go to Samarra, then John will choose at that time to go to Samarra. Determinism is thus a kind of necessity, but it is a conditional necessity. A determined event does not have to occur, no matter what else happens (it need not be absolutely necessary). But it must occur when the determining conditions have occurred. If the decrees of fate had been different or the past had been different in some way, John may have been determined to go to Damascus rather than to Samarra. Historical doctrines of determinism refer to different determining conditions. But all doctrines of determinism imply that every event, or at least every human choice and action, is determined by some determining conditions in this sense. (p. 6)
Now here’s an interesting (to me) and perhaps surprising (to you) observation: According to Kane’s understanding of determinism, Molinism is clearly a species of determinism. (To use Kane’s phrase, it is a “doctrine of determinism.”) For according to Molinism, God has an infallible decree; God foreordains all things, including human free choices. As the Molinist will be quick to insist, God foreordains on the basis of his middle knowledge, that is, his knowledge of the counterfactuals of creaturely (libertarian) freedom. God “weakly actualizes” a possible world by creating agents with libertarian freedom and arranging their circumstances such that they freely choose what he has planned (on the basis of his middle knowledge) for them to choose. But the fact remains that on the Molinist scheme, despite its commitment to libertarian free will, God has an infallible decree and foreordains whatsoever comes to pass. As one prominent Molinist explains:
Not only does this view make room for human freedom, but it affords God a means of choosing which world of free creatures to create. For by knowing how persons would freely choose in whatever circumstances they might be, God can, by decreeing to place just those persons in just those circumstances, bring about his ultimate purposes through free creaturely actions. Thus, by employing his hypothetical knowledge, God can plan a world down to the last detail and yet do so without annihilating creaturely freedom, since God has already factored into the equation what people would do freely under various circumstances.
Thus, according to Molinism, if God has foreordained that Sam mows the lawn next Saturday, then Sam will mow the lawn next Saturday. God’s act of foreordination is a sufficient condition for Sam’s action (P is a sufficient condition for Q if Q necessarily follows from P) and therefore, according to Kane, Sam’s action is determined by prior conditions, namely, God’s act of foreordination. (Notice that Kane explicitly includes “the foreordaining acts of God” among his examples of determining conditions.)
