Thorny problems with Molinism #4: the internal contradiction between CCFs & PAP

tl;dr

Molinism tries to eat its cake, and still have it too, by incorporating both CCFs and PAP. But if counterfactuals of creaturely freedom are true, then the principle of alternate possibility is necessarily false, and vice versa.

Continued from part 3, on how God can know what people will do

Now that I’ve canvassed some exegetical and theological problems with Molinism, I’m going to move on to a philosophical one—a contradiction which issues between two Molinist beliefs:

  1. If a free person (Ali), a general food-lover, were in some Circumstance where she had to choose between chocolate and cheese, then she could choose either one (this is the principle of alternate possibility, PAP).
  2. God knows that if Ali were in the Circumstance, then she would choose chocolate (this is the counterfactual of creaturely freedom, CCF, for Ali in the Circumstance).

There are a couple of important things to understand about (1), so you can see how this contradiction arises:

So the Molinist believes that when Ali gets to the Circ­um­stance, she really could choose chocolate, and she really could choose cheese, and there is nothing that determines this choice except her own will at that moment. But this seems to put him in a bind…

A thought-experiment to illustrate the problem

Imagine God creates a million worlds, all identical up until the Circ­um­stance. If Ali really can choose either chocolate or cheese, we would expect some percentage of these worlds to diverge from the others at the moment of her choice. In some of the worlds, Ali would choose chocolate; and in others, history would proceed identically up until the Circumstance, and then Ali would choose cheese. Maybe in 853,302 worlds she would choose chocolate, but then in 146,698 she would choose cheese. Or whatever. What we would expect to see is that in some percentage of worlds her choice goes one way, and in some percentage it goes the other.

We’d expect this because both chocolate and cheese are live options for Ali. She really can choose otherwise than chocolate—even out of character and against all other influences. So if she only ever chooses chocolate, even in a million identical worlds, this would be overwhelming evidence that cheese is not, in fact, a live option. There would seem to be something necessitating her choosing chocolate, and preventing her choosing cheese. That outcome would be indistinguishable from determinism, which the Molinist repudiates.

Now, leaving aside the well-worn worry that this some-worlds-chocolate-some-worlds-cheese scenario looks like mere chance rather than a responsible choice, here is how the problem plays out:

  1. God wants to create only one world;
  2. He wants it to be a world in which Ali will choose chocolate;
  3. The way he ensures Ali will choose chocolate is by actualizing the Circumstance in which she would choose chocolate;
  4. But…the Circumstance in which she would choose chocolate is identical to the Circumstance in which she could choose cheese.

You probably see the obvious contradiction inherent in (iv). But let me try to draw it out a bit:

Problem How can God “pick out” the chocolate world to create, and distinguish it from the identical cheese world? What could conceivably “privilege” the one over the other, given that there is nothing to distinguish between them with respect to how Ali will choose?

This isn’t an easy problem to get your head around, so let me riff on it some more. Refer back to item (2) near the beginning, which says that in the Circumstance, Ali would choose chocolate. How can this be true? God plans to create just one world identical to the million he created in the experiment above. Those worlds were all identical at the moment of the Circumstance, yet Ali still chose cheese in some of them. But then, in the single world God plans to create—which is precisely the same as these other worlds—there must be some chance that Ali would choose cheese.

But if there is some chance she’d choose cheese in the Circumstance, it simply cannot be the case that she would—as a matter of 100% certain fact—choose chocolate.

Remember: this is not a matter of what Ali does choose once God actualizes the Circumstance. Obviously if he went ahead and actualized the Circumstance, then he would know what Ali chooses—because then she would actually decide on chocolate or cheese, and he would have free knowledge of this event.

The problem is with the hypothetical or possible world God is thinking of creating, as opposed to any actual world which he does create. It looks like the Molinist is simply trying to eat his cake, and then still have it too. He is saying that:–

Summary Ali both (a) would certainly and (b) would not necessarily choose chocolate in the Circumstance.

But (a) and (b) are formally contradictory to each other. They cannot both be true.

The Molinist’s dilemma

It seems the Molinist has to either throw out the counterfactuals of creaturely freedom, or the principle of alternate possibility. Either it must be false that Ali would choose chocolate in the Circumstance, or it must be false that she could choose cheese. The problem is, either horn of the dilemma completely skewers Molinism. You cannot have Molinism without both of these doctrines:

This isn’t the place to delve into the philosophical intricacies of each horn of this dilemma; suffice to say it presents a very thorny problem for Molinism indeed, and one to which I can see no solution. Molinism appears to be stillborn.
