God and Freedom
God and free will are frequently placed side by side as compatible ideals. I want to argue that god’s existence is incompatible with free will. I will do this by looking at the notion of divine foreknowledge, and how this affects our freedom.
To begin with, we must define god. As Anselm said, “God is that of which nothing greater can be thought:” an omnipotent, omniscient, and omnibenevolent being. For our purposes, we are primarily interested in the reaches of god’s knowledge. Such knowledge must be infinite, unrestrained by any boundary. If we limit god’s knowledge, then the entity of which we speak ceases to be called god. Before we even reach the subject of freedom, though, problems arise. This model suggests that god knows for certain what he will do in the future. This is problematic, because god then lacks the power to change his future mind. God’s power becomes limited by his infinite knowledge. In a sense, god loses his own freedom. This conflict between omniscience and omnipotence might suggest that we need to refine our definition of god.
I would argue, however, that god’s internal inconsistencies are unimportant. Having been defined as an infinite being, the precise details of his workings can lie beyond our grasp. It makes sense that as finite beings, we will perceive some contradictions. In other words, god is all-powerful and all-knowledgeable; he’s free to be paradoxical when he likes.
The application of divine foreknowledge to human freedom is more interesting. Suppose I am presented with two choices, A and B. If I have free will, it’s anyone’s guess as to which one I will choose. However, god already knows, before I decide, which option I will select. This isn’t a matter of belief on god’s part; it’s necessarily a matter of absolute certainty. If god knows for certain that I will choose B, then A was never really a genuine option. Because of my very limited knowledge, A appeared to be a possible choice when in fact it was not. If my future “choices” are laid at god’s feet in crystal-clear certainty, it’s impossible that my “choices” are freely made.
This is somewhat in conflict with common sense, as we experience ourselves as being free. This is because it is for all practical purposes impossible to know, as an omniscient god must, what the future holds. We may follow a predetermined course, but we are unaware that we do so.
It might be argued that this conflict between free will and god can be solved by invoking god’s incomprehensibility, as we did to reconcile infinite knowledge with infinite power. This tactic doesn’t seem to me to be applicable in this case. Previously we had an internal inconsistency, in which pieces of our incomprehensibly great being, god, were in conflict with each other. Here, the inconsistency is not internal. Free will is not a given as were infinite knowledge and power. In other words, god can appear to contradict himself, because we have limited understanding of him, but other simpler things like free will cannot contradict god, particularly when such things aren’t made logically necessary.
There is one problem with this: Free will is necessary to solve the problem of evil. In this model, god can in essence see the future, complete with all its evil acts. This raises the question of why, as an omnibenevolent entity, he doesn’t interfere. I would argue, however, that this problem is also present if we have free will. God would be responsible for our having free will, and by extension what we do with it; god is still ultimately responsible for evil acts wrought by mankind. The problem of evil is present both in the free will and deterministic models.
Here, we can either revise our definition of god, or our definition of free will. We could argue, for instance, that god does not in fact know what the future holds. This argument might involve the impossibility of certainty regarding future events. Perhaps future events are truly ambiguous right up until they happen, and have no inherent truth value beforehand. Omniscience, then, would have to be redefined as the possession of all possible knowledge.
This does not appear to me to be a promising tack. By modifying god’s omniscience to exclude future events, we are turning god into a limited entity. As we have already established, limitation of god is incoherent. Perhaps we could argue that future events appear to be necessarily ambiguous to us, but to apply the same restriction to an infinite being seems an improper move.
Another possible reconciliation of god and freedom, titled “middle knowledge,” was proposed by Molina in the 16th century. Laing offers this summery:
The theory of middle knowledge presents a picture of divine omniscience which includes not only knowledge of the past, present and future, but also knowledge of conditional future contingents (propositions which refer to how free creatures will choose in various circumstances), counterfactuals (propositions which refer to how things would actually be if circumstances were different than they are or will be), and counterfactuals of creaturely freedom (propositions which refer to what a free creature would have chosen (freely) to do if things had been different).
However, it seems to me that middle knowledge merely pushes the issue back a step. God still knows what I’ll do in any given situation. We are still left with a scenario in which the outcomes of what we call choices are already known by an omniscient god. Perhaps god freely chooses which scenarios to actualize, but the outcome of my own choices remains fixed in god’s omniscience.
Another line of reasoning might suggest that divine foreknowledge does not in fact force future events, but merely coincides with them. Rudavsky sums up a response:
[It has been] suggested that the analysis of God’s foreknowledge follows that of human knowledge in that both involve belief states. Divine knowledge, however, unlike its human counterpart, is infallible. Hence the phrase “God foreknows p” can be unpacked as
2.1 God believes p in advance of the occurrence of p
2.2 p is true
2.3 God is incapable of error
The crucial part of this analysis is 2.3, that is, the emphasis upon God’s infallibility. It is God’s infallibility, coupled with his prior knowledge, rather than the causal force of his knowledge, which carries with it the suggestion of the necessity of the objects of his knowledge.
This analysis seems to me to be correct. In other words, it is the fact that god is incapable of error that brings with it the future as he has foreknown it.
To conclude, it appears that the reconciliation of god and freedom is a difficult project indeed: Divine foreknowledge seems to prevent human freedom. I’ve argued that various tactics of joining the two, including Molina’s concept of middle knowledge and curtailing god’s omniscience, are ultimately unpersuasive.
