He did not know that as a settled future fact, because man had not been created yet and Adam had not yet chosen.
The future doesn't exist as a settled reality sitting somewhere for God to observe. God cannot know something that does not exist. Before creation, Adam did not exist. His choice did not exist. His choice had not yet been made.
God knew it was a possibility for Adam to disobey, because He created him with the capability of doing so. But until Adam took a bite of the fruit of the Tree of the knowledge of good and evil, his action was not "necessary."
The answer is, quite simply, yes, if that foreknowledge is infallible.
There's nothing complicated about this.
Let T stand for some future act, such as “you answer the telephone tomorrow at 9 a.m.” The Stanford Encyclopedia of Philosophy lays out the basic argument this way:
(1) Yesterday God infallibly believed T. [Supposition of infallible foreknowledge]
(2) If E occurred in the past, it is now-necessary that E occurred then. [Principle of the Necessity of the Past]
(3) It is now-necessary that yesterday God believed T. [1, 2]
(4) Necessarily, if yesterday God believed T, then T. [Definition of “infallibility”]
(5) If p is now-necessary, and necessarily (p → q), then q is now-necessary. [Transfer of Necessity Principle]
(6) So it is now-necessary that T. [3,4,5]
(7) If it is now-necessary that T, then you cannot do otherwise than answer the telephone tomorrow at 9 am. [Definition of “necessary”]
(8) Therefore, you cannot do otherwise than answer the telephone tomorrow at 9 am. [6, 7]
(9) If you cannot do otherwise when you do an act, you do not act freely. [Principle of Alternate Possibilities]
(10) Therefore, when you answer the telephone tomorrow at 9 am, you will not do it freely. [8, 9] |
The problem here is not "causation," but rather "necessity."
I agree that knowledge of an action, by itself, does not itself cause the action.
But if the knowledge of the action is infallible, then that knowledge cannot be wrong (by definition), and so there is no possible alternative, because any alternative would falsify that knowledge.
Thus, if God infallibly knew that Adam would sin before he existed, then Adam's sin could not fail to happen. If Adam could have chosen not to sin, then God's prior knowledge could have been false. But if God's knowledge could not be false, then Adam could not have chosen otherwise.
Either God knew Adam's "choice" in advance, and I put choice in quotes because at that point it isn't one except in name only since Adam could not do otherwise, or Adam did have a real alternative, and God's knowledge of future free choices is not exhaustive and infallible.
If Adam could obey, then Adam’s disobedience was not infallibly settled beforehand. If Adam’s disobedience was infallibly settled beforehand, then Adam could not obey.
Saying “God only knew what Adam would freely choose” does not solve it, because if God infallibly knew Adam would choose sin, then choosing otherwise was impossible. Calling the impossible alternative “free” does not make it meaningful.
A free choice requires that the alternative be genuinely possible. Exhaustive infallible foreknowledge removes that possibility by making the outcome settled before the creature even exists.
