Um, I think you are confusing me with you. Your claim is that “once God has predicted that Tyrion will choose A there is no possible world in which Tyrion actually chooses B.”
My claim is the contrary. There are possible worlds where Tyrion chooses A, and possible worlds where Tyrion chooses B.
In which case your position is inconsistent. To be clear you said “He (God) states what exactly will happen in the future”. So you specifically stated that God’s prediction WILL be correct (a statement that you repeat below) but you also state that it is possible for Tyrion to choose contrary to God’s prediction.
Lets walk you through this step by step. What happens is as follows:
- Tyrion asks God “Am I going to choose A or B?”
- God says “you’re going to choose A”
- Tyrion makes his decision.
The question is, at point 3 where Tyrion is making his decision is he able to choose B.
If your answer is that God’s prediction MUST be correct (in other words there are no possible worlds in which Tyrion chooses B at this point) then Tyrion has NO CHOICE. It is simply logically impossible for him to choose B.
If your answer is that Tyrion can choose A or B (in other words that there ARE possible worlds where Tyrion chooses B at this point) then the thought experiment Tyrion has created is set in one of the possible worlds where he does indeed choose B and therefore we must assume God’s prediction was incorrect.
You see now, it is meaningless to state that Tyrion COULD choose contrary to God’s prediction but WON’T because that is outside Tyrions thought experiment. You might as well just replace Tyrions question with “what’s two plus two” and point out that God can correctly answer that question.
Your phrase above, that I enclosed in quotes, is confused. There is no change in possible worlds “before” and “after” God has predicted. Possible worlds are possible worlds. They include both time and space, so how could they change over time?
Many worlds theory is a tool for showing alternative POSSIBLE futures or histories each representing a “world”. Thus far you have argued both that there are and that there are not possible worlds in which Tyrion chooses contrary to God’s prediction. Thus your position is inconsistent.
In some possible worlds, Tyrion chooses A, and God predicts A. In some possible worlds, Tyrion chooses B, and God predicts B. There are no possible worlds wherein God predicts incorrectly, since God is omniscient.
Ahh maybe this is where you have been going wrong. You see you’ve got things out of sequence. In this thought experiment God’s prediction comes BEFORE Tyrion’s decision. Not afterwards. That would be a very silly thought experiment indeed. It would be like a weather forcaster who can only predict yesterdays weather.
I know, I know, you want there to be a possible world wherein Tyrion listens to God and successfully disproves His prediction, but that is not a possible world. You overestimate Tyrion’s power, and underestimate God’s, which is absurd, since God is also omnipotent.
Frankly I don’t care which argument you pick, but progress thus far has been flipflopping between two contradictory positions with steadily increasing speed. And trying to claim that between them God can do the logically impossible. It’s a bit silly but not something that concerns me unduly.
Let us be clear, here. You are referring to your scenario wherein Tyrion’s new knowledge limits the possible worlds. I understand possible worlds a little better, so I know that is absurd.
Er, no. It’s you who is saying that there is no possible world in which Tyrion chooses B after God predicted A. Oddly it is also you who is arguing that there ARE possible worlds in which Tyrion chooses B after God predicted A. Mostly you are just arguing with yourself here, I’m just providing a running commentary as you do so.
It is categorically impossible that God could find Himself unable to express particular knowledge, whether about the future, the present, or the past. God knows everything and God can do anything
So how would he correctly answer the question “what answer will never be given to this question?” It’s designed to be logically impossible to answer correctly, despite the existence of perfectly valid answers. So how could God provide me with that piece of particular knowledge?
No. I explained the real reason why, and you wish to demonstrate another point which, as it turns out, is not valid.
If this is the case then why not try writing out a CONSISTENT argument which shows it, instead of just repeating an assertion that it is so.
You are arguing that it is impossible for an omniscient being to demonstrate some particular knowledge. I am saying that is absurd, not it’s not impossible, it is easily done. You stipulate, “God would need to be able to (as a minimum) correctly answer any and all valid questions which are asked of him.” But here, you contradict yourself, because, “which will I choose, A or B,” is a valid question, whereas, “What answer will you not say?” isn’t.
Both questions are valid. In one case there is a single correct answer (which is contingent upon and inverse to whatever answer is given), which God is being asked for. In the other there are an infinitely large number of correct answers (like some mathematical equations) which God is being ask for one of.
However, in neither case is God able to correctly provide a correct answer. I’m not sure why you are struggling with this so much, but I’ll walk you through step by step if you need it.
