It's irrelevant how omniscience is defined in Christianity because here omniscience is the claim under investigation.
Not that its relevant here but the only claim I've made is a belief in the omniscient Christian God.
You've set the stage by narrowing the claimed Gods that others believe in specifically down to that Christian God. So, your claim is dealing with the Christian God specifically.
What claim have you made you might wish to ask since anti-theists love to claim they make no claims and therefore the onus is on the theist to prove whatever?
That claim is that omniscience cannot be logically coherent. In order for us to discuss a potential proof or disproof of such a claim it is imperative that we understand what is meant by the terms involved.
For instance. The ignorant will often come up with foolish contradictory statements like "If God can't create a rock big enough that he can't lift it then he can't be all powerful because there is something that God cannot do."
These things stem from an ignorant understanding of what is meant by God, specifically the Christian God when we speak of God.
In order to avoid these misunderstandings and the accompanying waist of time it IS imperative that we understand our definitions.
And that means the mere assertion of omniscience is insufficient.
I agree. Your mere assertion that omniscience is not logically sustainable is insufficient for the discussion. You must demonstrate why such a term as specifically defined is logically unsustainable. Remember your own argument, we are not trying to prove that any particular thing with omniscience actually exists in reality. What I've tried to show is that omniscience can be logically sustainable. You should be trying to prove that it isn't. You've simply posed a question that may not even be realistically meaningful.
Yet until the supporters of omniscience can explain how God knows there's nothing [he] doesn't know [he] doesn't know, mere assertion is all there is.
I've given you some propositions and examples. I've yet to get your counterpoints to these in order to further the discussion.
Perhaps I'm getting you mixed up with another poster...I'll go back and reread. Maybe you should as well?
IF its supporters can't answer the question, How does God know there's nothing [he] doesn't know [he] doesn't know? Otherwise okay until some other problem may arise.
Um...okay? But I've answered your question - not definitively since I cannot prove such things- and have shown how omniscience is logically coherent. Do you or can you comment on my propositions instead of relying on your question to be the answer or not?
No. You're pitching omniscience's mere assertion against a logical problem that arises from the assertion.
No I'm "pitching" a proposal that either you've misunderstood what is meant by omniscience in Christianity, how it relates to logic, and the fact that you've not commented on my potential solutions to your problem.
Your asserting that there is a logical problem but you've not demonstrated that God can't know everything that is possible to know and you've not demonstrated whether or not your question is meaningful given the definitions of the terms involved.
The answer to your question may be as self evident as "How do you know you are self aware?". Or as meaningless as asking "What color is an invisible purple rock?".
Can you show that your question is logically sustainable?
As I've repeatedly made clear here, to isolate that question and examine it on its own, I've stated that the existence of the bible God is a given for this purpose.
Yes! And as I've repeatedly made clear here, because of your givens you've opened yourself up to the same standard of proof as what your question asks for. You've made a claim. You've not demonstrated proof of that claim but ask for proof against that claim. Let me give you a comparison....
Believer: God exists because I don't know how the universe | Unbeliever: Omniscience is logically unsustainable because I got here otherwise. | don't know how God could know what he doesn't know.
Unbeliever: Prove your claim that God exists. | Believer: Prove your claim that omniscience is logically unsustainable.
Believer: Prove it doesn't. | Unbeliever: Prove that omniscience IS logically sustainable.
Unbeliever: I've made no claim so the onus is on you | Believer: You've made the claim that omniscience as defined is to prove the claim you have made. | logically unsustainable so the onus is on you to prove the | claim since actual existence is irrelevant here.
I invite you to answer the question itself, and not keep trying to duck it.
Like I said...I've given a few propositions in answer. I don't "duck" questions. "Ducking" doesn't seem like a good path to a solution - if there is one.
If I don't know the answer or haven't a potential answer I will tell you and what's more I wouldn't look for one if I had thought you had proven your case.
Not only have I not ducked your question, I've given some answers in relation. I've also posed some questions which you yourself seem to have ducked, ignored, or not realized were asked. Perhaps you can reskim what I've posted and engage with what I've said specifically in regards to attempting to answer your question.
Humble regards...
