I think there is a huge confusion about what free will means.
Agreed. What some call free will is what others call the illusion of free will, which as you described, is the feeling that one had a desire and was free to act on it when in fact perhaps he didn't have a choice. What I am interested in is whether that "choice" could have been otherwise, and I've decided that the question is unanswerable not just for now, but unanswerable in principle. What test would resolve that matter? Even if we had the power to go back in time and relive that moment with those same precise parameters of all of the contents of spacetime, we wouldn't answer the question any better than the last time we were at that point in time. We wouldn't be there the second time with a memory that we had been there once nor how we chose before.
I can't think of another means of resolving this issue, and that one doesn't work.
You don't control outcomes. That's a common misconception about what free will actually implies. What you have is a degree of freedom over which actions you take; the outcomes are always beyond your control.
Sure we do. That's the value of knowledge. We don't control all outcomes. We might not be able to stop the rain from falling, but we can be sure that the outcome is that we remain dry.
The omniscient God can and does know the future even though it is not predetermined.
That's the claim. Others find it incoherent, that is, internally self-contradictory. Skeptics don't accept the claim, but we can stipulate to the possibility and fact of perfect knowledge in a deity.
God has perfect foreknowledge, so everything that will ever happen to each and every person in their lives is written on the Tablet of Fate. Whatever we end up doing will be what God knew we would do, because God is all-knowing.
That's a statement of what omniscience is and a description of a deterministic world - one in which the future can in principle be predicted perfectly from a perfect knowledge of the present.
Humans have free will and the ability to choose what we will do throughout our lives, over the course of time.
That's the other claim. We don't know that that is the case. Skeptics of Abrahamic theology say the two claims are incompatible.
These events have not happened to us yet since we exist in linear time
Here's where you jump the shark. You've got the deity and man living in different realities. One can claim that deity experiences reality differently than man, but not that the rules of that reality are different. We experience time as a flow of consecutive instants in which the conscious content evolves from was to is as present instants become past instants and future instants manifest as the new now, but even if that's just a subjective perspective, it's being had withing a universe where the future is ordained even if that future isn't very clear to man at any given time.
But none of that makes the claim of the coexistence of free will and omniscience coherent. Simply saying that reality looks different to an omniscient god that can sense and experience dimensions and perspectives unavailable to us doesn't change what's logically possible.
I know what he is saying. But it's absurd.
No, what YOU are claiming is absurd. It is absurd to claim that the future is known but that man can freely make choices at the time of action that he could have made otherwise.
has not understood the OP and completely ignored it. Completely. You have too.
I refuted it and you ignored my refutation. Your argument's first point was to claim that "knowledge is not causation thus we do have free-will." That's a non sequitur. The words after "thus" don't derive from the words preceding it. You might as well have said Bob is six feet tall thus it's Monday.
The second part was the same kind of hyperdimensional sleight-of-hand that
@Trailblazer mentioned and I just addressed. There, you claimed, "God is a transcended being and he transcends time." That's a vague claim that translates that you want your deity to be excused from the rules of reason.
Answer the question directly without any other irrelevant rhetoric like earlier please.
This is a bad faith habit of yours. You assert control you don't have and aren't entitled to, and you are dismissive and condescending. In the past, you've eventually begun trolling your collocutors with a series of these brief, dismissive comments rather than engage in dialectic. You begin that way. You brought and presented an argument for discussion. But once everything has been said and said again, and you've made no progress, your tendency is to switch to this mode here. You don't get to call the other guy's response beating about the bush or irrelevant rhetoric. You need to make the evidenced argument.
