It is quite simple really. If an intelligent agent is convinced that X will inexorably lead to Y, and that agent causes X, then that agent also causes Y. Causation is a transitive operator. (BTW, I have just showed the "hence" that you keep claiming that I have yet to show.)
It's not a red herring. If those propositions have no truth value, God doesn't know what will happen, so his creating the initial conditions PLUS his knowledge can't entail what you say it does...
You are wrong to merely assume that claims about the future have no truth value, especially since people generally assign truth values to claims about the future. You are confusing the property of having a truth value with one's ability to establish precisely what the truth value is.
You can't shunt this aside by saying "omnisicence has always meant this or that." What I'm trying to do is show you that you are (perhaps) making a mistake about what omnisicence means...
Word meanings do not exist independently of conventional usage. There is a long history of discussion about predestination in Abrahamic cultures precisely because God, as an "omniscient" being, cannot be ignorant of future events. You want to change the meaning of "omniscient" by claiming that the conventional idea of God is wrong--that omniscience is impossible as defined by most people in this ancient debate. I am not mistaken about what omniscience means, and I am quite happy to agree with you that there are no omniscient beings in that sense. But that wasn't the sense that the OP was addressing. You have turned the argument into a dispute about word meaning rather than about the substantive issue.
I take it to mean knowing everything it's possible to know. Or perhaps more modestly, knowing everything about the world. It's an open question whether future events constitutes something possible to know or something about the world. I'm still waiting for your analysis of truth such that future events are possible to know (i.e., such propositions have truth conditions) or that future events are relevantly "part of the world". Apparently I'll wait in vain. Fair enough, I suppose, if you choose not to deal with the issue.
You do understand that our perception of time is relative to our senses, don't you? Time does not progress at the same pace for all observers, and it is theoretically possible to engage in time travel. From the viewpoint of physics, time is not unidirectional. I see no reason why the Christian God would need to be limited to perceiving time at the same pace and in the same way that we are. After all, he is supposed to have supernatural powers, isn't he? It is not beyond the imagination of humans that even limited human beings can have precognitive powers. I'm quite willing to agree with you that the Christian God is extremely implausible, if not impossible. You are looking for some way to make some version of God more plausible by limiting what we conventionally understand omniscience to entail. Have at it. Just don't go trying to sell us the idea that this is the God that Christians believe in and pray to.
Chalk it up to stupidity, but I'm underwhelmed by the force of this argument. God creates condition set A. Exactly nothing follows from that even if God knows what the future will be (on the assumption that my argument about future-oriented propositions is wrong). For God's knowledge is based on what we do, not the other way around.
God creates the universe, but he has no idea how it will turn out until it does. God is immanent in a universe where the perception of time is relative to observers, and he is limited to the perspective of human observers. That seems to be the position you are trying to defend when you claim to believe the "argument about future propositions", which you explicitly denied believing in in an earlier post. So maybe God is really good at guessing? On what basis would he make such guesses? Knowledge of deterministic causality? Magical powers? Still, he conveys accurate, confident information about future events to assorted prophets. Is this making any sense to you? Not to me.
How many times do I have to say this? You have to show the "hence", and so far, you haven't done so.
You never had to repeat it in the first place, since I have showed the "hence". Causation is a transitive operation. A creator being who knows the consequences of his actions determines the events that are consequences of its actions. But keep on repeating the question, even after it has been answered. That rhetorical technique is called argumentum ad nauseam.
