And, BTW, note that Aristotle's argument (when converted to a 20th century argument about "truth values") actually abstracts away from the semantics of the sentence. A statement about the future becomes a "tenseless" proposition, which is then examined outside the context of a speech act. Approached in that fashion, one invalidates the presuppositional context (what Austin referred to as "felicity conditions"). Claims based on false or invalid presuppositions do lack truth value. The philosophical problem, not surprisingly, seems to have arisen from a fundamental misanalysis of natural language.
I must admit, I have absolutely no concept of what you are talking about here.
A tenseless proposition? I won't make you explain it, unless you want to. Suffice it to say, I understood the article enough to see why it is problematic to claim that future propositions do not have a truth-value.
My one question was that you said a false presupposition lacks a truth-value. Perhaps I misunderstood what a truth-value is, but I was under the impression that a truth-value was simply the assignation of "true" or "false". So, then, "false" would be the proposition's truth-value.
Yes, this is a well-known philosophical position in free-will debates that is called
compatibilism. That is, in fact, my own position and that of a great many modern philosophers (e.g. Daniel Dennett).
For those who might not have read the third proposal in the article, I'll reproduce it here:
Norman Swartz said:
The truth of propositions does not 'make' events happen (occur).
Consider: My wearing a short-sleeved shirt today [Oct. 28] is what makes (the proposition expressed by) "Swartz is wearing a short-sleeved shirt on Oct. 28, 1997" true. It is not the other way round. Logical fatalism confuses the semantic (truth-making) order. It makes it appear that the truth of a proposition 'causes' an event to occur. It is, rather, that the event's occurring tomorrow 'makes' (but does not cause) the proposition to be true today. This is not 'backwards causation': the relation between an event and the truth of the proposition describing that event is not a causal relation whatever. It is a semantic relation.

I personally think that Proposal Three is the best (and dare I say?, the correct) reply to the problem of Logical Determinism. Logical Determinism may appear to pose a threat to the existence of free will, but that is only because it misrepresents the nature of the relation between a true proposition and the state-of-affairs in the world that accounts for that proposition's being true. It is the way the world was, is, and will be that account for propositions being true. It is not the other way round.
If you accept this proposal, then why do you also hold the position that God's omniscience denies humans free-will? It seems that this is the traditional defense of theists: Knowledge of an event does not cause the event to occur. Thus, humans can have free-will, even though God already knows what they will do.
Compatibilism asserts that determism and free-will are compatible. This is so, compatibilists claim, because nothing can be uncaused, but causes themselves do not deny free-will: ie, I choose chocolate icecream, because I desired chocolate icecream. My desire caused my choice, but because my choice was based upon my own desire, then it is free-will. Free-will is only compromised when another agent forces you to make a specific choice (ie, someone will shoot me if I didn't choose chocolate icecream.)
I do not see a clear parallel between Proposal 3 and Compatibilism. (Yes, they both claim that free-will and knowledge of the future can be compatible, but they appear to solve it in two different ways.) Could you clarify?
Additionally, if you accept compatiblism, I again do not see why this would change in the presence of an omniscient God... even if he were the Creator.
