No, he’s not.
Yes, he is.
Denial is not just a river in Egypt.
“Pot, this is Kettle. Come in, Pot. You’re black, over.”
Wrong. Tyrion’s question is philosophical, not dogmatic. Tyrion freely admits and in fact insists he has no interest in dogma.
His question may be philosophical in tone, but it’s still nonsense. “What is the nature of God’s omniscience? But, leave all mention of the divine itself out of the answer!”

Complete, utter and stinking bullplop.
This is a philosophy forum and Tyrion’s question is entirely philosophical in scope.
To be philosophical implies that he has tried to use some sort of logic to arrive at his premise. I’ve seen better questions posed on the back of a Cheerio’s box.
 
Apologies for the delay in replying, my limited time on this forum has been taken up with another thread recently and in truth this one seems to be getting tied up in minutiae.
This follows from the law of non-contradiction, yes.
Great, we’ve done most of the hard work now. So just to be clear we have reached the following position.

<> = possibly.
] = necessarily.

E = there exists.
/\ = AND.
/ = OR.
~ = NOT.
w = possible world.
w(X) = possible world wherein X.

G = God.
T = Tyrion.
G(X) = God predicts X.
T(X) = Tyrion chooses X.

Love4All’s statements

(1) E w( (<>T(A) /\ <>T(B) ) /\ G(A) ).

“There exists a possible world wherein (Possibly, Tyrion chooses A, and possibly, Tyrion chooses B.) AND God has predicted A.”

(2) ~<>(T(B) /\ G(A) )
It is not possible for Tyrion to choose B AND God to have predicted A

So taking (1)

(1) E w( (<>T(A) /\ <>T(B) ) /\ G(A) ).

We can resolve this slightly as follows:

E w( (<>T(A) /\ <>G(A)) /\ (<>T(B) /\ <>G(A) ).
There exists a possible world wherein (possibly Tyrion chooses A and possibly God predicts A possibly Tyrion chooses B and possibly God predicts A)

E w( (<>(T(A) /\ G(A)) /\ (<>( T(B) /\ G(A)) ).
There exists a possible world wherein (possibly Tyrion chooses A and God predicted A and possibly Tyrion chooses B and God predicted A).

However you have already stated for any possible world w,
**~<>(T(B) /\ G(A) ) **
For any possible world it is NOT possible for Tyrion to choose B and God to have predicted A

Which contradicts that

So E w( (<>(T(A) /\ G(A)) /\ (**<>( T(B) /\ G(A)) **).
There exists a possible world wherein (it is possible that Tyrion chooses A and God predicted A and it is possible that Tyrion chooses B and God predicted A).

Hence there is a direct contradiction between the two positions. Both of which you were holding to be true.

I ONLY CARE ABOUT THE FULLY SECULAR CONCEPT OF OMNISCIENCE!!!
Clear enough? Do you understand “fully secular”? Before one can apply a concept to God (or anyone else!), it MUST be defined precisely.
generally speaking here:
God doesn’t mess with one’s mind,
it does so itself, the more and more into absurdity it drifts

in real life, “A” may most definitely be chosen with the person believing they have chosen “B”

being three persons God even transcends “personhood”
omniscience is not some law of physics, principle of the universe
it is what naturally, obviously belongs to the Creator of all that is, was and will be

This thread is great because we get to share our thoughts about God.

We do the best we can to understand Him, but our labels can only point in His direction; they cannot contain Him
As far as I am concerned it is not a matter of defining words such as omniscience more precisely.
The purpose is to get closer to Him, if that doesn’t happen, the meaning of such words as they apply to Him, will be no clearer.
 
This “paradox” only proves that Tyrion, as the main actor of the game, is so pathetic that he doesn’t even know how pathetic he is. To make up a setup in which indeed a man who plays it will “prove” that Tyrion will do any way what he wants and something different than those man’ words, then not only to imagine that god in the place of that man can do only the same, but to impose that god has to do only like a man (so there is no room for either omnipotence/omniscience in his actions), then to conclude that god is not omnipotent because you made such a “theoretical experiment where his omnipotence doesn’t show up”… then to pretend what a rational man an atheist can be because doesn’t believe there can be any omnipotent person ???

I will add, to avoid any misunderstandings, that at least I know how pathetic I am.

Full stop. No, we cannot. You have not resolved it, you have altered it. Your statement above is logically distinct from both my statements. You have committed an error of modal logic. Examine the difference between your statements above and the statements I have made, and with a little discipline, you should be able to discern your error. Or if not, then ask me to do it for you, and I will.

Thank you! You do grasp the essence of my demonstration. It is not God who “tricks” Tyrion, it is Tyrion who invites confusion upon himself, by his pride. God “hath confused the proud in their inmost thoughts.” It is not a “trick.” It is authentic confusion of mind, the humbling consequence of pride.

Well, it was you who presented the movie analogy (which I embraced, since I find it most appropriate).

So now, since the movie/play analogy argues against your interpretation, you wish to discard it? :tsktsk:
No, not at all! However, I did a poor job in elaborating what I meant by the ‘movie’ analogy. I even took the step of pointing out where the analogy falls short, though. So, you can’t beat me over the head with your take on the analogy and tell me that I’m abandoning ‘my analogy’! 😉
Let me make a short summary:
  1. theists assert that God “acts”, or makes “changes”.
  2. the metaphysical concept of action - which is independent of a temporal framework - involves a “change”. (Otherwise there would be no difference between action and inaction).
  3. Any kind of change means a temporal “before” and “after”. (Without a before and an after there cannot be a change.) So it is action and change which will necessitate the introduction of some kind of “time”. Without this time the whole idea of “change” and “action” would collapse, and this would contradict assumption #1 (God acts).
    It is this contradiction which makes the assumption of some temporal framework logically necessary for God.
Hmm… nope. Let’s review Thomistic philosophy:
God is the ‘unmoved mover’; that is, God is Pure Act. But, he’s not ‘act’ in the sense that something else actualizes him (e.g., there is some causal chain that we can walk backwards along, in order to find the cause for the action); rather, God is unactualized actualization. If there were change – before and after – to God, then our definition would no longer hold: there would have been some actualizing force ‘before’ that caused God’s actualization ‘after’. However, this cannot follow from the definition, so we have to either dump the definition or admit that we’ve improperly thought through this.

So, God is Pure Act. There cannot be any potency in God; this means that, necessarily, God is immutable – He himself does not change. (Now, mind you, he may cause other things to change – after all, he creates the universe, which is a change – but God himself does not change.) For some reason, you want to impute the change in the universe to God in his person; but that doesn’t follow. Therefore, by the very definition of what it means to be ‘God’, God is eternal and immutable. Therefore, God creates the universe eternally, even though, in its own context, the universe is temporal in nature. (This implies that the universe – which is compound in nature and not simple – undergoes change, and therefore, there is ‘before’ and ‘after’ (i.e., change) and a temporal framework in which this ‘before’ and ‘after’ exists.)

There is no contradiction here, as you have attempted to assert.
Unfortunately, many apologists take that “track”, whenever their argument collapses. Whatever the scenario, they start with an assertion about God, which takes the form of “God is/does something”.
God is Pure Act. You’ve already asserted this, yourself.
When their assertion is refuted, they try to salvage their position by a cop-out: “when it comes to God that something is fundamentally different from a human framework”.
Which makes sense: the human framework – or more accurately, the framework of the created world – is fundamentally different from God! If you assert that there isn’t a fundamental difference, then God is no longer an ‘unmoved mover’ – he is simply just another link in an infinite regress! Since this is impossible, you cannot assert that God is explainable in terms that apply to the universe without invalidating your entire argument. I appreciate that you don’t like this logic, and it frustrates you, and you might wish to ignore it, but it’s logically solid.
I did it in the paragraph above.
OK. Thanks!

You see, though, that your explanation can’t hold up. Either it’s lacks explicative force, or it contradicts the notion that God is God. You can’t have it both ways – you can’t posit God as God and yet refuse to accept what logically follows from that assertion. 😉
 
Continuing…
Is it meaningful that something can be known that does not exist and did not exist?
Since knowledge is information (which concept was not available to people in the past) it is blindingly obvious that one cannot gather information about something that does not exist.
Here’s the problem: in our frame of reference, things that appear as ‘future’ events “do not exist.” However, outside our frame of reference, where time is not a constraint, these things do exist. It’s not as if their existence is contingent upon our perception of their existence, from the perspective outside our spacetime framework! From our perspective, a book that is published next year exists only in potentiality (but upon publication, it exists in actuality); from the perspective outside our framework, this dependency does not exist! Oh, sure, when describing it, God might say “Gone with the Wind, Part II: Rhett in Rio exists in 2014”, in order to describe it with respect to the (internal) dimension of time in our world, but the point is that to God’s perspective, it exists. Period.
One can surmise, imagine, etc… but one cannot know.
This is a valid assertion – but only from within the constraints of our temporal framework. Outside that framework, your assertion doesn’t hold. If one is not constrained by time, then one knows. (Otherwise, if one holds that such knowledge is unknown, then what one is really saying is that the outside-the-framework observer isn’t really outside the framework: he is constrained by the temporal dimension of that framework! That, of course, is a contradiction – the assertion fails!)
This is the reason that I presented all those scenarios about the “book, which does not reside on my desk”. Since there is no book there, it has no title, and therefore it cannot be known.
No: it cannot be known by you, and at the present time. Unless you make those distinctions, you are not completely expressing the reality of the situation.
Now, let’s look at two problems.
  1. Is traveling into the past possible?
  2. Is knowledge of the future possible?
Again, you’re not fully describing the situation. Your questions are “can a person within the constraints of our space-time travel into the past?” and “can a person within the constraints of our space-time know the future?” Once you put those qualifiers on your statements, you can answer the questions.
  1. If traveling into the past would be possible, then the past COULD be changed, and this change could include the destruction of the present, which made time travel possible. The good-old grandfather paradox.
This presumes that ‘traveling into the past’ implies existence in the past as an actor. If ‘traveling into the past’ means something like ‘being an undetected observer who does not act’, then your consequence doesn’t follow. The paradox doesn’t necessarily follow from the premise.
  1. If knowledge of the future would be possible, then this knowledge could allow to take a different course of action, which would invalidate the “current” knowledge about the “future”. If I could know that taking route “X” to work would place me into a pile-up, and thus causing my death, I would not take route “X”, and therefore the predicted future would NOT come to pass.
There’s a whole boat load of assumptions there! At the very least, if you ‘knew the future’ in a way that allows you to change it, then that means that you didn’t, in fact, ‘know the future’ – you just knew of one possible future! Your thought experiment doesn’t lead to the conclusion you wish it to!
 
It took a long time before the theists realized that God’s assumed omnipotence does not need to include creating contradictions, so it will also take some while before they realize that God’s assumed omniscience does not need to include “knowing” the unknowable.
Whew! I’m so glad we theists have wise overlords like you, to condescend to us and pat us on the head and tell us what we’re going to eventually realize! Oh, thank you, wise and powerful Tyrion! :bowdown:
Maybe sometime there will be a good, solid - and yes! - secular definition of these concepts. Though I doubt it.
I agree with you, by the way. If your desire is to posit ‘omniscience’ within the constraints of our physical framework, then no, there’s no way to do this. At best, you’ll end up with the Hegelian concept of standing at the mountaintop: at the end of time, the sum total of all human experience will finally have the perspective to look back and see all that has happened within the framework of this created world. In doing so, this Geist will have access to all of history, and will – in that context – be ‘omniscient.’ In that context, ‘omniscience’ is simply a matter of knowing all of history. From a purely ‘secular’ standpoint, that’s as good as it gets. Sorry. 🤷

Now, if that’s what you want out of a definition of ‘omniscience’, then your thought experiement is worthless: it posits a ‘future time’ that doesn’t exist within the context of ‘secular omniscience.’ In other words, if you want an omniscient secular being, then by definition, he has no future! There is no time in the future in which he has the option of throwing or not throwing dice! 😉
 
:bowdown::bowdown::bowdown: How clever everyone is. And where does it get us?

Linus2nd.
 
The whole problem revolves around “what can be known”, or what does “omniscience” mean?
The problem can’t really be the definition of “omniscience.” Nobody here (that I have seen) has denied that omniscience includes God’s ability to foresee the future acts of all rational creatures with certainty. If any Catholic tried to deny that then they would directly contradict a de fide teaching of the Church as held by the First Vatican Council, session 3, ch. 1:
  1. Everything that God has brought into being he protects and governs by his providence, which reaches from one end of the earth to the other and orders all things well [11]. All things are open and laid bare to his eyes [12], even those which will be brought about by the free activity of creatures.
ewtn.com/library/councils/v1.htm#4

In any case, if your argument is that the future is unknowable, therefore God cannot know it - why didn’t you just assert it at the outset? The tortuous thought experiment you provided can in nowise lead to that conclusion. On its best day it could only show that if God provides Tyrion with information about his own future, Tyrion could change the future such that God is no longer omniscient. It could never prove that in all cases, or even any other case, the future is unknowable.
Obviously everything that “exists” can be known. Also obviously everything that “existed” can be known to someone who existed “back then”, when it happened.
Yes, and someone who hasn’t experienced past events can still know them. If we use justified-true-belief as the standard (ignoring Gettier and other problems), then we certainly can know past events without direct experience. It is either true or false that the lunar landing occurred. We have visual footage of the landing that is beyond reasonable dispute, giving justification. We believe that the moon landing occurred. We have knowledge that the landing occurred. If all you are asserting is that we have a higher degree of knowledge of the past through direct experience than otherwise, then I agree with you.
The problem is the future in particular, or the “nonexistence” in general. Is it meaningful that something can be known that does not exist and did not exist?
It isn’t uniformly held by philosophers that future propositions are unknowable. The truth component of knowledge becomes important ie. the correspondence theory. It shouldn’t present a problem to B-theorists if they hold that future events do exist as a four-dimensional block, because even under the correspondence theory there is a fact or reality that corresponds to the truth assertion.

Putting the B-theory aside for a moment, there is something that doesn’t quite fit with experience when you declare that the future is unknowable. All of the empiriometric sciences, to the extent they are useful, give us information used to calculate the probability of future events. And in most instances, they do it very well. If a materials engineer predicts that a stress test on a pillar of concrete with a certain tensile strength will destroy it (based upon thousands of prior tests with the same material), and the test conducted one second later does in fact destroy it, at what point did the engineer have knowledge of the outcome? Will gasoline still be combustible tomorrow? We certainly act like we know it will when we fill up the gas tank.

What seems “blindingly obvious” to you doesn’t to many other philosophers who have treated the subject. The bottom line though is that the thought experiment you offer doesn’t disprove God’s omniscience.
 
I believe God is smart enough to know that SAYING you will do something you don’t want to do will result in the opposite effect.

While a pagan and fictional example, recall the story of Oedipus. They were damned sure they weren’t going to have Oedipus kill his father and marry his mother, but it happened not only despite their best efforts, but because of them.

Your best efforts to defy his omnipotence will only result in failure because he knows you will try to prove His omnipotence isn’t omnipotent however you want. But He still knows exactly what you’re going to try to do.

And if He can describe what you are going to do immediately, can’t He also describe what you will do days, weeks, months, years, decades, centuries, and millenia into the future until the end of time (and beyond)? Why should He stop with right here and now? Of what consequence would that be to you? What would it accomplish for Him?
 
Full stop. No, we cannot. You have not resolved it, you have altered it. Your statement above is logically distinct from both my statements. You have committed an error of modal logic. Examine the difference between your statements above and the statements I have made, and with a little discipline, you should be able to discern your error. Or if not, then ask me to do it for you, and I will.
Hmmmm, I do not believe I have made an error here. If you believe otherwise then by all means please demonstrate.
 
Hmm… nope. Let’s review Thomistic philosophy:
Let’s don’t and say we did. 😉 (Just kidding!) But, for the record, I reject the thomistic philosophy, because it is incoherent. And also for the reason that it is NOT the official catholic philosophy. Also for the record, the catholic church has NO official philosophy.
God is the ‘unmoved mover’; that is, God is Pure Act. But, he’s not ‘act’ in the sense that something else actualizes him (e.g., there is some causal chain that we can walk backwards along, in order to find the cause for the action); rather, God is unactualized actualization.
Since we can say that God’s “causative” factor is “within” God, this presents no problem.
If there were change – before and after – to God, then our definition would no longer hold: there would have been some actualizing force ‘before’ that caused God’s actualization ‘after’. However, this cannot follow from the definition, so we have to either dump the definition or admit that we’ve improperly thought through this.
Definitely drop the incorrect definition. In my little list I made a metaphysical argument, not a physical one. If there is any meaning to “action” , there musty be a difference from “inaction”. If “action” means something, then there must be a “change”. If “change” means something, there must be a “before and after”. There is noting here that would require a “temporal” framework.
So, God is Pure Act. There cannot be any potency in God; this means that, necessarily, God is immutable – He himself does not change. (Now, mind you, he may cause other things to change – after all, he creates the universe, which is a change – but God himself does not change.)
This is the moment where your argument becomes problematic. (Not you "personal fault, of course.) You use the words “…cause other things to change”. Now, regardless of the specifics of the “causation”, there is an “action” there. The first sentence of Genesis is: “God said: ‘Let there be light’…”. It does not matter, if there were actual “words” or just an internal “will”, there is something that happens. And “happens” drags along “change”… etc. Mind you, it is not required nor asserted that God’s “essence” would change. (Whatever that “essence” might be.) Just like your essence does not change when you make a decision to create an answer to this post.
Therefore, God creates the universe eternally…
This phrase is meaningless. And there is a confusion between “action” and “inaction”. Yes, I heard it before. God “eternally wills” X. It has no informational value. Besides, the word “wills” implies an action.
Which makes sense: the human framework – or more accurately, the framework of the created world – is fundamentally different from God! If you assert that there isn’t a fundamental difference, then God is no longer an ‘unmoved mover’ – he is simply just another link in an infinite regress!
Not so. The first decision does not have to be “external”.
You see, though, that your explanation can’t hold up. Either it’s lacks explicative force, or it contradicts the notion that God is God. You can’t have it both ways – you can’t posit God as God and yet refuse to accept what logically follows from that assertion. 😉
I say that the presented “concept of God” is incoherent. In the presented picture there is no difference between “action” and “inaction”, between “change” and “no change”, between “before” and “during” and “after”. So what you presented here has no informational value. It is just a string of characters without any meaning, just like the phrase of “that which exists to the north from the North Pole”. And all this just to preserve the idea that God can know what does not exist. It ain’t worth it.

On one hand you argue that you are in the position of speaking “authoritatively” about “timeless” existence, and its “internal workings” (eternally wills!), you use words like “causation”, “action”, but when I point out the problems with your assertions, you say that these words mean something totally different, thereby undercutting your whole argument. You say that my arguments are fine in a temporal framework, but they are inapplicable to the “non-temporal” one. So we are unable to find a “common language”. In a sense you say that one cannot say anything meaningful about the “timeless” existence (starting from a temporal frame), and then you turn around and try to say something (also starting from a temporal frame - like “eternally willed”), and you are surprised when such undefined nonsense is rejected. There is a philosophical term for what you committed here. It is called the “fallacy of the stolen concept”.

Buy the way, I use “you” in the general sense, not “you, personally”. After all you did not invent all this. 🙂

To be continued sometime later…
 
Love4All’s statements

(1) E w( (<>T(A) /\ <>T(B) ) /\ G(A) ).

“There exists a possible world wherein (Possibly, Tyrion chooses A, and possibly, Tyrion chooses B.) AND God has predicted A.”

(2) ~<>(T(B) /\ G(A) )
It is not possible for Tyrion to choose B AND God to have predicted A

So taking (1)

(1) E w( (<>T(A) /\ <>T(B) ) /\ G(A) ).

We can resolve this slightly as follows:

E w( (<>T(A) /\ <>G(A)) /\ (<>T(B) /\ <>G(A) ).
There exists a possible world wherein (possibly Tyrion chooses A and possibly God predicts A possibly Tyrion chooses B and possibly God predicts A)

E w( (<>(T(A) /\ G(A)) /\ (<>( T(B) /\ G(A)) ).
There exists a possible world wherein (possibly Tyrion chooses A and God predicted A and possibly Tyrion chooses B and God predicted A).
My apologies, I misspoke previously. Upon further examination I can see that it is not in the previous line that your error lies, but rather here. The previous line is actually a legitimate application of the law of distributivity. This, however, is not. This, is rather, an error in modal logic. The <> operator is not distributive as such, thus it is an illegal transformation, to go from (<>X /\ <>Y) to <>(X /\ Y).

A little examination of the above two expressions reveals them to be incompatible if we consider what would happen if, as is actually the case in our hypothetical, X and Y were mutually exclusive options. The first expression, plainly, entails no contradiction to that idea whereas the second, plainly does, and therefore is the illegality of the transformation you have used made manifest.
However you have already stated for any possible world w,
**~<>(T(B) /\ G(A) ) **
For any possible world it is NOT possible for Tyrion to choose B and God to have predicted A

Which contradicts that

So E w( (<>(T(A) /\ G(A)) /\ (**<>( T(B) /\ G(A)) **).
There exists a possible world wherein (it is possible that Tyrion chooses A and God predicted A and it is possible that Tyrion chooses B and God predicted A).

Hence there is a direct contradiction between the two positions. Both of which you were holding to be true.
Possibly, Tyrion will choose B, and possibly, God will predict A. The conjunction of two true statements is true, so the expression

<>T(B) /\ <>G(A)

is true. But it does not imply, and cannot legitimately transform to, that it is possible that Tyrion will choose B AND God will predict A.

~<>(T(B) /\ G(A)).

There is no contradiction in anything I’ve said, but there was an error in your modal logic.
 
Ok, let’s continue.
Here’s the problem: in our frame of reference, things that appear as ‘future’ events “do not exist.” However, outside our frame of reference, where time is not a constraint, these things do exist.
Where? When? How? The ontological objects we speak of (books, for example) all have spatial and temporal coordinates. Where does that book “exist”, which has no even conceived yet, since the future author’s parents have not even met? What does the word “exists” mean for this book? You commit again the fallacy of the stolen concept, when you attempt to speak of “existence” for such a book. To speak of “existence” in this context is totally meaningless.
It’s not as if their existence is contingent upon our perception of their existence, from the perspective outside our spacetime framework! From our perspective, a book that is published next year exists only in potentiality (but upon publication, it exists in actuality); from the perspective outside our framework, this dependency does not exist! Oh, sure, when describing it, God might say “Gone with the Wind, Part II: Rhett in Rio exists in 2014”, in order to describe it with respect to the (internal) dimension of time in our world, but the point is that to God’s perspective, it exists. Period.
Existence is not conditional. You see, the problems do not stop here. It is perfectly possible that the “hypothetical book” will never be written. It will always stay an unfulfilled potential. But the assertion that God “knows” all the potentials, and as such you must assert that God “knows” the contents (etc…) of that book, which was never written and will never be written either. And that truly makes the word “knows” meaningless.

Furthermore, what you say is contradicted by the bible, and the catechism, and the dogmas. In the bible God is depicted as a very active person, who mingles among humans, who speaks and acts. Not to mention Jesus, of course. Also the dogmas and the catechism say (supposedly in an inerrant fashion) that God actively participates in every event, that God actively maintains the world. God is supposed to be not just a “first cause”, but also a “maintaining force”. And since the world is constantly changing, and God’s active action is required to maintain the changing world, therefore God is not and cannot be “unchanging”. Again, simple logic. Maybe you are tempted to say that all this is just our “imagination”, that we simply “perceive” the world as such, but I would not advise this approach.

God is also supposed to perform miracles once-in-a-while. They are God’s open interference into the state of affairs. Everything the church teaches points to an active and changing God. And yet the thomistic philosophy tries to teach something completely different. But since the thomistic philosophy is not “officially” accepted by the church, there is no reason for you, the believers to subscribe to it. And I will certainly reject it, as a logical and metaphysical nonsense.

I have seen the final “rebuttal” to this line of thought. The final “cop-out” is that all these are simply a mystery. Naturally, this is the cheapest excuse. When the theist presents a contradiction, and it is pointed out, then he simply pulls out the “get-out-of-jail-free” card, and says: “oh, that is a mystery”!!! To which I cannot answer with the proper phrase, since it is not allowed, and as such all I can say, it is stinking bovine excrement.
This presumes that ‘traveling into the past’ implies existence in the past as an actor. If ‘traveling into the past’ means something like ‘being an undetected observer who does not act’, then your consequence doesn’t follow. The paradox doesn’t necessarily follow from the premise.

There’s a whole boat load of assumptions there! At the very least, if you ‘knew the future’ in a way that allows you to change it, then that means that you didn’t, in fact, ‘know the future’ – you just knew of one possible future! Your thought experiment doesn’t lead to the conclusion you wish it to!
That is the point! Knowledge of the future and interfering with the past lead to a logical contradiction.
 
Tyrion may of course argue with Catholic Theology and call it contradictory as here, " ,That is the point! Knowledge of the future and interfering with the past lead to a logical contradiction,"

But that will not change the facts of the case. The Catholic Church teaches definitively that God is Omniscient, Omnipotent, Omnipresent, One, Unchanging and Unchangeable, etc. In the present argument that means that God knows all our possible acts and decisions before they acutally happen and has Planned for them before they happen. This takes place in His eternal Now but is worked out in our time limited universe. Thus, God does not change.

And while it is true that the Catholic Church has no defined Philosophy, it treasures that of St. Thomas highly and St. Thomas supports the teaching of the Church on the Unchangeableness of God. The teaching of the Church however is not based on this philosophy or on any philosophy, it is based on Holy Scripture and the Tradition and constant teaching of the Magisterium.

So the argument boils down to a matter of Faith. Catholics make no apologies for that at all. We have however pointed out the reasonableness of that Faith. Tyrion rejects that. So we are at an impass. Those whom the Spirit touches will make the right choice.

Well said. Time to shake the dust out of the ol’ sandals, and move on.
 
That is the point! Knowledge of the future and interfering with the past lead to a logical contradiction.
No one has introduced the idea of interfering with the past, which is absurd and impossible.

There is no contradiction between the following two future events in our hypothetical universe:
  1. at t[sub]0[/sub], God informs Tyrion of his future choice.
  2. at t[sub]1[/sub], Tyrion freely makes the choice in exact accordance with God’s prediction.
It is not a “mystery.” This is not faith. This is philosophy.

Those appealing to “mystery” and “faith” are committing the error of Fideism.

Those contending that the two statements above are as impossible as changing the past are committing some other philosophical error.

Depsite the weariness of some, this issue is not yet clearly grasped by all here. Those too weary to continue are free to stop replying, but there is nothing wrong with those who are given greater endurance to continue, and it is wrong to discourage those who still see some hope, however dim and bleak the future might look to those who do not share that hope.

I hold that my solution as presented earlier in this thread is definitive, but apparently, it has not been grasped by all, and it seems Tyrion has not yet even seen it.

But my point here is this: logic is logic, and sophistry is sophistry, and truth is truth. The charge that Tyrion is engaging in sophistry is either true or not true, there is no middle ground. If true, then it can be shown by logic. If it can’t be shown by logic, then it isn’t true.

IF Tyrion’s error cannot be clearly exposed by logic, THEN it is not the case that God can be known with certainty by the light of reason.

If my bolded statement in the above sentence is true, then Catholic Dogma is wrong, and anyone who wishes to be a Fideist has a lot more trouble on their hands than they bargained for. If on the other hand, the bolded statement is false, then someone ought to be able to show Tyrion in a way that he can understand.
