We've been through all this before and given those premises it is the only logical conclusion. I think we arrived at the conlusion that no free will meant you are a machine and would arrive at pre-determined conclusions. If you called them logical that would in no way inform us as to whether the conclusion was logical or not. You would say what you had to say as a machine. And thats all. You never escaped from the circle of pointing to yourself as a freely concluding machine who couldn't freely conclude anything. IIRC

Yes agreed. That pretty much defines no free will.

Except that I was never in that circle since I never claimed to be freely concluding in any way shape or form. You just couldn't seem to accept that what I was saying is exactly what you have defined above.As a machine I have no choice but to do what I do. however as I have no pre-knowledge of what I will do, I have the illusion that it is otherwise.

So when you say 'logical conclusion' we have no reason at all to believe you.

Good point. I missed that in your definition.I guess that in the complete absence of free will then logic is really meaningless too since all we would be doing is following a set program of unchangable events. In the absense of logic as a valid concept you would have no reason to believe anything. Edited by PurpleYouko, : Corrected spelling mistakes

As usual you jump to the wrong conclusion.The whole point is that you can't tell the difference. unless you can show me a method to test for free will this is simply an exercise in (possibly illusionary, if no free will) logic. Just because in the context of exploring a logical outcome of certain fixed premises, you reach a point which seems to make no sense or is contradictory in some way is no reason to abandon the course of the logic. There are plenty of logical paths that lead to dead ends when based on fixed criteria. All it means is that you need to re-examine the premises and try again with slightly different starting data.

sorry
i meant by my stated questions that you could have free will and god exsist at the same time .... as you defining god does have a problem with the exsistance of free will ... this that statement that as god is all powerful and has no limits he can grant you free will , while still retaining his unlimited powers and vision .

No problems.
The point is that this is a thread specifically about applying formal logic and following it through to it's conclusions as opposed to applying "common sense" (or informal logic) When the premises are clearly defined, it is possible to follow a course of logical deduction in a formal way and by doing so, only one possible answer can be reached.
this that statement that as god is all powerful and has no limits he can grant you free will , while still retaining his unlimited powers and vision .
You are free to believe this if you like but the statement does not follow formal logic as it can be shown to be logically inconsistant.The train of formal logic says that if it is possible for any being or artifact to know ALL time infallibly then that time cannot be changed from the course it is already known to take. Therefore no free will. This is not an implied weakness of God but simply a statement of the nature of the Universe. Any Universe in which foreknowledge is possible has to follow a fixed path throgh time as any deviation from that path would render the foreknowledge incorrect. Logically, in order for God to grant us free will he would have to create a Universe in which the future is in genuine flux. (I'm sure that would be well within his power.) But by doing so he must make it impossible for the future to be known by anyone, including himself.

Except of course, you are predermined to accept the instructions known that have been predetermined justified as logic.

On the contrary, part of the pre-determined belief is the belief in free will.

Quite possible, assuming that the person performing the logical deduction is actually inside the system. As we are only performing an exercise in logic, it could well be assumed that the person performing the logic could be entirely outside of the given system. Let's say that person is God for example. Then again, if the premises are wrong then we have no problem. Our free will is genuine so our logic is no longer pre-determined.

Off Topic - DO NOT RESPONDi understand logic constrants , but can your logic cope with the idea of a god who caan step back a see the whole of time as one picture , a single frame so to speak , thus he can see you at time = 1 thinking about option a or b , he can see you at time = 10 making a free will choice between a and b and he can see you at time =100 experiencing the effects of the choice . from gods point of view all three time points are similtanious there is no past present or future but a view of everything , god see the whole universe including all time points of said universe .
The train of formal logic says that if it is possible for any being or artifact to know ALL time infallibly then that time cannot be changed from the course it is already known to take. Therefore no free will. does this logic not also mean god has no free will , as god cannot change time as he has effects on things subject to time , then god is part of the time flow .?? can you use formal logic to show an possible expersion of free will , that thus shows the future is not fixed ??

Off Topic - DO NOT RESPONDthus he can see you at time = 1 thinking about option a or b ,
This is the entire crux of the argument that invalidates free will.he can see you at time = 10 making a free will choice between a and b and he can see you at time =100 experiencing the effects of the choice . The point is that God CAN look at all time. He is able to see the very first insant of time and the very last instant and all instants in between. To use your example, He sees me at time = 10 making a "free" choice then at time = 100 experiencing the effects of that "free" choice. Then how about he looks at time 10 again, and again and again. Am I ever going to make a different choice? It's a bit like watching the replay of the Englan Vs Portugal World cup match. No matter how many times I watch it, Portugal are still going to win on penalties. To somebody outside of time, watching all time simultaneously, who also KNOWS every choice we are ever going to make, it is like watching a giant still shot with everything fixed in place. Every instant in time is fixed. from gods point of view all three time points are similtanious there is no past present or future but a view of everything , god see the whole universe including all time points of said universe .
Exactly so how can it be anything other that what it IS? Free choice implies that it is changable.
does this logic not also mean god has no free will
not at all since God created time and remains outside it. The logic implies that TIME is fixed, not God. he can recreate it to be different whenever he wants to.
can you use formal logic to show an possible expersion of free will , that thus shows the future is not fixed ??
I cannot see any way to show any kind of logical consistency between it being possible for God or anybody else to know all time, and the existence of free will.To know it, it must be fixed. If it can change unpredictably (ie. by a free choice) then it isn't knowable. Edited by AdminNWR, : off topic

Caution. Please recheck the OP. This is not a topic about free will.

sorry did not mean to stay off topic , i was trying to see how and if the use of formal logic could apply to things that do not seem commanly logical . i was using free will as a test subject to have the disipline of logic applied to it . clear needs a different topic . again sorry .
