Clarifying terms
and why an axiom is not Truth or fact
An axiom is something that is, for the sake of moving forward, assumed to be true (or a fact). That doesn't make it any more or less true than any other guess.
If using this as a basis for logical argument we arrive at things which can be checked it does give some support for the idea that we choose our axiom well.
The most famous case is the parallel lines axiom of Euclidean geometry. It certainly appeared to be true and is a very useful axiom. However, it is not always true it is just useful to take it as axiomatically true some of the time.
This is an example of using an axiom that is known to be not generally true but still useful.
What has to be done to ascertain the truth of any assumptions is to see if they logically lead to truths about the real world. That is what science does.
In your post 117 Message 117 you say:
DB writes:
and even testable from the application and correspondece to pysical things.
This is exactly where you stop using logic because logic by itself can not tell you what is right about the real world.
DB writes:
Even if you view Logic as mathmatics or by some other definition it has the capacity to develope a conclusion that correspondes to the physical world, when its conclusions are verifiable, knowable and sometimes incontravertable, even without the application of an actual physical test.
Somewhere you HAVE to have a physical test. Otherwise you arrive at conclusions using logic applied to your axioms which are logically sound but you have no way of knowing if you chose your axioms well.
Please explain how you would do without the physical test since you have them explicitly stated and implied all through post 117.

Slowly sorting out msg 117
I think that your position is completely put forth in Message 117 correct?
However, I have trouble reading it because it has two many words so I would like to slowly make it smaller and clearer.
Your first bit is what you label "Premise 1":
The proposition set out and explained.
Premise 1. Logic as a science to develope or enchance the idea of Creation or ID is demostratable from the fact, that one can establish Facts, ACTUAL facts, that are usable, knowable "understanding gained by experience"., (by any common definiton) and even testable from the application and correspondece to pysical things. One cannot simply dismiss the reality or value of a fact, because it is not established by the method of testing know as 'Natural science'. It can and has been demonstrated that truths in fact, also known as Axioms (self-evident truths) can be demonstrated as knowable and incontravertable by the premises they establish. It is agreed that even if you list Logic as only a Formal science, it still has the ability to establish actual facts in truth, the conclusions again, of which are incontravertable, Axiom
Again, bear with me please. Again there has been no possible alternatives offered for example in the Spock argument. The last attempt, was to say, "They are willing and able but have not decided to yet". Again, this only restates his proposition in another form and even if they had not decided yet to respond, it would still fall under the category of UNWIILING. Spock set forth an argument the conclusion of which was Factual that corresponded to the physical world but was not an actual test by the process of physical things. Whats the point.
You can have actual Facts that are real that do not need the actual testing measures set forth in the 'Natural science' definition. An Axiom. Simply stating that these are not actual Facts because they are based on Math or whatever, does not invalidate them as Facts. Its only that your definition of Fact will not allow this possibility. Further, the most important fact that establishes his argument and conclusion as Valid and Truthful in reality was that it was INCONTRAVERTABLE. It must be demonstrated to be incomplete and not axiomatic by refutation. Enough said on that illustration I hope.
Im getting to the application, but these are points that need to be established prior to that conclusion. Definitions and conclusions about what certain words are an actually mean are at the heart of the issue. You certainly can have almost no agreement if this is not accomplished.
The dictionary defines the word Fact as, "something that exists or is real". In other words it has the property as something that is knowable and identifiable, regardless of the type of test you apply to it. Even if you view Logic as mathmatics or by some other definition it has the capacity to develope a conclusion that correspondes to the physical world, when its conclusions are verifiable, knowable and sometimes incontravertable, even without the application of an actual physical test. In other words you can ascertain or grasp, that, "something that exists or is real" (Fact),by simply the application of the Science of Logic.
You seem to be saying here that logic alone can establish "facts". Correct? That seems to be the only thing you are trying to establish with this whole section.
You then say that these conclusions can be "usable, knowable 'understanding gained by experience',... testable. I understand this to mean testing the conclusion against reality (experience) and that they will be confirmed by this. Correct?
(This is by the way, natural science, that is various ways are used to arrive at tentative conclusion (including logic) and then they are tested against reality.)
It seems to me that the only difference between your premise 1 and natural science is that you say that the testing part is not necessary. Correct?
Now would you agree with these statements about logic:
1) The conclusion can only be valid if it flows with correct logic from the premises. (This is using valid as Chiroptera has taught me to. i.e., correctly tied to the premises but not for sure right)
2) A conclusion can be valid but wrong if the premises are wrong.

Re: Slowly sorting out msg 117
No I did not say the only way to establish facts is from logic, only that it is another possible way through the application of an axiom that correspondes to the physical world., ie the only three possible explanations of things in existence.

I guess I worded that poorly. I did not mean to imply that you said that only logic can establish facts but rather I wanted to say that you are saying that logic alone, that is, by itself (just logic) can establish facts. Correct? You seem to agree with that but I just want to be sure.
True the test is that it has to have application to the physical world. And all axioms (true axioms) of course apply to the real world. You will remember that I said axioms require no PROOF, or in this case , no further testing. They are usable , knowable and testable because they can be observed as applicable from the premise (physical properties) they speak about., Ie 'DEAD MEN TELL NO TALES". Can you test this axiom, yes?. Do you need to handle anything to know this, No. I also agree with you that what I am describing is the Natural science of testing and observation. Its just that the axiom, is step aoutside you methods, that is valid as well.
Then I still find this very confusing. The problem is, I think, I still don't know what you mean by "axiom". Others have pointed out (over and over) that the general meaning of the word is "some statment taken as being true without further examination". The key word is "taken". They are NOT automatically true they are just assumed to be to see what works out by using further reasoning. So that is one meaning of the word. If you don't like that definition we can call those assumed-for-now-axioms and not the kind of axioms that you are talking about.
You seem to be saying that axioms are something which is just plain true, period! That is they are "facts". Correct? But then you say "true axioms" which implies that some might be false. Can you explain?
But you seem to be wanting to use logic on them. Why? If they are 'true' then what do you can with logic?

Definitions of axioms
Ok I did not ASSERT that an axiom is true , factual and demonstratable, in and of itself. The definition of an axiom and the dictionary did it for me. If an axiom is not what it says it is then what is it?. Again I have demonstrated and proved the validity of these propositions numerous times. D Bertot.
Well, on this you are just plain wrong as far as the common definition and use of the word is concerned as I point out above.
So now we know that you and some of the rest of us are not talking about the same concept when we use the word "axiom". That means that it does us no good to continue to use it or discuss it with just that word. So let's have a couple of new words to sort out what we are saying:
1) assumed-axiom. - the way most of us use the word. It is something that is an assumed (for now ) to be true for the sake of further logical argument or discussion.
and
2) true-axiom. - a "self-evident" statment which is not just assumed to be true but actually is. This is your version of the word.
From now on no one is allowed to use axiom by itself. It is either an A-axiom or a T-axiom. Ok?
Now what exactly are you T-axioms from post 117?

Definitions
Crash, it is clear that we and DB are using different meanings for the word. It is also clear that DB is not going to change on this. So why bother? The exact word doesn't matter.
I have suggested A-axioms and T-axioms above. How about we all use those and carry on discussing Dawn's T-axioms now?

Summarizing it.
For this reason it is simply a contemplation or hypothesis not a true AXIOM.
And this does, indeed, summarize the whole thread.
The Fifth is THE classic example of an axiom. The use of axioms in Euclid's geometry is the classic use of them. Heck it is probably why we use the word axiom (which sure looks Greek to me).
That you can make the above statement shows how far off in your own little world you are.
