Quote:If somthing is logical it cannot by definition be incorrect or it is illogical
Not true. Logic does not necessarily equate with truth. It just a means of searching for truth. Its not an absolute.
log·i·cal ( P ) Pronunciation Key (lj-kl)
adj.
1. Of, relating to, in accordance with, or of the nature of logic.
2. Based on earlier or otherwise known statements, events, or conditions; reasonable: Rain was a logical expectation, given the time of year.
3. Reasoning or capable of reasoning in a clear and consistent manner.
The use of logic can be incorrect, but a logical statement becomes illogical when it is contradicted. Thus, for a statement to be logical it must hold no contradictions, in which case it is true.
So, you could have reasoned using logic:
The sky appears blue
my pants appear blue
therefore my pants have the same material as the sky
but form an illogical statement.
It only becomes logical when it is correct:
The sky appears blue
My pants appear blue
light wave patterns affect color perception
Therefore the light must be effecting my color perception in a similar way on blue objects.
That statement is logical, unless it is proven wrong, making it illogical.

Close. But not quite true. Logic needs evidence at its starting point. The subsequent steps in a logical process do not need physical evidence. They can run on pure reasoning. That is what defines logic.
But i do agree with you that the bible is circular. It is POOR evidence for the existence of a God. I admitted that before. Unfortunately POOR evidence is still a piece of evidence...whether we like it or not.

Yes, not all of the steps need observation. But you need to start with observation (evidence).
It's widely acknowledged by both dualists and materialists that the bible is a circluar argument. However, to defend the bible, dualists say that circular arguments are valid sumbission of evidence (which they aren't, they only speak of the nature of the understanding.
