Another example.
But giving examples of math is no good Tarski. Math is completely conceptual. I appreciate it can be applied to the actual world. Negatives do exist in math. But when we are talking about things existing in the actual world, it's not just conceptual, if that thing exists. As I said before one can imagine an infinite (literally) number of things. To talk with any substance, as if a thing exists in the actual world, there has to be a link to the actual world. Where is Godel's link? As you said he could have used the term G-Like instead of God-like and I agree. At this point, I'm not even discussing that the def'n he gave either doesn't make sense or I'm not understanding the sense it's supposed to make. So please, if you are going to give examples don't use math. It's not the same thing.
previously:Why on earth for example would one ever present a definition of a thing actually existing without any justification or link to the actual world for that thing?
Tarski: Come on! How can one ask a question about something that has no definition?
If I ask you if you believe that infinite cardinals exist would you first want a definition? If I then give the definition would you accuse me of assume the existence of infinite ordinals in the first place? What a silly catch-22 I would be in.
I'm not following you Tarski. I didn't say one shouldn't give definitions, I said why would one do so, without any link to the actual world. And I'm talking about things which exist as actualities or potentially could exist as actualities. One doesn't first create def'ns of things existing and go looking for them, without any justification.
Let's say scientists expect to see intermediary stages of bone structure between one species and another, so if they go looking for them or have expectations of finding them...there is rational justification for doing so. Or let's say people have claimed to have seen giant octopus 40 feet long, and there were a number of sightings at different times, so scientists might go looking. Or a phenomenon is not explained well and something else is expected, because that explanation doesn't quite suffice, they might go looking, with an idea of what to find. But they can not go looking for every thing that man can possibly create by definition alone. It's a physicial impossibility. What link does Godel make to the actual world?
So when someone let's say a scientist sets up a definition of a thing and then gives that thing a label they are in effect presenting an assumption that that labeled thing exists.
How do you even come to the opinion that there is no God without having a definition to give when push comes to shove? Perhaps you mean sothing different than Godel or me or Mr. Tanaka. So if someone offers a definition of God for purposes of precision do you then accuse them of having assumed a priori that such a God exists?
No it is you that are working backwards.
First of all Tarski, no one would presume "no God" without first the notion of the positive "a God" The positive notion of something has to come first before any negative of non existence can logically be made. So to set up an argument which is about the existence of a thing and that thing is defined in Godel's case God ..that thing being defined is assumed to exist. That's what the argument is about.
As for you not being convinced I guess there is not much more I can say. Suppose I give you the standard proof that there exists an infinite number of primes and you say you are not convinced? I can try to explain but you are free to not be convince. At some point I should give up I guess.
You can have negative numbers, you can not have negative things. There is a Tarski..if Tarski was never born, there is no "negative Tarski". And if you weren't born there would be no reason for anyone to look for you.
All I can say more is that I have been working with definitions, axioms and theorems for more than 30 years and have published in top journals. This doesn't prove anything but it should give you pause.
I know it can be very frustrating.
I ran this by another friend (also an atheist and a logician). I asked if he thought that definition 1 simply assumes the existence of God.
He looked at me like I was kidding so I had to say, "just humor me". He said "Of course not. It's just a definition".
If I am presenting an argument to you about the existence of something and I say : x is pox-like if an only if it is red and slimy. Don't you think in that definition there is the assumption that a pox exists? It's possible it could exists as a conception only, but that's not what I'm attempting to present in my argument. I'm presenting you with an argument in which I am attempting to prove the existence of an actuality, something which really exists out there. By using ther words pox-like there is the implied assumption of a pox existing.
A deductive proof of the type we see here could never prove the existence of a material object of course. You seem to think Godel and anyone else must treat God as an (imaginary) material object. Godel does not view God in this way--Mormons basically do. Godel does you the service of defining what he means by his words to be clear, and you object that, by this kindness, he has already begged any and all questions about God. That's weird.
No I'm not assuming Godel's God has to be material. Frankly I don't know what Godel's god is, I've asked the question and didn't receive a response, from either CC or Gad. I had a few questions which I'd have to go back and find. Can you tell me what Godel's god is? But the use of the word God(-like) in the definition assumes that God (whatever it is) exists just like the use of the word pox (-like) which I used previously assumes a pox exists (whatever it is).

marg,
There are numerous techniques in fallacious arguments.
Tarski by accident or design employs a number of these. The topic originally “The Roles of Logic and Science in Questions of Theology” is not limited in the way
math. Theology is not about math.
1. Definitions are essential.
2. Clarity and precision of definitions are important if not essential.
No one has even attempted to refute that. Nor has anyone refuted the ambiguity which I cited in CC’s replication which is what we are all able to view without further research. If CC’s replication is incorrect/inaccurate, no one has made that claim. I raised that question in my comments to Tarski.
Developing any elaborate construction of argument with the use of
ambiguous terms devalues that argument.
(I recognize you could say that I’m making assertions, but I’m prepared to address challenge to them.)

The topic under consideration is not confined to
math. Your observation is important. While science is intimately connected with math, theology is not. And the question of the topic is essentially being ignored in all the illustrations from math.
Tarski did not address the issues which I raised except to repeat his position. I asked why not some
neutral reference to “x.” His response was to repeat his claim. By
adding further terms for which definition is required, Tarski is guilty of Fallacy: Muddy the waters as well as Shift the topic.
Both are Fallacies and further generate ambiguity. Rather than track my analysis point by point, he short-circuits by omitting the point by point detail which I provided.
Instead of addressing directly my analysis, he repeats his claim.

All Tarski quoted from my analysis was the following:
Response to Tarski Sat Sep 01, 2007 7:27 am
That post is far back from where this response appears.
1. What is the topic under discussion?
It is:
The Roles of Logic and Science in Questions of Theology
2. Following that title, we have discussion in which an ever-present term “God” in
Theology is used.
3. Assuming the quote from CC is accurate, the
fuzzy construction lies there.
That is where the explanation needs clarification.
Tarski stated:
You need to explain this better. How does merely making a technical
definition amount to assuming the outcome of the argument??
(JAK asked:)
What’s
your basis for concluding we have in definition 1 “merely making a technical
definition”? It is not stipulated on the page CC gave. If it’s stipulated elsewhere -- where? And we have at hand the topic
The Roles of Logic and Science in Questions of Theology.
-------------------
Following that (Fallacy by Reduction of Argument), Tarski state:
“He (Godel) is defining a term. That’s a coinage. We do it all the time in math and logic.”
Tarski is
Begging the question.
Tarski does not respond to the question:
What’s your basis for concluding we have in definition 1 “merely making a technical
definition"?
Let me point out that Tarski never responds to
his basis for
his claims. He repeats:
“He (Godel) is defining a term. That’s a coinage. We do it all the time in math and logic.”
The answer is
irrelevant to the question.
Tarski stated:
“I do not claim that Gödel’s proof is successful JAK. I do claim that Definition 1, despite being unclear by virtue of reference to an undefined notion of positive, nevertheless does not assume the existence of God.”
Still begging the question
Why did Gödel
do this? If it was Gödel’s intent to
focus on definition only for a deductive construction, why use a clearly universal term of
religion?
Tarski had given no satisfactory answer.
Having said that we should recognize that Tarski also stated:
“I do not claim that Gödel’s proof is successful JAK.”
As Tarski claims that: “You (JAK) are simply mistaken on this point,” he continues to beg the question as to
why Gödel would deliberately use a
loaded term “God-like” in his construction. It's Tarski's
claim that we have "merely ... a technical definition" and "just coinage."
It was not Tarski, but CC who
claimed that Gödel
proved the existence of “
God.” Now why would CC do that?
I think it’s fair to consider that because Gödel repeatedly refereed to “God” or “God-like” that someone (like CC for example) would leap to the erroneous conclusion that
Gödel proved that God exists.
The flaw and lack of clarity lies in the use of “God-like” rather than some
neutral (meaningless) term for purposes of a syllogistic construction.
Tarski failed to respond to the questions I raised regarding
why the use of “God-like.” Repeating his
claims was not a response to analysis.
marg,
See Christian History Institute
Read all of that page, but particularly scroll down to read the following:
“Godel's proof fits well with Christian beliefs about the universe, by analogy. Judeo-Christianity has long held that truth is above reason. Spiritual truth can be grasped only by the spirit. Had Godel been able to show that self-proof was possible, we would be in deep trouble. The universe might them be self-explanatory.
The implication of his proof is that the infinities and paradoxes of nature demand something higher, different in kind, more powerful, to explain them, just as every logic set needs a higher logic to prove and explain everything within it.
In other words, no finite system, even one as vast as the universe, can satisfy the questions it raises.
Godel recognized this and tried to find a watertight proof of God's existence. He failed. Sadly, the evidence of his life suggests he failed to find a personal relationship with Christ either.”
The bold is my addition to focus on quite possibly
why many Christians have a great affection for Godel.
So, Godel
was trying to find “a water tight proof of God’s existence.”
Whether Tarski knows of this information, I don’t know. But it is a partial answer to my question to Tarski:
Why did Godel use “God-like”?
All the
muddying of the water does not obfuscate if one really explores Godel’s choice of “God-like.”
Evidence in the weblink suggests that the word-choice was
not "merely" or just "coinage."
