Indeed, there is more than one sense of the word "valid" or "logic." So also with other words, like "love," agreed? But when I am talking about my wife and I say "I love my wife" it is easily understood as the sense of commitment, romance, etc, etc. If I say "I love steak" it can only be properly understood in the sense of the pleasure of tasting and satisfying my hunger. I wouldn't say "I love steak" and expect someone to understand that I meant I took vows at the altar with a sirloin.
This is because using language properly involves knowing what words to use in the context of conversation, discussion, debate, etc. Forgive me for being blunt, but you should have learned this at a very young age JAK. When you or Marg attack my deductive argument by saying the conclusion is "invalid" or that it is not "logical," you either 1) don't understand what these terms mean in the context of deductive logic or 2) are using the terms improperly in the context of this debate. I will try to give you both the benefit of the doubt and assume you aren't trying to back-peddle, now that it may have just recently occured to you that you used these terms improperly, but let's not rule that out as a possibility.JAK wrote:He who asserts has the responsibility to prove or offer compelling evidence.
Nice assertion, now where's your evidence?JAK wrote:Now, you demonstrate misunderstanding of deductive reasoning. You also appear to misunderstand how a valid, trustworthy Major Premise can be established.
What a ridiculous accusation. Anyone reading my responses can see why. Not to mention neither one of you has yet to address the context of the original post I made, clearly indicating I was never out to prove anything. And I am the one accused of being decietful!JAK wrote:You titled a post: “Logic Lessons for JAK and Marg.” She took you up on that topic as did I.
Now, lets get some terms straight... in what sense do you mean the words "took," "you," "up," "on," "that," "topic," "as," "did," and "I"? I wouldn't want to "misunderstand" you again....

Aquinas,
Your post is no response to the particulars of my analysis.
Previously I posted response with direct quotes from you:
JAK to Aquinas,
You make many “if” statements in your writing. A central dilemma is with the establishment of the “if” construction. Another problem is assertion as substitute for transparent evidence of support.
Doing this is what we call truth by assertion.
Example Aquinas:
Quote:
If in God, all goodness resides (thus to say of an object "A" that it is good, means that it participates in God's goodness in some way) and truth is good, then truth necessarily leads to God, since in God all goodness resides. The goodness of truth itself is found by following true things. Thus, given these explainations (explanations), here is an argument:
1. In God all goodness resides
2. all truth is good and
3. Therefore, truth leads to God
This is valid and logical, even if you don't find it at all compelling. The problem now is, that you Jak, charged the conclusion in this argument as being invalid, and Marg later patted you on the back for it:
JAK:
You have neither established “valid” or “logical” by merely asserting such. What do we need for reliable conclusion? We need clear, transparent evidence. You fail to offer any.
Quote Aquinas:
Right. And Aquinas established nothing. Superb analysis -- that if the major premise is not established, the conclusion is invalid. And, your correct “(Aquinas’) conclusion can not be relied upon.”
This is a misunderstanding of logic. Not establishing truth in a major premise has nothing to do with validity, because validity is about an argument's form; your problem is with soundness. If you would have accused my argument of not demonstrating anything true, because the soundness cannot be know with ill defined terms, I would conceed (concede) that you are right. By saying the premises are nonsense, or false, you imply that you know the meaning of the terms already, and the burden of proving this accusation lies on you. Marg accused the premises as being nonsense many times. She has yet to demonstrate why. She also accused the argument as not being logical, but the valid form of the argument is what makes it deductive logic, it does not depend on whether the premises are true.
What I want to know is this: why am I not allowed to write assertions in deductive order, when Marg is allowed to make comments like this (this was taken from a different thread than the one already cited):
JAK:
Aquinas,
you have the faulty understanding here as evidenced by Roget's New Millennium™ Thesaurus.
Validity is not so constrained or marginalized as you claim. It is not about “argument’s form” alone. It is inclusive of terms here represented.
In the thesaurus mentioned above are some definitions for the word valid. Among the definitions are genuine, correct, examining.
Your narrow use (understanding) of the word valid could be ameliorated by looking through the results in the website I cited above.
See these references to valid:
accurate, attested, authentic, authoritative, binding, bona fide, cogent, compelling, conclusive, confirmed, convincing, credible, determinative, efficacious, efficient, good, in force, irrefutable, just, legitimate, logical, original, persuasive, potent, powerful, proven, right, solid, sound, stringent, strong, substantial, telling, tested, true, trustworthy, ultimate, unadulterated, unanswerable, uncorrupted, weighty, well-founded, well-grounded
He who asserts has the responsibility to prove or offer compelling evidence. The definitions above from this on-line dictionary clearly demonstrate your notion of “valid” is faulty.
marg speaks well for herself. You can quote her and address her remarks. I have so done with your remarks (several posts) and see no refutation.
Now, you demonstrate misunderstanding of deductive reasoning. You also appear to misunderstand how a valid, trustworthy Major Premise can be established. I’ll not repeat what I previously posted to you regarding that, but I addressed it. You have not responded (that I can find). It seems this bb is tedious to navigate, and I may not have seen a direct response from you in which you quote in context what I stated and respond.
If you want to discuss forms only for deductive reasoning, using words like “God,” “truth,” and “good” are very poor. Why? They are poor because there is serious lack of consensus on what any of those words mean in the context of religious reference. And as you have use them, they are words out of the language of religious dogma.
So, you need words which have some universal understanding.
-------------------
JAK to Aquinas,
While there is more to your post and since you do not respond to my rejoinders, I’ll end quotations here.
Attacking marg (ad hominem) in no way benefits any position you may take. Namecalling only diverts attention from issues which might be addressed.
How is evidence established? What are reliable methods for establishing evidence? How can we assemble numerous pieces of evidence to draw conclusions which are reliable?
If that was your intended focus, much better illustrations could have been used to keep the focus on that. I’m skeptical that it was your intention to focus only on rational thinking.
marg referred to a website, <A HREF="http://www.philosophypages.com/lg/e08a.htm">this one</A> which has multiple internal links addressing language and logic.
You titled a post: “Logic Lessons for JAK and Marg.” She took you up on that topic as did I.

JAK:
He who asserts has the responsibility to prove or offer compelling evidence.
Acquinas responded:
Nice assertion, now where's your evidence?
JAK:
A fundamental principle of establishing anything is the principle of the burden of proof. That is not an “assertion” as you claim, it’s a fundamental principle of science.
See how reliable results are obtained.
Centuries ago, those who claimed the earth was a sphere had the burden of proof. They made a claim which went against the prevailing perception. That burden of proof was met. Today, nearly everyone in the educated world recognizes the earth is a sphere.
Any claim or assertion made carries with it the burden of proof for that claim. It is not up to skeptics to offer anything unless and until those who make a claim offer clear, transparent evidence for their claims. Hence, the burden of proof is on the affirmative.
JAK wrote:

Aquinas stated:
Nice assertion, now where's your evidence?
JAK:
I’ve explained the standard principle not an “assertion” as you state.
If I say to you: Little green men live on the moon, you should say: What is your evidence for your claim?
When Jonas Salk claimed he had a vaccine against polio, he had the burden of proof to establish the reliability of that vaccine. He did that in a series of tests which ultimately used humans. The humans who received his vaccine against polio did not get polio. In a relatively short time, medical science accepted that vaccine and polio was virtually eliminated where the vaccine was used.
Acauinas, that is meeting the burden of proof.
The principle is not a “nice assertion” absent evidence. Evidence supports the principle regarding how we humans establish valid conclusion which is reliable.
Burden of proof has long been established and places the responsibility on those who make claims.
In my previous example (green men on moon), I am unable to present transparent, clear evidence for my claim. Rational people should reject the claim about green men on the moon.
I failed to meet the burden of proof.

JAK:
I am someone, and your responses are unclear and fail transparancy test. If you are not “out to prove anything,” why are you making claims?
Thus far, you fail to establish any of the claims you have made. both marg and I have pointed to your flawed thinking.
You have not addressed the analysis which has been made regarding your statements.
I quoted above the complete text from which you lifted a few lines.. You did not address the analysis nor did you respond to the critique of your flawed thinking.
