Touchstone—Making assumptions is not the basis of “circular” in logic. Circular logic is problematic because it is a restatement. Whether a premise is or is not defended is irrelevant to the arguments circularity.
This is your clue that you misunderstand – the qualifier for circularity is not what you suggest.
That is not the least bit circular as an argument. 3) is not a restatement of 1) (or 2).
This is indeed circular, but not because people would not accept 1) (circularity does not obtain from soundness or unsoundness of a premise!). It is circular because it is a restatement, and “goes both directions”.
What you have missed for circularity is the role the the conclusion in supporting the premise. Here, 2), your conclusion, is used to support 1) the premise. That’s the error; logically, we want to go from premise to conclusion, and the syllogism should stand on its own unidirectionally. In your “red ball” example, your conclusion 3) is not the guarantor of premise 1). There is not “reverse argumentation” that is the essence of circularity in reasoning.
A simple rule that can help test this principle is just to look and see if anything is added by the conclusion – is any putative new knowledge presented? In the red ball argument, there is new knowledge to be gained (assuming the soundness of the premises). We can now believe you are holding a red ball (we went from “seeing” to “believing”).
In the Bible example, your conclusion adds nothing over the premise, and as such is not an argument at all.
If I say:
On their own, neither 1) or 2) on their own is a problem in formal terms. It’s only when 1) is offered to support 2) which is in turn used to support 1) which then is used to support 2)… that the problem obtains (note the “because” used in both). It’s problematic precisely because it is NOT susceptible to challenge, but is trivially true.
- Paul’s words are true because they are in the Bible
- Paul’s words are in the Bible because they are in the Bible.
I note that tautologies and other circular forms are incredibly useful. They are trivial truths, though, just definitions. When offered in the context of arguments about the state of the real world, it’s an error, as the real world doesn’t enter into the equation, and no liability to challenge exists at all.
The Red Ball argument begins with a metaphysical claim as the premise, and then goes onto apply a concrete conclusion based on the physical particulars in 2). 3) doesn’t argue back to 1), chasing its tail as does the Bible argument. The Red Ball argument invites testing and challenge, which is what fundamentally separates it from the Bible argument, which admits of neither.

“Making assumptions is not the basis of “circular” in logic. Circular logic is problematic because it is a restatement. Whether a premise is or is not defended is irrelevant to the arguments circularity.”
Interesting, Touchstone…
How about the statement “The Iraq War was wrong because George W. Bush lied to the American People about Weapons of Mass Destruction and Saddam Hussein’s role in 9/11.”
Some would say that statement can be “defended” and some cannot.
Is that a circular argument??? Since the “defense” angle is “irrelevant.” does that make it a circular argument?
Actually, I would say no. Because to ME it is a matter of opinion that can be neither disproven or disproven. (Although some would disagree with me, of course.)
Not having to do with Logic.
BTW—
(One reason I asked this was NOT to start a political argument or rehash some old complaints of good folks on either side of the political spectrum. I don’t want the thread derailed. Please. Nor is it intended as a barometer of people’s feelings towards Dubya
—I personally voted for him in the 2004 election. And I was basically for the Iraq War-although I feel there were some major missteps that were made and bungling errors and stupidity on ALL sides.)
THE reason I asked was because I actually heard someone about a year ago reply to the above statement with the words “That is a circular piece of logic.”
It was a conversation at a party and I didn’t press it—but I remembered it when I read your statement and post, Touchstone.
So, what do YOU think??? Can it be said to be “circular logic?”
