It that were true, Septic would not have to post the identical false argument 8 times in one day to establish it. Nor post the same false argument hundred's of times over the years.

It's about time you wake up and learn a few things about the principles of valid argument. 8^) > I'm > betting he's got a definition of argumentum ad ignorantium in there Well DUH, that's what I have been telling you about all this time, brother, theist argument _ad ignorantiam_ (and you keeep trying to change the subject). Argument from ignorance, also known as _argumentum ad ignorantiam_ or as Copi shows it in _Introduction to Logic_, "argument _ad ignorantiam_," is a logical fallacy (a fallacy of relevance) in which one argues for some hypothesis or another [some 'might be' conjecture] based on that hypothesis not having been proven false. It is a form of trying to shift the burden of proof. It is logical fallacy for which theists have been FAMOUS since at least Galileo's time, as Copi explains: <quote> Famous in the history of science is the argument _ad ignorantiam_ given in criticism of Galileo, when he showed leading astronomers of his time the mountains and valleys on the moon that could be seen through his telescope. Some scholars of that age, absolutely convinced that the moon was a perfect sphere, as theology and Aristotelian science had long taught, argued against Galileo that, although we see what appear to be mountains and valleys, the moon is in fact a perfect sphere, because all its apparent irregularities are filled in by an invisible crystalline substance. And this hypothesis, which saves the perfection of the heavenly bodies, Galileo could not prove false! Galileo, to expose the argument _ad ignorantium_, offered another of the same kind as a caricature. Unable to prove the nonexistence of the transparent crystal supposedly filling the valleys, he put forward the equally probable hypothesis that there were, rearing up from the invisible crystalline envelope on the moon, even greater mountain peaks -- but made of crystal and thus invisible! And this hypothesis his critics could not prove false. </quote> (Copi and Cohen, _Introduction to Logic_) [in this case the term, 'hypothesis' means conjecture, a speculative, 'might be' imagining with no basis in fact.] Quote

Copi says you're utterly wrong. Copi [1953, 56] "Introduction to Logic" "The fallacy of argumentum ad ignorantiam is illustrated by the argument that there must be ghosts because no one has ever been able to prove that there aren't any. The argumentum ad ignorantiam is committed whenever it is argued that a propostion is true simply on the basis that it has not been proved false, or that it is false because it has not been proved true." Several important points here that illustrate how off the beam your viewpoint has been. 1. Note the use of the term "must" "...there MUST be ghosts because no one has ever been able to prove that there aren't any." Copi is talking about definitive conclusions of proof based on ignorance or lack of proof to the contrary. 2. Note the use of the term "argued." "....The argumentum ad ignorantiam is committed whenever it is ARGUED that a proposition is true simply on the basis that it has not been proved false..." Copi does not include the notion of "might be/might not be" in his definition. And he wisely notes that the Argument from ignorance must be an ARGUMENT. It is not a statement, it is not a question. It is an argument. Since your entire spew is based on the idea of "maybe's and might be's" and since you presume that even a question or a statement can be an Argument from ignorance, you're clearly WRONG. Now, don't you feel better? Quote

And Septic tries to claim that when one says "there might (or might not) be an X because no one has shown that there must not be ( or must be) and X, that one is committing that fallacy, which is , in itself, the fallacy of argumentum ad hominem. It is logical fallacy for which Septic has been INFAMOUS since at least Galileo's time. Quote
