Yes it is. And it's a offensive, evangelical religion at that as Barwell's

zealotry and intolerance demonstrate.

That is just like those theists of Galileo's time arguing _ad ignorantiam_

that there might be an invisible crystalline substance filling all the

valleys of the moon because that hypothesis [that 'might be' theist

conjecture] Galileo could not prove false! That is logical fallacy for which

you theists are FAMOUS, 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.

Wouldn't be a brain without that, would it, moron? When you all say 'help'

you aren't talking about blood supply to the cells (which any cell needs),

you are really arguing that there might be a metaphysical 'soul' thingy,

aren't you?

How would that help your side's argument _ad ignorantiam_ that it might be

the case that consciousness does not dwell exclusively in the brain because

there is no proof that hypothesis (that 'might be' theist conjecture) is

false?

Well, scores of academics and scientists disagree with you on that, Septic.

But your argument from ignorance seems to be that because we can't currently

come up with an exact description of consciousness, then consciousness must

be whatever you say it is.

 

A truly excellent example of the argumentum ad ignorantiam as described by

Copi and others.

That's just like a prosecutor arguing _ad ignorantiam_ in court, "Is the

accused actually not guilty as he claims? No one knows for certain." It is a

not-too-cleverly-disguised attempt at shifting the burden of proof, a form

of argument _ad ignorantiam_.

 

Remember, it is the MEANING of a statement such as that which really

matters, not the particular wording or rewording. Argument _ad ignorantiam_

is logical fallacy no matter how hard you try to disguise it.

Don't be silly. It is true. Anybody can read it for himself. The hypothesis

(the 'might be' theist conjecture with no basis in fact) is that all the

moon's apparent irregularities are filled in by an invisible crystalline

substance, and the argument _ad ignorantiam_ is, "And this hypothesis (this

'might be' conjecture) Galileo could not prove false!"

 

<quote>

Galileo, to expose the argument _ad ignorantium_, offered another of the

invisible crystalline envelope on the moon, even greater mountain peaks --

but made of crystal and thus invisible! And this hypothesis his critics

Sure it would. In autopsies, the brain is quite regularly removed from

the rest of the remains. Presumably after all consciousness has also

left the remains. But it is still the brain.

 

So it is moronic of Septic not to be aware of that.

Septic seems to want to put his words in my mouth.

 

Can a physical brain maintain consciousness when in physical isolation

from it physical body?

 

Septic seems to want to say "yes".

We agnostics accept both halves. Septic doesn't.

Sure it would. Unless Septic is implying that there is something more

to a brain than its physical presence.

Septic seems to be arguing for souls, but I have no belief in 'souls",

whatever Septic supposes them to be.

I don't know why Septic keeps claiming that his side is our side. No one

on "our side" has said anything about where "consciousness dwells", or

how it dwells or anything else.

 

We merely ask by what authority, or evidence, Septic claims to know that

"consciousness dwells exclusively in the brain".

 

And Septic keeps avoiding our question.

Apparently Septic claims to know for certain, or to know someone who

does know for certain, as he rebukes Dan for saying otherwise, but

Septic will not divulge how he came by that knowledge.

For Septic to argue that that is an argumentum ad ignorantiam, Septic

must be arguing that someone DOES know for certain.

 

Well do you know for certain, Punk?

Do you know of anyone who does know for certain, Punk?

Does Septic know for certain?

Does Septic know someone who knows for certain?

 

If it is the case no one knows for certain, wherein lies any fallacy in

asking the question.

 

So Septic is WRONG! AGAIN! AS USUAL!!!

The entire quote was "Does consciousness dwell exclusively in the brain? No

one knows for certain."

 

That is a question, a proposal of possibility, not a statement of fact or

opinion. I find it a perfectly reasonable hypothesis that consciousness may

extend into the spinal cord, even into the nerve endings. It is almost

always reasonable to doubt established ideas.

Blah blah.. strawmen

 

If stating that an unproven hypothesis might be true is argument from

ignorance then the entirety of human knowledge owes it's existence to such

fallacies.

 

The sensible meaning of this fallacy is a making a statement that claims

something is_true because it has not been disproven, not that it might be

possible.

What's wrong with Copi's explanation that arguing _ad ignorantiam_ that

there might be X because there is no proof that hypothesis (that 'might be'

conjecture) is false is argument from ignorance, logical fallacy for which

theists are FAMOUS, 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

transparent crystal supposedly filling the valleys, he put forward the

equally probable hypothesis that there were, rearing up from the invisible

Not a thing. The problem is you don't understand it.

For one thing, Copi never"explains any such thing.

 

Copi does say

"It is a fact that the moon is a perfect sphere

because Galileo can't prove otherwise"

is an argumentum ad ignorantiam.

 

Copi is honest enough not to say

"It might be a fact that the moon is a perfect sphere

because Galileo can't prove otherwise"

is an argumentum ad ignorantiam.

 

Septic, on the other hand, is dishonest enough to say that

"It might be a fact that the moon is a perfect sphere

because Galileo can't prove otherwise"

is an argumentum ad ignorantiam.

 

Not only that, Septic says it repeatedly, in spite of having the his

lies repeatedly brought to his attention by any number of posters.

There is no proof necessary in order to say that something might be true

unless there is existing proof to the contrary. That's not a fallacy. That

does NOT mean that we take such hypotheses seriously, that WOULD be

fallacious.

Why don't you stop trying to change the subject? That's not the proposition

being discussed here. The proposition being discussed here is the theist

proposition that there might be consciousness without a brain (an immortal

soul, or something), as Woodie phrases the theist argument _ad ignorantiam_,

"Nobody can prove the negative, that there is no consciousness outside the

brain."

I don't buy that. According to the logic textbook, _Introduction to Logic_

you and Virgil and friends are mistaken, arguing _ad ignorantiam_ that there

might be something because there is no proof the hypothesis (the 'might be'

conjecture) is false is logical fallacy for which theists are FAMOUS, 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.

[in this case the term, 'hypothesis' means conjecture, a speculative, 'might

be' imagining with no basis in fact.]

You are mistaken. You just can't seem to make yourself face the fact that

hypothesis means 'might be' conjecture in this case.

What's wrong with Copi's explanation that arguing _ad ignorantiam_ that

there might be X because there is no proof that hypothesis (that 'might be'

conjecture) is false is argument from ignorance, logical fallacy for which

theists are FAMOUS, as Copi explains:
