If anything such a statement is contemptible in the eyes of science and educated thought because you are basing an argument of a blind assumption and ignorance.

Proof of nonexistance requires an absolute viewpoint of reality or of the situation that would allow for absolutely no error. Jsut because ther is no proof does not mean that it doesn't exist.
Excellent response, thank you. Let it be known that the statement is not one that I myself made. :)

I love myself sometimes:cool:

If you agree with the above, you should vote 'False'.
Though a strong argument can be made by simply showing that existence would contradict facts or laws.

For example, science has done nothing to disprove the existence of a creator (in some form), it has only perhaps removed the necessity of a creator's existence.

However, science does offer evidence against the existence of a God who exactly matches, completely and literally, the God in the King James bible. That God's existence contradicts physical laws (miracles, resurrection of the dead), the age of the universe, and the fossil record (dinosaurs). None of this proves the non-existence of this particular god, but does show that either the KJV is nor 100% literally true or its god is free to ignore physical laws and likes to mess with our minds by creating fossils of non-existent creatures and messing with their carbon dates.
Perfect. :)

This is why I love OT. Why the hell do I bother with the mental midgets of P&N?! :confused:

The wording makes no sense at all.

If you were to say, "There is no proof that X does not exist. Therefore, I can conclude that X exists", or, "There is no proof that X exists. Therefore, I can conclude that X does not exist.", then I could see how that would be a logical fallacy. But the way that you wrote it isnt' even a fallacy, the sentence doesn't make sense to begin with.

Sorry, I can only offer what I've got there. But if I said...

"There is no proof that X does not exist. Therefore, I can conclude that X exists."

...what would you say?

Am I having deja vu or did you start another thread? :/

Edit: (This is taken from the other thread :p... you know, the one like three polls ago? :p)


False
The absence of evidence does not suggest an outcome in either direction.

Oh and as others have said it really depends on the context.
In a closed environment where the system is known in its entirety, then it is easy to make such claims.

In other situations such as approaching the universe with the scientific method approach we look at things differently. For example, we do not know the whole of the universe. We do not even know how many "layers of onions" the laws of physics may go down. Laws of the universe (physics), for example, can never be proven as complete and absolutely correct.

Just the same, we cannot prove the non-existance of phenomenon. HOWEVER, we do take certain preconceived views based on what our experience through experimentation and our own logic lead us to believe based on relative probability.

For example, using what we know about the universe so far and what I perceive, I think it is safe to ASSUME with a high probability that the core of the earth is not held together by the feces of ants. It very well could be, and I cannot prove it either way, but I have a strong suspicion that it is not. The non-exitstence of evidence does not let me come to any factual and concrete conclusion, however. I cannot say with certainty what the center of the earth is comprised of.

That would be a logical fallacy, since you cannot prove a negative. You can directly prove that it does exist, but you cannot directly prove that it doesn't exist.

My answer to the reworded OP is maybe, it depends on circumstances and other factors.

You can only rationalize one way or the other, but at some point you make a decision based on what you believe the evidence points to. It's obvious we can replace X with God in this case. Some people choose to believe one way or the other based on what they believe makes the most sence. People tend to disagree at this point :)

Basically, I conclude that since I cannot prove that God does not exist, I cannot conclude that he does not exist.

He really needs to change the wording, because the way it's written now makes no sense and is most likely a typo.

I can only think that he's mocking someone who doesn't believe in God, and he's saying that their reason is that they have no proof that God doesn't exist, yet they can somehow conclude that God doesn't exist.

But in that case, the first poster on this page would be right, that "therefore" doesn't make sense in this usage, and "yet" should be used instead.

This was the original statement I clarified:
[yllus] said it was unreasonable to say X doesn't exist because you can't prove X doesn't exist.
What do you say to that?

The reason it doesn't make sense is because it relies on ignorance to remain true.


"If something cannot be proven, it does not exist," is ignorance at its finest, and many of us will not permit such a tragedy...


give yourself a pat on the back for me;)

What do you say to that?


I'd say that's a logical fallacy, since you can never prove the non-existence of anything. It's just not possible. Even asking the question is invalid, since you'd be asking for an impossibility.

I can't prove that a magical green dragon isn't sitting next to me. You can't prove negatives.

false.

there's no known cure for cancer. that doesn't mean it doesn't exist.

FALSE, are you sure you didnt misword what you were trying to say.

On a related note, you can mathematically produce statments that can not be proven or disproven. Statements for which you can proove the impossibility of showing either their truth or falsehood.

Yes! What's remarkable is that you can then choose to include an "impossible to prove or disprove" statement into your system as an axiom. Or choose to have it be a false statement. Then you are left with a new larger mathematical system.

And in this new system, you can create new statements that are not provable or disprovable.

In other words, no matter how big your mathematical system is, you can always produce statements that cannot be proved or disproven within the system. It's like some invisible barrier that keeps us from ever knowing everything.
