Both, actually. Strong atheism makes the stronger claim, weak atheism makes the weaker claim. It's obvious to me that one of the statements makes a logically stronger (more constrained) claim than the other. It's so obvious to me that I'm gonna have to think a bit about how to present this to someone who doesn't comprehend it. Get out of what? You make it sound like I'm some sort of craazy claim. "I do not believe that God exists" --> If you made a list of all the things I believe, "I believe that God exists" would not be one of them. The statement makes no claim on the existence of "I believe that God does not exist" on this list of things that I do believe. It might be there, but it also might not. This is the weaker of the two statements, since it is not as constrained. Things you might find on my list: "I believe that I was born in Poland", "I believe that 2+2 is 4", and so on. "I believe that God does not exist" --> makes the claim that "I believe that God does not exist" is on the list of things that I believe... for sure. If I had to produce such a list, I would include "I believe that God does not exist". Now, you, as a believer, might have a hard time understanding the difference between the two. To you, you either believe that God exists, or you don't. I understand that.. But the difference is essentially what differentiates Strong atheism vs weak atheism and to a lesser degree atheism vs agnosticism. Agnostics do not believe that God exists.. They make no positive claim that God exists, therefore they do not believe that God exists. However, an agnostic also does not believe the opposite.. Thus, to say that an agnostic "believes that God does not exist" would be incorrect. I jumped on this because in order to really understand my opinion on the question of God, you sort of have to understand this important distinction. So many people out there try to lump people into two camps.. "YOu either believe or you don't!".. but that's just not how it works, and if you do that, you will never understand my stance on the subject. Since the purpose of these forums is an exchange of ideas, and since God comes up fairly frequently in our discussions, you should make a point of understanding this distinction.. saving you the embarassment of fighting strawmen in the future (ie. making claims about my beliefs or lack thereof that are just incorrect) If you are unable to address my points without flaming, then perhaps you do not belong in this (heated??) debate.
