Positive atheism, also called strong atheism and hard atheism, is the form of atheism that asserts that no deities exist; negative atheism, also called weak atheism and soft atheism, is any other type of atheism, i.e. where a person does not believe in the existence of any deities and does not explicitly assert that there are none.
Hmm Wikipedia - continuing to use top quality sources for your information I see.
Nonetheless - I remain rather unclear about the distinction. The only way I can rationalise the distinction is about belief (or lack of) and knowledge. So what this seems to be saying is that in your terms weak atheists don't believe in god or gods (but don't claim to know for sure) while strong atheists claim to know they don't exist.
Yes, I think that sums it up well.
If that's the distinction then I don't think I've ever met a strong atheist and even Dawkins doesn't fit the bill. And actually given the impossibility of proving a negative anyone claiming to know gods don't exist (i.e. a strong atheist) would be pretty limited intellectually.
Just out of interest are there any atheists here who claim to know that gods don't exist. I don't think so.
When he was here, The Stranger did. I think Sir Bernard Quatermass did too. There were some on the old BBC boards, but I've deleted the records I kept of those posts.
I think there are one or two still here, but I wouldn't want to put any words into people's mouths.
Actually, it is possible to prove a negative, at least some of the time. If you mean it is impossible to prove that no gods exist, I could well agree, but then we might have a long, drawn out discussion on what "prove" means!
