Agnosticism

[Angrboda]

On a very quick reading -I've got to run- I'd say that it clearly is not the case that every atheist is an agnostic. A "7" or anti-theist makes absolute knowledge claims in which I detect no provisionalism. Perhaps it is a failure in my understanding but i'll have to think more of this later.

You missed the part where I redefined what we mean by knowledge to something that, while we have great confidence in it, is still fallible and provisional. Even a "7" would admit that, if by some miracle, they were provided with satisfactory evidence that they had been wrong about God, they would change their belief. (I don't know that a "1" would.) We claim that we know that nothing travels faster then the speed of light, that gravity exists, and that the earth is older than 4,000 years old. If we were to discover tomorrow that we had been mistaken about anything we consider knowledge, the practical man would simply acquit himself of the old belief and get on with the business of embracing this new "knowledge," whether it be of gravity or of God. (The theologian and apologist, I can't be as sure of. They do not strike me as practical fellows.) So, in answer to your question, no, a "7" would not be an exception to this, unless said "7" felt their belief that god does not exist is infallible, and those such 7's probably shouldn't be setting the tone for the rest.
