On atheists and agnostics had this to say
The agnostic is an atheist. The atheist is an agnostic. The agnostic says; ‘i do not know but I do not believe there is any god. The atheist says the same. The orthodox Christian says he knows there is a god: but we know that he does not know. The atheist (too) cannot know that god does not exist.
I think this settles the matter.
