To be an atheist is to maintain God. His existence or his nonexistence, it amounts to much the same, on the plane of proof. Thus proof is a word not often used among the Handdarata, who have chosen not to treat God as a fact, subject either to proof or to belief: and they have broken the circle, and go free. To learn which questions are unanswerable, and not to answer them: this skill is most needful in times of stress and darkness.
Radical agnosticism? Everything I oppose. "We can't know if there's a God in the abyss, so I shall not leap" is the same as to say "there is no God, so I shall not leap"--a choice against faith. But conscientious agnosticism claims impartiality, making it more false than atheism.
