The Laboratorium

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.
