Many a man is mad in certain instances, and goes through life without having it perceived. For example, a madness has seized a person of supposing himself obliged literally to pray continually; had the madness turned the opposite way, and the person thought it a crime ever to pray, it might not improbably have continued unobserved.

— Samuel Johnson
