Madness is consistent; which is more than can be said for poor reason. Whatever may be the ruling passion at the time continues equally so throughout the whole delirium, though it should last for life. Madmen are always constant in love; which no man in his senses ever was. Our passions and principles are steady in frenzy; but begin to shift and waver, as we return to reason.
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.
