There are in the brain viscidities in which is mingled something spirituous or vital, and these viscidities, expelled from the blood there, fall first among the meninges, then among the fibers, part of them into the great ventricles of the brain, and so on. The spirits who relate by correspondence to those viscidities which have something spirituous or some life in them, appear almost directly above the middle of the head at a mid distance, and are such that from habit acquired in the life of the body they stir scruples of conscience, and intrude in matters of no conscience, and in this way burden the conscience of the simple.
