For when nature is strong, and of the proper temperament, it rules all and commands all, whether humour, spirit (pneuma), or solid, and, by their good order and symmetry, regulates the man in life; but if the bond of nature—that is to say, its tone—be dissolved, then this affection is produced. The original of it is causus, which is in this form.
