Spirits properly so called are only those who love to speak and are mediums of the speech of many. These are also divided up into kinds and species, as well as into classes. They want to be called intelligence, or knowledge, and think they are the only ones who know, indeed who control all things, each in a different way. At each level there are such spirits, to whom pertain the spiritual matters; yet they think little, although they believe they think more than others. But I cannot as yet enumerate the different kinds among them.
