I have been instructed that the spirits of Mars have reference in the Greatest Man to what is mediate between the intellectual and the voluntary faculties, thus to thought from affection; and the best of them to the affection of thought. It is for this reason that their face acts as one with their thought, and that they cannot dissemble before any one. And as they have reference to this in the Greatest Man, the middle province, which is between the cerebrum and the cerebellum, corresponds to them. For with those with whom the cerebrum and the cerebellum are conjoined as to spiritual operations, the face acts as one with the thought; so that the very affection of the thought shines forth from the face, and from the affection, with the aid of some signs going forth from the eyes, the general of thought shines forth. For this reason when the spirits of Mars were with me, I perceived sensibly a drawing back of the front part of the head toward the occiput, thus of the cerebrum toward the cerebellum.# # Human faces on our earth in ancient times received influx from the cerebellum, and the faces then acted as one with the interior affections of man but that afterward they received influx from the cerebrum, when man began to dissemble and counterfeit in the face affections not his own, and concerning the changes brought upon faces therefrom in process of time (n. 4325-4328).
