IMMORTALITY DOES NOT EXTEND TO THE SUB-LUNAR SPHERE.
If we be right in attributing immortality to the heaven, we shall have to extend that conception to the stars it contains; for unless its parts endured, neither could the heaven. However, the things beneath the heaven do not form part of it. The region which constitutes the heaven does not extend further down than the moon. As to us, having our organs formed by the (vegetative) soul which was given us by the celestial divinities (the stars), and even the heaven itself,[210] we are united to the body by that soul. Indeed, the other soul (the reasonable soul), which constitutes our person, our "me,"[211] is not the cause of our being,[212] but of our well-being (which consists in our intellectual life). She comes to join our body when it is already formed (by the vegetative soul), and contributes to our being only by one part, by giving us reason (in making of us reasonable beings, and men).
