a) So, besides their own faws that they must discard, do spirits also have to struggle against the infuence of matter?
“Yes, the lower the spirit, the tighter the link between spirits and matter. Do you not see? No, humans do not have two souls; there is only one soul in a single being. The souls of animals and those of humans are distinct from one another, so that the soul of the one cannot animate the body created for the other. While human beings do not have animal souls that place them on the same level as the animals, they do have animal bodies, which often drag them down. Their bodies are endowed with life and have instincts that are unintelligent and limited to their survival.”
When they incarnate in human bodies, spirits contribute the intellectual and moral principles that make them superior to animals. The two natures in humans, intellect and morality, constitute two distinct sources of passions, one springing from the instincts of their animal nature and the other due to the impurities of the spirit, which are in sympathy with the rudimentary nature of animal desires. As spirits become purifed, they gradually free themselves from the infuence of matter. While under that infuence, they come close to the nature of animals. When delivered from that infuence, they raise to their true destination.
