Idea of Dualism comes from two structures that constitute a human. Those are: The Body and the Soul.
The Body: Mortal / Divine part of humans / Created before body / It does not change.
The Soul: Immortal / Mutable part of humans / Receives life from the soul / Ignorance.
Parts of the soul
Is the superior part of the three solus, it is in the head; is the one in charge to keep in balance and to control the parts. Is the one who is apart of the feelings, is the nucleus of the thoughts and the wills. Its immoral, its virtue is the prudence.
We have it in our hearts, his first priority is to dominate the value. It is on the middle of both souls, a good conduct takes to the intellectual soul, but a bad conduct takes to the desirous soul. Is with the body so this is mortal. His virtues is the force, the honor and courage.
Is the one that fulfil all the basic needs. It is joined to the body so it is mortal. In there it exist the pleasures, appetites and sensible wishes. (Sex, food, fame, richness, etc)
