In Plato's philosophical teachings, anthropologists dualism can be found, a concept that starts from the premise that the human being would be composed of the body, linked to the World of the Sensible, and the soul, which has connections with the World of the ideas. With this and seeing the body as, simply, the origin of evil, which also shows ignorance, Plato declares that it functions as a kind of prison for the soul and that the latter is completely alien to the process of incarnation through which it passes. This, basically, can be reduced to the fact that the soul would be in opposition to the body, representing the good, the wisdom and the ideas.
In developing his concept, Plato explains how the soul is the divine part of being; what really makes you human. This has an immutable quality, that is, it is not modified, in any way, by the adventures in which the body is found and it is immortal. The body, for its part, from birth is considered as mutable, it is mortal; to this are attributed all the evils (or that used to be considered as evils in classical times), such as love affairs, ignorance, enmities and fights.
The soul, for its part, consists of at least three sections, called the intellective soul or logistike, which is in charge of balancing and regulating the functions of the other sections, considering itself the supreme and immortal (unlike the other two); the irascible soul or thynmoeides, is one that is "carried in the heart", and that is defined by virtues such as honor, courage and strength; Finally, the concupiscible soul or epithymetike, is one that is in charge of the basic functions and cycles of the organism, so that the being can subsist.
