For Plato, the soul is the self. Plato perceives the human person to be made up of the body and soul. The soul consists of three parts: rational soul, spiritual soul, and appetitive soul. The rational soul is found in the head, it allows the person to think; while the spiritual soul can be found in the chest which allows the person to express their emotional feelings. Thirdly, the appetitive soul. It is found in the abdomen of a person, this allows a person to express their physical needs.
