As an expert in philosophy and psychology, I can provide you with an answer that is commonly accepted in the context of classical philosophical thought, particularly as it pertains to the works of Plato and other ancient Greek philosophers.

In Platonic philosophy, the soul is often divided into three parts, which are:


1. Reason (Logos): This is the rational part of the soul, responsible for thinking, understanding, and decision-making. It is associated with wisdom and is considered the highest part of the soul.


2. Spirit (Thumos): This is the spirited part of the soul, which is associated with emotions such as anger and courage. It is often seen as the part that drives us to defend our beliefs and values.


3. Appetite (Epicrasia): This is the desiring part of the soul, which is responsible for our physical desires and appetites, such as hunger, thirst, and sexual desire. It is the most mortal part of the soul and is associated with the body.
