‘My soul and myself’ examines Plato's understanding of the soul. While Plato in general defends the idea that the soul is immortal, so that its relation to the body is merely temporary, we find conflicting suggestions about the nature of this relation. Sometimes the soul appears as the body's ruler and director; sometimes as its unhappily trapped prisoner. One of the most famous passages in Plato is his division of the soul into three ‘parts’ or aspects in the Republic. The main function of this theory is to show that the good life is one in which reason rules the whole soul.
