Plato's tripartite soul and more!

Here's my collage of Plato's view of the soul as compared to other versions of the soul. Some of the images in the collage are metaphorical, or are representations of the soul. These images are not meant to be interpreted directly.

Based on Plato's version of the soul, how does he see the human condition?
Plato's version of the soul is broken into three parts: reason, passion(appetite), and spirit. The role of the reason part of the soul is to rule over and control appetite and spirit. The fact that Plato had to create a whole part of the soul in order to control the appetites of man suggests that Plato had a negative view of human nature. Without reasoning to control the appetites, or desires, the soul would not be harmonious or just. The fact that reasoning controls the other parts of the soul also suggests that Plato thought that humans needed to have extreme control over their bodies, and focus on their mind through reasoning. This would make sense because Plato obviously was a philosopher and he therefore held the view that education and training of the mind was necessary in order to obtain goodness through justice or harmony in the mind.

The other souls in the collage can be considered to have been influenced by Plato's version of the soul. Most of the souls in the collage are separated into more than one part, an idea that can be traced back to Plato's three-part soul. However, the souls in the collage have different parts that Plato's. Plato combines his highest, most spiritual parts of the soul, reason and spirit, with corruptive appetite.  However, the Christian and Sikh souls do not specifically address the damaging parts of the soul, like appetite. This would suggest that these versions of the soul have a more positive, hopeful opinion of the human soul and condition.
