A Bodily Map of Emotion: Head, Chest, and Belly

The chapter's central question

Body maps make the differences in the abstract mind visible to your eyes. The head symbolizes far-sighted contemplation, the heart symbolizes the heat of honor and anger, and the stomach symbolizes the desire for survival and pleasure. This arrangement also captures the fact that emotions are not just events in our thoughts, but are experienced as postures, breathing, heat and impulses.

Plato also surprisingly intuitively described where the three parts of the soul reside in our body.

'Reason', a cool-headed judge, lives in the highest place, 'Head' and loves wisdom. ‘Pride (pride, courage)’, a bodyguard who cannot tolerate injustice, takes up residence in the ‘chest’ where the heart beats and blood boils, and guards the commands of reason. And the primal 'desire' to eat, drink and rest is likened to an untamed beast chained to the 'belly and liver' side below the diaphragm.

When you are treated unfairly, your heart is pounding and your fists are clenched, these are physical signs that the bodyguard in your heart is boiling with a sense of justice after hearing the warnings of reason. Plato understood 2,300 years ago that emotions are not just floating ideas, but living, breathing, organic reactions directly linked to our body's blood flow and heartbeat.

Context and nuance

Plato's theory of emotions is not organized in a single, independent theoretical book. The full picture is revealed only when the theory of justice in Republic, the soul and love in 『Phaedrus』, and the theory of eros in 『The Feast』 are read together. Emotion is not a lump on the other side of reason; it is a matter of how the different forces of the soul form an order.

However, this map is not a physiological explanation that the location of organs directly produces specific emotions. It is more of a symbolic language layered with ancient medical and political metaphors. The important question is not ‘where are the emotions?’ but rather ‘what role does each force play for the common good life?’

Do not oversimplify it this way

Plato's image of the head, chest, stomach and two horses should not be read like an anatomy diagram of modern brain science. This is a philosophical model that shows the conflict and educability within the soul. Also, fixating the black horse as evil and the white horse as good misses the point of the metaphor. The power of desire is also necessary to move one's life, and the key is not elimination but attunement.

Philosophy in life

I'm on a diet, but at 11pm, I smell ramen and think, 'I have to endure it!' and 'Let's eat it just for today!' Have you ever been tormented in between?

When resentment and anger are rampant: Acknowledge that ‘the white horse (spirit, pride) inside me has risen up bravely to protect me.’
