The Meaning of Thumos

Thumos was the part of the soul located in the chest that generated emotion, courage, and the will to fight.‍​‌​‍​‍​‌​‍​‍​‌​‍​‍​‍​‌​‍​‌​‍​‍​‍​‍​‌​‌​‍​‌​‍​‌​‌​‍​‌​‍​‍​‍​‍​‌ In Homer, thumos is where a hero feels rage, makes decisions, and debates with himself. Odysseus speaks to his own thumos, urging it to endure. Achilles's thumos drives him to fury when Agamemnon takes Briseis. Unlike the modern Western notion of emotions as irrational disruptions of thought, thumos for the Greeks was a legitimate voice — it could be right or wrong, but it was always worth hearing. Plato later systematized this into his tripartite soul: reason (logos) in the head, appetite (epithumia) in the belly, and spirit (thumos) in the chest. The just person, Plato argued, is one where reason governs with thumos as its ally against appetite. Warriors cultivated thumos; philosophers sought to direct it. It was never meant to be extinguished, only properly channelled.

Fun Fact

The thymus gland in your chest is named after thumos — the ancients located spirit and courage in the same area.
