Thumos, also spelled Thymos (Greek, Ancient (to 1453);: θυμός), is the Ancient Greek concept of (as in "a spirited stallion" or "spirited debate"). The word indicates a physical association with breath or blood and is also used to express the human desire for recognition. It is not a somatic feeling, as nausea and dizziness are.
In Homer's works, thumos was used to denote emotions, desire, or an internal urge. Thumos was a permanent possession of living man, to which his thinking and feeling belonged. When a Homeric hero is under emotional stress, he may externalize his thumos and converse with or scold it.[1] Achilles, in the Iliad, cares for his own honour; he keeps gods and deities in his heart; "...the thunderous lord of Hera might grant you the winning of glory, you must not set your mind on fighting the Trojans, whose delight is in battle, without me. So you will diminish my honour (thumos)."[2]
Democritus used "euthymia" (i.e. "good thumos") to refer to a condition in which the soul lives calmly and steadily, being disturbed by no fear, superstition, or other passions. For Democritus euthymia was one of the root aspects of the goal of human life.
Plato's Phaedrus and his later work The Republic discuss thumos as one of the three constituent parts of the human psyche. In the Phaedrus, Plato depicts logos as a charioteer driving the two horses eros and thumos (erotic love and spiritedness are to be guided by logos). In the Republic (Book IV) soul becomes divided into (See Plato's tripartite theory of soul):[1]
Plato suggested we have three parts of our soul, which in combination makes us better in our destined vocation, and is a hidden basis for developing our innate ideas. Thumos may draw from this to strengthen man with our reasoning, this tripartite division is as follows:
"Megalothymia" refers to the need to be recognized as superior to others, while "isothymia" is the need to be recognized as merely equal to others. Both terms are neoclassical compounds, coined by Francis Fukuyama. In his book The End of History and the Last Man, Fukuyama mentions "thymos" in relation to liberal democracy and recognition. He relates Socrates' ideas about Thymos and desire to how people want to be recognized within their government. Problems emerge when other people do not recognize another's Thymos, and therefore do not provide the justice that it requires. In order for people to exist in harmony, Fukuyama argues, isothymia rather than megalothymia must be used to satisfy the human need for recognition. Any system that creates political inequality is necessarily feeding the megalothymia of some members while denying it to others. Fukuyama explains how Thymos relates to history with the example of anti-communism in relation to the Soviet Union, Eastern Europe, and China. He states, "We cannot understand the totality of the revolutionary phenomenon unless we appreciate the working of thymotic anger and the demand for recognition that accompanied communism's economic crisis."[3]
Hyperthymia, dysthymia, cyclothymia, and euthymia (medicine) are mental/behavioral conditions in modern psychology.
