ΘΕΡΜΟΤΗΣ

LEXARITHMOS 732

Thermotēs (θερμότης), one of the primary qualities of the cosmos according to ancient Greek philosophers, was not merely the sensation of warmth but a fundamental force shaping matter and life. From Empedocles' cosmic elements to Galen's humoral balances in medicine, thermotēs served as a central axis of scientific thought. Its lexarithmos (732) suggests a complex, active, and transformative power.

Definition

In ancient Greek philosophy and science, thermotēs (ἡ) was not merely a sensation but an essential quality and power associated with motion, life, and change. For Empedocles, thermotēs was one of two motive forces (along with psychos, cold) that caused the separation and combination of the four "roots" (elements). Later, Aristotle integrated it into the system of four primary qualities (hot, cold, dry, moist), considering it an active and formative principle, in contrast to psychos which was passive and destructive.

Thermotēs was also inextricably linked with the concept of fire, one of the four elements, and was considered responsible for the creation and maintenance of life. In medicine, particularly within the Hippocratic and Galenic traditions, the balance of heat in the body was crucial for health. Excessive or insufficient thermotēs could lead to illnesses, such as fever (also referred to as thermotēs) or chilling.

Beyond physics and medicine, thermotēs could also be used metaphorically to describe intensity, zeal, or passion, although this usage was less common than its literal and scientific meanings. The word underscores the central position of heat as a fundamental principle for understanding the natural world and the human body in ancient thought.

Etymology

θερμότης ← θερμός ← θερμ- (Ancient Greek root belonging to the oldest stratum of the language)
The root "therm-" is an Ancient Greek root belonging to the oldest stratum of the Greek language, with no indications of borrowing from other languages. It describes the property of being "hot" or "warm" and forms the basis for a series of words related to heat, warming, and thermal properties. Its meaning has remained consistent throughout the historical trajectory of Greek.

From the root "therm-" many words are derived that retain the basic concept of heat. The adjective "θερμός" (hot, warm) is the direct source of the noun "θερμότης". The verb "θερμαίνω" (to heat, warm) describes the action of heating, while the noun "θέρμη" refers to the quality of heat itself. Other compound words, such as "θερμολουσία" (warm bath) or "θερμοπώλιον" (a shop selling hot drinks), illustrate the application of the concept to practical aspects of daily life.

Main Meanings

  1. Physical heat, warmth — The literal meaning of heat as a physical property or sensation.
  2. Primary quality (natural philosophy) — One of the four fundamental qualities (along with cold, dry, and moist) that compose elements and substances, according to Aristotle and other philosophers.
  3. Fever, elevated body temperature (medical) — In medical terminology, especially in the Hippocratic and Galenic traditions, thermotēs refers to the state of fever or the internal heat of the body.
  4. Active principle, motive force — Heat as the force that causes motion, change, dissolution, or combination in matter, in contrast to cold which is considered passive.
  5. Zeal, passion, intensity (metaphorical) — Metaphorical use to describe spiritual or emotional intensity, enthusiasm, or fervor.
  6. Heating, process of warming — The action or result of heating, as in technical or practical applications.

Word Family

therm- (root of the verb θερμαίνω, meaning "hot, warm")

The root "therm-" forms the core of a significant family of words in Ancient Greek, all related to the concept of heat, warmth, and heating. Originating from the oldest stratum of the language, this root expresses a fundamental physical property and force. Its derivatives cover a wide range of uses, from describing a physical state to heating processes and metaphorical meanings of zeal. Each member of the family highlights a different aspect of the primary concept.

Philosophical Journey

The concept of heat, as a fundamental principle, spans ancient Greek thought from the Presocratics to late antiquity, evolving from a cosmic force to a medical factor and a philosophical quality.

6th-5th C. BCE
Presocratic Philosophers
Heraclitus identifies the cosmos with eternal fire, while Empedocles includes Fire (hot and dry) as one of the four "roots" (elements), with heat being one of the two motive forces of the world.
4th C. BCE
Aristotle
Aristotle systematizes heat as one of the four primary qualities (hot, cold, dry, moist), which combine to form the four elements. He considers it an active and formative principle.
5th-4th C. BCE
Hippocratic Medicine
In Hippocratic texts, thermotēs is central to understanding health and disease. The balance of heat and cold in the body is considered essential for well-being, while fever is a manifestation of excessive heat.
3rd C. BCE - 2nd C. CE
Stoic Philosophy
The Stoics developed the concept of pneuma as a kind of warm, ethereal air or "craftsmanlike fire" that permeates and organizes the cosmos and living beings, making heat fundamental to their cosmology.
2nd C. CE
Galen
Galen, building upon Aristotle and Hippocrates, integrates heat into the theory of humors. Thermotēs, along with cold, dry, and moist, determines the properties of the humors and, by extension, the temperament and health of the individual.
Late Antiquity
Neoplatonism and Alchemy
In Neoplatonism, thermotēs retains its significance as a cosmic force. In early alchemical practices, heating and cooling were fundamental processes for the transmutation of substances, reflecting the ancient understanding of heat as a transformative power.

In Ancient Texts

The significance of heat as a primary quality and active principle is highlighted in texts by leading ancient thinkers:

«τὰς δὲ διαφορὰς τὰς τῶν σωμάτων τὰς κατὰ τὰς ποιότητας ἔχουσιν αἱ ἁφαὶ καὶ αἱ θερμότητες καὶ αἱ ψυχρότητες καὶ αἱ ξηρότητες καὶ αἱ ὑγρότητες.»
“The differences of bodies according to their qualities are due to the senses of touch and to heats and colds and drynesses and moistnesses.”
Aristotle, On Generation and Corruption II.3, 330a30
«τὴν δὲ θερμότητα καὶ τὴν ψυχρότητα καὶ τὴν ξηρότητα καὶ τὴν ὑγρότητα, ταῦτα γὰρ τὰ πρῶτα καὶ μέγιστα τῶν ἐν τῷ σώματι.»
“And heat and cold and dryness and moistness, for these are the first and greatest of the things in the body.”
Hippocrates, On Regimen in Acute Diseases 1
«τὸ πῦρ πνεῦμα θερμὸν καὶ ξηρόν ἐστι, καὶ τοῦτο τὸ πνεῦμα διὰ παντὸς τοῦ κόσμου διήκει.»
“Fire is a hot and dry spirit, and this spirit extends through the whole cosmos.”
Diogenes Laertius, Lives of Eminent Philosophers VII.136 (referring to Stoic physics)

Isopsephic Words (732)

Words from the Liddell-Scott-Jones lexicon with the same lexarithmos (732) but different roots, revealing the hidden connections within the Greek language:

ἀγνοητικός
"Ignorant, unknowing." The state of ignorance can be contrasted with the clarity brought by heat (e.g., the light of fire) or the understanding of natural principles that include heat.
ἀποτέλεσμα
"Result, effect." Thermotēs, as an active principle, is often the cause or force leading to a result or change, making this isopsephy conceptually interesting.
συγκίνημα
"Commotion, emotion, movement." Thermotēs is a force that causes motion and change. This isopsephy highlights the dynamic and active nature of heat, both in the physical and psychological realms.
δυσθηρία
"Difficulty in hunting, wildness." While seemingly unrelated, it could suggest uncontrolled or "wild" heat, such as a fever that makes the body "difficult" to tame, or heat as a force of untamed nature.
ἐκκύκληθρον
"Eccyclema, a stage device for revealing interior scenes." Heat, as a transformative force, can "reveal" or "bring to light" the hidden properties of substances, much as the eccyclema reveals what is hidden.
εὐπελαγής
"Easy to sail, open sea." The concept of ease and openness can be contrasted with the intensity or restrictive nature of excessive heat, or suggest the free flow of heat within a system.
