ΕΝΘΥΜΗΜΑ

LEXARITHMOS 553

The enthymeme, a pivotal term in rhetoric and philosophy, denotes a thought, an idea, or, most notably, a syllogism developed "within the *thymos*"—that is, in the mind or soul. Aristotle famously defined it as the rhetorical syllogism, the "body of persuasion," which relies on probable premises rather than certain truths. Its lexarithmos, 553, is numerically linked to the concept of internal processing and logical structure.

REPORT ERROR

Definition

According to the Liddell-Scott-Jones Lexicon, ἐνθύμημα originally signifies "a thought, consideration, idea" (Pl. Phd. 66b, X. Mem. 1.1.19). Its meaning evolved significantly, particularly within Aristotelian philosophy and rhetoric.

In classical Greek, ἐνθύμημα refers to an internal mental process, a thought arising from the *thymos* (the soul or spirit as the seat of thought and emotion). It is not merely a fleeting idea but a thought that has undergone some form of processing or deliberation.

Its most specialized and renowned usage is in Aristotelian rhetoric, where the enthymeme is defined as the "rhetorical syllogism" (Arist. Rh. 1.1.11, 1355a). Unlike the scientific syllogism, which is based on necessary and true premises, the enthymeme proceeds from probable or commonly accepted premises (*endoxa*), making it suitable for persuasion in an audience setting. Aristotle considers it the "body of persuasion" (Rh. 1.1.11).

Etymology

«enthymeme ← enthymeomai ← en- + thymos» (root thym-)
The word ἐνθύμημα derives from the verb ἐνθυμέομαι, which is formed from the preposition ἐν- ("in, within") and the noun θυμός. The root thym- is an Ancient Greek root belonging to the oldest stratum of the language, originally denoting "soul, spirit, disposition," and by extension, the "seat of thought and emotion." The compound with ἐν- emphasizes the internal nature of the thought or processing.

From the same root thym- derive many words describing states of mind, soul, or disposition. The verb ἐνθυμέομαι means "to consider, reflect, ponder," while ἐνθύμησις is the "act of thinking." Other cognate words, such as προθυμία ("eagerness, readiness") and ἀθυμία ("despondency"), illustrate how different prefixes can alter the meaning of the basic root of *thymos*, whether as spirit or disposition.

Main Meanings

  1. Thought, consideration, idea — The general sense of an internal mental process.
  2. Recollection, remembrance — The act of bringing something to mind.
  3. Reflection, deliberation — Active and deep thought on a subject.
  4. Argument, proof — In rhetorical discourse, a means of persuasion.
  5. Rhetorical syllogism (Aristotle) — The specific technical meaning as a syllogism based on probable premises.
  6. Maxim, precept — A thought formulated as a principle or teaching.
  7. Plan, intention — A thought leading to action.

Word Family

«thym- (root of θυμός, meaning 'spirit, soul, disposition, thought')»

The root *thym-* is fundamental in Ancient Greek, referring to the soul, spirit, impulse, courage, and also the seat of thought and emotion. From this root arise words describing both internal mental processes and external manifestations of disposition or inclination. The addition of prefixes such as *en-*, *pro-*, *a-*, or *eu-* further differentiates the meaning, creating a rich family that explores the diverse aspects of human inner life.

ἐν preposition · lex. 55
The preposition *en*, meaning 'in, within'. It forms the first component of ἐνθύμημα, emphasizing the internal nature of the thought that takes place 'within' the mind or soul. It is widely used throughout ancient Greek literature.
θυμός ὁ · noun · lex. 719
The core root of the word, meaning 'soul, spirit, disposition, courage,' and by extension, the seat of thought and emotion. In Homer, *thymos* is the source of life and impulse, while later it is more closely associated with will and thought. (e.g., Homer, *Iliad* A 24).
ἐνθυμέομαι verb · lex. 630
The verb from which ἐνθύμημα is derived, meaning 'to consider, reflect, ponder.' It describes the active process of internal thought or the examination of a subject. (e.g., Thucydides, *Histories* 1.140).
ἐνθύμησις ἡ · noun · lex. 922
The act of thinking, reflection, recollection. It differs from ἐνθύμημα in that *enthymesis* is the process, while *enthymema* is the result or content of the thought. (e.g., Plato, *Sophist* 263d).
ἐνθυμητικός adjective · lex. 1112
Pertaining to thought, reflective, contemplative. It describes the quality of someone or something capable of deep thought or that provokes thought. (e.g., Aristotle, *De Anima* 430a).
προθυμία ἡ · noun · lex. 710
Eagerness, readiness, willingness. Formed from *pro-* ('before, forward') and *thymos*, indicating a positive disposition or impulse towards something. (e.g., Thucydides, *Histories* 2.87).
ἀθυμία ἡ · noun · lex. 461
Despondency, lack of courage or spirit. Formed from the privative *a-* and *thymos*, describing the opposite state of eagerness or vigor. (e.g., Plato, *Laws* 630c).
εὔθυμος adjective · lex. 1124
Cheerful, in good spirits, good-tempered. Formed from *eu-* ('well') and *thymos*, indicating a good or positive disposition of the spirit. (e.g., Xenophon, *Anabasis* 3.1.22).

Philosophical Journey

The trajectory of the enthymeme reflects the evolution of Greek thought, from its initial meaning of internal reflection to its specialized rhetorical application.

8th-6th C. BCE
Homeric Era
The root *thym-* is already central, referring to the soul, spirit, or impulse. The compound word ἐνθύμημα had not yet formed, but the basis for internal thought existed.
5th C. BCE
Presocratics and Sophists
The word appears with the general meaning of thought or idea. The Sophists began exploring the structure of argument, paving the way for later developments.
4th C. BCE
Plato
Uses ἐνθύμημα in the sense of thought or idea, often in contrast to sensations or external impressions (e.g., "τὰ ἐνθυμήματα καὶ τὰς δόξας" in *Phaedo* 66b).
4th C. BCE
Aristotle
Establishes the technical meaning of ἐνθύμημα as the "rhetorical syllogism" in his *Rhetoric*. He defines it as the core of persuasion, emphasizing its distinction from the scientific syllogism.
3rd C. BCE - 2nd C. CE
Hellenistic and Roman Periods
The Aristotelian usage remains dominant in rhetorical theory. The word is also used with the general meaning of thought or recollection in philosophical and historical texts.
3rd - 5th C. CE
Patristic Literature
Appears sporadically in Christian texts, retaining the meaning of thought or internal process, often in an ethical or spiritual context.

In Ancient Texts

Three characteristic passages highlight the different uses of ἐνθύμημα in ancient literature.

«τὸ δ' ἐνθύμημα συλλογισμός τις»
The enthymeme is a kind of syllogism.
Aristotle, Rhetoric 1.1.11 (1355a)
«τὰ ἐνθυμήματα καὶ τὰς δόξας»
thoughts and opinions
Plato, Phaedo 66b
«τὰς τῶν ἀνθρώπων ἐνθυμήσεις»
the thoughts of men
Xenophon, Memorabilia 1.1.19

Isopsephic Words (553)

Words from the Liddell-Scott-Jones lexicon with the same lexarithmos (553) but different roots, offering a glimpse into the numerical harmony of the Greek language.

διανόησις
The term «διανόησις» (553), meaning 'thought, understanding,' derives from the root *nous*. While *enthymema* focuses on reasoning, *dianoesis* emphasizes the mental process of comprehension, showing a parallel yet distinct path to knowledge.
νοητέον
«νοητέον» (553), the impersonal verbal adjective of νοέω, means 'that which must be thought or perceived.' It connects to intellectual apprehension and understanding, complementing the concept of *enthymema* in its intellectual dimension.
ὁμόλογος
«ὁμόλογος» (553), meaning 'agreeing, unanimous,' comes from the root *logos*. Although of a different root, its isopsephy with *enthymema* is interesting, as both relate to the structure of discourse and persuasion, one as a syllogism and the other as agreement.
φάγημα
«φάγημα» (553), meaning 'food, sustenance,' derives from the verb φάγω. Its numerical connection to *enthymema* is an example of the unpredictable harmony of isopsephic words, as it concerns material nourishment in contrast to intellectual sustenance.
βοτάνιον
«βοτάνιον» (553), meaning 'small plant, herb,' comes from the root βοτάνη. Its isopsephy with *enthymema* highlights the diversity of words sharing the same number, bringing together the world of nature with that of thought.
