ΜΕΣΟΣ ΟΡΟΣ

LEXARITHMOS 955

The concept of the Mean Term (μέσος ὅρος), fundamental to Aristotelian ethics and logic, represents the ideal balance and correct judgment. It is not merely an arithmetic average, but the golden mean between two extreme states, leading to virtue and truth. Its lexarithmos (955) suggests a complex harmony, a combination of limits and a center that characterizes the pursuit of wisdom.

Definition

The "μέσος ὅρος" (mean term or middle term) is a complex concept that plays a central role in ancient Greek philosophy, particularly in the work of Aristotle. Literally, it means "the middle limit" or "the average term." However, its significance extends far beyond a simple arithmetic average, acquiring deep philosophical, ethical, and logical dimensions.

In Aristotle's ethical philosophy, as developed in the "Nicomachean Ethics," the mean term is the "μεσότης" (mean), the virtuous state that lies between two extreme vices: excess and deficiency. For instance, courage (ἀνδρεία) is the mean between cowardice (δειλία, deficiency) and recklessness (θρασύτης, excess). This mean is not a static, mathematical average, but a dynamic choice, relative to the individual and circumstances, requiring practical wisdom (φρόνησις) and correct judgment. It is the "mean relative to us" (πρὸς ἡμᾶς μέσον), meaning the mean appropriate for each individual.

In logic and dialectic, especially in the "Prior Analytics," the mean term (μέσος ὅρος) refers to the middle term of a syllogism. It is the term that connects the two extremes (the major and minor terms) and allows for the conclusion to be drawn. For example, in the syllogism "All men are mortal, Socrates is a man, therefore Socrates is mortal," "man" is the middle term that connects Socrates to the attribute of being mortal. Without the middle term, the syllogism cannot function.

Thus, the mean term is a concept that unifies Aristotelian thought, providing a framework for understanding both ethical action and logical inference. It represents the pursuit of balance, precision, and correctness across various fields of human experience and knowledge.

Etymology

MESOS OROS ← μέσος + ὅρος (compound word from two Ancient Greek roots)
The word "μέσος ὅρος" is a compound noun derived from two distinct Ancient Greek roots: "μέσος" and "ὅρος." The root of "μέσος" (MES-) is found in numerous words denoting the intermediate, the center, or balance. The root of "ὅρος" (OR-) is related to the concept of a boundary, definition, or determination. Both roots belong to the oldest stratum of the Greek language. Their combination creates a new meaning that transcends the sum of its parts, indicating a defined intermediate point or a determined middle state.

From the root MES- derive words such as μεσότης (mean, moderation), μεσάζω (to be in the middle), μεσημβρία (midday), μεστός (full). From the root OR- derive words such as ὁρίζω (to define, limit), ἀφορισμός (aphorism, definition), προσδιορισμός (determination), ὁρισμός (definition). The co-existence of these roots in "μέσος ὅρος" highlights the Greek tendency to synthesize concepts through the fusion of existing semantic cores.

Main Meanings

  1. The intermediate point, the center — The most basic, literal meaning, referring to something located between two extremes.
  2. The mean, the virtuous state (Aristotle) — In ethics, the ideal balance between excess and deficiency, leading to virtue.
  3. The middle term (Aristotle) — In logic, the term that connects the two extremes of a syllogism and enables the conclusion to be drawn.
  4. Measure, proportion — The correct quantity or quality, the avoidance of extremes.
  5. Rule, standard — That which is considered normal or acceptable, the average level.
  6. Agreement, mediation — In negotiations, the solution found midway between two opposing positions.
  7. Arithmetic mean (mathematics) — The numerical average, though this usage is later than the philosophical one.

Word Family

MES- (root of μέσος, meaning "intermediate") and OR- (root of ὅρος, meaning "limit, definition")

The word family around "μέσος ὅρος" develops from two distinct yet complementary roots: the MES- root denoting the intermediate or center, and the OR- root denoting a limit or definition. The combination of these roots creates a rich semantic field that explores balance, delimitation, and correct judgment. Each member of the family illuminates a different aspect of this complex concept, from simple location to ethical virtue and logical structure.

Philosophical Journey

The concept of the mean term, though systematically articulated by Aristotle, has its roots in earlier Greek notions of harmony and balance.

6th-5th C. BCE (Pythagoreans)
Pythagoreans
Pythagorean philosophers introduce the concept of harmony and proportion (mean proportion) in the cosmos and music, laying the groundwork for the idea of the mean.
5th C. BCE (Plato)
Plato
Plato, in "Philebus" and "Republic," examines the concept of measure and proportion as elements of good and order, though he does not use the term "μέσος ὅρος" with Aristotelian precision.
4th C. BCE (Aristotle)
Aristotle
Aristotle systematically develops the concept of the mean term both in ethics ("Nicomachean Ethics") as "μεσότης" and in logic ("Prior Analytics") as the "μέσος ὅρος" of the syllogism.
Hellenistic Period
Hellenistic Schools
The Aristotelian concept of the mean continues to influence ethical schools, such as the Stoics, who adopt the idea of moderation and the avoidance of extremes.
Byzantine Period
Byzantine Commentators
Byzantine commentators and philosophers preserve and interpret Aristotelian texts, safeguarding the concept of the mean term and its application in ethics and logic.
Renaissance and Modern Era
Revival of Aristotelianism
The revival of Aristotelianism in Europe brings the "mean term" back to the forefront of philosophical thought, influencing ethics and epistemology.

In Ancient Texts

Three characteristic passages from Aristotle, where the mean term plays a central role:

«ἔστιν ἄρα ἡ ἀρετὴ ἕξις προαιρετική, ἐν μεσότητι οὖσα τῇ πρὸς ἡμᾶς, ὡρισμένῃ λόγῳ καὶ ᾧ ἂν ὁ φρόνιμος ὁρίσειεν.»
Virtue, then, is a state of character concerned with choice, lying in a mean, i.e., the mean relative to us, this being determined by a rational principle, and by that principle by which the man of practical wisdom would determine it.
Aristotle, Nicomachean Ethics, Book II, Ch. 6, 1106b36-1107a2
«λέγω δὲ μέσον ὅρον μὲν τὸν καὶ ἐν ἄλλῳ καὶ ἐν ἄλλῳ ὄντα, καὶ αὐτὸν ἐν μέσῳ.»
By middle term I mean that which is itself in another and another in it, and which is itself in the middle.
Aristotle, Prior Analytics, Book I, Ch. 25, 42a37-38
«τὸ γὰρ μέσον ἄριστον ἐν πᾶσι.»
For the middle is best in all things.
Aristotle, Politics, Book IV, Ch. 11, 1295b29

Isopsephic Words (955)

Words from the Liddell-Scott-Jones lexicon with the same lexarithmos (955) as "μέσος ὅρος," but from different roots:

κατασκευή
"Κατασκευή" (955) means "construction, preparation." Its isopsephy with "μέσος ὅρος" might suggest that finding the mean term is a process of "constructing" virtue or logical truth.
ὁμιλέω
The verb "ὁμιλέω" (955) means "to converse, associate with." Its connection to the "mean term" can be interpreted as the necessity of dialogue and communication to find common ground or a middle solution.
προγυμνασία
"Προγυμνασία" (955) means "preliminary exercise." This suggests that achieving the mean term, whether in ethics or logic, requires preparation and practice, a process of learning and refinement.
ὑποκάρδιος
"Ὑποκάρδιος" (955) means "under the heart, deep within the heart." Its isopsephy with "μέσος ὅρος" might imply that the true understanding of the mean term as a virtue stems from an internal, heartfelt sense rather than merely external rules.
ἐπίκουρος
"Ἐπίκουρος" (955) means "helper, ally" and is also the name of the philosopher Epicurus. The connection could be ironic, as Epicurus had a different approach to ethics than Aristotle, but it could also suggest that the mean term is a "helper" in the pursuit of eudaimonia.
θερμοκύαμος
"Θερμοκύαμος" (955) is a type of bean. The presence of such a mundane word among philosophical terms highlights the randomness of isopsephy, but also the universality of numerical relationships that permeate every aspect of language.
