ΟΡΕΚΤΙΚΟΝ

LEXARITHMOS 645

Orektikon, a pivotal term in Aristotelian psychology and ethics, refers to the desiderative or appetitive faculty of the soul. It is not merely hunger for food, but the broader capacity of the soul to incline towards something, to desire, to pursue. Its lexarithmos (645) suggests a complex balance between attraction and pursuit.

Definition

The ὀρεκτικόν (a substantivized adjective derived from ὀρέγω, 'to stretch out, to desire') is a central term in ancient Greek philosophy, particularly in Aristotle's psychology and ethics. It denotes the desiderative or appetitive faculty of the soul, i.e., the capacity to incline towards something, to pursue, or to avoid. Aristotle, in his works «Περὶ ψυχῆς» (On the Soul) and «Ἠθικὰ Νικομάχεια» (Nicomachean Ethics), distinguishes the ὀρεκτικόν as one of the primary functions of the soul, responsible for desires, appetites, and volitions, and closely connected with movement and action.

Within the framework of Aristotelian psychology, the ὀρεκτικόν is not a monolithic power but encompasses various forms of desire, such as ἐπιθυμία (sensory appetite), θυμός (spirited impulse), and βούλησις (rational wish). The proper functioning of the ὀρεκτικόν, meaning its alignment with right reason (ὀρθὸς λόγος), is crucial for achieving virtue (ἀρετή) and flourishing (εὐδαιμονία). Education and ethical training aim at shaping the ὀρεκτικόν to desire the good things indicated by reason.

Beyond philosophy, the term can also be used in a more general sense for anything that stimulates appetite or desire, whether for food or other pursuits. In modern Greek, the word «ορεκτικό» (orektikó) is primarily used for food that stimulates the appetite, thus retaining the original sense of 'exciting desire'.

Etymology

ὀρεκτικόν ← ὀρεκτός ← ὀρέγω ← ὀρεγ- (Ancient Greek root)
The root «ὀρεγ-» is an Ancient Greek root belonging to the oldest stratum of the language, without external comparisons. Its basic meaning is 'to stretch, to extend, to reach out,' from which the concept of 'pursuit, desire' developed. The verb ὀρέγω gives rise to the adjective ὀρεκτός ('that which is desired') and from this, with the addition of the suffix -ικός, the adjective ὀρεκτικός is formed, denoting the quality or power related to appetite or desire. The substantivization of the adjective into ὀρεκτικόν (τὸ ὀρεκτικόν) designates the specific faculty or part of the soul.

The root «ὀρεγ-» has generated a family of words covering both the physical act of stretching and the mental state of desiring. From the verb ὀρέγω comes the noun ὄρεξις, denoting the act of reaching out or desire. Other derivatives include the adjective ὀρεκτός, meaning 'desirable,' and compound verbs such as προορέγομαι. In philosophical terminology, ὀρεκτικόν is closely linked to concepts such as ἐπιθυμητικόν and θυμοειδές, which, although not direct morphological derivatives of the root «ὀρεγ-», are parts of the same psychic structure described by Aristotle.

Word Family

oreg- (root of the verb ὀρέγω, meaning "to stretch, to desire")

The Ancient Greek root «ὀρεγ-» expresses the concept of extension, stretching, and by extension, pursuit and desire. From an initially physical movement ('to stretch out the hand') it evolved into a mental inclination ('to desire something'). This root is fundamental to understanding human will and passions in ancient philosophy, producing words that describe both the act and the capacity for desire. Its development within the Greek language demonstrates how abstract concepts can arise from concrete ones.

ὀρέγω verb · lex. 978
The basic verb of the root, meaning 'to stretch out, to extend' (e.g., the hand) and metaphorically 'to desire, to pursue, to long for'. In Homer (Iliad, A 226) it is used for stretching out hands, while later it acquires a strong psychological dimension.
ὄρεξις ἡ · noun · lex. 445
The act of stretching or pursuing; desire, appetite, longing. In Aristotelian philosophy, it is the general concept of desire, encompassing ἐπιθυμία, θυμός, and βούλησις. (Aristotle, «Περὶ ψυχῆς»).
ὀρεκτός adjective · lex. 765
That which is desired, enviable, longed for. It describes the quality of the object of desire, that towards which the ὀρεκτικόν tends. (Plato, «Politeia»).
ἐπιθυμητικόν τό · noun · lex. 1002
The appetitive part of the soul, associated with bodily appetites and sensory desires. In Plato and Aristotle, it is one of the three parts of the soul, often the lowest, and is a subcategory of the ὀρεκτικόν. (Plato, «Politeia»).
θυμοειδές τό · noun · lex. 743
The spirited part of the soul, associated with courage, anger, and honor. It is also one of the parts of the soul in Plato and Aristotle, and belongs to the broader category of the ὀρεκτικόν, as a form of impulse. (Plato, «Politeia»).
προορέγομαι verb · lex. 549
A compound verb meaning 'to stretch out for something beforehand, to desire something before it happens, to anticipate desire'. It highlights the preemptive or anticipatory nature of desire.
Ἀριστοτέλης ὁ · noun · lex. 1224
The great Greek philosopher (384-322 BCE) who systematically developed the concept of ὀρεκτικόν as a central element of his psychology and ethics. His works, such as «Περὶ ψυχῆς» and «Ἠθικὰ Νικομάχεια», are the primary sources for understanding the term.
Περὶ ψυχῆς τό · noun · lex. 2103
One of Aristotle's most important works, in which he analyzes the nature of the soul and its faculties, including the ὀρεκτικόν. It constitutes the foundational treatise for ancient Greek psychology and the understanding of the desiderative function.

Philosophical Journey

The concept of ὀρεκτικόν, while having roots in older notions of desire, gains its full philosophical dimension with Aristotle, profoundly influencing Western thought:

8th-6th C. BCE
Homeric and Archaic Era
The verb ὀρέγω is primarily used with the physical meaning of 'to stretch out, to extend' (e.g., hands), but also metaphorically for the pursuit of honor or power. The concept of mental desire is present but not systematically categorized.
5th-4th C. BCE
Plato
Plato distinguishes parts of the soul, such as the ἐπιθυμητικόν and the θυμοειδές, which are precursors to Aristotle's ὀρεκτικόν. However, the term ὀρεκτικόν itself is not used in the same systematic sense.
4th C. BCE
Aristotle
Aristotle establishes ὀρεκτικόν as a fundamental faculty of the soul in his works «Περὶ ψυχῆς» and «Ἠθικὰ Νικομάχεια». He defines it as the soul's capacity to pursue or avoid, distinguishing its forms (ἐπιθυμία, θυμός, βούλησις).
Hellenistic Period
Stoics and Epicureans
Philosophers of this period continue to analyze desires and passions, often building on Aristotelian terminology but with different approaches to ethics and psychology.
Roman and Byzantine Eras
Medicine and Scholasticism
The term is used in medical texts for substances that stimulate appetite and in philosophical commentaries on Aristotle, maintaining its original meaning.
Modern Era
Modern Greek Usage
In Modern Greek, the word «ορεκτικό» has predominantly come to mean 'an appetizer,' losing its direct connection to the psychological concept of the desiderative faculty of the soul.

In Ancient Texts

Aristotle is the primary source for understanding ὀρεκτικόν:

«ἔστι δὴ τὸ ὀρεκτικὸν ἐν τῇ ψυχῇ, καὶ τοῦτο τὸ κινοῦν.»
There is then the desiderative faculty in the soul, and this is what moves.
Aristotle, De Anima B 3, 414b 2
«τὸ μὲν γὰρ ὀρεκτικὸν καὶ ὅλως τὸ ἐπιθυμητικὸν καὶ ὀρεκτικόν, ἔχει πως λόγου.»
For the desiderative, and in general the appetitive and desiderative part, somehow shares in reason.
Aristotle, Nicomachean Ethics A 13, 1102b 30
«τὸ ὀρεκτικὸν τῆς ψυχῆς, ὅπερ ἐστὶν ἄλογον.»
The desiderative part of the soul, which is irrational.
Aristotle, De Anima Γ 10, 433a 25
