ΟΡΕΞΙΣ

LEXARITHMOS 445

Orexsis (ὄρεξις), a foundational concept in ancient Greek philosophy, describes the soul's inherent tendency or desire towards something. Ranging from simple physical urges to rational volition, it constitutes the driving force behind human action and the pursuit of the good. Its lexarithmos (445) suggests a deep connection to the order and balance that desire often seeks.

Definition

According to the Liddell-Scott-Jones Lexicon, ὄρεξις (a feminine noun) primarily means 'a stretching out, reaching after' and by extension 'desire, appetite, longing.' In classical philosophy, this concept acquires central significance, describing the soul's innate tendency or impulse towards an object or a goal.

In Plato, ὄρεξις is often associated with the 'appetitive' (ἐπιθυμητικόν) part of the soul, the source of bodily desires and passions, which requires control by the rational part. However, the concept is not limited to lower desires but can also include the desire for knowledge or the good, although Plato more frequently uses 'ἔρως' for higher spiritual striving.

Aristotle systematically analyzes ὄρεξις as the genus of desire, subdividing it into three species: 'appetite' (ἐπιθυμία), 'spirit' (θυμός), and 'wish' (βούλησις). For Aristotle, ὄρεξις is the moving principle of action, as every action stems from some form of desire, whether rational or irrational. Understanding ὄρεξις is therefore crucial for his ethical philosophy, as a virtuous life requires the proper regulation and direction of desires.

Etymology

ὄρεξις ← ὀρέγω (to stretch out, reach for, desire) ← Proto-Indo-European root *h₃reg- (to straighten, to stretch)
The word ὄρεξις derives from the verb ὀρέγω, meaning 'to stretch out, reach for, long for.' The primary meaning suggests a physical movement towards an object, an extension of oneself towards something external. This physical motion is psychologically translated into an internal impulse or desire. The Proto-Indo-European root *h₃reg- is widely distributed across Indo-European languages, connecting the concept of desire with straightness, direction, and order.

Cognate words include the Latin *regere* (to guide, rule), *rex* (king), and *rectus* (straight, right), the Sanskrit *ṛjú* (straight), and the German *recken* (to stretch). In Greek, related terms also include ὀρεκτικός (appetizing, desirous), ὀρέγω (to stretch, desire), ὀρεκτός (desirable), and ὄρος (mountain, from the sense of raising, stretching upwards).

Main Meanings

  1. Physical stretching, reaching out — The original, literal meaning of the word, describing the act of extending one's hand or body towards something.
  2. Appetite, general desire — A natural inclination or longing for something, often physical, such as hunger or thirst.
  3. Psychological impulse, urge — An internal force that propels an individual towards an action or an object, not necessarily conscious.
  4. Irrational desire, passion (Plato) — The part of the soul responsible for bodily pleasures and impulses, often in opposition to reason.
  5. Genus of desire (Aristotle) — The broader category encompassing appetite (ἐπιθυμία), spirit (θυμός), and wish (βούλησις), as the moving principle of action.
  6. Prohairesis, rational volition — The conscious and rational choice stemming from a desire for the good, as defined by Aristotle.
  7. Tendency, inclination — The inherent direction or predisposition of a thing or person towards a specific purpose or state.
  8. Demand, claim — A strong desire or assertion for something to be given or done.

Philosophical Journey

Orexsis, as a philosophical term, traverses the history of ancient Greek thought, evolving from a simple physical concept into a central pillar of psychology and ethics.

8th-6th C. BCE
Archaic Period
In Homeric epics and early poetry, ὄρεξις is primarily used in its literal sense of 'stretching' or general 'longing' for something, often on a physical level.
5th-4th C. BCE
Plato
Plato develops the concept of ὄρεξις as part of the soul's 'appetitive' (ἐπιθυμητικόν) part, responsible for bodily desires and irrational impulses. He emphasizes the need for reason to control this desire to achieve justice and harmony of the soul (Republic).
4th C. BCE
Aristotle
Aristotle offers the most systematic analysis of ὄρεξις, defining it as the genus of desire that includes appetite (ἐπιθυμία), spirit (θυμός), and wish (βούλησις). He considers ὄρεξις the moving principle of all action, whether rational or irrational, and central to his ethical philosophy (De Anima, Nicomachean Ethics).
3rd C. BCE - 2nd C. CE
Stoic Philosophers
The Stoics understand ὄρεξις as the initial impulse (ὁρμή) towards an object. They distinguish rational desires from irrational ones, which they characterize as passions (πάθη, e.g., desire, fear). Self-control (ἐγκράτεια) and apathy (ἀπάθεια) are central to their ethics, requiring the control of irrational desires.
3rd C. BCE - 2nd C. CE
Epicurean Philosophers
Epicureans focus on satisfying natural and necessary desires (ὄρεξις) to achieve pleasure (ἡδονή, as absence of pain) and ataraxia. They categorize desires into natural and necessary, natural but not necessary, and neither natural nor necessary, advocating for the avoidance of the latter.
3rd C. CE - 6th C. CE
Neoplatonism
In Neoplatonism, ὄρεξις acquires a more spiritual dimension, as the soul's inherent tendency to return to its source, the One or the Good. It is a metaphysical longing for union with the divine, a higher form of desire that transcends material needs.

In Ancient Texts

Orexsis, as a fundamental concept, frequently appears in the works of great ancient philosophers, highlighting the complexity of the human soul and action.

«τὸ μὲν ἐπιθυμητικὸν τῆς ψυχῆς, ᾧ πεινῶμεν καὶ διψῶμεν καὶ ταῖς ἄλλαις ὀρέξεσι χρώμεθα...»
“the appetitive part of the soul, by which we hunger and thirst and use other desires...”
Plato, Republic IV, 437b
«τὰ δὲ ζῷα πάντα ἔχει ψυχῆς μόριον τὸ ὀρεκτικόν.»
“all animals have the desiderative part of the soul.”
Aristotle, De Anima II, 3, 414b2
«ἔστι γὰρ ἡ προαίρεσις ὄρεξις βουλευτικὴ τῶν ἐφ' ἡμῖν.»
“for choice is deliberative desire of things within our power.”
Aristotle, Nicomachean Ethics VI, 2, 1139a31-33
