ΠΟΡΟΣ

LEXARITHMOS 520

The word πόρος, with its lexarithmos of 520, constitutes a fundamental term in ancient Greek thought, describing not only a physical passage but also a means, a way of achieving a purpose, or even a source of revenue. From philosophers seeking the "πόρος" of knowledge to economists studying the "πόρους" of the city, the word's meaning extends from the tangible to the abstract, underscoring the human capacity to find solutions and pathways.

Definition

According to the Liddell-Scott-Jones Lexicon, πόρος (ὁ) initially means "a passage, a way, a ford, a road." This primary sense refers to a physical point or path that allows transit, such as a river crossing or a strait. This meaning is evident in Homeric texts and early geographical writings, where a πόρος is a specific location that can be traversed.

Over time, the meaning of πόρος expanded metaphorically to encompass any "means" or "way" of achieving a purpose, an "escape route" from a difficulty, or a "solution" to a problem. In philosophy, particularly in Plato, πόρος can refer to the ability to find solutions or to resourcefulness, often contrasted with "ἀπορία" (perplexity or impasse).

In the economic sphere, πόρος acquired the meaning of "resource" as a source of revenue, wealth, or means of livelihood. Xenophon, for instance, uses the term to describe the financial resources of a city or a household. The word retains its dynamic quality, always implying movement, flow, and the capacity to find pathways, whether it be a physical passage or an intellectual or economic solution.

Etymology

πόρος ← root per- / por- (meaning "to pass through, to go across")
The word πόρος derives from an Ancient Greek root belonging to the oldest stratum of the language, per- / por-, which conveys the idea of passing through, traversing, or conveying. From this root, numerous words developed, all related to movement, passage, and the means that facilitate such movement. The vowel alternation (e-grade in per- and o-grade in por-) is a common phenomenon in Greek morphology, lending variety to its derivatives.

Cognate words sharing the same root include the verb πορεύομαι ("to go, to travel"), the noun πορεία ("a journey, a course"), and the adjectives ἄπορος ("impassable, without resources") and εὔπορος ("easy to pass, resourceful"). Further derivatives are ἔμπορος ("merchant, traveler") and ἐμπορία ("trade, commerce"), as well as πόρθμος ("strait, ferry") and πορθμεύς ("ferryman"). All these words retain the core meaning of "passage" or "means."

Main Meanings

  1. Passage, way, road — The literal meaning, referring to a physical path, road, or passage, often watery (e.g., a strait).
  2. Ford, river crossing, strait — A more specific usage for a point where one can cross a body of water, such as a river or a narrow channel.
  3. Means, way, expedient — A metaphorical meaning denoting a method of achieving a goal, a solution to a problem, or an escape from a difficulty.
  4. Resource, source of revenue, wealth — An economic meaning, referring to sources of income, capital, or more generally, means of livelihood and prosperity.
  5. Resourcefulness, ingenuity, ability to find solutions — A philosophical meaning, especially in Plato, where πόρος is the capacity to find ways and solutions, in contrast to ἀπορία (perplexity).
  6. Method, process — In certain contexts, it can refer to a systematic approach or a defined procedure for achieving an outcome.
  7. Pore (anatomical), channel — In later usage, particularly in medicine and biology, it refers to small openings or channels in the body or in materials (e.g., pores of the skin).

Word Family

per- / por- (root meaning "to pass through, to go across")

The root per- / por- is one of the most productive and fundamental roots in Ancient Greek, expressing the central idea of movement, passage, and the discovery of ways or means. From this root, words developed that cover a wide spectrum of concepts, from simple physical locomotion and its facilitators, to economic management and problem-solving. The variety of its derivatives highlights the flexibility of the Greek language to create complex meanings from a simple core, through the use of prefixes, suffixes, and vowel alternations.

Philosophical Journey

The trajectory of the word πόρος reflects the evolution of Greek thought from tangible concepts of geography and movement to abstract notions of economics and philosophy:

8th-6th C. BCE
Homeric Era
In the Homeric epics, πόρος is primarily used with the literal meaning of "passage" or "strait," referring to points where one can cross seas or rivers.
5th C. BCE
Classical Athens (Thucydides)
Thucydides employs πόρος to describe strategic passages and routes, emphasizing their importance in warfare and troop movements.
5th-4th C. BCE
Classical Athens (Plato, Xenophon)
Plato develops the philosophical concept of πόρος as "resourcefulness" and "means" for finding solutions. Xenophon uses it extensively for "economic resources" and "means of livelihood."
4th-2nd C. BCE
Hellenistic Period
The word retains the meanings of "means" and "resource" (economic), while also beginning to be used in more technical contexts, such as architecture and engineering, for channels or conduits.
1st C. BCE - 1st C. CE
Koine Greek
In Koine Greek, πόρος continues to be used, though its frequency might be less compared to other words for "way" (e.g., ὁδός). The meanings of "means" and "source" remain stable.
2nd C. CE and beyond
Late Antiquity & Byzantium
In medical and scientific texts, πόρος begins to acquire the meaning of "pore" as a small opening or channel (e.g., pores of the skin), a specialized usage that persists to this day.

In Ancient Texts

Three characteristic passages highlight the multiple uses of πόρος in ancient Greek literature:

«πῶς οὖν ἡ πόλις ἡμῖν ἀρκέσει τούτων πάντων πέρι; ... ἀλλὰ τίς ὁ πόρος;»
How then will the city suffice for all these things? ... But what is the means?
Plato, Republic 370c
«δοκεῖ δέ μοι καὶ οἰκονομίας πέρι καὶ πόρων, οἵτινες ἂν εἶεν ἱκανοὶ πρὸς τὸ ζῆν, οὐκ ἀγνοεῖν.»
It seems to me that concerning household management and resources, what would be sufficient for living, he was not ignorant.
Xenophon, Oeconomicus 1.1
«καὶ οἱ Ἀθηναῖοι ἐκ τῆς Λακωνικῆς ἐς τὴν Ἀττικὴν ἐσέβαλον, καὶ τὸν πόρον τὸν διὰ τῆς Σκιρωνίδος ὁδοῦ ἐτείχισαν.»
And the Athenians invaded Attica from Laconia, and fortified the passage through the Scironian Way.
Thucydides, Histories 7.28.2
