ΕΝ
The hen (ἕν), the fundamental concept of unity and singularity, stands as a cornerstone of ancient Greek philosophy, from the Presocratics to Neoplatonism. As a numeral, it denotes the beginning and indivisible wholeness, while as a metaphysical principle, it signifies the ultimate source of all existence. Its lexarithmos (55) underscores its simplicity and essence.
REPORT ERRORDefinition
According to the Liddell-Scott-Jones Lexicon, ἕν (the neuter form of εἷς) is primarily the numeral 'one', denoting a unit or singularity. Its usage quickly expanded from mere quantity to deeper philosophical concepts, making it central to ancient Greek thought.
In philosophy, ἕν emerged as the principle of unity, indivisible wholeness, and identity. For Parmenides, the 'One' is the sole reality, eternal, ungenerated, imperishable, and unchangeable, in contrast to the plurality and motion which are mere illusions. This idea profoundly influenced subsequent philosophical inquiry.
In Plato, ἕν is associated with the Idea of the Good and constitutes the supreme principle from which all Forms emanate. In Aristotle, unity is examined across various categories (continuity, wholeness, species, genus), while in Neoplatonism, particularly in Plotinus, the 'One' becomes the transcendent and ineffable source of all existence, from which Nous (Intellect) and Psyche (Soul) emanate. Its significance is not limited to the numerical unit but extends to the cosmic and metaphysical principle that unifies and grounds reality.
Etymology
From the same root, many words emerge that express the concept of unity, conjunction, or uniqueness. The preposition σύν- (from the older ξύν-) is considered cognate, implying coexistence or unification. Furthermore, words such as μονάς (from μόνος, which is related to ἕν) and its derivatives, as well as terms like ἑνότης and ἑνικός, highlight the root's productivity in the Greek language for creating concepts related to wholeness and individuality.
Main Meanings
- The numeral 'one' — The basic meaning, denoting a single unit or quantity. E.g., «ἓν σῶμα» (one body).
- Unity, wholeness — The philosophical concept of indivisible unity, coherence. E.g., «τὸ ἓν καὶ τὰ πολλά» (the one and the many).
- The same, identical — Denotes identity or similarity. E.g., «τὸ ἓν καὶ ταὐτόν» (the one and the same).
- One and only, unique — Emphasis on exclusivity or uniqueness. E.g., «ἓν μόνον» (one alone).
- Complete, entire — Denotes completeness or integrity. E.g., «ἓν ὅλον» (one whole).
- Agreement, concord — In a social or political context, denotes harmony and unanimity. E.g., «εἰς ἓν συμφωνεῖν» (to agree on one thing).
- As an adverb: 'together', 'at once' — Used to denote coexistence or simultaneous action. E.g., «ἅμα ἓν» (all at once).
Word Family
hen- (root of ἕν, meaning 'one, unity')
The root hen- is the primordial source of words expressing the concept of singularity, unity, and wholeness in ancient Greek. From it derive the three forms of the numeral 'one' (εἷς, μία, ἕν), as well as a series of derivatives and compounds that develop the meanings of conjunction, uniqueness, and cohesion. The significance of this root is fundamental in both everyday language and high philosophy, where the 'One' emerges as a supreme principle.
Philosophical Journey
The concept of ἕν traverses the history of Greek thought, evolving from a simple numeral into a supreme metaphysical principle.
