Why Hén.com is the correct form
ἕν
The name in its original Greek form. Hén (ἕν) is attested as unity, the one, oneness — “Greek neuter of εἷς, "one"; philosophically "The One" in Neoplatonism.”. Its acute accents carry the full phonetic and orthographic weight of the source tradition.
hen
Reduced to plain hen, the name loses everything that made it specific: acute accents. What remains is an ASCII string that machines can parse but that no longer speaks with its original voice.

How Hén was spoken
Unity, First Principle, and Indivisibility
Hén is the Greek neuter of εἷς, 'one'. In everyday speech it is simply the number; in philosophy it became one of the most powerful words in the Western tradition. For Parmenides, Plato, and the Neoplatonists, τὸ ἕν names the ultimate source from which all multiplicity flows.
The indivisible whole that precedes every plurality and every distinction.
In Plato, the One beyond being is identified with the Form of the Good, source of all knowability.
For Plotinus, τὸ ἕν is the first hypostasis, absolutely simple and unknowable, from which Mind and Soul proceed.
What is truly one cannot be divided without ceasing to be itself; it is the root of identity.
Stories of Hén
Hén has no myths in the usual sense, because it is not a person but a principle. Yet its philosophical biography is one of the great narratives of ancient thought.
In his poem On Nature, Parmenides argues that what genuinely is must be one, unchanging, and indivisible. Plurality, change, and becoming are illusions of mortal opinion. The way of truth leads to a single, continuous reality.
In the Republic, Plato places the Form of the Good beyond being, the source that makes the other forms intelligible. Though Plato does not consistently call it ἕν, later Platonists identified the Good with the One, the simple first principle of all things.
Plotinus, the founder of Neoplatonism, made τὸ ἕν the first of his three hypostases. It is absolutely simple, beyond being, intellect, and speech. From it proceeds Nous (Intellect), and from Nous proceeds Soul, and from Soul proceeds the material world.
Names are not merely labels; they are compressed worlds. Hén carries within it a Greek understanding of unity as the first principle of being. Unicode restoration returns that world to readable form.
