Eros is born, the Love which is an eye filled with its vision, a seeing that bears its image with it; Eros taking its name, probably, from the fact that its essential being is due to this horasis, this seeing. Of course Love, as an emotion, will take its name from Love, the Person, since a Real-Being cannot but be prior to what lacks this reality.
— Plotinus
Plotinus is doing something precise here that is easy to miss in the beauty of the sentence: he is collapsing the distinction between the lover and the vision. Eros is not the god who *has* sight — Eros *is* the seeing, constituted entirely by its own beholding. The Greek word he reaches for, *horasis*, carries both the act of looking and the faculty that makes it possible. The eye and the image it bears are not separable; take away the vision and there is no Eros, only an empty name.
What that means for desire is quietly devastating. Plotinus wants to reassure us that there is a Real-Being behind the emotion, that Love-the-Person precedes love-the-longing, that the straining upward has an object that warrants it. But the logic he offers cuts the other way: if Eros just *is* seeing, then the wanting never reaches beyond itself. The image borne inside the eye is not the beloved — it is the structure of longing itself. Every ascent Plotinus then builds on this ground inherits the same ambiguity. The soul climbs toward the One because it sees; but what it carries up the ladder is a vision generated from within, not a window opened onto something waiting above. Desire does not resolve into union. It sustains itself on its own beholding.
