At this point the fact forces itself on my attention that beside the field of reflection there is another equally broad if not broader area.... This is the realm of Eros. In classical times, when such things were properly understood, Eros was considered a god whose divinity transcended our human limits, and who therefore could neither be comprehended nor represented in any way. I might, as many before me have attempted to do, venture an approach to this daimon, whose range of activity extends from the endless spaces of the heavens to the dark abysses of hell; but I falter before the task of finding the language which might adequately express the incalculable paradoxes of love. Eros is a Rosmogonos, a creator and father-mother of all higher consciousness...; [it] might well be the first condition of all cognition and the quintessence of divinity itself.
— James Hillman
The passage is attributed to Hillman, but the voice is Jung's — this is Jung writing about Eros in "The Psychology of the Transference," and Hillman is quoting him as evidence. Notice what Jung does the moment he encounters Eros: he falters. The thinker who anatomized the unconscious with clinical precision says he cannot find the language. That faltering is not a failure of nerve; it is the most honest thing in the passage. Eros will not hold still inside reflection's frame, and reflection — the very mode by which depth psychology works — is being named here as only half the field.
What Hillman hears in Jung's hesitation is a systematic problem. If Eros is prior to cognition, if it is somehow the condition under which thinking happens at all, then any attempt to grasp it from inside thought will always arrive late. The cosmogonic weight Jung gives it — creator, father-mother, quintessence of divinity — is his way of marking that priority without pretending to explain it. Desire does not emerge from consciousness; consciousness, on this reading, emerges from desire. Which means the longing underneath every question you bring to a text like this one is not the obstacle to understanding. It is the reason anything is understood at all.
