"Stick to the image" (cf. CW 16: 320) has become a golden rule of archetypal psychology's method, and this because the image is the primary psychological datum. Though the image always implies more than it presents, "the depth of the image - its limitless ambiguities ... can only be partly grasped as implications. To expand upon the dream image is also to narrow it - a further reason we wish never to stray too far from the source" (Berry 1974). It must be noted that the "source" is complex: archetypal psychology is complex at the beginning, since the image is a self-limiting multiple relationship of meanings, moods, historical events, qualitative details, and expressive possibilities. As its referent is imaginal, it always retains a virtuality beyond its actuality (Corbin 1977). An image always seems more profound (archetypal), more powerful (potential), and more beautiful (theophanic) than the comprehension of it, hence the feeling, while recording a dream, of seeing through a glass darkly. Hence, too, the driving necessity in the arts, for they provide complicated disciplines that can actualize the complex virtuality of the image. This polysemantic complexity bespeaks a polytheistic psychology of personifications analogous with Jung's theory of complexes as the multiple consciousness at the base of psychic life (CW 8: 388ff.). By starting with a complex datum - the image - archetypal psychology is saved from accounting for psychic life in simplistic terms of elementary mechanisms, primordialities of origins, or numerically limited basic structures. Reductionism is defeated from the start because the mind is poetic to begin with, and consciousness is not a later, secondary elaboration upon a primitive base, but is given with that base in each image.
— James Hillman
Every interpretive move that takes you away from the image — toward meaning, toward cause, toward symbol-as-code — is already a small act of reduction. Hillman is naming a temptation built into the very desire to understand: that the image might yield, if pressed hard enough, something simpler than itself. It never does. What it offers instead is this "virtuality beyond its actuality," Corbin's phrase for what the imaginal retains even after every reading has been exhausted. The dream of the burning house does not contain a message about your mother. It contains a burning house.
The phrase "seeing through a glass darkly" lands harder here than it does in Paul, because Paul uses it to promise eventual clarity. Hillman strips that promise. The darkened glass is not a deficiency in the seer — it is the nature of the image. Complexity is there at the beginning, not added by interpretation or earned through depth of analysis. This is why the arts are not decoration and not therapy: they are the only disciplines rigorous enough to stay inside the complexity without resolving it. To sit with an image until it has yielded everything is not to arrive somewhere. It is to discover that the image was already more than arrival could mean.
