In short, he is both diabolical (splitting) and symbolical (integrating) in his function. In his diabolical form, he severs connections in the inner world in order to prevent the unbearable from being experienced. In his symbolical form, he makes whole what was previously fragmented and does this by linking up the unconscious world with the ego through the symbol. Provided that the previously traumatized ego is now strong enough to "bear in mind" the full impact of its experience, the Trickster is freed of his diabolical dismembering role and now contributes to individuation and creative living.
— Donald Kalsched
Kalsched is pointing at something that most trauma frameworks quietly sidestep: the same interior figure that protects is the one who dismembers. The dissociation is not a malfunction to be corrected — it was a solution, arrived at by the soul at the moment when experience exceeded what the ego could metabolize. The Trickster cut the connection because the connection would have been unbearable. You cannot simply resent that.
What shifts the Trickster's function is not insight, not therapeutic technique, not even a decision to face what was previously unbearable. It is the ego's actual capacity — not resolved, not promised, but load-bearing enough to hold the weight without fragmenting again. Kalsched's phrase is precise: "bear in mind" means carry it without being annihilated by it. That threshold is real, and it is not under conscious control.
The hope embedded in this passage is not sentimental. The same interior energy that protected through severance becomes, when the conditions genuinely change, the energy of creative living. Individuation does not recruit new materials; it reroutes the ones already operating. The diabolical and the symbolical are not opposites waiting to be reconciled — they are the same movement in different conditions, the soul's organizing logic running in reverse.
