Psychization names the process by which instinctual, somatic, or outer-world stimuli are taken up into and modified by the psyche, thereby acquiring psychological form, meaning, and symbolic valence. The term enters depth-psychological discourse primarily through Jung, who employs it in two distinct but related registers. In the first, most technical sense, psychization designates the interference that psychic processes exert upon raw instinctual discharge: the reflex arc is ‘bent back’ (reflexio), and the impulse, instead of being blindly acted out, is drawn into psychic elaboration, generating reflection, symbol, and the specifically human instinct Jung calls the creative drive. In the second, more phenomenological register—developed with equal force by Erich Neumann—psychization describes what primitive consciousness performs upon the external world: objects are experienced as saturated with inner, psychic content, such that the boundary between inside and outside dissolves into symbolic participation. Hillman inherits both valences, reading psychization as the condition of possibility for genuine creativity: every instinct, including the creative one, must be subject to psychic modification before it becomes humanly significant. The term therefore anchors a central depth-psychological claim—that the specifically human emerges precisely at the threshold where biology is taken into soul.
