Invisibility in the depth-psychology corpus is not a single concept but a constellation of interrelated meanings that range across ontology, epistemology, and practical psychology. At its most fundamental, the term marks the boundary between what consciousness can apprehend and what exceeds or eludes it — yet the corpus refuses any simple equation of the invisible with the merely unconscious. Hillman is the most sustained voice on the subject, arguing that the invisible is not simply below or behind the visible but may surpass it: the daimon, the ancestor, the angel, the acorn are invisible not because they are repressed but because our doctrinal habits of perception have blinded us to them. Von Franz reads the fairy-tale motif of the cloak of invisibility as signifying the elimination of egocentricity in pursuit of a transpersonal goal. Corbin, drawing on Sufi cosmology, insists that the invisible must be stratified: there is both an infraconsciousness below and a supraconsciousness above the plane of ordinary awareness, and the invisibility of an object can signal either a lack of light or an excess of light the eye cannot bear. Giegerich approaches invisibility as an intrinsic quality of the soul itself — invisible, intangible, and, under positivistic knowing, unspeakable. Vernant maps the problem onto Greek image-making: how to inscribe absence in presence, to render visible those powers that belong to the other world. The term thus marks a structural tension between phenomenal appearance and transphenomenal depth that runs across nearly all depth-psychological inquiry.
