The word, he says, is connected to the word throne and relates therapy to chair... the chair is intimately involved in our image of therapy. The chair suggests reflection, conversation, stillness, interiority, support, and ordinariness.
Hillman argues etymologically that 'therapy' is structurally linked to 'throne' and 'chair,' making the chair an archetypal emblem of the healing relationship and the therapist a figure who elicits numinous projection.
