Full context:   In his earlier "topographic model", Freud divided the psyche into three "regions" or "systems": "the Conscious", that which is present to awareness at the surface level of the psyche in any given moment, including information and stimuli from both internal and external sources; "the Preconscious", consisting of material that is merely latent, not present to consciousness but capable of becoming so; and "the Unconscious", consisting of ideas and impulses that are made completely inaccessible to consciousness by the act of repression. By introducing the structural model, Freud was seeking to reduce his reliance on the term "unconscious" in its systematic and topographic sense—as the mental region that is foreign to the ego—by replacing it with the concept of the 'id'." The partition of the psyche outlined in the structural model is thus one that cuts across the topographical model's partition of "conscious vs. unconscious".
