The density and dimensionality of elements located within psychic space are important but neglected participants in the structure of the mind, and the dynamics of it’s participants. The players that interact on the stage of the mind are not the only elements operative within the psyche. The spaces they occupy and the dimensions they have attained are significant as well. A space is necessary as a locale for elements as well as a separate space or room for one’s feelings about it. In metaphorical, as well as actual spacial terms, thoughts can be one-dimensional and concrete. Likewise, feelings can be characterized as flat, and perceptions seen only in primary colors. In similar fashion, a three dimensional experience may be necessary for the qualities of aliveness, humanness and complexity in life. Complexity, for example, is lost when objects can only be two-dimensional, one-sided, and too divergent in space to experience ambivalence, as well as when objects are too close or merged and too convergent in space to experience a sense of separateness. All these states of mind exist in Borderline pathology. This paper will attempt to explore the Borderline dilemma focusing on disturbances in space, time and dimensionality.
