"[A] continuum of severity, from a relatively healthy to a very disturbed level of personality structure. This continuum is conventionally, if arbitrarily, divided into healthy, neurotic, and borderline ranges of personality organization, the borderline range extending from the border of neurotic character organization to the border of psychotic conditions." It is important to point out that "borderline" in a psychiatric context, "Borderline Personality Disorder" (DSM) refers to a certain type of borderline, namely a more outgoing, dramatic form, which was originally delimited for research purposes (p.21). The psychodynamic concept is broader and, if you will, more universally human. It stems from a time in our lives when it was actually normal to perceive and interact with the world in this characteristic, often simplistic way, and which remains as a capacity even in adulthood.
