This text investigates the structural mechanisms of defense within the human psyche and their role in the development and maintenance of psychopathological states. Robert Brown White utilizes a clinical framework to examine how individuals employ unconscious strategies to manage anxiety and internal conflict. The work synthesizes traditional psychoanalytic theory with clinical observations to provide a systematic overview of how these defense mechanisms manifest in various diagnostic categories. By mapping these internal processes, the author seeks to clarify the relationship between ego defense and symptomatic behavior.

This work serves as a technical resource for students and practitioners seeking a structured understanding of psychodynamic defense mechanisms. The content reflects a traditional clinical approach, emphasizing the diagnostic utility of identifying specific ego defenses in therapeutic settings.
