Psychic Parasitism

The author has a life-long experience coexisting with people with several personality disorders, and states many if not all of them are merely symptoms or a unique condition. 

Such conclusion lead to coincide this theory with that exposed by other authors, in which institutions are managed by people with several disorders, and thus, the entire civilization inherits the traits of disorders. We would live in a madhouse. 

Psychic Parasitism tells how the dysfunction occurs in the microcosmic level, which would be our daily lives, the macro-cosmic level, the institution running the world, and even a still upper level that would be our more intricate worldview of existence.
