Human Types

The Socratic injunction, "Know Thyself," is the foundation for all work on selfdevelopment. Susan Zannos opens an illumination window on human behavior and temperament in her study of the basic human essence types. These types differ so much from each other, and are so greatly modified by the dominant type of intelligence operating in a particular person, that persistent and prolonged selfobservation is required to verify one's own type, or to recognize others. Recognition of these types and the division between essence and personality is the foundation upon which practical work on oneself begins.
