Dave's Enneagram is intended as a centralized resource for studying and exploring the many different interpretations and examples of the Enneagram personality types.
There really is no single authority on the nine types but many different interpretations and applications as presented through various schools, authors, and teachers.
In Their Own Words
A deeper understanding of each Enneagram type comes from hearing directly from people as they describe their internal experience of living from a given type.
Knowing the types of famous people offers an opportunity to learn about the types through the lives and works of famous people.
