The enneagram is a symbol first brought to the West by G. I. Gurdjieff. In the last quarter of the twentieth century, this ancient symbol was arrogated by a populist movement to create an "enneagram industry" that has nothing to do with its true use or with the Fourth Way teaching.
This brief outline attempts to survey what is already known about its construction, and to introduce a new viewpoint that can expand our appreciation of this symbol. http://gate.cruzio.com/~e0yes/properties/
