I own about twenty books on the Enneagram, and, along with The Wisdom of the Enneagram by Riso and Hudson, this is one that I regularly turn to, and give to others.
Once we have a working knowledge of the types, what can we DO with our understanding? We live at a time in which all of us are, in the words of adult development researcher Robert Kegan, "over our heads" -- our development has not caught up to the complex demands of the lives that we find ourselves in -- both personally and globally. For each of us to move toward the stabilization of higher stages of development, we must know and know well "what works" and "what doesn't work" for each personality type. This is what Bartlett offers, as described by those who identify as the types themselves.
Thank you, Carolyn! And please find a bigger publisher so that more of us can have access to your book!
