I’ve been reading a 1987 book by NLP developers John Grinder and Judith DeLozier. It’s called Turtles All the Way Down: Prerequisites to Personal Genius.
In this book, Grinder essentially mirrors my view of personality as a rhetorical construct, although he would call it a linguistic construct.
The book emphasizes the importance of exploring other perceptual positions when in difficult situations. If you are stuck in, say, self position, you won’t get the benefit of seeing things as others see them or as a disinterested observer would. Not surprisingly, since I have been trained in NLP, the Structural Enneagram includes perceptual positions as the key elements of what I call perspectives.
Perspectives are the building blocks of personality in the Structural Enneagram. Over-reliance on one or two perspectives causes people to be stuck in inflexible and often maladaptive personality patterns.
