The book mentions the importance of a “very clean” 3rd position (pp. 234, 255) and “clearly” “clean” and “cleanly” are used repeatedly (pp. 250, 253, 256, 257) but nowhere does it define operationally how to achieve a clean position.
Many years ago Connirae modeled a systematic way to teach clean access to all three positions with her “Aligning Perceptual Positions” process (published in Anchor Point in February 1991). This process uses only the (content-free) submodality of location, and it makes a huge difference in how useful, informative, and resourceful all three positions are, yet the book makes no mention whatsoever of this pattern, which provides an operational definition of clean positions.
The book’s lack of an operational definition for “clean” positions might be excused, but for the fact that it criticizes Eric Robbie for using terms that he does not define:
“c. Robbie introduces and uses terminology without definition thereby removing all possibility of a serious attempt to appreciate whatever insights he is attempting to express—such minimal operational definitions are a prerequisite for opening a professional and interesting dialogue publicly within the field of NLP.” (p. 106)
Besides “clean” positions, this book uses many other terms that are not defined, including, “stalking,” “shunts,” “characterological adjectives.” “automatic movement to privileged states,” (p. 239), “NASA,” “trampoline,” (p. 263) and “mental spaces” (p 296). (“Characterological adjectives” and “mental spaces” may have accepted definitions in linguistics, but most of the book’s readers will not be linguists.)
