The Milton Model is described as NLPs third model (7, pp. 173-183) and also as the inverse of the meta model.
When we examine the code required to explicate Ericksons verbal patterning, we find precisely the same distinctions that occurred in the meta model... Thus the meta model and the Milton model are often presented as inverses. (7, p. 261)
If the distinctions are precisely the same distinctions that occurred in the meta model, the Milton model is also an application of an existing model, rather than a new model. Since this model already existed, it could not have been elicited by unconscious acquisition, despite St. Clair and Grinders claim to the contrary, and again does not satisfy St. Clair and Grinders own criteria for modeling.
