Representational Systems is described as NLPs second model. (7, p. 164) It was discovered by noticing that the predicates (verbs, adverbs, and adjectives) that people used to describe their experience could be categorized by sensory system, and realizing that they were literal descriptions of the speakers experience. Although that was a very important foundation for many of the distinctions and processes in the field, that too, is an application of an existing linguistic model. The description of the discovery of representational systems (7, pp.164-172) was again not an example of modeling according to St. Clair and Grinders own description.
To summarize, none of the first three fundamental models in NLP described by St. Clair and Grinder satisfy their own criteria for NLP modeling, a major contradiction and incongruence.
