Linguistic training can help you learn a new way of internal and external expression and with each different language come correspondingly different assumptions and limitations. Often an initiatory experience carries with it the adaptation of a new set of language, and with it a new sense of possible approaches to any given problem. (This is another example of language as technology.)
Let's also differentiate between private language and public language. While language used within a public sphere must necessarily contain mutually agreed-upon definitions, language used internally, or that which is used within a counter-public sphere, need only be defined by the needs of the individual or the subaltern87 group. These language usages are a parallel form of discourse which enable ideas and discussions that are impossible within a public language, either as a result of linguistic constraints or political liabilities inherent in the word definitions. Such subaltern counterpublic spheres of discourse also serve as a similar memetic pool as mastermind groups, although they exist as a result of marginalization by the public sphere rather than as a result of deliberate formation.
In these instances, private language tends toward as objective a description as possible of what is being defined. Both the metamodel of NLP88 as described by John Grinder and Richard Bandler and E-Prime as described by David Bourland, Jr89 are examples of private language used as technology. Public language can be refined to be used as a tool of influence, misdirection, and manipulation. Such a refinement might include binary oppositions and hooks that are both emotive and evocative. NLP's Milton model and various advertising copy can serve as examples, and overloading speech with words like 'should' and 'is' will also build up a reactive pressure in one's audience.
