In all major socializing forces you will find an underlying movement to gain
and maintain power through the use of words. From witch doctor to priest to
bureaucrat it is all the same. A governed populace must be conditioned to
accept power-words as actual things, to confuse the symbolized system with the
tangible universe. In the maintenance of such a power structure, certain
symbols are kept out of the reach of common understanding -- symbols such as
those dealing with economic manipulation or those which define the local
interpretation of sanity. Symbol-secrecy of this form leads to the development
of fragmented sub-languages, each being a signal that its users are
accumulating some form of power. With this insight into a power process, our
Imperial Security Force must be ever alert to the formation of sub-languages.
