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 of 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."Children of Dune"
The writing of history is largely a process of diversion. Most historical accounts distract attention from their secret influences behind great events. The few histories that escape this restrictive process vanish into obscurity through obvious processes. Destruction of as many copies as possible, burying the too revealing accounts in ridicule, ignoring them in the centers of education, insuring that they are not quoted elsewhere.
