The trick is to call oneself a slave without in reality being servile. To be the undisputed master without being seen to be so. Like an invisible octopus, to be everywhere and nowhere simultaneously.
Can this be done? Hitler showed us how to do this years ago. Propaganda, mate, that's the way to go.
Watchtower literature, which is the propagandizing instrument used by the "slave," is virtually unintelligible to the average, objective, reader. This is particularly so when one is unacquainted with the semantic distinctivenesss that is so deliberately strewn throughout the pages of such writings.
A skillful blend of the truthful and the extravagant, its balance is weighted in favour of the Watchtower leadership. It is never biblical exposition that establishes the leadership credentials of the "slave" but rather an eccentric interpretation of a little known verse of text. This, coupled with disingenuous argumentation and monotonous and repetetitive temporizing, creates the perfect atmosphere in which to entrench such otherwise unacceptable beliefs.
And the rank and file must really love it, else they would have revolted years ago, when the first examples of Watchtower duplicity became apparent. In fact the literature is intentionally designed, not to enlighten, but to obfuscate, with such literary devises as innovative improvisation and creative dogmatism.
Being soporific, especially on a warm Sunday afternoon, this literature creates a comfortable sense of repose without actually demanding too much intellectual exertion. The polished cordiality, and the feigned interest this "slave" supposedly shows for the fellowship, in fact solicits an attitudinal response where attendance at the interminable meetings becomes required.
Thus, if the "slave" has usurped an authority that is not his to possess in the first place, it has been accomlplished with the passive connivance of the rank and file.
