AudeSapere,
I've also heard that illustration, not directly from the platform, but I heard JWs talk about what a wonderful illustration it was. What a crock!
Since jw's are discouraged from spending 'useless' time reading non-witness material, most will not know that the concepts are plagerized. Some are likely loopy enough to believe that unscrupulous worldly people have pirated from the org.
This is exactly on point and another reason why the WTBTS does not want their members going to college. The more educated we become about the world around us, the more we understand that there is very little original material actually emanating from the Tower. In fact, as we now know, the precious "doctrinal truths" that we once cherished were ripped of from the Adventist movement that preceded JWism. The WTBTS prefers to have ignorant members. They're more easily manipulated. The ignorant JW just sits back in awe of the "wisdom" being provided by "Jehovah's people." Unfortunately, they don't understand that they just ripped off most of the material from other places.
