Dan thinks the Knights say NEE so that they will not be confused by those Knights that say PEE. He thinks the catalyst for Heraldry was a inherent need to organize. Dan thinks the human need for orderliness created the language associated with Heraldry (Heraldry built language - language did not build Heraldry). But I would have to disagree. Heraldry was just another economic strategy using the same motivations for a belief in a higher power. The Knights did not say NEE to be different from those that said PEE. The Knights said NEE because their mind had already evolved (in collusion with language skills) to serve Lord NEE. Their differentiation and subsequent organization from the Knights that said PEE was a BY-PRODUCT. Of course, the unintended consequences of paying homage to Lord NEE was superior survival skills. Superior survival skills selected the culture of Lord Nee (and probably Lord PEE) over those clans without this organizational expertise. Heraldry was just another economic strategy overlayed on the brain function already evolved by the ancients. This function used language and the God delusion to motivate the human organism into survival. In the words of the Great Sage Carville; It's the economy stupid! It always has been and it always will be.
(Walks back from offstage to explain where Falasha missed his point.)
My point about heraldry was to provide a counterexample to Falasha's conjecture regarding the source of emblems. It had nothing to do with language per se, other than, perhaps, to allow some Norman French vocabulary to survive in English.
The Knights who say Ni were a joke. They never existed. Neither did Brave Sir Robin, the Castle Anthrax, nor the giant wooden rabbit.
Linguists aren't in agreement as to how language originated. I'd be surprised, however, if any credible linguist thinks theistic religion was the source.
