It's a theory I have had for a long time.

I speak or write words that you hear or read and it programs your brain. The more eloquently and/or logically I speak or write programs your brain deeper.

Propaganda attacks the emotional centers of your brain eliciting primal responses that are expressed outwardly. Teaching hits other parts and expands you internally. Poetry hits emotional parts as well but remains within you like water flowing under the bridge between propaganda and teaching.
