General Principles (general overview) 1/2

François-René Rideau		

"The Laws of Human Beings must not contradict that which Nature renders impossible to contradict"

The exclusion principle of physical objects
(you can't have at different places the same car) 
The non-exclusion principle of non-physical objects 
(you can share cooking recipe without damaging somebody)

You can kill a human being but not an idea...

Bernard Lang 

Ecology of Ideas
"...des idées, des concepts, et des objets immatériels qui, pour se développer, s'enrichir et s'épanouir, ont besoin de circuler, de s'associer, de se confronter, de se fertiliser les uns les autres."
