The inability of our species to even understand what it is that I'm saying..
Much less believe it..
They can't even grasp it.
It's like trying to talk to a dog or a monkey or a cage full of monkeys and gorillas and apes and orangutans and chimpanzees..
Saying that caffeine and alcohol and sugar and wheat and milk and juice and honey are the cause of our minds and our creations and societies and war and culture and civilizations dating back tens of thousands of years and we don't know it.
Our minds can't grasp it.
