Culture is the word he uses most often; though sometimes he uses the word civilization.
He refers to "Takers" and "Leavers". Basically, we are living in an age of Takers. There is no allowance for Leavers. So, we are headed towards our own destruction. Simple enough right?
He has an interesting take on the bible as well. According to what I have read, he believes the bible was actually originally a "leaver" story which was adapted and stolen by the 'takers'.
Anyways, I don't want to derail.
This thread just made me think of his writings.
