The Great Forgetting refers to the wealth of knowledge that our culture lost when we adopted our new civilized lifestyle. The knowledge that allowed indigenous cultures to survive, the knowledge that we had once also been tribal and the understanding that we were but one mere culture of thousands. All of this disappeared in a few short generations.
The Great Forgetting accounts for an enormous cultural collapse as once tribal people found themselves in a new and strange mass centralized society. New beliefs, new ways of life rushed into this cultural vacuum to fill the void. But without being tested by natural selection over thousands of years this new culture was evolutionarily unstable.
It is only recently that the Great Forgetting has been exposed. Understanding it holds the key to making sense of our destructive culture. And remembering what it is that was forgotten holds the key to our future.
