Carl Jung talks about biological truth and about the necessity of staying close to your roots.
“A man is not complete when he lives in a world of the statistical truth. He must live in a world of his biological truth. Man has always lived in the myth and we think we are able to be born today and to live in no myth, without history. That is a disease. It’s absolutely abnormal! Because man is not born everyday. He is once born in a specific historical setting with specific historical qualities and therefore he is only complete when he has a relation to it… to these things. It’s as if you are born without eyes and ears when you are growing up with no connection to the past. From the established method of natural science you need no connection to the past. You can wipe it out. That is a mutilation of the human being.”
