Humanity’s common nature, beyond the last few hundred years, is actually one of mutual aid and cooperation. I’d encourage you to look into the various Peoples Histories of the various parts of the world. It is increasingly clear the more data is gathered that the current system of elevating greed, avarice, selfishness etc, is a historical outlier on a history that stretches back hundreds of thousands of years of people collectively cooperating.
Now you’re asserting ascribing more and more to me. I’ve read plenty of books, we could go through some we’ve read if you really want to. Have you read Graeber and Wengrow’s “Dawn of Everything: A New History of Humanity”? How about Paulo Freire’s “Pedagogy of the Oppressed”? They’re pretty popular books, I wouldn’t be surprised if you have, but if not I’d recommend them. Do you have any recommendations for me?
