So this time I read it in small portions and an active pen in my hand. Also a good way! (Last time's unmitigated praise here)
What stuck with me the most on this reread was the concept of cognitive dissonance : "Every man-made order is packed with internal contradictions. Cultures are constantly trying to reconcile these contradictions, and this process fuels change."
For instance, we see equality and individual freedom as fundamental values. "Yet the two values contradict each other. Equality can be ensured only by curtailing the freedoms of those who are better off. Guaranteeing that every individual will be free to do as he wishes inevitably short-changes equality."
You might argue this is more of a philosophy-lesson than the history Harari promises in the title, and I would say it is both and all the better for it.
