The War On Human Imagination - David Graeber

"Scholars tend to demand clear and irrefutable evidence for the existence of democratic institutions of any sort in the distant past. It’s striking how they never demand comparably rigorous proof for top-down structures of authority. These latter are usually treated as a default mode of history: the kind of social structures you would simply expect to see in the absence of evidence for anything else." David Graeber (The Dawn of Everything: A New History of Humanity)
