You could make a good case that the history of social life is about the history of the technology of memory. That social order and control, structure of governance, social cohesion in states or organizations larger than face-to-face society depends on the nature of the technology of memory - both how it works and what it remembers. In short, what societies value is what they memorize, and how they memorize it, and who has access to its memorized form determines the structure of power that the society represents and acts from.
