the stages of simulacra

My read (and I think this is just the first chapter of simulation and simulacra) is that the stages are the progression of sociocultural digestion of memes/ideas and how the internal projections of these change relative to the actual phenomena/concepts they channel

edit: it is the first chapter of simulation and simulacra and I think it's about the nature of representation/abstraction itself, not merely the way we humans do it
