Currently reading: Armand Mattelart, The Invention of Communication. For background, but very interesting. Fills a lot of gaps in my knowledge wrt for instance late 18th & 19th century French philosophy, Saint-Simeonism, the development of traffic, railways, trade, the use of the figures of circulation & network in 18th & 19th century discourse (trade, politics, ‘communication…).
