I read two thirds of "Changer de société, refaire de la sociologie" and it was a hard read, most of what he wrote didn't make sense or wasn't well illustrated. It didn't seem like he wanted me to understand his points, nor take me on a laborious journey where my way of seeing things would be transformed
I feel like that’s a fairly dense, technical point of entry for his work, since he’s explicitly trying to set up an alternative theoretical framework for his brand of sociological/anthropological philosophy. Did you read Lab Life?
I have to admit, I have no idea how I came across this book from Latour, I guess I just liked the title. But the one you quoted looks interesting beyond just the title
