Ur-Fascism is essential (you can read it for free here https://www.nybooks.com/articles/1995/06/22/ur-fascism/). The other essays are interesting to read in 2018, especially about the media and the potential of the internet (Eco seems to understand that a free internet was at risk of falling victim to exploitative capital to stay "free", which, lol). Some of the essays felt like they were building to a hook that never came, but this wouldn't be the first time I was too stupid to appreciate something Eco was trying to say.
