Benedict Anderson
I just learned from L. that Benedict Anderson, the author of Imagined Communities died two days ago.
I read Imagined Communities for a Southeast Asian Studies class my freshman year in college, while I was deep in the throes of identity politics and learning postcolonial thought.
It was instrumental in my better understanding of the homeland of my parents, the Philippines. And it has been critical in the way I parse the media when they discuss our imperial adventures in far-away lands.
It has also been influential in the way I think about worldbuilding in fantasy and science fiction.
