I've been thinking about nets of reference. Reading Graham Harman I've been led to the work of China Mieville, Timothy Morton, Bruno Latour, et alia, and back to thinking about Heidegger, Husserl and the phenomenologists. And, of course, too, at this point, I want to read everything Harman writes.
This has always been so for me. If I like a writer I try to read all of their work and try to follow up on their references, their loves, until I'm spent.
