So, this paper i STARTED to read by Jason Turner on Ontological Pluralism was from 2009. He mentions a philosophy professor named Kris McDaniel who published a book in 2017 called “The Fragmentation of Being”, about Ontological Pluralism, which I started to read when I paused Jason Turner’s writing and looked up Kris McDaniel’s writing and found his later book.
But it turns out Kris McDaniel didn’t KNOW he was espousing ontological pluralism – just that he had these ideas – UNTIL Jason Turner wrote it in 2009. So, it looks like it’s a small world there.
