A rare occurrence, a few months ago, I came across one (re: a dissertation that is both entertaining and for the lay): Neocosmicism: God and the Void (2013) by Ellen Greenham[1].
It seems like it eventually came into fruition as a full-fledged book: After Engulfment: Cosmicism and Neocosmicism in H. P. Lovecraft, Philip K. Dick, Robert A. Heinlein, and Frank Herbert (2022) by Ellen Greenham[2].
