Graham Harman's "Weird Realism: Lovecraft and Philosophy"

I recently read Graham Harman's new book Weird Realism: Lovecraft and Philosophy, published by Zero Books, and would like to share a few thoughts concerning the book. Let me say first that it is very enjoyable. Lovecraft and phenomenology? Why the heck not! Of course the book represents what seems to be an exceptionally idiosyncratic project, arguing that a position similar to the one Hölderlin fills for Heideggerian phenomenology should be occupied by H. P. Lovecraft for thinkers of Speculative Realism. I am a passionate fan of Lovecraft but even I found the project at first audacious. Being the type of thinker I am, however, I also found this very audacity amusing and intriguing, an affect I suspect Harman intended. There is, in and of itself, a philosophically important performative force in placing Lovecraft beside accepted standard bearers of high art who have become central figures for philosophy such as Hölderlin, Mallarmé or Beckett. What would it be for Lovecraft to occupy a position of world historical importance in the manner that Heidegger thought Hölderlin did?
