This came to me as a GODSEND (arr, DIVINITY-SENT) as I was getting a little discouraged chugging through one book after another by Heidegger. Mitchell does such a good job of connecting and elucidating MANY of the perplexing ideas found in the late Heidegger, especially those centered around the Fourfold (the round dance, the holy, the aether, the hale/unhale, granting, grace, whiling, etc.), and GOSH this helped me tremendously. Of course, there are things (dare I say that?) I'm still perplexed about, things Mitchell tries to explain but no matter how many times I read the relevant passages the meaning eluded me (withdrawing from me in its unconcealment, as it were), such as how language is a medium, and why there are SO many media (or are they all name the same?), what differentiation and gesture really are, how death shrines nothing, the concept (or relation, should I say?) of groundless bearing, the whole complicated relations among the truth of being, the holy, godhood, and gods, and what the damn "sanctioning" region is. Despite these, though, the book has been IMMENSELY helpful for me in wrapping my head around the dizzying array of concepts (that reifying word again...) and their interrelationships, and I understood enough to be blown away by some of the things Heidegger—according to Mitchell—meant.
Like in essencing where there's no complete arrival, though, or just as we mortals are not-yet mortals, I'll always be ever arriving in understanding Heidegger without ever reaching it—not completely perplexed but never in a complete grasp of him (then he'd cease to be other, without secrets), allowed to be in the between of philosophical journey. I will always be on the way.
