Professor Wilcox's essential point is that Job does curse God. From this central idea he develops a new interpretation of the book. He convincingly argues that, by placing emphasis on the God's natural, beautiful, terrifying, and untameable world the book really is an attempt to undo and reform centuries of Judaic (and by implication Christian) theology.This is by far the best analysis I have yet read on this important work. It is probably worth reading just for the explanation of why Job's daughters are given such special names and receive an inheiritance with their brothers. Of course there is much much more.
I would differ with the author only in a few respects. By way of criticism, it might be pointed out that he does not pay close enough attention to the mystical nature of the poems in Job ch. 38 et seq. (Clearly Job is experiencing a direct--hence mystical c.f. Blake and Scholem--encounter with God in chapter 38) Wilcox's reading of these verses tends to be a bit limited.
These marginal points aside, I reiterate my praise.
