The more I've learned in my life, the more acutely I've felt my hunger and blindness, and at the same time the closer I've felt to the end of hunger, the end of blindness. At times I've felt myself to be clinging onto the rim--of what I can hardly say without the risk of sounding ridiculous--only to slip and find myself deeper in the hole than ever. And there, in the dark, I find again in myself a form of praise for all that continues to crush my certainty.
