That has been the perennial state and condition of not simply black people in America, but all self-conscious human beings who are sensitive to the forms of evil around them. We can be prisoners of hope even as we call optimism into question.
This is really powerful to me. I often feel myself clinging to hope while having a negative outlook on the things happening in the world around me. This puts into words some of the mixed feelings I have experienced when hoping for a better world. It reminds me of the saying: "hope for the best, expect for the worst."
