Flannery O'connor said this quote

I am often told that the model of balance for the novelist should be Dante, who divided his territory up pretty evenly between hell, purgatory, and paradise. There can be no objection to this, but also there can be no reason to assume that the result of doing it in these times will give us the balanced picture it gave in Dante's. Dante lived in the thirteenth century, when that balance was achieved by the faith of his age. We live now in an age which doubts both fact and value, which is swept this way and that by momentary convictions. Instead of reflecting a balance from the world around him, the novelist now has to achieve one from a felt balance inside himself.
