Anne Enright, who visits RPI 4/18, writes about the shortcomings of the short story as a literary form in The Guardian:
"I am not sure whether the novel is written for our convenience, but it is probably written for our satisfaction. That is what readers complain about with short stories, that they are not 'satisfying'. They are the cats of literary form; beautiful, but a little too self-contained for some readers' taste. Short stories are, however, satisfying to write, because they are such achieved things. They become themselves even as you write them: they end once they have attained their natural state. "
"Or some of them do. Others keep going. Others discard the first available meaning for a later, more interesting conclusion. In the interests of truth, some writers resist, backpedal, downplay, switch tacks, come back around a different way. Poe's famous unity of impulse is all very well, but if you know what the impulse is already, then it will surely die when you sit down at the desk." More.
