Go Achebe!

Before I am accused of prescribing a way in which a writer should write, let me say that I do think decency and civilization would insist that the writer take sides with the powerless. Clearly, there's no moral obligation to write in any particular way. But there is a moral obligation, I think, not to ally oneself with power against the powerless. I think an artist, in my definition of that word, would not be someone who takes sides with the emperor against his powerless subjects.
