Tell me about The Known World.
It’s a novel about slavery, but specifically the few recorded instances of black slave-owners, and it’s a masterful, masterful work, the most complete work of literary imagination in recent American fiction. Edward P Jones could be one of the greatest living American writers. Again it blocks the simple emotional reading that provides redemption, and teaches you that slavery was bad. It shows how dehumanising the whole system was, not only to the slaves, but to everyone involved; it is quite literally soul-emptying. It is of course, again, in some ways like the Holocaust: it was not madness, it was a rational system, an economic system in which all participated in various ways. Even among the slaves there were differences and hierarchies, and degrees of ethical involvement with the issue of slavery. Jones narrates, or manages, dozens of characters. They’re all individually defined, but there’s no central consciousness the way there might be in a straight up psychological novel that you follow as it progresses through some sort of sociological landscape, and so it’s like he’s conducting an orchestra of characters. He shifts from one to the other and has this particular narrative device in which he goes beyond the knowledge of his characters to tell the reader what will happen to them in the years after slavery. The suffering is not simply the physical suffering of individuals; it goes well beyond that. It goes to the heart of the system.
What Jones does is very important, I believe, when we’re talking about war and violence and suffering: not to reduce the understanding to a mere emotional response. Of course the Holocaust is horrifying, of course slavery is horrifying, but if you just see emotional release and redemption then you never understand it and never experience it as a reader.
