The writer's job is to see through the lies and layers of falsehood around him. To cut through the noise and cries to get to the heart of the matter. To the key to the situation; the truth of the world. From Brothers Karamazov to Heart of Darkness to Rebecca this has been the novelist's goal.
A writer, especially a novelist, should have one overriding concern: getting to the truth. It's what fiction at its best is about. What really happened? This is the task of the true writer-- maybe his only true task. All else is posing.
