This weight of verifiable place-event-phenomenon-behavior makes the reader forget that he is reading a pure invention, a history that never took place anywhere but in that unlocalizable region, the author's mind. In fact, while we read a novel, we are insane--bonkers. We believe in the existence of people who aren't there, we hear their voices, we watch the battle of Borodino with them, we may even become Napoleon. Sanity returns (in most cases) when the book is closed.
