Here is how, he says:
For we have to remember what the novel is. Made by the imagination for the imagination, it is an illusion come full circle—a very exclusive thing, for all it seems to include a good deal of the world. It was wholly for the sake of illusion, made by art out of, and in order to show, and to be, some human truth, that the novelist took all he knew with him and made that leap in the dark.
