“Therefore I would ask you to write all kinds of books, hesitating at no subject however trivial or however vast. By hook or by crook, I hope that you will possess yourselves of money enough to travel and to idle, to contemplate the future or the past of the world, to dream over books and loiter at street corners and let the line of thought dip deep into the stream. For I am by no means confining you to fiction. If you would please me - and there are thousands like me - you would write books of travel and adventure, and research and scholarship, and history and biography, and criticism and philosophy and science. By so doing you will certainly profit the art of fiction. For books have a way of influencing each other. Fiction will be much the better for standing cheek by jowl with poetry and philosophy.”
