“We must grant the artist his subject, his idea, what the French call his donnée; our criticism is applied only to what he makes of it. Naturally I do not mean that we are bound to like it or find it interesting: in case we do not our course is perfectly simple–to let it alone. We may believe that of a certain idea even the most sincere novelist can make nothing at all, and the event may perfectly justify our belief; but the failure will have been a failure to execute, and it is in the execution that the fatal weakness is recorded.”
Henry James, “The Art of Fiction”
