"The life-history of the earth must in the last instance be a history of a really very relentless warfare. Neither his fellows, nor his gods, nor his passions will leave a man alone. In virtue of these allies and enemies, he holds his precarious dominion, he possesses his fleeting significance; and it is this relation in all its manifestations, great and little, superficial or profound, and this relation alone, that is commented upon, interpreted, demonstrated by the art of the novelist in the only possible way in which the task can be performed: by the independent creation of circumstance and character, achieved against all the difficulties of expression, in an imaginative effort finding its inspiration from the reality of forms and sensations. That a sacrifice must be made, that something has to be given up, is the truth engraved in the innermost recesses of the fair temple built for our edification by the masters of fiction. There is no other secret behind the curtain."
