Many writers lay very great stress upon some definite moral purpose, at which they profess to aim their works. Not to be deficient in this particular, the author has provided himself with a moral, — the truth, namely, that the wrong-doing of one generation lives into the successive ones, and, divesting itself of every temporary advantage, becomes a pure and uncontrollable mischief; and he would feel it a singular gratification if this romance might effectually convince mankind — or, indeed, any one man — of the folly of tumbling down an avalanche of ill-gotten gold, or real estate, on the heads of an unfortunate posterity, thereby to maim and crush them, until the accumulated mass shall be scattered abroad in its original atoms. In good faith, however, he is not sufficiently imaginative to flatter himself with the slightest hope of this kind. When romances do really teach anything, or produce any effective operation, it is usually through a far more subtile process than the ostensible one. The author has considered it hardly worth his while, therefore, relentlessly to impale the story with its moral as with an iron rod, — or, rather, as by sticking a pin through a butterfly, — thus at once depriving it of life, and causing it to stiffen in an ungainly and unnatural attitude. A high truth, indeed, fairly, finely, and skilfully wrought out, brightening at every step, and crowning the final development of a work of fiction, may add an artistic glory, but is never any truer, and seldom any more evident, at the last page than at the first.
—Nathaniel Hawthorne, The House of the Seven Gables, Preface (1851)
