Three grades of evil can be discerned in the queer world of verbal transmigration. The first, and lesser one, comprises obvious errors due to ignorance or misguided knowledge. This is mere human frailty and thus excusable. The next step to Hell is taken by the translator who intentionally skips words or passages that he does not bother to understand or that might seem obscure or obscene to vaguely imagined readers; he accepts the blank look that his dictionary gives him without any qualms; or subjects scholarship to primness: he is as ready to know less than the author as he is to think he knows better. The third, and worst, degree of turpitude is reached when a masterpiece is planished and patted into such a shape, vilely beautified in such a fashion as to conform to the notions and prejudices of a given public. This is a crime, to be punished by the stocks as plagiarists were in the shoebuckle days.
