A corollary of this is the impossibility of _translations_, in so far as they pretend to effect the transference of one expression into another, like a liquid poured from a vase of a certain shape into a vase of another shape. We can elaborate logically what we have already elaborated in aesthetic form only; but we cannot reduce that which has already possessed its aesthetic form to another form also aesthetic. In truth, every translation either diminishes and spoils; or it creates a new expression, by putting the former back into the crucible and mixing it with other impressions belonging to the pretended translator. In the former case, the expression always remains one, that of the original, the translation being more or less deficient, that is to say, not properly expression: in the other case, there would certainly be two expressions, but with two different contents. "Ugly faithful ones or faithless beauties" is a proverb that well expresses the dilemma with which every translator is faced. In aesthetic translations, such as those which are word for word or interlinear, or paraphrastic translations, are to be looked upon as simple commentaries on the original. [Sidenote] _Critique of rhetorical categories._ The division of expressions into various classes is known in literature by the name of theory of _ornament_ or of _rhetorical categories_. But similar attempts at classification in the other forms of art are not wanting: suffice it to mention the _realistic and symbolic forms_, spoken of in painting and sculpture.
