Music is certainly able with the means at its own disposal to express every movement of the will, every feeling; but by the addition of words we receive besides this the objects of these feelings, the motives which occasion them.

Context

“The most direct is that for which music expresses the emotions of the will itself, and the most indirect that of conceptions denoted by words. When the language of the feelings is in question the reason does not willingly sit entirely idle. Music is certainly able with the means at its own disposal to express every movement of the will, every feeling; but by the addition of words we receive besides this the objects of these feelings, the motives which occasion them. The music of an opera, as it is presented in the score, has a completely independent, separate, and, as it were, abstract existence for itself, to which the incidents and persons of the piece are foreign, and which follows its own unchanging rules; therefore it can produce its full effect without the libretto.” source
