In this respect one art may need the consciousness and cognition of such matter more than others. Music, for instance, which concerns itself only with the undefined movement of the inward spiritual nature, and deals with musical sounds as, so to speak, feeling without thought, needs little or no spiritual content to be present in consciousness. It is for this reason that musical talent generally announces itself in very early youth, while the head is still empty and the heart has been but little moved, and is capable of attaining to a very considerable height in early years, before mind and life have experience of themselves. And again, as a matter of fact we often enough see very great expertness in musical composition, as also in execution, subsist along with remarkable barrenness of mind and character. The reverse is the case with poetry. In poetry all depends on the representation,--which must be full of matter and thought--of man, of his profounder interests, and of the powers that move him; and therefore mind and heart themselves must be richly and profoundly educated by life, experience, and reflection, before genius can bring to pass anything mature, substantial, and self-complete. Goethe's and Schiller's first productions are of an immaturity, and even of a rudeness and barbarism, that are absolutely terrifying. This phenomenon, that the greater part of those attempts display a predominant mass of thoroughly prosaic and in part of frigid and commonplace elements, furnishes the chief objection to the common opinion, that inspiration is inseparable from youth and youthful fire. Those two men of genius, it may be said, were the first to give our nation works of true poetry, and yet it was only their mature manhood[49] that presented us with creations profound, substantial, and the outcome of genuine inspiration, while no less thoroughly perfect in form. Thus, too, it was not till his old age that Homer devised and uttered his immortal songs.
