Perhaps we may lead up to this primitive problem with the question: what æsthetic effect results when the intrinsically separate art-powers, the Apollonian and the Dionysian, enter into concurrent actions? Or, in briefer form: how is music related to image and concept?--Schopenhauer, whom Richard Wagner, with especial reference to this point, accredits with an unsurpassable clearness and perspicuity of exposition, expresses himself most copiously on the subject in the following passage which I shall cite here at full length[21] (_Welt als Wille und Vorstellung,_ I. p. 309): "According to all this, we may regard the phenomenal world, or nature, and music as two different expressions of the same thing,[20] which is therefore itself the only medium of the analogy between these two expressions, so that a knowledge of this medium is required in order to understand that analogy. Music, therefore, if regarded as an expression of the world, is in the highest degree a universal language, which is related indeed to the universality of concepts, much as these are related to the particular things. Its universality, however, is by no means the empty universality of abstraction, but of quite a different kind, and is united with thorough and distinct definiteness. In this respect it resembles geometrical figures and numbers, which are the universal forms of all possible objects of experience and applicable to them all _a priori_, and yet are not abstract but perceptiple and thoroughly determinate. All possible efforts, excitements and manifestations of will, all that goes on in the heart of man and that reason includes in the wide, negative concept of feeling, may be expressed by the infinite number of possible melodies, but always in the universality of mere form, without the material, always according to the thing-in-itself, not the phenomenon,--of which they reproduce the very soul and essence as it were, without the body. This deep relation which music bears to the true nature of all things also explains the fact that suitable music played to any scene, action, event, or surrounding seems to disclose to us its most secret meaning, and appears as the most accurate and distinct commentary upon it; as also the fact that whoever gives himself up entirely to the impression of a symphony seems to see all the possible events of life and the world take place in himself: nevertheless upon reflection he can find no likeness between the music and the things that passed before his mind. For, as we have said, music is distinguished from all the other arts by the fact that it is not a copy of the phenomenon, or, more accurately, the adequate objectivity of the will, but the direct copy of the will itself, and therefore represents the metaphysical of everything physical in the world, and the thing-in-itself of every phenomenon. We might, therefore, just as well call the world embodied music as embodied will: and this is the
