The fundamental thought of the _Art-work of the Future_ is this: The first and most original of the arts was that of dancing; its peculiar essence is rhythm, and this has developed into music; music, consisting of rhythm and tone, has raised (Wagner says ‘condensed’) its phonetic element to speech, and produced the art of poetry; the highest form of poetry is the drama, which for the purpose of stage-construction, and to imitate the natural scene of human action, has associated itself with architecture and painting respectively; finally, sculpture is nothing but the giving permanence to the appearance of the actor in a dead rigid form, while acting is real sculpture in living, flowing movement. Thus all the arts group themselves around the drama, and the latter should unite them naturally. Nevertheless they appear at present in isolation, to the great injury of each and of art in general. This reciprocal estrangement and isolation of the different arts is an unnatural and decadent condition, and the effort of true artists must be to win them back to their natural and necessary conjunction with each other. The mutual penetration and fusion of all arts into a single art will produce the genuine work of art. Hence the work of art of the future is a drama with music and dance, which unrolls itself in a landscape painting, has for a frame a masterly creation of architectural art designed for the poetico-musical end, and is represented by actors who are really sculptors, but who realize their plastic inspirations by means of their own bodily appearance.
In this way Wagner has set forth for himself the evolution of art. His system calls for criticism in every part. The historical filiation of the arts which he attempts to establish is false. If the original reciprocal connections of song, dance and poetry be granted, the development of architecture, painting and sculpture is certainly independent of poetry in its dramatic form. That the theatre employs all the arts is true, but it is one of those truths which are so self-evident that it is generally unnecessary to mention them, and least of all with profound prophetic mien and the grand priestly gestures of one proclaiming surprising revelations. Everyone knows from experience that the stage is in a theatrical building, that it displays painted decorations which represent landscapes or buildings, and that on it there is speaking, singing and acting. Wagner secretly feels that he makes himself ridiculous when he strains himself to expound this trite matter of first experience in the Pythian mode, with an enormous outlay of gush and exaltation ...; hence he exaggerates it to such a degree as to turn it into an absurdity. He not only asseverates that in the drama (more correctly speaking, the opera, or the musical drama, as Wagner prefers to call it) different arts co-operate, but he asserts that it is only through this co-operation that each individual art is advanced to its highest capacity of expression, and that the individual arts must and will surrender their independence as an unnatural error, in order to continue to exist only as collaborators of the musical drama.
