Poetry once raised to its proper place, the arts of sound and form, which render in a more vivid way the subjects which Poetry has suggested, will soon follow. Their sphere, like that of Poetry, will be the celebration of Humanity; an exhaustless field, leaving no cause to regret the chimeras which, in the present empirical condition of these arts, are still considered indispensable. Music in modern times has been limited almost entirely to the expression of individual emotions. Its full power has never been felt in public life, except in the solitary instance of the _Marseillaise_, in which the whole spirit of our great Revolution stands recorded. But in the worship of Humanity, based as it is on Positive education, and animated by the spirit of Poetry, Music, as the most social of the special arts, will aid in the representation of the attributes and destinies of Humanity, and in the glorification of great historical types. Painting and Sculpture will have the same object; they will enable us to realize the conception of Humanity with greater clearness and precision than would be possible for Poetry, even with the aid of Music. The beautiful attempts of the artists of the sixteenth century, men who had very little theological belief, to embody the Christian ideal of Woman, may be regarded as an unconscious prelude to the representation of Humanity, in the form which of all others is most suitable. Under the impulse of these feelings, the sculptor will overcome the technical difficulties of representing figures in groups, and will adopt such subjects by preference. Hitherto this has only been effected in bas-reliefs, works which stand midway between painting and sculpture. There are, however, some splendid exceptions from which we can imagine the scope and grandeur of the latter art, when raised to its true position. Statuesque groups, whether the figures are joined or, as is preferable, separate, will enable the sculptor to undertake many great subjects from which he has been hitherto debarred.
