For the senses, scorned as they had been in philosophy hitherto, the senses in this philosophy, have _their_ report also,--their full, honest report, to make to us. And the design of this piece, as already stated in the general, required in its execution, not only that these two kinds of suffering, these two grand departments of human need, should be included and distinguished in it, but that they should be brought together in this one man's experience, so that a deliberate comparison can be instituted between them; and the Poet will bid the philosophic king, the living 'subject' himself, report the experiment, and tell us plainly, once for all, whether the science of the physical Arts only, is the science which is wanting to man; or whether arts--scientific arts--that take hold of the moral nature, also, and deal with that not less effectively, can be dispensed with; whether, indeed, man is in any condition to dispense with _the_ Science and _the_ Art which puts him into intelligent and harmonious relations with nature in general. It was necessary to the purpose of the play to exhibit man's dependence on art, by means of his senses _and_ his sensibilities, and his intellectual conditions, and all his frailties and liabilities,-- his dependence on art, based on the knowledge of natural laws, universal laws,--constitutions, which _include_ the human. It was necessary to exhibit the whole misery, the last extreme of that social evil, to which a creature so naturally frail and ignorant is liable, under those coarse, fortuitous, inartistic, unscientific social conglomerations, which ignorant and barbarous ages build, and under the tyranny of those wild, barbaric social evils, which our fine social institutions, notwithstanding the universality of their terms, and the transcendant nature of the forces which they are understood to have at their disposal, for some fatal reason or other, do not yet succeed in reducing. It is, indeed, the whole ground of the Scientific Human Art, which is revealed here by the light of this great passion, and that, in this Poet's opinion, is none other than the ground of the human want, and is as large and various as that. And the careful reader of this play,--the patient searcher of its subtle lore,--the diligent collector of its thick-crowding philosophic points and flashing condensations of discovery, will find that the _need of arts_, is that which is set forth in it, with all the power of its magnificent poetic embodiment, and in the abstract as well,--the need of arts infinitely more noble and effective, more nearly matched with the subtlety of nature, and better able to entangle and subdue its oppositions, than any of which mankind have yet been able to possess themselves, or ever the true intention of nature in the human form can be realized, or anything like a truly Human Constitution, or Common-Weal, is possible.
