But indeed the Three compartments mutually support one another, are indispensable to one another. The _Paradiso_, a kind of inarticulate music to me, is the redeeming side of the _Inferno_; the _Inferno_ without it were untrue. All three make up the true Unseen World, as figured in the Christianity of the Middle Ages; a thing forever memorable, forever true in the essence of it, to all men. It was perhaps delineated in no human soul with such depth of veracity as in this of Dante's; a man _sent_ to sing it, to keep it long memorable. Very notable with what brief simplicity he passes out of the every-day reality, into the Invisible one; and in the second or third stanza, we find ourselves in the World of Spirits; and dwell there, as among things palpable, indubitable! To Dante they _were_ so; the real world, as it is called, and its facts, was but the threshold to an infinitely higher Fact of a World. At bottom, the one was as _preternatural_ as the other. Has not each man a soul? He will not only be a spirit, but is one. To the earnest Dante it is all one visible Fact; he believes it, sees it; is the Poet of it in virtue of that. Sincerity, I say again, is the saving merit, now as always. Dante's Hell, Purgatory, Paradise, are a symbol withal, an emblematic representation of his Belief about this Universe:--some Critic in a future age, like those Scandinavian ones the other day, who has ceased altogether to think as Dante did, may find this too all an "Allegory," perhaps an idle Allegory! It is a sublime embodiment, or sublimest, of the soul of Christianity. It expresses, as in huge world-wide architectural emblems, how the Christian Dante felt Good and Evil to be the two polar elements of this Creation, on which it all turns; that these two differ not by preferability of one to the other, but by incompatibility absolute and infinite; that the one is excellent and high as light and Heaven, the other hideous, black as Gehenna and the Pit of Hell! Everlasting Justice, yet with Penitence, with everlasting Pity,--all Christianism, as Dante and the Middle Ages had it, is emblemed here. Emblemed: and yet, as I urged the other day, with what entire truth of purpose; how unconscious of any embleming! Hell, Purgatory, Paradise: these things were not fashioned as emblems; was there, in our Modern European Mind, any thought at all of their being emblems! Were they not indubitable awful facts; the whole heart of man taking them for practically true, all Nature everywhere confirming them? So is it always in these things. Men do not believe an Allegory. The future Critic, whatever his new thought may be, who considers this of Dante to have been all got up as an Allegory, will commit one sore mistake!--Paganism we recognized as a veracious expression of the earnest awe-struck feeling of man towards the Universe; veracious, true once, and still not without worth for us. But mark here the difference of Paganism and Christianism; one great difference.
