Complete. From “Marginalia.”

THE PURE Imagination chooses, from either beauty or deformity, only the most combinable things hitherto uncombined; the compound, as a general rule, partaking, in character, of beauty, or sublimity, in the ratio of the respective beauty or sublimity of the things combined,—which are themselves still to be considered as atomic,—that is to say, as previous combinations. But as often analogously happens in physical chemistry, so not unfrequently does it occur in this chemistry of the intellect, that the admixture of two elements results in a something that has nothing of the qualities of one of them, or even nothing of the qualities of either…. Thus, the range of Imagination is unlimited. Its materials extend throughout the universe. Even out of deformities it fabricates that Beauty which is at once its sole object and its inevitable test. But, in general, the richness or force of the matters combined; the facility of discovering combinable novelties worth combining; and, especially, the absolute “chemical combination” of the completed mass—are the particulars to be regarded in our estimate of Imagination. It is this thorough harmony of an imaginative work which so often causes it to be undervalued by the thoughtless, through the character of obviousness which is superinduced. We are apt to find ourselves asking why it is that these combinations have never been imagined before.
