Because, though these gradations of light are indeed, as an object dies in distance, the only things it can retain, yet as it lives its active life near us, those very gradations can only be seen properly by the effect they have on its character. You can only show how the light affects the object, by knowing thoroughly what the object is; and noble mystery differs from ignoble, in being a veil thrown between us and something definite, known, and substantial; but the ignoble mystery is a veil cast before chaos, the studious concealment of Nothing.
§ 11. There is even a way in which the very definiteness of Turner's knowledge adds to the mystery of his pictures. In the course of the first volume I had several times occasion to insist on the singular importance of cast shadows, and the chances of their sometimes gaining supremacy in visibility over even the things that cast them. Now a cast shadow is a much more curious thing than we usually suppose. The strange shapes it gets into—the manner in which it stumbles over everything that comes in its way, and frets itself into all manner of fantastic schism, taking neither the shape of the thing that casts it, nor of that it is cast upon, but an extraordinary, stretched, flattened, fractured, ill-jointed anatomy of its own—cannot be imagined until one is actually engaged in shadow-hunting. If any of these wayward umbræ are faithfully remembered and set down by the painter, they nearly always have an unaccountable look, quite different from anything one would have invented or philosophically conjectured for a shadow; and it constantly happens, in Turner's distances, that such strange pieces of broken shade, accurately remembered, or accurately invented, as the case may be, cause a condition of unintelligibility, quaint and embarrassing almost in exact proportion to the amount of truth it contains.
§ 12. I believe the reader must now sufficiently perceive that the right of being obscure is not one to be lightly claimed; it can only be founded on long effort to be intelligible, and on the present power of being intelligible to the exact degree which the nature of the thing admits. Nor shall we, I hope, any more have difficulty in understanding how the noble mystery and the ignoble, though direct opposites, are yet continually mistaken for each other—the last aping the first; and the most wretched artists taking pride in work which is simply slurred, slovenly, ignorant, empty, and insolent, as if it were nobly mysterious (just as a drunkard who cannot articulate supposes himself oracular); whereas the noble art-mystery, as all noble language-mystery, is reached only by intense labor. Striving to speak with uttermost truth of expression, weighing word against word, and wasting none, the great speaker, or writer, toils first into perfect intelligibleness, then, as he reaches to higher subject, and still more concentrated and wonderful utterance, he becomes ambiguous—as Dante is ambiguous,—half a dozen different meanings lightening out in separate rays from every word, and, here and there, giving rise to much contention of critics as to what the intended meaning actually was. But it is no drunkard's babble for all that, and the men who think it so, at the third hour of the day, do not highly honor themselves in the thought.
§ 13. And now observe how perfectly the conclusions arrived at here consist with those of the third chapter, and how easily we may understand the meaning of that vast weight of authority which we found at first ranged against the clouds, and strong in arms on the side of intelligibility. Nearly all great men must, for the reasons above given, be intelligible. Even, if they are to be the greatest, still they must struggle through intelligibility to obscurity; if of the second class, then the best thing they can do, all their lives through, is to be intelligible. Therefore the enormous majority of all good and true men will be clear men; and the drunkards, sophists, and sensualists will, for the most part, sink back into the fog-bank, and remain wrapt in darkness, unintelligibility, and futility. Yet, here and there, once in a couple of centuries, one man will rise past clearness, and become dark with excess of light.
§ 14. "Well, then, you mean to say that the tendency of this age to general cloudiness, as opposed to the old religious clearness of painting, is one of degradation; but that Turner is this one man who has risen past clearness?"
Yes. With some modifications of the saying, I mean that; but those modifications will take us a little time to express accurately.
For, first, it will not do to condemn every minor painter utterly, the moment we see he is foggy. Copley Fielding, for instance, was a minor painter; but his love of obscurity in rain clouds, and dew-mist on downs, was genuine love, full of sweetness and happy aspiration; and, in this way, a little of the light of the higher mystery is often caught by the simplest men when they keep their hearts open.
§ 15. Neither will it be right to set down every painter for a great man, the moment we find he is clear; for there is a hard and vulgar intelligibility of nothingness, just as there is an ambiguity of nothingness. And as often, in conversation, a man who speaks but badly and indistinctly has, nevertheless, got much to say; and a man who speaks boldly and plainly may yet say what is little worth hearing; so, in painting, there are men who can express themselves but blunderingly, and yet have much in them to express; and there are others who talk with great precision, whose works are yet very impertinent and untrustworthy assertions. Sir Joshua Reynolds is full of fogginess and shortcomings as compared with either of the Caraccis; but yet one Sir Joshua is worth all the Caraccis in Europe; and so, in our modern water-color societies, there are many men who define clearly enough, all whose works, put together, are not worth a careless blot by Cox or Barrett.
§ 16. Let me give one illustration more, which will be also of some historical usefulness in marking the relations of the clear and obscure schools.
We have seen, in our investigation of Greek landscape, Homer's intense love of the aspen poplar. For once, in honor of Homer and the Greeks, I will take an aspen for the subject of comparison, and glance at the different modes in which it would have been, or was, represented from the earliest to the present stage of landscape art.
