We have now exhibited two pictures, and by two painters who may be said to stand at opposite poles. And yet, widely apart as are their apparent stations, they are nevertheless tenants of the same ground, namely, actual nature; the only difference being, that one is the sovereign of the purely physical, the other of the moral and intellectual, while their common medium is the catholic ground of the imagination.

We do not fear either skeptical demur or direct contradiction, when we assert that the imagination is as much the medium of the homely Ostade, as of the refined Raffaelle. For what is that, which has just wrapped us as in a spell when we entered his humble cottage,--which, as we wandered through it, invested the coarsest object with a strange charm? Was it the truth of these objects that we there acknowledged? In part, certainly, but not simply the truth that belongs to their originals; it was the truth of his own individual mind superadded to that of nature, nay, clothed upon besides by his imagination, imbuing it with all the poetic hues which float in the opposite regions of night and day, and which only a poet can mingle and make visible in one pervading atmosphere. To all this our own minds, our own imaginations, respond, and we pronounce it true to both. We have no other rule, and well may the artists of every age and country thank the great Lawgiver that there is no other. The despised feeling which the schools have scouted is yet the mother of that science of which they vainly boast. But of this we may have more to say in another place.

We shall now ascend from the probable to the possible, to that branch of Invention whose proper office is from the known but fragmentary to realize the unknown; in other words, to embody the possible, having its sphere of action in the world of Ideas. To this class, therefore, may properly be assigned the term Ideal.

And here, as being its most important scene, it will be necessary to take a more particular view of the verifying principle, the agent, so to speak, that gives reality to the inward, when outwardly manifested.

Now, whether we call this Human or Poetic Truth, or inward life, it matters not; we know by its effects, (as we have already said, and we now repeat,) that some such principle does exist, and that it acts upon us, and in a way analogous to the operation of that which we call truth and life in the world about us. And that the cause of this analogy is a real affinity between the two powers seems to us confirmed, not only positively by this acknowledged fact, but also negatively by the absence of the effect above mentioned in all those productions of the mind which we pronounce unnatural. It is therefore in effect, or quoad ourselves, both truth and life, addressed, if we may use the expression, to that inscrutable instinct of the imagination which conducts us to the knowledge of all invisible realities.

A distinct apprehension of the reality and of the office of this important principle, we cannot but think, will enable us to ascertain with some degree of precision, at least so far as relates to art, the true limits of the Possible,--the sphere, as premised, of Ideal Invention.

As to what some have called our creative powers, we take it for granted that no correct thinker has ever applied such expressions literally. Strictly speaking, we can make nothing: we can only construct. But how vast a theatre is here laid open to the constructive powers of the finite creature; where the physical eye is permitted to travel for millions and millions of miles, while that of the mind may, swifter than light, follow out the journey, from star to star, till it falls back on itself with the humbling conviction that the measureless journey is then but begun! It is needless to dwell on the immeasurable mass of materials which a world like this may supply to the Artist.

The very thought of its vastness darkens into wonder. Yet how much deeper the wonder, when the created mind looks into itself, and contemplates the power of impressing its thoughts on all things visible; nay, of giving the likeness of life to things inanimate; and, still more marvellous, by the mere combination of words or colors, of evolving into shape its own Idea, till some unknown form, having no type in the actual, is made to seem to us an organized being. When such is the result of any unknown combination, then it is that we achieve the Possible. And here the Realizing Principle may strictly be said to prove itself.

That such an effect should follow a cause which we know to be purely imaginary, supposes, as we have said, something in ourselves which holds, of necessity, a predetermined relation to every object either outwardly existing or projected from the mind, which we thus recognize as true. If so, then the Possible and the Ideal are convertible terms; having their existence, ab initio, in the nature of the mind. The soundness of this inference is also supported negatively, as just observed, by the opposite result, as in the case of those fantastic combinations, which we sometimes meet with both in Poetry and Painting, and which we do not hesitate to pronounce unnatural, that is, false.

And here we would not be understood as implying the preëxistence of all possible forms, as so many patterns, but only of that constructive Power which imparts its own Truth to the unseen real, and, under certain conditions, reflects the image or semblance of its truth on all things imagined; and which must be assumed in order to account for the phenomena presented in the frequent coincident effect between the real and the feigned. Nor does the absence of consciousness in particular individuals, as to this Power in themselves, fairly affect its universality, at least potentially: since by the same rule there would be equal ground for denying the existence of any faculty of the mind which is of slow or gradual developement; all that we may reasonably infer in such cases is, that the whole mind is not yet revealed to itself. In some of the greatest artists, the inventive powers have been of late developement; as in Claude, and the sculptor Falconet. And can any one believe that, while the latter was hewing his master's marble, and the former making pastry, either of them was conscious of the sublime Ideas which afterwards took form for the admiration of the world? When Raffaelle, then a youth, was selected to execute the noble works which now live on the walls of the Vatican, "he had done little or nothing," says Reynolds, "to justify so high a trust." Nor could he have been certain, from what he knew of himself, that he was equal to the task. He could only hope to succeed; and his hope was no doubt founded on his experience of the progressive developement of his mind in former efforts; rationally concluding, that the originally seeming blank from which had arisen so many admirable forms was still teeming with others, that only wanted the occasion, or excitement, to come forth at his bidding.
