Imagination is not the exclusive appanage of artists, but belongs in varying degrees to all men. It is simply the power of forming images. Supplying the energy of Sense where Sense cannot reach, it brings into distinctness the facts, obscure or occult, which are grouped round an object or an idea, but which are not actually present to Sense. Thus, at the aspect of a windmill, the mind forms images of many characteristic facts relating to it; and the kind of images will depend very much on the general disposition, or particular mood, of the mind affected by the object: the painter, the poet, and the moralist will have different images suggested by the presence of the windmill or its symbol. There are indeed sluggish minds so incapable of self-evolved activity, and so dependent on the immediate suggestions of Sense, as to be almost destitute of the power of forming distinct images beyond the immediate circle of sensuous associations; and these are rightly named unimaginative minds; but in all minds of energetic activity, groups and clusters of images, many of them representing remote relations, spontaneously present themselves in conjunction with objects or their symbols. It should, however, be borne in mind that Imagination can only recall what Sense has previously impressed. No man imagines any detail of which he has not previously had direct or indirect experience. Objects as fictitious as mermaids and hippogriffs are made up from the gatherings of Sense.
"Made up from the gatherings of Sense" is a phrase which may seem to imply some peculiar plastic power such as is claimed exclusively for artists: a power not of simple recollection, but of recollection and recombination. Yet this power belongs also to philosophers. To combine the half of a woman with the half of a fish,—to imagine the union as an existing organism,—is not really a different process from that of combining the experience of a chemical action with an electric action, and seeing that the two are one existing fact. When the poet hears the storm-cloud muttering, and sees the moonlight sleeping on the bank, he transfers his experience of human phenomena to the cloud and the moonlight: he personifies, draws Nature within the circle of emotion, and is called a poet. When the philosopher sees electricity in the storm-cloud, and sees the sunlight stimulating vegetable growth, he transfers his experience of physical phenomena to these objects, and draws within the circle of Law phenomena which hitherto have been unclassified. Obviously the imagination has been as active in the one case as in the other; the DIFFERENTIA lying in the purposes of the two, and in the general constltution of the two minds.
It has been noted that there is less strain on the imagination of the poet; but even his greater freedom is not altogether disengaged from the necessity of verification; his images must have at least subjective truth; if they do not accurately correspond with objective realities, they must correspond with our sense of congruity. No poet is allowed the licence of creating images inconsistent with our conceptions. If he said the moonlight burnt the bank, we should reject the image as untrue, inconsistent with our conceptions of moonlight; whereas the gentle repose of the moonlight on the bank readily associates itself with images of sleep.
The often mooted question, What is Imagination? thus receives a very clear and definite answer. It is the power of forming images; it reinstates, in a visible group, those objects which are invisible, either from absence or from imperfection of our senses. That is its generic character. Its specific character, which marks it off from Memory, and which is derived from the powers of selection and recombination, will be expounded further on. Here I only touch upon its chief characteristic, in order to disengage the term from that mysteriousness which writers have usually assigned to it, thereby rendering philosophic criticism impossible. Thus disengaged it may be used with more certainty in an attempt to estimate the imaginative power of various works.
Hitherto the amount of that power has been too frequently estimated according to the extent of DEPARTURE from ordinary experience in the images selected. Nineteen out of twenty would unhesitatingly declare that a hippogriff was a greater effort of imagination than a well-conceived human character; a Peri than a woman; Puck or Titania than Falstaff or Imogen. A description of Paradise extremely unlike any known garden must, it is thought, necessarily be more imaginative than the description of a quiet rural nook. It may be more imaginative; it may be less so. All depends upon the mind of the poet. To suppose that it must, because of its departure from ordinary experience, is a serious error. The muscular effort required to draw a cheque for a thousand pounds might as reasonably be thought greater than that required for a cheque of five pounds; and much as the one cheque seems to surpass the other in value, the result of presenting both to the bankers may show that the more modest cheque is worth its full five pounds, whereas the other is only so much waste paper. The description of Paradise may be a glittering farrago; the description of the landscape may be full of sweet rural images: the one having a glare of gaslight and Vauxhall splendour; the other having the scent of new-mown hay.
A work is imaginative in virtue of the power of its images over our emotions; not in virtue of any rarity or surprisingness in the images themselves. A Madonna and Child by Fra Angelico is more powerful over our emotions than a Crucifixion by a vulgar artist; a beggar-boy by Murillo is more imaginative than an Assumption by the same painter; but the Assumption by Titian displays far greater imagination than elther. We must guard against the natural tendency to attribute to the artist what is entirely due to accidental conditions. A tropical scene, luxuriant with tangled overgrowth and impressive in the grandeur of its phenomena, may more decisively arrest our attention than an English landscape with its green corn lands and plenteous homesteads. But this superiority of interest is no proof of the artist's superior imagination; and by a spectator familiar with the tropics, greater interest may be felt in the English landscape, because its images may more forcibly arrest his attentlon by their novelty. And were this not so, were the inalienable impressiveness of tropical scenery always to give the poet who described it a superiority in effect, this would not prove the superiority of his imagination. For either he has been familiar with such scenes, and imagines them just as the other poet imagines his English landscape—-by an effort of mental vision, calling up the absent objects; or he has merely read the descriptions of others, and from these makes up his picture. It is the same with his rival, who also recalls and recombines. Foolish critics often betray their ignorance by saying that a painter or a writer "only copies what he has seen, or puts down what he has known." They forget that no man imagines what he has not seen or known, and that it is in the SELECTION OF THE CHARACTERISTIC DETAILS that the artistic power is manifested. Those who suppose that familiarity with scenes or characters enables a painter or a novelist to "copy" them with artistic effect, forget the well-known fact that the vast majority of men are painfully incompetent to avail themselves of this familiarity, and cannot form vivid pictures even to themselves of scenes in which they pass their daily lives; and if they could imagine these, they would need the delicate selective instinct to guide them in the admission and omission of details, as well as in the grouping of the images. Let any one try to "copy" the wife or brother he knows so well,—to make a human image which shall speak and act so as to impress strangers with a belief in its truth,—and he will then see that the much-despised reliance on actual experience is not the mechanical procedure it is believed to be. When Scott drew Saladin and Ceaur de Lion he did not really display more imaginative power than when he drew the Mucklebackits, although the majority of readers would suppose that the one demanded a great effort of imagination, whereas the other formed part of his familiar experiences of Scottish life. The mistake here lies in confounding the sources from which the materials were derived with the plastic power of forming these materials into images. More conscious effort may have been devoted to the collection of the materials in the one case than in the other, but that this has nothing to do with the imaginative power employed may readily be proved by an analysis of the intellectual processes of composition. Scott had often been in fishermen's cottages and heard them talk; from the registered experience of a thousand details relating to the life of the poor, their feelings and their thoughts, he gained that material upon which his imagination could work; in the case of Saladin and Ceaur de Lion he had to gain these principally through books and his general experience of life; and the images he formed—the vision he had of Mucklebackit and Saladin—must be set down to his artistic faculty, not to his experience or erudition.
It has been well said by a very imaginative writer, that "when a poet floats in the empyrean, and only takes a bird's-eye view of the earth, some people accept the mere fact of his soaring for sublimity, and mistake his dim vision of earth for proximity to heaven." And in like manner, when a thinker frees himself from all the trammels of fact, and propounds a "bold hypothesis," people mistake the vagabond erratic flights of guessing for a higher range of philosophic power. In truth, the imagination is most tasked when it has to paint pictures which shall withstand the silent criticism of general experience, and to frame hypotheses which shall withstand the confrontation with facts. I cannot here enter into the interesting question of Realism and Idealism in Art, which must be debated in a future chapter; but I wish to call special attention to the psychological fact, that fairies and demons, remote as they are from experience, are not created by a more vigorous effort of imagination than milk maids and poachers. The intensity of vision in the artist and of vividness in his creations are the sole tests of his imaginative power.
II.
If this brief exposition has carried the reader's assent, he will readily apply the principle, and recognise that an artist produces an effect in virtue of the distinctness with which he sees the objects he represents, seeing them not vaguely as in vanishing apparitions, but steadily, and in their most characteristic relations. To this Vision he adds artistic skill with which to make us see. He may have clear conceptions, yet fail to make them clear to us: in this case he has imagination, but is not an artist. Without clear Vision no skill can avail. Imperfect Vision necessitates imperfect representation; words take the place of ideas.
In Young's "Night Thoughts" there are many examples of the PSEUDO-imaginative, betraying an utter want of steady Vision. Here is one:—
