The real state of the case is somewhat obscured by our observing that many men of science, and some even eminent as teachers and reporters, display but slender claims to any unusual vigour of imagination. It must be owned that they are often slightly dull; and in matters of Art are not unfrequently blockheads. Nay, they would themselves repel it as a slight if the epithet "imaginative" were applied to them; it would seem to impugn their gravity, to cast doubts upon their accuracy. But such men are the cisterns, not the fountains, of Science. They rely upon the knowledge already organised; they do not bring accessions to the common stock. They are not investigators, but imitators; they are not discoverers--inventors. No man ever made a discovery (he may have stumbled on one) without the exercise of as much imagination as, employed in another direction and in alliance with other faculties, would have gone to the creation of a poem. Every one who has seriously investigated a novel question, who has really interrogated Nature with a view to a distinct answer, will bear me out in saying that it requires intense and sustained effort of imagination. The relations of sequence among the phenomena must be seen; they are hidden; they can only be seen mentally; a thousand suggestions rise before the mind, but they are recognised as old suggestions, or as inadequate to reveal what is sought; the experiments by which the problem may be solved have to be imagined; and to imagine a good experiment is as difficult as to invent a good fable, for we must have distinctly PRESENT--clear mental vision--the known qualities and relations of all the objects, and must see what will be the effect of introducing some new qualifying agent.

If any one thinks this is easy, let him try it: the trial will teach him a lesson respecting the methods of intellectual activity not without its use. Easy enough, indeed, is the ordinary practice of experiment, which is either a mere repet.i.tion or variation of experiments already devised (as ordinary story-tellers re-tell the stories of others), or else a haphazard, blundering way of bringing phenomena together, to see what will happen. To invent is another process. The discoverer and the poet are inventors; and they are so because their mental vision detects the unapparent, unsuspected facts, almost as vividly as ocular vision rests on the apparent and familiar.

It is the special aim of Philosophy to discover and systematise the abstract relations of things; and for this purpose it is forced to allow the things themselves to drop out of sight, fixing attention solely on the quality immediately investigated, to the neglect of all other qualities. Thus the philosopher, having to appreciate the ma.s.s, density, refracting power, or chemical const.i.tution of some object, finds he can best appreciate this by isolating it from every other detail. He abstracts this one quality from the complex bundle of qualities which const.i.tute the object, and he makes this one stand for the whole. This is a necessary simplification. If all the qualities were equally present to his mind, his vision would be perplexed by their multiple suggestions. He may follow out the relations of each in turn, but he cannot follow them out together.

The aim of the poet is very different. He wishes to kindle the emotions by the suggestion of objects themselves; and for this purpose he must present images of the objects rather than of any single quality. It is true that he also must exercise a power of abstraction and selection, tie cannot without confusion present all the details. And it is here that the fine selective instinct of the true artist shows itself, in knowing what details to present and what to omit. Observe this: the abstraction of the philosopher is meant to keep the object itself, with its perturbing suggestions, out of sight, allowing only one quality to fill the field of vision; whereas the abstraction of the poet is meant to bring the object itself into more vivid relief, to make it visible by means of the selected qualities. In other words, the one aims at abstract symbols, the other at picturesque effects. The one can carry on his deductions by the aid of colourless signs, X or Y. The other appeals to the emotions through the symbols which will most vividly express the real objects in their relations to our sensibilities.

Imagination is obviously active in both. From known facts the philosopher infers the facts that are unapparent. He does so by an effort of imagination (hypothesis) which has to be subjected to verification: he makes a mental picture of the unapparent fact, and then sets about to prove that his picture does in some way correspond with the reality. The correctness of his hypothesis and verification must depend on the clearness of his vision. Were all the qualities of things apparent to Sense, there would be no longer any mystery. A glance would be Science. But only some of the facts are visible; and it is because we see little, that we have to imagine much. We see a feather rising in the air, and a quill, from the same bird, sinking to the ground: these contradictory reports of sense lead the mind astray; or perhaps excite a desire to know the reason. We cannot see,--we must imagine,--the unapparent facts. Many mental pictures may be formed, but to form the one which corresponds with the reality requires great sagacity and a very clear vision of known facts. In trying to form this mental picture we remember that when the air is removed the feather fails as rapidly as the quill, and thus we see that the air is the cause of the feather's rising; we mentally see the air pushing under the feather, and see it almost as plainly as if the air were a visible ma.s.s thrusting the feather upwards.

From a mistaken appreciation of the real process this would by few be called an effort of Imagination. On the contrary some "wild hypothesis"

would be lauded as imaginative in proportion as it departed from all suggestion of experience, i.e. real mental vision. To have imagined that the feather rose owing to its "specific lightness," and that the quill fell owing to its "heaviness," would to many appear a more decided effort of the imaginative faculty. Whereas it is no effort of that faculty at all; it is simply naming differently the facts it pretends to explain. To imagine---to form an image--we must have the numerous relations of things present to the mind, and see the objects in their actual order. In this we are of course greatly aided by the ma.s.s of organised experience, which allows us rapidly to estimate the relations of gravity or affinity just as we remember that fire burns and that heated bodies expand. But be the aid great or small, and the result victorious or disastrous, the imaginative process is always the same.

There is a slighter strain on the imagination of the poet, because of his greater freedom. He is not, like the philosopher, limited to the things which are, or were. His vision includes things which might be, and things which never were. The philosopher is not ent.i.tled to a.s.sume that Nature sympathises with man; he must prove the fact to be so if he intend making any use of it ;--we admit no deductions from unproved a.s.sumptions. But the poet is at perfect liberty to a.s.sume this; and having done so, he paints what would be the manifestations of this sympathy. The naturalist who should describe a hippogriff would incur the laughing scorn of Europe; but the poet feigns its existence, and all Europe is delighted when it rises with Astolfo in the air. We never pause to ask the poet whether such an animal exists. He has seen it, and we see it with his eyes. Talking trees do not startle us in Virgil and Tennyson. Puck and t.i.tania, Hamlet and Falstaff, are as true for us as Luther and Napoleon so long as we are in the realm of Art. We grant the poet a free privilege because he will use it only for our pleasure.

In Science pleasure is not an object, and we give no licence.

Philosophy and Art both render the invisible visible by imagination.

Where Sense observes two isolated objects, Imagination discloses two related objects. This relation is the nexus visible. We had not seen it before; it is apparent now. Where we should only see a calamity the poet makes us see a tragedy. Where we could only see a sunrise he enables us to see

"Day like a mighty river flowing in."

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 dest.i.tute of the power of forming distinct images beyond the immediate circle of sensuous a.s.sociations; and these are rightly named unimaginative minds; but in all minds of energetic activity, groups and cl.u.s.ters 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 fict.i.tious 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 uncla.s.sified. 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 a.s.sociates 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 a.s.signed 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 t.i.tania 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 surpa.s.s 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 a.s.sumption by the same painter; but the a.s.sumption by t.i.tian 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 pa.s.s 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 a.n.a.lysis 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 princ.i.p.ally 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 a.s.sent, 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:--

"His hand the good man fixes on the skies, And bids earth roll, nor feels the idle whirl."

"Pause for a moment," remarks a critic, "to realise the image, and the monstrous absurdity of a man's grasping the skies and hanging habitually suspended there, while he contemptuously bids earth roll, warns you that no genuine feeling could have suggested so unnatural a conception." [WESTMINSTER REVIEW, No. cx.x.xi., p. 27]. It is obvious that if Young had imagined the position he a.s.signed to the good man he would have seen its absurdity; instead of imagining, he allowed the vague transient suggestion of half-nascent images to shape themselves in verse.

Now compare with this a pa.s.sage in which imagination is really active.

Wordsworth recalls how--

" In November days When vapours rolling down the valleys made A lonely scene more lonesome; among the woods At noon; and mid the calm of summer nights, When by the margin of the trembling lake Beneath the gloomy hills homeward I went In solitude, such intercourse was mine."

There is nothing very grand or impressive in this pa.s.sage, and therefore it is a better ill.u.s.tration for my purpose. Note how happily the one image, out of a thousand possible images by which November might be characterised, is chosen to call up in us the feeling of the lonely scene; and with what delicate selection the calm of summer nights, the "trembling lake" (an image in an epithet), and the gloomy hills, are brought before us. His boyhood might have furnished him with a hundred different pictures, each as distinct as this; the power is shown in selecting this one--painting it so vividly. He continues:--

"'Twas mine among the fields both day and night And by the waters, all the summer long.

And in the frosty season, when the sun Was set, and, visible for many a mile The cottage windows through the twilight blazed, I heeded not the summons: happy time It was indeed for all of us; for me It was a time of rapture! Clear and loud The village clock tolled six--I wheeled about, Proud and exulting like an untired horse That cares not for his home. All shod with steel We hissed along the polished ice, in games Confederate, imitative of the chase And woodland pleasures--the resounding horn, The pack loud-chiming and the hunted hare."

There is nothing very felicitous in these lines; yet even here the poet, if languid, is never false. As he proceeds the vision brightens, and the verse becomes instinct with life:--

"So through the darkness and the cold we flew And not a voice was idle: with the din Smitten, the precipices rang aloud; THE LEAFLESS TREES AND EVERY ICY CRAG TINKLED LIKE IRON; WHILE THE DISTANT HILLS INTO THE TUMULT SENT AN ALIEN SOUND OF MELANCHOLY, not unnoticed while the stars Eastward were sparkling clear, and in the west The orange sky of evening died away.

"Not seldom from the uproar I retired Into a silent bay, or sportively Glanced sideway, leaving the tumultuous throng, TO CUT ACROSS THE REFLEX OF A STAR; IMAGE THAT FLYING STILL BEFORE ME gleamed Upon the gla.s.sy plain: and oftentime When we had given our bodies to the wind AND ALL THE SHADOWY BANKS ON EITHER SIDE CAME CREEPING THROUGH THE DARKNESS, spinning still The rapid line of motion, then at once Have I reclining back upon my heels Stopped short; yet still the solitary cliffs Wheeled by me--even as if the earth had rolled With visible motion her diurnal round!

Behind me did they stretch in solemn train, Feebler and feebler, and I stood and watched Till all was tranquil as a summer sea."

Every poetical reader will feel delight in the accuracy with which the details are painted, and the marvellous clearness with which the whole scene is imagined, both in its objective and subjective relations, i.e., both in the objects seen and the emotions they suggest.

What the majority of modern verse writers call "imagery," is not the product of imagination, but a restless pursuit of comparison, and a lax use of language. Instead of presenting us with an image of the object, they present us with something which they tell us is like the object---which it rarely is. The thing itself has no clear significance to them, it is only a text for the display of their ingenuity. If, however, we turn from poetasters to poets, we see great accuracy in depicting the things themselves or their suggestions, so that we may be certain the things presented themselves in the field of the poet's vision, and were painted because seen. The images arose with sudden vivacity, or were detained long enough to enable their characters to be seized. It is this power of detention to which I would call particular notice, because a valuable practical lesson may be learned through a proper estimate of it. If clear Vision be indispensable to success in Art, all means of securing that clearness should be sought. Now one means is that of detaining an image long enough before the mind to allow of its being seen in all its characteristics. The explanation Newton gave of his discovery of the great law, points in this direction; it was by always thinking of the subject, by keeping it constantly before his mind, that he finally saw the truth. Artists brood over the chaos of their suggestions, and thus shape them into creations. Try and form a picture in your own mind of your early skating experience. It may be that the scene only comes back upon you in shifting outlines, you recall the general facts, and some few particulars are vivid, but the greater part of the details vanish again before they can a.s.sume decisive shape; they are but half nascent, or die as soon as born: a wave of recollection washes over the mind, but it quickly retires, leaving no trace behind. This is the common experience. Or it may be that the whole scene flashes upon you with peculiar vividness, so that you see, almost as in actual presence, all the leading characteristics of the picture. Wordsworth may have seen his early days in a succession of vivid flashes, or he may have attained to his distinctness of vision by a steadfast continuity of effort, in which what at first was vague became slowly definite as he gazed. It is certain that only a very imaginative mind could have seen such details as he has gathered together in the lines describing how he

"Cut across the reflex of a star; Image that flying still before me gleamed Upon the gla.s.sy plain."

The whole description may have been written with great rapidity, or with anxious and tentative labour: the memories of boyish days may have been kindled with a sudden illumination, or they may have grown slowly into the requisite distinctness, detail after detail emerging from the general obscurity, like the appearing stars at night. But whether the poet felt his way to images and epithets, rapidly or slowly, is unimportant; we have to do only with the result; and the result implies, as an absolute condition, that the images were distinct. Only thus could they serve the purposes of poetry, which must arouse in us memories of similar scenes, and kindle emotions of pleasurable experience.

III.

Having cited an example of bad writing consequent on imperfect Vision, and an example of good writing consequent on accurate Vision, I might consider that enough had been done for the immediate purpose of the present chapter; the many other ill.u.s.trations which the Principle of Vision would require before it could be considered as adequately expounded, I must defer till I come to treat of the application of principles. But before closing this chapter it may be needful to examine some arguments which have a contrary tendency, and imply, or seem to imply, that distinctness of Vision is very far from necessary.

At the outset we must come to an understanding as to this word "image,"

and endeavour to free the word "vision" from all equivoque. If these words were understood literally there would be an obvious absurdity in speaking of an image of a sound, or of seeing an emotion. Yet if by means of symbols the effect of a sound is produced in us, or the psychological state of any human being is rendered intelligible to us, we are said to have images of these things, which the poet has imagined. It is because the eye is the most valued and intellectual of our senses that the majority of metaphors are borrowed from its sensations. Language, after all, is only the use of symbols, and Art also can only affect us through symbols. If a phrase can summon a terror resembling that summoned by the danger which it indicates, a man is said to see the danger. Sometimes a phrase will awaken more vivid images of danger than would be called up by the actual presence of the dangerous object; because the mind will more readily apprehend the symbols of the phrase than interpret the indications of una.s.sisted sense.

Burke in his "Essay on the Sublime and Beautiful," lays down the proposition that distinctness of imagery is often injurious to the effect of art. "It is one thing," he says, "to make an idea clear, another to make it AFFECTING to the imagination. If I make a drawing of a palace or a temple or a landscape, I present a very clear idea of those objects; but then (allowing for the effect of imitation, which is something) my picture can at most affect only as the palace, temple, or landscape would have affected in reality. On the other hand the most lively and spirited verbal description I can give raises a very obscure and imperfect IDEA of such objects; but then it is in my power to raise a stronger EMOTION by the description than I can do by the best painting. This experience constantly evinces. The proper manner of conveying the AFFECTIONS of the mind from one to the other is by words; there is great insufficiency in all other method of communication; and so far is a clearness of imagery, from being absolutely necessary to an influence upon the pa.s.sions, that they may be considerably operated upon without presenting any image at all, by certain sounds adapted to that purpose." If by image is meant only what the eye can see, Burke is undoubtedly right. But this is obviously not our restricted meaning of the word when we speak of poetic imagery; and Burke's error becomes apparent when he proceeds to show that there "are reasons in nature why an obscure idea, when properly conveyed, should be more affecting than the clear." He does not seem to have considered that the idea of an indefinite object can only be properly conveyed by indefinite images; any image of Eternity or Death that pretended to visual distinctness would be false. Having overlooked this, he says, "We do not anywhere meet a more sublime description than this justly celebrated one of Milton, wherein he gives the portrait of Satan with a dignity so suitable to the subject.

"He above the rest In shape and gesture proudly eminent Stood like a tower; his form had not yet lost All her original brightness, nor appeared Less than archangel ruined and the excess Of glory obscured: as when the sun new risen Looks through the horizontal misty air Shorn of his beams; or from behind the moon In dim eclipse disastrous twilight sheds On half the nations; and with fear of change Perplexes monarchs."

"Here is a very n.o.ble picture," adds Burke, "and in what does this poetical picture consist? In images of a tower, an archangel, the sun rising through mists, or an eclipse, the ruin of monarchs, and the revolution of kingdoms." Instead of recognising the imagery here as the source of the power, he says, "The mind is hurried out of itself, [rather a strange result!], by a crowd of great and confused images; which affect because they are crowded and confused For, separate them, and you lose much of the greatness; and join them, and you infallibly lose the clearness." This is altogether a mistake. The images are vivid enough to make us feel the hovering presence of an awe-inspiring figure having the height and firmness of a tower, and the dusky splendour of a ruined archangel. The poet indicates only that amount of concreteness which is necessary for the clearness of the picture,---only the height and firmness of the tower and the brightness of the sun in eclipse.

More concretness would disturb the clearness by calling attention to irrelevant details. To suppose that these images produce the effect because they are crowded and confused (they are crowded and not confused) is to imply that any other images would do equally well, if they were equally crowded. "Separate them, and you lose much of the greatness." Quite true: the image of the tower would want the splendour of the sun. But this much may be said of all descriptions which proceed upon details. And so far from the impressive clearness of the picture vanishing in the crowd of images, it is by these images that the clearness is produced: the details make it impressive, and affect our imagination.

It should be added that Burke came very near a true explanation in the following pa.s.sage:--"It is difficult to conceive how words can move the pa.s.sions which belong to real objects without representing these objects clearly. This is difficult to us because we do not sufficiently distinguish between a clear expression and a strong expression. The former regards the understanding; the latter belongs to the pa.s.sions.

The one describes a thing as it is, the other describes it as it is felt. Now as there is a moving tone of voice, an impa.s.sioned countenance, an agitated gesture, which affect independently of the things about which they are exerted, so there are words and certain dispositions of words which being peculiarly devoted to pa.s.sionate subjects, and always used by those who are under the influence of pa.s.sion, touch and move us more than those which far more clearly and distinctly express the subject-matter." Burke here fails to see that the tones, looks, and gestures are the intelligible symbols of pa.s.sion--the "images' in the true sense just as words are the intelligible symbols of ideas. The subject-matter is as clearly expressed by the one as by the other; for if the description of a Lion be conveyed in the symbols of admiration or of terror, the subject-matter is THEN a Lion pa.s.sionately and not zoologically considered. And this Burke himself was led to admit, for he adds, "We yield to sympathy what we refuse to description. The truth is, all verbal description, merely as naked description, though never so exact, conveys so poor and insufficient an idea of the thing described, that it could scarcely have the smallest eflfect if the speaker did not call in to his aid those modes of speech that work a strong and lively feeling in himself. Then, by the contagion of our pa.s.sions, we catch a fire already kindled in another." This is very true, and it sets clearly forth the fact that naked description, addressed to the calm understanding, has a different subject-matter from description addressed to the feelings, and the symbols by which it is made intelligible must likewise differ. But this in no way impugns the principle of Vision. Intelligible symbols (clear images) are as necessary in the one case as in the other.

IV.

By reducing imagination to the power of forming images, and by insisting that no image can be formed except out of the elements furnished by experience, I do not mean to confound imagination with memory; indeed, the frequent occurrence of great strength of memory with comparative feebleness of imagination, would suffice to warn us against such a conclusion.

Its specific character, that which marks it off from simple memory, is its tendency to selection, abstraction, and recombination. Memory, as pa.s.sive, simply recalls previous experiences of objects and emotions; from these, imagination, as an active faculty, selects the elements which vividly symbolise the objects or emotions, and either by a process of abstraction allows these to do duty for the whole, or else by a process of recombination creates new objects and new relations in which the objects stand to us or to each other (INVENTION), and the result is an image of great vividness, which has perhaps no corresponding reality in the external world.

Minds differ in the vividness with which they recall the elements of previous experience, and mentally see the absent objects; they differ also in the apt.i.tudes for selection, abstraction, and recombination: the fine selective instinct of the artist, which makes him fasten upon the details which will most powerfully affect us, without any disturbance of the harmony of the general impression, does not depend solely upon the vividness of his memory and the clearness with which the objects are seen, but depends also upon very complex and peculiar conditions of sympathy which we call genius. Hence we find one man remembering a mult.i.tude of details, with a memory so vivid that it almost amounts at times to hallucination, yet without any artistic power; and we may find men--Blake was one--with an imagination of unusual activity, who are nevertheless incapable, from deficient sympathy, of seizing upon those symbols which will most affect us. Our native susceptibilities and acquired tastes determine which of the many qualities in an object shall most impress us, and be most clearly recalled. One man remembers the combustible properties of a substance, which to another is memorable for its polarising property; to one man a stream is so much water-power, to another a rendezveus for lovers.

In the close of the last paragraph we came face to face with the great difficulty which constantly arrests speculation on these matters--the existence of special apt.i.tudes vaguely characterised as genius. These are obviously incommunicable. No recipe can be given for genius. No man can be taught how to exercise the power of imagination. But he can be taught how to aid it, and how to a.s.sure himself whether he is using it or not. Having once laid hold of the Principle of Vision as a fundamental principle of Art, he can always thus far apply it, that he can a.s.sure himself whether he does or does not distinctly see the cottage he is describing, the rivulet that is gurgling through his verses, or the character he is painting; he can a.s.sure himself whether he hears the voice of the speakers, and feels that what they say is true to their natures; he can a.s.sure himself whether he sees, as in actual experience, the emotion he is depicting; and he will know that if he does not see these things he must wait until he can, or he will paint them ineffectively. With distinct Vision he will be able to make the best use of his powers of expression; and the most splendid powers of expression will not avail him if his Vision be indistinct. This is true of objects that never were seen by the eye, that never could be seen. It is as true of what are called the highest flights of imagination as of the lowest flights. The mind must SEE the angel or the demon, the hippogriff or centaur, the pixie or the mermaid.
