Tied Images.—Visual sensations of words do not commonly occur by themselves. They have certain regular companions so closely tied to them as to be only with difficulty disconnected. The chief of these are the auditory image—the sound of the words in the mind’s ear—and the image of articulation—the feel in the lips, mouth, and throat, of what the words would be like to speak.
Auditory images of words are among the most obvious of mental happenings. Any line of verse or prose slowly read, will, for most people, sound mutely in the imagination somewhat as it would if read aloud. But the degree of correspondence between the image-sounds, and the actual sounds that the reader would produce, varies enormously. Many people are able to imagine word-sounds with greater delicacy and discrimination than they can utter them. But the reverse case is also found. What importance then is to be attached to clear, rich and delicate sound imagery in silent reading? How far must people who differ in their capacity to produce such images differ in their total reactions to poems? And what are the advantages of reading aloud? Here we reach one of the practical problems of criticism for which this analysis is required. A discussion is best postponed until the whole analysis has been given. The principal confusion which prevents a clear understanding of the point at issue does, however, concern images and may be dealt with here. It is of great importance in connection with the topic of the following section.
The sensory qualities of images, their vivacity, clearness, fullness of detail and so on, do not bear any constant relation to their effects. Images differing in these respects may have closely similar consequences. Too much importance has always been attached to the sensory qualities of images. What gives an image efficacy is less its vividness as an image than its character as a mental event peculiarly connected with sensation. Lissette way which no one yet knows how to explain, a relict of sensation and our intellectual and emotional response to it depends far more upon its being, through this fact, a representative of a sensation, than upon its sensory resemblance to one. An image may lose almost all its sensory nature to the point of becoming scarcely an image at all, a mere skeleton, and yet represent a sensation quite as adequately as if it were flaring with hallucinatory vividity. In other words, what matters is not the sensory resemblance of an image to the sensation which is its prototype, but some other relation, at present hidden from us in the jungles of neurology. (Cf. Chapter XIV.)
Care then should be taken to avoid the natural tendency to suppose that the more clear and vivid an image the greater will be its efficacy. There are trustworthy people who, according to their accounts, never experience any imagery at all. If certain views commonly expressed about the arts are true, by which vivid imagery is an all-important part of the experience, then these people are incapable of art experiences, a conclusion which is contrary to the facts. The views in question are overlooking the fact that something takes the place of vivid images in these people, and that, provided the image-substitute is efficacious, their lack of mimetic imagery is of no consequence. The efficacy required must, of course, include control over emotional as well as intellectual reactions. Needless perhaps to add that with persons of the image-producing types an increase in delicacy and vivacity in their imagery will probably be accompanied by increased subtlety in effects. Thus it is not surprising that certain great poets and critics have been remarkable for the vigour of their imagery, and dependent upon it. No one would deny the usefulness of imagery to some people; the mistake is to suppose that it is indispensable to all.
Articulatory imagery is less noticeable; yet the quality of silent speech is perhaps even more dependent upon these images than upon sound-images. Collocations of syllables which are awkward or unpleasant to utter are rarely delightful to the ear. As a rule the two sets of images are so intimately connected that it is difficult to decide which is the offender. In ‘Heaven, which man’s generation draws,’ the sound doubtless is as harsh as the movements required are cramping to the lips.
The extent to which interference with one set of images will change the other may be well seen by a simple experiment. Most people, if they attempt a silent recitation while opening the mouth to its fullest stretch or holding the tongue firmly between the teeth, will notice curious transformations in the auditory images. How the experiment should be interpreted is uncertain, but it is of use in making the presence of both kinds of verbal imagery evident to those who may have overlooked them hitherto. Images of articulation should not, however, be confused with those minimal actual movements which for some people (for all, as behaviourists maintain) accompany the silent rehearsing of words.
These two forms of tied imagery might also be called verbal images, and supply the elements of what is called the ‘formal structure’ of poetry. They differ from those to which we now proceed in being images of words, not of things words stand for, and in their very close connection with the visual sensations of printed words.
Free Imagery.—Free images, or rather one form of these, visual images, pictures in the mind’s eye, occupy a prominent place in the literature of criticism, to the neglect somewhat of other forms of imagery, since, as was remarked in a preceding chapter, for every possible kind of sensation there is a corresponding possible image.
The assumption, natural before investigation, that all attentive and sensitive readers will experience the same images, vitiates most of the historical discussions from that of Longinus to that of Lessing. Even in the present day, when there is no excuse for such ignorance, the mistake still thrives, and an altogether too crude, too hasty, and too superficial form of criticism is allowed to pass unchallenged. It cannot be too clearly recognised that individuals differ not only in the type of imagery which they employ, but still more in the particular images which they produce. In their whole reactions to a poem, or to a single line of it, their free images are the point at which two readings are most likely to differ, and the fact that they differ may very well be quite immaterial. Fifty different readers will experience not one common picture but fifty different pictures. If the value of the poem derived from the value qua picture of the visual image excited then criticism might well despair. Those who would stress this part of the poetic reaction can have but crude views on pictures.
But if the value of the visual image in the experience is not pictorial, if the image is not to be judged as a picture, how is it to be judged? It is improbable that the many critics, some of them peculiarly well qualified in the visual arts, who have insisted upon the importance of imagery, have been entirely wasting their time. It ought to be possible to give an account of the place of free imagery in the whole poetic experience which will explain this insistence. What is required will be found if we turn our attention from the sensory qualities of the imagery to the more fundamental qualities upon which its efficacy in modifying the rest of the experience depends. It has been urged above that images which are different in their sensory qualities may have the same effects. If this were not the case the absence of glaring differences between people of different image-types would be astonishing. But since images may represent sensations without resembling them, and represent them in the sense of replacing them, as far as effects in directing thought and arousing emotion go, differences in their mimetic capacity become of minor importance. As we have seen, it is natural for those whose imagery is vivid, to suppose that vivacity and clearness go together with power over thought and feeling. It is the power of an image over these that is as a rule being praised when an intelligent and sensitive critic appears merely to be praising the picture floating before his mind’s eye. To judge the image as a picture is judged, would, as we have seen, be absurd; and what is sought in poetry by those painters and others whose interest in the world is primarily visual is not pictures but records of observation, or stimuli of emotion.
