Coleridge, with his subtle builder's instinct, uses his favorite word "synthesis" not merely as applied to images as such, but to all the faculties of the soul:
"The poet, described in ideal perfection, brings the whole soul of man into activity, with the subordination of its faculties to each other according to their relative worth and dignity. He diffuses a tone and a spirit of unity, that blends, and as it were fuses, each into each, by that synthetic and magical power to which I would exclusively appropriate the name of Imagination." "Synthetic and magical power," indeed, with a Coleridge as Master of the Mysteries! But the perplexed student of poetry may well wish a more exact description of what really takes place.
An American critic, after much searching in recent psychological explanations of artistic creation, attempts to describe the genesis of a poem in these words: [Footnote: Lewis E. Gates, Studies and Appreciations, p. 215. Macmillan, 1900.]
"The poet concentrates his thought on some concrete piece of life, on some incident, character, or bit of personal experience; because of his emotional temperament, this concentration of interest stirs in him a quick play of feeling and prompts the swift concurrence of many images. Under the incitement of these feelings, and in accordance with laws of association that may at least in part be described, these images grow bright and clear, take definite shapes, fall into significant groupings, branch and ramify, and break into sparkling mimicry of the actual world of the senses—all the time delicately controlled by the poet's conscious purpose and so growing intellectually significant, but all the time, if the work of art is to be vital, impelled also in their alert weaving of patterns by the moods of the poet, by his fine instinctive sense of the emotional expressiveness of this or that image that lurks in the background of his consciousness. For this intricate web of images, tinged with his most intimate moods, the poet through his intuitive command of words finds an apt series of sound-symbols and records them with written characters. And so a poem arises through an exquisite distillation of personal moods into imagery and into language, and is ready to offer to all future generations its undiminishing store of spiritual joy and strength."
A better description than this we are not likely to find, although some critics would question the phrase, "all the time delicately controlled by the poet's conscious purpose." [Footnote: "Poetry is not like reasoning, a power to be exerted according to the determination of the will. A man cannot say, 'I will compose poetry.'. . . It is not subject to the control of the active powers of the mind. … Its birth and recurrence have no necessary connection with the consciousness or will." Shelley, A Defense of Poetry.]
For sometimes, assuredly, the synthesis of images seems to take place without the volition of the poet. The hypnotic trance, the narcotic dream or revery, and even our experience of ordinary dreams, provide abundant examples. One dreams, for instance, of a tidal river, flowing in with a gentle full current which bends in one direction all the water-weeds and the long grasses trailing from the banks; then somehow the tide seems to change, and all the water and the weeds and grasses, even the fishes in the stream, turn slowly and flow out to sea. The current synthesizes, harmonizes, moves onward like music,—and we are aware that it is all a dream. Coleridge's "Kubla Khan," composed in a deep opium slumber, moves like that, one train of images melting into another like the interwoven figures of a dance led by the "damsel with a dulcimer." There is no "conscious purpose" whatever, and no "meaning" in the ordinary interpretation of that word. Nevertheless it is perfect integration of imagery, pure beauty to the senses. Something of this rapture in the sheer release of control must have been in Charles Lamb's mind when he wrote to Coleridge about the "pure happiness" of being insane. "Dream not, Coleridge, of having tasted all the grandeur and wildness of fancy till you have gone mad! All now seems to me vapid, comparatively so." (June 10, 1796.)
If "Kubla Khan" represents one extreme, Poe's account of how he wrote "The Raven" [Footnote: The Philosophy of Composition.] —incredible as the story appears to most of us—may serve to illustrate the other, namely, a cool, conscious, workmanlike control of every element in the selection and combination of imagery. Wordsworth's naive explanation of the task performed by the imagination in his "Cuckoo" and "Leech-Gatherer" [Footnote: Preface to poems of 1815-1845.] occupies a middle ground. We are at least certain of his entire honesty—and incidentally of his total lack of humor!
"'Shall I call thee Bird,
Or but a wandering Voice?'
"This concise interrogation characterizes the seeming ubiquity of the voice of the cuckoo, and dispossesses the creature almost of a corporeal existence; the Imagination being tempted to this exertion of her power by a consciousness in the memory that the cuckoo is almost perpetually heard throughout the season of spring, but seldom becomes an object of sight….
"'As a huge stone is sometimes seen to lie
Couched on the bald top of an eminence,
Wonder to all who do the same espy
By what means it could thither come, and whence,
So that it seems a thing endued with sense,
Like a sea-beast crawled forth, which on a shelf
Of rock or sand reposeth, there to sun himself.
