STRUCTURE. In any work of literature there should be definite structure. This requires, (1) Unity, (2) Variety, (3) Order, (4) Proportion, and (5) due Emphasis of parts. Unity means that everything included in the work ought to contribute directly or indirectly to the main effect. Very often a definite theme may be found about which the whole work centers, as for instance in 'Macbeth,' The Ruin of a Man through Yielding to Evil. Sometimes, however, as in a lyric poem, the effect intended may be the rendering or creation of a mood, such as that of happy content, and in that case the poem may not have an easily expressible concrete theme.
Order implies a proper beginning, arrangement, progress, and a definite ending. In narrative, including all stories whether in prose or verse and also the drama, there should be traceable a Line of Action, comprising generally: (1) an Introduction, stating the necessary preliminaries; (2) the Initial Impulse, the event which really sets in motion this particular story; (3) a Rising Action; (4) a Main Climax. Sometimes (generally, in Comedy) the Main Climax is identical with the Outcome; sometimes (regularly in Tragedy) the Main Climax is a turning point and comes near the middle of the story. In that case it really marks the beginning of the success of the side which is to be victorious at the end (in Tragedy the side opposed to the hero) and it initiates (5) a Falling Action, corresponding to the Rising Action, and sometimes of much the same length, wherein the losing side struggles to maintain itself. After (6) the Outcome, may come (7) a brief tranquilizing Conclusion. The Antecedent Action is that part of the characters' experiences which precedes the events of the story. If it has a bearing, information about it must be given either in the Introduction or incidentally later on. Sometimes, however, the structure just indicated may not be followed; a story may begin in the middle, and the earlier part may be told later on in retrospect, or incidentally indicated, like the Antecedent Action.
If in any narrative there is one or more Secondary Action, a story which might be separated from the Main Action and viewed as complete in itself, criticism should always ask whether the Main and Secondary Actions are properly unified. In the strictest theory there should be an essential connection between them; for instance, they may illustrate different and perhaps contrasting aspects of the general theme. Often, however, an author introduces a Secondary Action merely for the sake of variety or to increase the breadth of his picture—in order to present a whole section of society instead of one narrow stratum or group. In such cases, he must generally be judged to have succeeded if he has established an apparent unity, say by mingling the same characters in the two actions, so that readers are not readily conscious of the lack of real structural unity.
Other things to be considered in narrative are: Movement, which, unless for special reasons, should be rapid, at least not slow and broken; Suspense; general Interest; and the questions whether or not there are good situations and good minor climaxes, contributing to the interest; and whether or not motivation is good, apart from that which results from character, that is whether events are properly represented as happening in accordance with the law of cause and effect which inexorably governs actual life. But it must always be remembered that in such writing as Comedy and Romance the strict rules of motivation must be relaxed, and indeed in all literature, even in Tragedy, the idealization, condensation, and heightening which are the proper methods of Art require them to be slightly modified.
DESCRIPTIVE POWER. Usually secondary in appearance but of vital artistic importance, is the author's power of description, of picturing both the appearance of his characters and the scenes which make his background and help to give the tone of his work. Perhaps four subjects of description may be distinguished: 1. External Nature. Here such questions as the following are of varying importance, according to the character and purpose of the work: Does the author know and care for Nature and frequently introduce descriptions? Are the descriptions concrete and accurate, or on the other hand purposely general (impressionistic) or carelessly superficial? Do they give fine variations of appearance and impression, such as delicate shiftings of light and shade and delicate tones of color? Are they powerfully sensuous, that is do they appeal strongly to the physical senses, of sight (color, light, and movement), sound (including music), smell, taste, touch, and general physical sensation? How great is their variety? Do they deal with many parts of Nature, for example the sea, mountains, plains, forests, and clouds? Is the love of external beauty a passion with the author? What is the author's attitude toward Nature—(1) does he view Nature in a purely objective way, as a mass of material things, a series of material phenomena or a mere embodiment of sensuous beauty; or (2) is there symbolism or mysticism in his attitude, that is—does he view Nature with awe as a spiritual power; or (3) is he thoroughly subjective, reading his own moods into Nature or using Nature chiefly for the expression of his moods? Or again, does the author describe with merely expository purpose, to make the background of his work clear? 2. Individual Persons and Human Life: Is the author skilful in descriptions of personal appearance and dress? Does he produce his impressions by full enumeration of details, or by emphasis on prominent or characteristic details? How often and how fully does he describe scenes of human activity (such as a street scene, a social gathering, a procession on the march)? 3. How frequent and how vivid are his descriptions of the inanimate background of human life—buildings, interiors of rooms, and the rest? 4. Does the author skilfully use description to create the general atmosphere in which he wishes to invest his work—an atmosphere of cheerfulness, of mystery, of activity, or any of a hundred other moods?
STYLE. Style in general means 'manner of writing.' In the broad sense it includes everything pertaining to the author's spirit and point of view—almost everything which is here being discussed. More narrowly considered, as 'external style,' it designates the author's use of language. Questions to be asked in regard to external style are such as these: Is it good or bad, careful or careless, clear and easy or confused and difficult; simple or complex; terse and forceful (perhaps colloquial) or involved and stately; eloquent, balanced, rhythmical; vigorous, or musical, languid, delicate and decorative; varied or monotonous; plain or figurative; poor or rich in connotation and poetic suggestiveness; beautiful, or only clear and strong? Are the sentences mostly long or short; periodic or loose; mostly of one type, such as the declarative, or with frequent introduction of such other forms as the question and the exclamation?
POETRY. Most of what has thus far been said applies to both Prose and Poetry. But in Poetry, as the literature especially characterized in general by high Emotion, Imagination, and Beauty, finer and more delicate effects are to be sought than in Prose. Poetry, generally speaking, is the expression of the deeper nature; it belongs peculiarly to the realm of the spirit. On the side of poetical expression such imaginative figures of speech as metaphors and similes, and such devices as alliteration, prove especially helpful. It may be asked further of poetry, whether the meter and stanza structure are appropriate to the mood and thought and so handled as to bring out the emotion effectively; and whether the sound is adapted to the sense (for example, musical where the idea is of peace or quiet beauty). If the sound of the words actually imitates the sound of the thing indicated, the effect is called Onomatopoeia. Among kinds of poetry, according to form, the most important are: (1) Narrative, which includes many subordinate forms, such as the Epic. (2) Lyric. Lyric poems are expressions of spontaneous emotion and are necessarily short. (3) Dramatic, including not merely the drama but all poetry of vigorous action. (4) Descriptive, like Goldsmith's 'Deserted Village' and Tennyson's 'Dream of Fair Women.' Minor kinds are: (5) Satiric; and (6) Didactic.
Highly important in poetry is Rhythm, but the word means merely 'flow,' so that rhythm belongs to prose as well as to poetry. Good rhythm is merely a pleasing succession of sounds. Meter, the distinguishing formal mark of poetry and all verse, is merely rhythm which is regular in certain fundamental respects, roughly speaking is rhythm in which the recurrence of stressed
