(Notice the use of the semicolon in the last two groups of sentences. The parts of compound sentences such as these should be separated by semicolons.)
Short Sentences. Having determined approximately what relations [204] may be grouped in a single sentence, the first question for consideration is whether sentences should be long or short. This cannot be definitely answered. Since they should be concise, the short sentence is well suited for definitions. Since a proposition should be announced in as few words as can be used, without sacrificing brevity to clearness, short sentences serve best for this purpose. As changes in the direction of the development of a thought should be quickly indicated, a short sentence is generally used for transition. And as at times when the mind is under a stress of strong feeling, or the action of a story is rapid, all explanatory matters are cut away, the barest statements in shortest sentences serve best to express strong emotion and rapid action.
Long Sentences. Long sentences have the very opposite uses. To amplify a topic, to develop a proposition by repetition, by details, by proofs, or by example, long sentences are serviceable; by them the finer modifications of a thought can be expressed. So, too, a summary of a paragraph or a chapter frequently employs long sentences to express the whole thought with precision and with proper subordination of parts. Again, as short sentences best express haste and intensity, so long sentences give the feeling of quiet deliberation and dignified calm.
Illustrations of definitions, propositions, transitions, and exemplifications are to be found everywhere. Slow movement expressed by long sentences is well illustrated in Irving and Hawthorne. One selection from George Meredith, to show the peculiar adaptation of the short sentence to express intensity of feeling, is given. Richard Feverel has just learned that the wife whom he had deserted has borne him a son. Description and narration are mingled. The short, nervous sentences [205] express both the vividness of his impressions and the intensity of his emotions.
“A pale gray light on the skirts of the flying tempest displayed the dawn. Richard was walking hurriedly. The green drenched woods lay all about his path, bent thick, and the forest drooped glimmeringly. Impelled as a man who feels a revelation mounting obscurely to his brain, Richard was passing one of those little forest-chapels, hung with votive wreaths, where the peasants halt to kneel and pray. Cold, still, in the twilight it stood, rain-drops pattering round it. He looked within, and saw the Virgin holding her Child. He moved not by. But not many steps had he gone before the strength went out of him, and he shuddered. What was it? He asked not. He was in other hands. Vivid as lightning the Spirit of Life illumined him. He felt in his heart the cry of his child, his darling’s touch. With shut eyes he saw them both. They drew him from the depths; they led him a blind and tottering man. And as they led him he had a sense of purification so sweet he shuddered again and again.”
Unity. In a sentence, as in a theme or a paragraph, the first question regarding its structure is what to put into it. The germ of a paragraph is usually a sentence; of the sentence it is one word or but very few words. This kernel of a sentence may be developed through the many modifications of the thought; but always the additions must be distinctly related to the germ words. If this relation of parts to the kernel of the sentence be unmistakable, the sentence has unity; if there are parts whose connection with the germ of the sentence cannot be easily traced, they should be rejected as belonging to another sentence. The pith of the whole sentence can be stated in a few words, if the sentence has unity.
Long sentences should be watched. One thing easily suggests another, interesting too, it may be; and when [206] an essay is to be written, anything,—especially if it have so worthy a quality as interest to recommend it,—anything is allowed to go in. Such a sentence as the following can be explained on no other principle: “Just then James came rushing downstairs like mad to find the fellow who had punched a hole in the tire of his bicycle, which was a Columbia which he got two years before at a second-hand store, paying for it in work at fifteen cents an hour.” Plainly everything after “bicycle” is nothing to the present purpose and should be excluded. The following from a description of Cologne Cathedral is as bad, in some respects, worse; for there is one point where the break is so abrupt that a child would detect it. “The superintendence was intrusted to Mr. Ahlert, whose ideas were not well adapted to inspire him for his grand task, under his direction much of the former beauty and artistical skill was lost sight of, but at all events it was a great satisfaction to see the work go on and to have the expenses defrayed by the State.” In this case the writer, beyond doubt, thinks long sentences the correct thing. Long sentences are necessary at times; but the desire simply to write long sentences or to fill up space should never lead one to forget that a sentence is the expression of one—not more—of one complete thought.
On the other hand, sentences should contain the whole of one thought; none of it should run over into another sentence. Strange as it may seem, sentences are sometimes found like the following: “James was on the whole a bad boy. But he had some redeeming qualities.” “The first day at school was all new to me. While it was interesting as well.” “He said that he was going. And that I might go with him.” There is no ground for an explanation of such errors [207] as these except laziness and grossest illiteracy. It is by no device so simple as the insertion of a period that man can separate what has been joined in thought. And and but rarely begin sentences; in nearly all cases it will be found that the sentences they purport to connect are but the independent clauses of one compound sentence. While or any other subordinating conjunction introduces a dependent clause; a dependent clause is not a sentence; it can never stand alone.
The offenses against the unity of a sentence are including too much and including too little. Both are the result of carelessness or inability to think. The purpose, the kernel, the germ of the sentence, should be so clearly in mind that every necessary modification of the thought shall be included and every unnecessary phrase be excluded. Some further suggestions concerning unity are found in the paragraphs treating primarily of mass and coherence.
Mass. As advance is made in the ability to grasp quickly the thought of a book, it becomes more and more evident that the eye must be taken into account when arranging the parts of a composition. The eye sees the headings of the chapters; it catches the last words of one paragraph and the first words of the next; it lights upon the words near the periods; so the parts of a composition should be arranged so that these points shall contain worthy words. Moreover, within the sentence the colon marks the greatest independence of the parts; the semicolon comes next; and the comma marks the smallest division of thought. Following the guidance of the eye, then, the words before a period should be the most important; those near a colon, a semicolon, and a comma will have a descending scale of value. A speaker has no difficulty with punctuation; unconsciously he pauses with the [208] thought. So true is this, that one is inclined to say that if the writer will read aloud his own composition, and punctuate where he pauses in the reading, always remembering the rank of the marks of punctuation, he will not be far from right. It will be noticed that he has paused in the reading after important words, as if the thought stayed a moment there for the help of the reader. Naturally we pause after important words; and conversely, the places of importance in a sentence are near the marks of punctuation, increasing from the comma to the period.
