The following illustrates the weakness of closing with a specific instance when it does not rise to the level of the remainder of a paragraph. The last sentence would better be omitted.
“We often hear of the magical influence of poetry. The expression in general means nothing; but, applied to the writings of Milton, it is most appropriate. His poetry acts like an incantation. Its merit lies less in its obvious meaning than in its occult power. There would seem, at first sight, to be no more in his words than in other words. But they are words of enchantment. No sooner are they pronounced than the past is present and the distant near. New forms of beauty start at once into existence, and all the burial-places of memory give up their dead. Change the structure of the sentence, substitute one synonym for another, and the whole effect is destroyed. The spell loses its power; and he who should then hope to conjure with it would find himself as much mistaken as Cassim in the Arabian tale, when he stood crying, ‘Open Wheat,’ ‘Open Barley,’ to the door which obeyed no sound but ‘Open Sesame.’ In the miserable failure of Dryden in his attempt to translate into his own diction some parts of the ‘Paradise Lost’ is a remarkable instance of this.” (“Essay on Milton,” by Macaulay.)
Length of opening and closing Sentences. By examination, one finds that the first sentence of a paragraph of exposition and of argument is usually a terse statement of the proposition; and that after the proposition has been established there follows a longer sentence gathering up all the points of the discussion into a full, rounded period which forms a suitable climax and conclusion of the [179] paragraph. Of Macaulay’s “Milton” one is quite inside the truth when he says that of those paragraphs containing an opening topic-sentence and its restatement as a conclusion, the closing sentence is the longer in the ratio of two to one. In Burke’s “Conciliation,” the ratio rises as high as four to one. There are, however, exceptions to the rule. Paragraphs sometimes close with a shorter statement of the proposition, a sort of aphorism or epigram. As this kind of sentence is fascinating, some books have said that paragraphs should close so; that it is like cracking a whip, and gives a snap to the paragraph not gained in any other way. Even if readers enjoyed having paragraphs close in this cracking manner, it must be borne in mind that not all conclusions are capable of such a statement, and, what is worse, that the tendency to seek for epigrams leads to untruth and a degenerated form of witticism. Such forced sentences are only half truths, or they are a bit of cheap repartee. Such a close is effective, if the whole truth can be so expressed; but to seek for such sentences is dangerous. The best rule is the one already stated; it applies to the long sentence and the short sentence alike. It is that a paragraph should close with words that deserve distinction.
Proportion. The body of a paragraph should have the matter so proportioned that the more important points shall receive the longer treatment. In a paragraph of proof, details, or comparison, that point in the proof, that particular, that part of the comparison, which for the specific purpose has most significance, should have proportionately fuller treatment. It is the same principle already noticed in exposition. Indicate the relative importance of topics in a paragraph by the relative number of words used in their treatment.
For mass in a paragraph, then, keep in mind that [180] the last sentence should contain matter and form worthy of the position it occupies; that the position of next importance is at the beginning; and that the relative importance of the matters in the body of a paragraph is pretty correctly indicated by the relative length of treatment.
Coherence and Clearness. Coherence, the third principle of structure, is the most important; and it is the most difficult to apply. For one can make a beginning and an end, he can select his materials so that there is unity, but to make all the parts stick together, to arrange the sentences so that one grows naturally from the preceding and leads into the next, requires nice adjustment of parts, and rewriting many times. How essential coherence in a paragraph is, simply to make the thought easy to grasp, may be seen by taking a paragraph to pieces and mixing up its sentences, and at the same time removing all words that bind its parts together. The following can hardly be understood at all, but in its original condition it is so clear that it cannot be misunderstood. If the sentences be arranged in the following order, the original paragraph will appear: 1, 5, 3, 9, 8, 6, 2, 4, 7, 10.
1. “The first question which obviously suggests itself is how these wonderful moral effects are to be wrought under the instrumentality of the physical sciences. 2. To know is one thing, to do is another; the two things are altogether distinct. 3. Does Sir Robert Peel mean to say, that whatever be the occult reasons for the result, so it is; you have but to drench the popular mind with physics, and moral and religious advancement follows on the whole, in spite of individual failures? 4. A man knows he should get up in the morning,—he lies abed; he knows he should not lose his temper, yet he cannot keep it. 5. Can the process be analyzed and drawn out, or does it act like a dose or a charm which comes [181] into general use empirically? 6. It is natural and becoming to seek for some clear idea of the meaning of so dark an oracle. 7. A laboring man knows he should not go to the ale-house, and his wife knows she should not filch when she goes out charing, but, nevertheless, in these cases, the consciousness of a duty is not all one with the performance of it. 8. Or rather, does he mean, that, from the nature of the case, he who is imbued with science and literature, unless adverse influences interfere, cannot but be a better man? 9. Yet when has the experiment been tried on so large a scale as to justify such anticipations? 10. There are, then, large families of instances, to say the least, in which men may become wiser, without becoming better; what, then, is the meaning of this great maxim in the mouth of its promulgators?”
Coherence, so necessary to the easy understanding of a paragraph, is gained in three ways: by the order in which the sentences are arranged; by the use of parallel constructions for parallel ideas; and by the use of connectives.
Two Arrangements of Sentences in a Paragraph. Material which has been selected with regard to the principle of unity is all informed with one idea. Yet though one thought runs through it all and unites it, the parts do not stand in an equally close relation to the conclusion, nor is each part equally related to every other part. Had they been, the last paragraph quoted would have been as well in one order as another. Rather the sentences seem to fall into groups of more closely related matters; or at times one sentence seems to follow as the direct consequence of the preceding sentence. With respect to the way in which the sentences contribute to the topic of the paragraph, whether the topic be announced first or last, sentences may be said to contribute directly to the proposition or indirectly. If [182] directly, the paragraph is a collection of sentences, each having a common purpose, each having a similar relation to the topic, arranged, as it were, side by side, and advancing as one body to the conclusion. This may be termed an individual arrangement of sentences, since as individuals they each contribute to the topic. The conclusion derives its force from the combined mass of all. If indirectly, the paragraph is a series of sentences, each growing out of the one preceding it, each receiving a push from the sentence before, and the last having the combined force of all. This may be styled a serial arrangement of sentences, since in such a case each contributes to the topic only as one in a chain. The former overcomes by its mass; the latter strikes by reason of its velocity. The one advances in rank; the other advances in single file.
An illustration of each will help to an understanding of this. In the following paragraph from Macaulay’s essay on Milton, each of the details mentioned points directly to “those days” when the race became a “byword and a shaking of the head to the nations.” Their aggregate mass enforces the topic of the paragraph. They are all one body equally informed with the common principle which is the topic. Notice that one sentence is not the source of the next, but that all the sentences stand in a similar relation to the conclusion. This arrangement is common in description. In the second paragraph, from Irving’s “Legend of Sleepy Hollow,” each detail contributes to the appearance of Ichabod, not through some other sentence, but directly.
