Obverse. A fourth method of building up a paragraph from a topic-sentence consists in telling what it is not; that is, giving the obverse. This is very effective in argument, and is employed in exposition and description. The obverse usually follows a positive statement, and again is followed by the affirmative; that is, first what it is, then what it is not, and last, what it is again. In the following description by Ruskin, the method appears and reappears. Notice the “nots” and “buts,” indicating the change from the negative to the positive statement. It would be a sacrilege to omit the last paragraph, though it does not illustrate this manner of development.
“For all other rivers there is a surface, and an underneath, and a vaguely displeasing idea of the bottom. But the Rhone flows like one lambent jewel; its surface is nowhere, its ethereal self is everywhere, the iridescent rush and translucent strength of it blue to the shore, and radiant to the depth.
“Fifteen feet thick, not of flowing, but flying water; not water, neither—melted glacier, rather, one should call it; the force of the ice is with it, and the wreathing of the clouds, the gladness of the sky, and the continuance of Time.
[170] “Waves of clear sea are, indeed, lovely to watch, but they are always coming or gone, never in any taken shape to be seen for a second. But here was one mighty wave that was always itself, and every fluted swirl of it, constant as the wreathing of a shell. No wasting away of the fallen foam, no pause for gathering of power, no helpless ebb of discouraged recoil; but alike through bright day and lulling night, the never-pausing plunge, and never-fading flash, and never-hushing whisper, and, while the sun was up, the ever-answering glow of unearthly aquamarine, ultramarine, violet-blue, gentian-blue, peacock-blue, river-of-paradise blue, glass of a painted window melted in the sun, and the witch of the Alps flinging the spun tresses of it forever from her snow.
“The innocent way, too, in which the river used to stop to look into every little corner. Great torrents always seem angry, and great rivers are often too sullen; but there is no anger, no disdain in the Rhone. It seemed as if the mountain stream was in mere bliss at recovering itself again out of the lake-sleep, and raced because it rejoiced in racing, fain yet to return and stay. There were pieces of wave that danced all day, as if Perdita were looking on to learn; there were little streams that skipped like lambs and leaped like chamois; there were pools that shook the sunshine all through them, and were rippled in layers of overlaid ripples, like crystal sand; there were currents that twisted the light into golden braids, and inlaid the threads with turquoise enamel; there were strips of stream that had certainly above the lake been mill-stream, and were looking busily for mills to turn again; and there were shoots of stream that had once shot fearfully into the air, and now sprang up again, laughing, that they had only fallen a foot or two;—and in the midst of all the gay glittering and eddied lingering, the noble bearing by of the midmost depth, so mighty, yet so terrorless and harmless, with its swallows skimming in spite of petrels, and the dear old decrepit town as safe in the embracing sweep of it as if it were set in a brooch of sapphires.”[35]
[171] This extract from Burke’s speech is a good example of the same method.
“I put this consideration of the present and the growing numbers in the front of our deliberation, because, Sir, this consideration will make it evident to a blunter discernment than yours, that no partial, narrow, contracted, pinched, occasional system will be at all suitable to such an object. It will show you that it is not to be considered as one of those minima which are out of the eye and consideration of the law; not a paltry excrescence of the state; not a mean dependent, who may be neglected with little damage and provoked with little danger. It will prove that some degree of care and caution is required in the handling such an object; it will show that you ought not, in reason, to trifle with so large a mass of the interests and feelings of the human race. You could at no time do so without guilt; and be assured you will not be able to do it long with impunity.”[36]
Examples. A fifth method of expanding a topic is by means of illustrations and examples. It is used largely in establishing or enforcing a proposition. The author selects one example, or perhaps more than one, to illustrate his proposition. Note the words that may introduce specific instances: for example, for instance, to illustrate, a case in point, and so forth.
In the first of the following quotations, Cardinal Newman is showing that simply to acquire is not true mental enlargement. The paragraph is made up of a series of instances. The second paragraph is by Macaulay.
“The case is the same still more strikingly when the persons in question are beyond dispute men of inferior powers and deficient education. Perhaps they have been much in foreign countries, and they receive, in a passive, otiose, unfruitful way, the various facts which are forced upon them there. Seafaring men, for example, range from one [172] end of the earth to the other; but the multiplicity of external objects which they have encountered forms no symmetrical and consistent picture upon their imagination; they see the tapestry of human life, as it were, on the wrong side, and it tells no story. They sleep, and they rise up, and they find themselves, now in Europe, now in Asia; they see visions of great cities and wild regions; they are in the marts of commerce, or amid the islands of the South; they gaze on Pompey’s Pillar, or on the Andes; and nothing which meets them carries them forward or backward, to any idea beyond itself. Nothing has a drift or relation; nothing has a history or a promise. Everything stands by itself and comes and goes in its turn, like the shifting scenes of a show, which leave the spectator where he was. Perhaps you are near such a man on a particular occasion, and expect him to be shocked or perplexed at something which occurs; but one thing is much the same to him as another; or, if he is perplexed, it is as not knowing what to say, whether it is right to admire, or to ridicule, or to disapprove, while conscious that some expression of opinion is expected from him; for in fact he has no standard of judgment at all, and no landmarks to guide him to a conclusion. Such is mere acquisition, and, I repeat, no one would dream of calling it philosophy.” (“Idea of a University,” by Cardinal Newman.)
“I will give another instance. One of the most instructive, interesting, and delightful books in our language is Boswell’s ‘Life of Johnson.’ Now it is well known that Boswell’s eldest son considered this book, considered the whole relation of Boswell to Johnson, as a blot in the escutcheon of the family. He thought, not perhaps altogether without reason, that his father had exhibited himself in a ludicrous and degrading light. And thus he became so sore and irritable that at last he could not bear to hear the ‘Life of Johnson’ mentioned. Suppose that the law had been what my honorable and learned friend wishes to make it. Suppose that the copyright of Boswell’s ‘Life of Johnson’ had belonged, as it well might, during sixty years, to Boswell’s eldest son. What would have been the consequence? [173] An unadulterated copy of the finest biographical work in the world would have been as scarce as the first edition of Camden’s ‘Britannia.’“ (Speech, “Copyright,” by Macaulay.)
Combines Two or More Forms. As was said at the beginning, a paragraph is seldom made exclusively of one form. One part of the typical paragraph is usually developed more than any other and gives to the paragraph its character and its name. By far the most common variety of paragraph is that which combines two or more of the other forms. It is not necessary to cite examples; they are everywhere. Though combination is the commonest method of development, it should be guarded. It is a poor paragraph that combines the forms indiscriminately. It should follow some plan; and the best plan is the one already given in the typical paragraph.
All paragraphs, whatever be the special method of development, are governed by the three principles which have guided in the structure of whole compositions. Whether the purpose be to prove or to narrate, to enforce a conclusion or to illustrate, if a paragraph is to produce its greatest effect, it should have unity, it should be well massed, and it should be coherent.
