Each stinging-needle tapers from a broad base to a slender summit, which, though rounded at the end, is of such microscopic fineness that it readily penetrates, and breaks off in, the skin. The whole hair consists of a very delicate outer case of wood, closely applied to the inner surface of which is a layer of semi-fluid matter full of innumerable granules of extreme minuteness. This semi-fluid lining is protoplasm, which thus constitutes a kind of bag, full of limpid liquid, and roughly corresponding in form with the interior of the hair which it fills.[119]

This is, of course, the “loose” sentence of traditional rhetorical analysis, and it has no dramatic force; yet it is for this very reason adapted to the scientist’s purpose.[120] The rhetorical adaptation shows in the accommodation of a little hierarchy of details.

This appears to be the sentence of a developed mentality also, because it is created through a patient, disciplined observation, and not through impression, as the simple sentence can be. To the infant’s mind, as William James observed in a now famous passage, the world is a “buzzing, blooming confusion,” and to the immature mind much older it often appears something done in broad, uniform strokes. But to the mind of a trained scientist it has to appear a cosmos—else, no science. So in Huxley the objective world is presented as a series of details, each of which has its own cluster of satellites in the form of minor clauses. This is the way the world has to be reported when our objective is maximum perception and minimum desire to obtrude or influence.

Henry James was explaining with a somewhat comparable interest a different kind of world, in which all sorts of human and non-material forces are at work, and he tried with extreme conscientiousness to measure them. In that process of quantification and qualification the complex sentence was often brought by him to an extraordinary height of ramification.

In summation, then, the complex sentence is the branching sentence, or the sentence with parts growing off other parts. Those who have used it most properly have performed a second act of analysis, in which the objects of perception, after being seen discretely, are put into a ranked structure. This type of sentence imposes the greatest demand upon the reader because it carries him farthest into the reality existing outside self. This point will take on importance as we turn to the compound sentence.

The structure of the compound sentence often reflects a simple artlessness—the uncritical pouring together of simple sentences, as in the speech of Huckleberry Finn. The child who is relating an adventure is likely to make it a flat recital of conjoined simple predications, because to him the important fact is that the things were, not that they can be read to signify this or that. His even juxtapositions are therefore sometimes amusing, for now and then he will produce a coordination that unintentionally illuminates. This would, of course, be a result of lack of control over the rhetoric of grammar.

On the other hand, the compound sentence can be a very “mature” sentence when its structure conforms with a settled view of the world. The latter possibility will be seen as we think of the balance it presents. When a sentence consists of two main clauses we have two predications of similar structure bidding for our attention. Our first supposal is that this produces a sentence of unusual tension, with two equal parts (and of course sometimes more than two equal parts) in a sort of competition. Yet it appears on fuller acquaintance that this tension is a tension of stasis, and that the compound sentence has, in practice, been markedly favored by periods of repose like that of the Eighteenth century. There is congeniality between its internal balance and a concept of the world as an equilibrium of forces. As a general rule, it appears that whereas the complex sentence favors the presentation of the world as a system of facts or as a dynamism, the compound sentence favors the presentation of it in a more or less philosophical picture. This world as a philosophical cosmos will have to be a sort of compensatory system. We know from other evidences that the Eighteenth century loved to see things in balance; in fact, it required the idea of balance as a foundation for its institutions. Quite naturally then, since motives of this kind reach into expression-forms, this was the age of masters of the balanced sentence—Dryden, Johnson, Gibbon, and others, the genre of whose style derives largely from this practice of compounding. Often the balance which they achieved was more intricate than simple conjunction of main clauses because they balanced lesser elements too, but the informing impulse was the same. That impulse was the desire for counterpoise, which was one of the powerful motives of their culture.

In this pattern of balance, various elements are used in the offsettings. Thus when one attends closely to the meanings of the balanced parts, one finds these compounds recurring: an abstract statement is balanced (in a second independent clause) by a more concrete expression of the same thing; a fact is balanced by its causal explanation; a statement of positive mode is balanced by one of negative mode; a clause of praise is balanced by a clause of qualified censure; a description of one part is balanced by a description of a contrasting part, and so on through a good many conventional pairings. Now in these collocations cause and effect and other relationships are presented, yet the attempt seems not so much to explore reality as to clothe it in decent form. Culture is a delicate reconciliation of opposites, and consequently a man who sees the world through the eyes of a culture makes effort in this direction. We know that the world of Eighteenth century culture was a rationalist world, and in a rationalist world everything must be “accounted for.” The virtue of the compound sentence is that its second part gives “the other half,” so to speak. As the pattern works out, every fact has its cause; every virtue is compensated for by a vice; every excursion into generality must be made up for by attention to concrete circumstances and vice versa. The perfection of this art form is found in Johnson and Gibbon, where such pairings occur with a frequency which has given rise to the phrase “the balanced style.” When Gibbon, for example, writes of religion in the Age of the Antonines: “The superstition of the people was not embittered by any mixture of theological rancour; nor was it confined by the chains of any speculative system,”[121] we have almost the feeling that the case of religion has been settled by this neat artifice of expression. This is a “just” view of affairs, which sees both sides and leaves a kind of balanced account. It looks somewhat subjective, or at least humanized; it gives us the gross world a little tidied up by thought. Often, moreover, this balance of structure together with the act of saying a thing equivocally—in the narrower etymological sense of that word—suggests the finality of art. This will be found true of many of the poetical passages of the King James Bible, although these come from an earlier date. “The heavens declare the glory of God; and the firmament sheweth his handiwork”; “Man cometh forth as a flower and is cut down; he fleeth also as a shadow and continueth not.” By thus stating the matter in two ways, through balanced clauses, the sentence achieves a degree of formal completeness missing in sentences where the interest is in mere assertion. Generally speaking the balanced compound sentence, by the very contrivedness of its structure, suggests something formed above the welter of experience, and this form, as we have by now substantially said, transfers something of itself to the meaning. In declaring that the compound sentence may seem subjective, we are not saying that it is arbitrary, its correspondence being with the philosophical interpretation rather than with the factual reality. Thus if the complex sentence is about the world, the compound sentence is about our idea about the world, into which some notion of compensation forces itself. One notices that even Huxley, when he draws away from his simple expositions of fact and seeks play for his great powers of persuasion, begins to compound his sentences. On the whole, the compound sentence conveys that completeness and symmetry which the world ought to have, and which we manage to get, in some measure, into our most satisfactory explanations of it. It is most agreeable to those ages and those individuals who feel that they have come to terms with the world, and are masters in a domain. But understandably enough, in a world which has come to be centrifugal and infinite, as ours has become since the great revolutions, it tends to seem artificial and mechanical in its containment.

Since the difference between sentence and clause is negligible as far as the issues of this subject are concerned, we shall next look at the word, and conclude with a few remarks on some lesser combinations. This brings up at once the convention of parts of speech. Here again I shall follow the traditional classification, on the supposition that categories to which usage is referred for correction have accumulated some rhetorical force, whatever may be said for the merits of some other and more scientific classification.
