Another problem at once obvious is to determine the limits of a phrase. Some readers will feel "to fortune" in the above sentence as a separate phrase, others will join it to the three words that precede. No rules can be laid down. Two tentative but useful criteria are possible, however. A phrase may be regarded as purely musical, a group of sounds that either by their own nature or by their possibility of utterance in a single expulsion of breath seem to belong together. But this is an uncertain criterion, since we separate the sounds of words with great difficulty from their meaning, and the periods of breathing are subject to arbitrary control. And some phrases are uttered in much less than the time required in normal breathing. The other criterion, sometimes supporting sometimes contradicting the former, is the logical content of words. But this also is uncertain, since logical content ought to hold subject and verb together, whereas in the example above it clearly does not. And neither breath grouping nor logical grouping will enable us to determine whether "either of virtue or of mischief" is two phrases or one.

The limits of the sentence, with its clauses, are, largely through the modern conventions of printing, more distinctly felt and observed. But its rhythm is none the less complex. For it is not only the sum of the smaller rhythmic movements of word and phrase and clause, but forms a new entity of itself, created by the union of the lesser elements—just as a building is more than its component bricks, stones, and timbers.

Composite Speech Rhythm. Such, briefly described, are the rhythmic elements of spoken English prose. When only small sections are analyzed singly, it is possible to understand something, at least, of the intricate pattern of forces which are interwoven in the rhythms of ordinary language. When one undertakes to analyze and express the combined rhythms—musical, logical, emotional—of connected sentences and paragraphs, one finds no system of notation adequate; the melodies and harmonies disappear in the process of being explained. Those who wish to enjoy to the fullest the rhythmic beauties of English prose must patiently scrutinize the smallest details, then study the details in larger and still larger combinations—the balance and contrast of phrases, the alternation of dependent and independent clauses, the varieties of long and short sentences, of simple, compound, periodic sentences—and finally endeavor to rejoin the parts into a complete whole. To pursue the subject further would be to encroach upon the domain of formal rhetoric and would be out of place here. The best counsel is the old counsel: try to understand and feel the great passages of the great prose masters. A few examples have been given on pages 25 ff., above; they should be studied diligently.

Prose and Verse Rhythm. It is but a short step from the occasional regularity of rhythm in the passages on pages 27-29 to the deliberately continuous regularity of verse. A tendency to rhythmic flow, it has already been shown, is inherent in ordinary language. When the words are made to convey heightened emotion this tendency is increased, and "the deeper the feeling, the more characteristic and decided the rhythm" (John Stuart Mill). Then, as Coleridge says, "the wheels take fire from the mere rapidity of their motion," and finally we have

high and passionate thoughts
To their own music chanted.

Intensified, regularized rhythm is reciprocally both a result of impassioned feeling and a cause of it: hence its double function in poetry. It springs, on the one hand, from "the high spiritual instinct of the human being impelling us to seek unity by harmonious adjustment and thus establishing the principle that all the parts of an organized whole must be assimilated to the more important and essential parts." On the other hand, it "resembles (if the aptness of the simile may excuse its meanness) yeast, worthless or disagreeable by itself, but giving vivacity and spirit to the liquor with which it is proportionally combined."[19]

The question is as old as Aristotle, whether metre, that is, regularized rhythm, is an inalienable and necessary concomitant of poetry. The answer rests on a precise understanding of terms; for the right antithesis, so far as there is one, is not between prose and poetry, but between prose and verse. High and passionate thoughts, true poetical feeling and expression may and do exist in prose, but their most natural and characteristic expression is in verse. The old question has been lately reopened, however, by the anomalous form called 'free-verse.' Only the name is new; the thing itself is, at its best, but a carefully rhythmed prose printed in a new shape: an effort to combine in an effective union some of the characteristics of spatial rhythm with the established temporal rhythms of language. Free-verse will be discussed more fully on a later page; it is mentioned here because it is a natural transition between prose and verse, claiming as it does the freedom of the one and the powers of the other.

Another means of recognizing the close relations of verse and prose is to try to determine which of several passages of similarly heightened emotion, printed in the same form, was originally verse and which prose.

Yet, as I would not catch your love with a lie, but force you to love me as I am, faulty, imperfect, human, so I would not cheat your inward being with untrue hopes nor confuse pure truth with a legend. This only I have: I am true to my truth, I have not faltered; and my own end, the sudden departure from the virile earth I love so eagerly, once such a sombre matter, now appears nothing beside this weightier, more torturing bereavement.
