The universality and mutual relationship of these primal principles have, perhaps, been sufficiently set forth; and this may be the place to emphasize the second chief point,—that the perfection of this mutuality measures the degree of excellence in all objects and actions. It will everywhere appear, that, the more regular and symmetrical their relationship, the more beautiful and acceptable are its results. For example, sounds proceeding from vibrations wherein the strokes and pauses are in invariable relation are such sounds as we denominate musical. Accordingly all sounds are musical at a sufficient distance, since the most irregular undulations are, in a long journey through the air, wrought to an equality, and made subject to exact law,—as in this universe all irregularities are sure to be in the end. Thus, the thunder, which near at hand is a wild crash, or nearer yet a crazy crackle, is by distance deepened and refined into that marvellous bass which we all know. And doubtless the jars, the discords, and moral contradictions of time, however harsh and crazy at the outset, flow into exact undulation along the ether of eternity, and only as a pure proclamation of law attain to the ear of Heaven. Nay, whoso among men is able to plant his ear high enough above this rude clangor may, in like manner, so hear it, that it shall be to him melody, solace, fruition, a perpetual harvest of the heart's dearest wishes, a perpetual corroboration of that which faith affirms.
We may therefore easily understand why musical sounds are musical, why they are acceptable and moving, while those affront the sense in which the minute reposes are capricious, and, as it were, upon ill terms with the movements. The former appeal to what is most universal and cosmical within us,—to the pure Law, the deep Nature in our breasts; they fall in with the immortal rhythm of life itself, which the others encounter and impugn.
It will be seen also that verse differs from prose as musical sounds from ordinary tones; and having so deep a ground in Nature, rhythmical speech will be sure to continue, in spite of objection and protest, were it, if possible, many times more energetic than that of Mr. Carlyle. But always the best prose has a certain rhythmic emphasis and cadence: in Milton's grander passages there is a symphony of organs, the bellows of the mighty North (one might say) filling their pipes; Goldsmith's flute still breathes through his essays; and in the ampler prose of Bacon there is the swell of a summer ocean, and you can half fancy you hear the long soft surge falling on the shore. Also in all good writing, as in good reading, the pauses suffer no slight; they are treated handsomely; and each sentence rounds gratefully and clearly into rest. Sometimes, indeed, an attempt is made to react in an illegitimate way this force of firm pauses, as in exaggerated French style, wherein the writer seems never to stride or to run, but always to jump like a frog.
Again, as reciprocal opposites, our two principles should be of equal dignity and value. To concede, however, the equality of rest with motion must, for an American, be not easy; and it is therefore in point to assert and illustrate this in particular. What better method of doing so than that of taking some one large instance in Nature, if such can be found, and allowing this, after fair inspection, to stand for all others? And, as it happens, just what we require is quite at hand;—the alternation of Day and Night, of sleep and waking, is so broad, obvious, and familiar, and so mingled with our human interests, that its two terms are easily subjected to extended and clear comparison; while also it deserves discussion upon its own account, apart from its relation to the general subject.
Sleep is now popularly known to be coextensive with Life,—inseparable from vital existence of whatever grade. The rotation of the earth is accordingly implied, as was happily suggested by Paley, in the constitution of every animal and every plant. It is quite evident, therefore, that this necessity was not laid upon, man through some inadvertence of Nature; on the contrary, this arrangement must be such as to her seemed altogether suitable, and, if suitable, economical. Eager men, however, avaricious of performance, do not always regard it with entire complacency. Especially have the saints been apt to set up a controversy with Nature in this particular, submitting with infinite unwillingness to the law by which they deem themselves, as it were, defrauded of life and activity in so large measure. In form, to be sure, their accusation lies solely against themselves; they reproach themselves with sleeping beyond need, sleeping for the mere luxury and delight of it; but the venial self-deception is quite obvious,—nothing plainer than that it is their necessity itself which is repugnant to them, and that their wills are blamed for not sufficiently withstanding and thwarting it. Pious William Law, for example, is unable to disparage sleep enough for his content. "The poorest, dullest refreshment of the body," he calls it,… "such a dull, stupid state of existence, that even among animals we despise them most which are most drowsy." You should therefore, so he urges, "begin the day in the spirit of renouncing sleep." Baxter, also,—at that moment a walking catalogue and epitome of all diseases,—thought himself guilty for all sleep he enjoyed beyond three hours a day. More's Utopians were to rise at very early hours, and attend scientific lectures before breakfast.
Ambition and cupidity, which, in their way, are no whit less earnest and self-sacrificing than sanctity, equally look upon sleep as a wasteful concession to bodily wants, and equally incline to limit such concession to its mere minimum. Commonplaces accordingly are perpetually circulating in the newspapers, especially in such as pretend to a didactic tone, wherein all persons are exhorted to early rising, to resolute abridgment of the hours of sleep, and the like. That Sir Walter Raleigh slept but five hours in twenty-four; that John Hunter, Frederick the Great, and Alexander von Humboldt slept but four; that the Duke of Wellington made it an invariable rule to "turn out" whenever he felt inclined to turn over, and John Wesley to arise upon his first awaking: instances such as these appear on parade with the regularity of militia troops at muster; and the precept duly follows,—"Whoso would not be insignificant, let him go and do likewise." "All great men have been early risers," says my newspaper.
Of late, indeed, a better knowledge of the laws of health, or perhaps only a keener sense of its value and its instability, begins to supersede these rash inculcations; and paragraphs due to some discreet Dr. Hall make the rounds of the press, in which we are reminded that early rising, in order to prove a benefit, rather than a source of mischief, must be duly matched with early going to bed. The one, we are told, will by no means answer without the other. As yet, however, this is urged upon hygienic grounds alone; it is a mere concession to the body, a bald necessity that we hampered mortals lie under; which necessity we are quite at liberty to regret and accuse, though we cannot with safety resist it. Sleep is still admitted to be a waste of time, though one with which Nature alone is chargeable. And I own, not without reluctance, that the great authority of Plato can be pleaded for this low view of its functions. In the "Laws" he enjoins a due measure thereof, but for the sake of health alone, and adds, that the sleeper is, for the time, of no more value than the dead. Clearly, mankind would sustain some loss of good sense, were all the dullards and fat-wits taken away; and Sancho Panza, with his hearty, "Blessings on the man that invented sleep!" here ekes out the scant wisdom of sages.
