ceptions be also diversified: number without variety is not sufficient to constitute an agreeable train. In comparing a few objects, uni. formity is pleasant; but the frequent reiteration of uniform objects becomes unpleasant: one tires of a scene that is not diversified; and soon feels a sort of unnatural restraint when confined within a par. row range, whether occasioned by a retarded succession, or by 100 great uniformity. An excess in variety is, on the other hand, fatiguing : which is felt even in a train of related perceptions; much more of unrelated perceptions, which gain not admittance without effort: the effort, it is true, is scarcely perceptible in a single instance; but by frequent reiteration it becomes exceedingly painful. Whatever be the cause, the fact is certain, that a man never finds himself more at ease, than when his perceptions succeed each other with a certain degree, not only of velocity, but also of variety. The pleasure that arises from a train of connected ideas, is remarkable in a reverie ; especially where the imagination interposes, and is active in coining new ideas, which is done with wonderful facility. one must be sensible, that the serenity and ease of the mind in that state, makes a great part of the enjoyment. The case is different where external objects enter into the train ; for these, making their appearance without order, and without connection save that of con. tiguity, form a train of perceptions that may be extremely uniform or extremely diversified; which, for opposite reasons, are both of them painful.

To alter, by an act of will. that degree of variety which nature requires, is not less painful, than to alter that degree of velocity which it requires. Contemplation, when the mind is long attached to one subject, becomes painful by restraining the free range of perception : curiosity, and the prospect of useful discoveries, may fortify one to bear that pain : but it is deeply felt by the bulk of mankind, and produces in them aversion to all abstract sciences. In any profession or calling, a train of operation that is simple and reiterated without intromission, makes the operator languish, and lose vigor: he complains neither of too greai labor, nor of too little action; but regrets the want of variety, and the being obliged to do the same thing over and over : where the operation is sufficiently varied, the mind retains its vigor, and is pleased with its condition. Actions again create uneasiness when excessive in number or variety, though in every other respect pleasant: thus a throng of business in law, in physic, or in traffic, distresses and distracts the mind, unless where a habit of application is acquired by long and constant exercise: the excessive variety is the distressing circumstance; and the mmd suffers grievously by being kept constantly upon the stretch.

With relation to involuntary causes disturbing that degree of variety which nature requires, a slight pain affecting one part of the body without variation, becomes, by its constancy and long duration, almost insupportable; the patient, sensible that the pain is not in: creased in degree, complains of its constancy more than of its severity, of its engrossing his whole thoughts, and admitting no other object. A shifting pain is more tolerable, because change of place

contributes to variety: and an intermitting pain, suffering other ob jects to intervene, still more so. Again, any single color or sound often returning becomes unpleasant; as may be observed in viewing a train of similar apartments in a great house painted with the same color, and in hearing the prolonged tollings of a bell. Color and sound varied within certain limits, though without any order, are pleasant ; witness the various colors of plants and flowers in a field, and the various notes of birds in a thicket : increase the number of variety, and the feeling becomes unpleasant; thus a great variety of colors, crowded upon a small canvas or in quick succession, create an uneasy feelin;, which is prevented by putting the colors at a greater distance from each other, either of place or of time. A number of voices in a crowded assembly, a number of animals collected in a market, produce an unpleasant feeling; though a few of them together, or all of them in a moderate succession, would be pleasant.

And because of the same excess in variety, a number of pains felt in different parts of the body, at the same instant or in a rapid succession, are an exquisite torture.

The pleasure or pain resulting from a train of perceptions in different circumstances, are a beautiful contrivance of nature for valuable purposes. But being sensible, that the mind, inflamed with speculations so highly interesting, is beyond measure disposed to conviction; I shall be watchful to admit no argument nor remark, but what appears solidly founded; and with that caution I proceed to unfold these purposes. It is occasionally observed above, that persons of a phlegmatic temperament, having a sluggish train of perceptions are indisposed to action; and that activity constantly accompanies a brisk flow of perceptions. To ascertain that fact, a man need not go abroad for experiments: reflecting on things passing in his own mind, he will find, that a brisk circulation of thought constantly prompts him to action; and that he is averse to action when his perceptions languish in their course. But as man by nature is formed for action, and must be active in order to be happy, nature has kindly provided against indolence, by annexing pleasure to a moderate course of perceptions, and by making any remarkable retardation painful. A slow course of perceptions is attended with another bad effect: man, in a few capital cases, is governed by propensity or instinct; but in matters that admit deliberation and choice, reason is assigned him for a guide : now, as reasoning requires often a great compass of ideas, their succession ought to be so quick as readily to furnish every motive that may be necessary for mature deliberation ; in a languid succession, motives will often occur after action is comme

menced, when it is too late to retreat.

Nature has guarded man, her favorite, against a succession too rapid, no less carefully than against one too slow: both are equally painful, though the pain is not the same in both. Many are the good effects of that contrivance. In the first place, as the exertion of bodily faculties is by certain painful sensations confined within proper limits, Nature is equally provident with respect to the nobler faculties of the mind the pain of an accelerated course of perceptions,

is Nature's admonition to relax our pace, and to admit a more gentle exertion of thought. Another valuable purpose is discovered upon reflecting in what manner objects are imprinted on the mind: to give the memory firm hold of an external object, time is required, even where attention is the greatest; and a moderate degree of attention, which is the common case, must be continued still longer to produce the same effect. A rapid succession, accordingly, must prevent objects from making an impression so deep as to be of real service in life; and Nature, for the sake of memory, has, by a painful feeling, guarded against a rapid succession. But a still more valuable purpose is answered by the contrivance; as, on the one hand, a sluggish course of perceptions indisposes to action; so, on the other, a course too rapid impels to rash and precipitant action: prudent conduct is the child of deliberation and clear conception, for which there is no place in a rapid course of thought. Nature therefore, taking measures for prudent conduct, has guarded us effectually from precipitancy of thought; by making it painful.

Nature not only provides against a succession too slow or too quick, but makes the middle course extremely pleasant. Nor is that course confined within narrow bounds: every man can naturally, without pain, accelerate or retard, in some degree, the rate of his perceptions. And he can do it in a still greater degree by the force of habit: a habit of contemplation annihilates the pain of a retarded course of perceptions; and a busy life, after long practice, makes acceleration pleasant.

Concerning the final cause of our taste for variety, it will be considered, that human affairs, complex by variety as well as number, require the distributing of our attention and activity in measure and proportion. Nature therefore, to secure a just distribution corresponding to the variety of human aflairs, has made too great uniformity or too great variety in the course of perceptions, equally unpleasant: and indeed, were we addicted to either extreme, our internal constitution would be ill suited to our external circumstances. At the same time, where great uniformity of operation is required, as in several manufactures, or great variety, as in law or physic, Nature, attentive to all our wants, has also provided for these cases, by implanting in the breast of every person, an efficacious principle that leads to habit: an obstinate perseverance in the same occupation, relieves from the pain of excessive uniformity; and the like perseverance in a quick circulation of different occupations, relieves from the pain of excessive variety. And thus we come to take delight in several occupations, that by nature, without habit, are not a little disgustful.

A middle rate also in the train of perceptions between uniformity and variety, is no less pleasant than between quickness and slowness. The mind of man, so framed, is wonderfully adapted to the course of human affairs, which are continually changing, but not without connection: it is equally adapted to the acquisition of knowledge, which results chiefly from discovering resemblances among differing objects, and differences among resembling objects: such occupation,

even abstracting from the knowledge we acquire, is in itself delightful, by preserving a middle rate between too great uniformity and too great variety.

We are now arrived at the chief purpose of the present chapter which is to consider uniformity and variety with relation to the fine arts, in order to discover, if we can, when it is that the one ought 10 prevail, and when the other. And the knowledge we have obtained, will even at first view suggest a general observation, that in every work of art, it must be agreeable, to find that degree of variety which corresponds to the natural course of our perceptions; and that an excess in variety or in uniformity must be disagreeable, by varying that natural course. For that reason, works of art admit more or less variety according to the nature of the subject: in a picture of an interesting event that strongly attaches the spectator to a single object, the mind relishes not a multiplicity of figures nor of ornaments: a picture representing a gay subject, admits great variety of figures and ornaments; because these are agreeable to the mind in a cheerful tone. The same observation is applicable to poetry and to music.

It must at the same time be remarked, that one can bear a greater variety of natural objects, than of objects in a picture; and a greater variety in a picture, than in a description. A real object presented to view, makes an impression more readily than when represented in colors, and much more readily than when represented in words. Hence it is, that the profuse variety of objects in some natural landscapes, neither breeds confusion nor fatigue: and for the same reason, there is place for greater variety of ornament in a picture than in a poem. A picture, however, like a building, ought to be so simple as to be comprehended in one view. Whether every one of Le Brun's pictures of Alexander's history will stand this test, is submitted to judges.

From these general observations, I proceed to particulars. In works exposed continually to public view, variety ought to be studied. It is a rule, accordingly, in sculpture, to contrast the different limbs of a statue, in order to give it all the variety possible. Though the cone, in a single view, be more beautiful than the pyramid; yet a pyramidal steeple, because of its variety, is justly preferred. For the same reason, the oval is preferred before the circle; and painters, in copying buildings or any regular work, give an air of variety, by representing the subject in an angular view: we are pleased with the variety, without losing sight of the regularity. In a landscape representing animals, those especially of the same kind, contrast ought to prevail: to draw one sleeping, another awake; one sitting, another in motion; one moving toward the spectator, another from him, is the life of such a performance.

In every sort of writing intended for amusement, variety is necessary in proportion to the length of the work. Want of variety is sensibly felt in Davila's history of the civil wars of France: the events are indeed important and various; but the reader languishes by a tiresome monotony of character, every person engaged being

figured a consummate politician, governed by interest only. It is hard to say, whether Ovid disgusts more by too great variety, or too great uniformity. His stories are all of the same kind, concluding invariably with the transformation of one being into another; and so far he is tiresome by excess in uniformity: he is not less fatiguing by excess in variety, hurrying his reader incessantly from story to story. Ariosto is still more fatiguing than Ovid, by exceeding the just bounds of variety. Not satisfied, like Ovid, with a succession in his stories, he distracts the reader, by jumbling together a multitude of them without any connection. Nor is the Orlando Furioso less tiresome by its uniformity than the Metamorphoses, though in a different manner. After a story is brought to a crisis, the reader, intent on the catastrophe, is suddenly snatched away to a new story, which makes no impression so long as the mind is occupied with the former. This tantalizing method, from which the author never once swerves during the course of a long work, besides its uniformity, has another bad effect: it prevents that sympathy, which is raised by an interesting event when the reader meets with no interruption.

The emotions produced by our perceptions in a train, have been little considered, and less understood; the subject therefore required an elaborate discussion. It may surprise some readers to find variety treated as only contributing to make a train of perceptions pleasant, when it is commonly held to be a necessary ingredient in beauty of whatever kind; according to the definition, " That beauty consists in uniformity amid variety.” But, after the subject is explained and illustrated as above, I presume it will be evident, that this definition, however applicable to one or other species, is far from being just with respect to beauty in general: variety contributes no share to the beauty of a moral action, nor of a mathematical theorem: and numberless are the beautiful objects of sight that have little or no variety in them: a globe, the most uniform of all figures, is of all the most beautiful; and a square, though more beautiful than a trapezium, has less variety in its constituent parts. The foregoing definition, which at best is but obscurely expressed, is only applicable to a number of objects in a group or in succession, among which, indeed, a due mixture of uniformity and variety is always agreeable, provided the particular objects, separately considered, be in any degree beautiful, for uniformity amid variety among ugly objects, affords no pleasure. This circumstance is totally omitted in the definition; and indeed to have mentioned it, would, at the very first glance, have shown the definition to be imperfect: for to define beauty as arising from beautiful objects blended together in a due proportion of uniformity and variety, would be too gross to pass cur. rent: as nothing can be more gross, than to employ in a definition the very term that is to be explained.
