before, and joyfulness in the apparent though unreachable nearness and promise of them. But there are other modes in which infinity may be represented, which are confused by no associations of the kind, and which would, as being in mere matter, appear trivial and mean, but for their incalculable influence on the forms of all that we feel to be beautiful. The first of these

is the curvature of lines and surfaces, wherein it at first appears §14. The beauty futile to insist upon any resemblance or suggestion of curvature. of infinity, since there is certainly in our ordinary contemplation of it, no sensation of the kind. But I have repeated again and again that the ideas of beauty are instinctive, and that it is only upon consideration, and even then in doubtful and disputable way, that they appear in their typical character; neither do I intend at all to insist upon the particular meaning which they appear to myself to bear, but merely on their actual and demonstrable agreeableness, so that, in the present case, while I assert positively, and have no fear of being able to prove, that a curve of any kind is more beautiful.than a right line, I leave it to the reader to accept or not, as he pleases, that reason of its agreeableness, which is the only one that I can at all trace, namely, that every curve divides itself infinitely by its changes of direction.

15. How con

nature.

That all forms of acknowledged beauty are composed exclusively of curves will, I believe, be at once allowed; but that which there will be need more especially to prove, is the subtilty and constancy of curvature in all natural stant in external forms whatsoever. I believe that, except in crystals, in certain mountain forms admitted for the sake of sublimity or contrast, (as in the slope of debris,) in rays of light, in the levels of calm water and alluvial land, and in some few organic developments, there are no lines nor surfaces of nature without curvature, though as we before saw in clouds, more especially in their under lines towards the horizon, and in vast and extended plains, right lines are often suggested which are not actual. Without these we could not be sensible of the value of the contrasting curves, and while, therefore, for the most part, the eye is fed in natural forms with a grace of curvature which no hand nor instrument can follow, other means are provided to give beauty to those surfaces which are admitted for

contrast, as in water by its reflection of the gradations which it possesses not itself. In freshly-broken ground, which nature has not yet had time to model, in quarries and pits which are none of her cutting, in those convulsions and evidences of convulsion, of whose influence on ideal landscape I shall presently have occasion to speak, and generally in all ruin and disease, and interference of one order of being with another, (as in the cattle line of park trees,) the curves vanish, and violently opposed or broken and unmeaning lines take their place.

of gradation.

What curvature is to lines, gradation is to shades and colors. It is there infinity, and divides them into an infinite number of degrees. Absolutely, without gradation no natural surface can possibly be, except under circumstances of so rare $16. The beauty conjunction as to amount to a lusus naturæ ; for we have seen that few surfaces are without curvature, and every curved surface must be gradated by the nature of light, which is most intense when it impinges at the highest angle, and for the gradation of the few plane surfaces that exist, means are provided in local color, aerial perspective, reflected lights, etc., from which it is but barely conceivable that they should ever escape. Hence for instances of the complete absence of gradation we must look to man's work, or to his disease and decrepitude. Compare the gradated colors of the rainbow with the stripes of a target, and the gradual concentration of the youthful blood in the cheek with an abrupt patch of rouge, or with the sharply drawn veining of old age.

in Nature.

Gradation is so inseparable a quality of all natural shade and color that the eye refuses in art to understand anything as either, which appears without it, while on the other hand nearly all the gradations of nature are so subtile and be$17. How found tween degrees of tint so slightly separated, that no human hand can in any wise equal, or do anything more than suggest the idea of them. In proportion to the space over which gradation extends, and to its invisible subtilty, is its grandeur, and in proportion to its narrow limits and violent degrees, its vulgarity. In Correggio, it is morbid and vulgar in spite of its refinement of execution, because the eye is drawn to it, and it is made the most observable and characteristic part of the picture; whereas natural gradation is forever escaping

observation to that degree that the greater part of artists in working from nature see it not, (except in certain of its marked developments,) but either lay down such continuous lines and colors, as are both disagreeable and impossible, or, receiving the necessity of gradation as a principle instead of a fact, use it in violently exaggerated measure, and so lose both the dignity of their own work, and by the constant dwelling of their eyes upon exaggerations, their sensibility to that of the natural forms. So that we find the majority of painters divided between the two evil extremes of insufficiency and affectation, and only a few of the greatest men capable of making gradation constant and yet extended over enormous spaces and within degrees of narrow difference, as in the body of a high light.

sary in Art.

From the necessity of gradation results what is commonly given as a rule of art, though its authority as a rule obtains only from its being a fact of nature, that the extremes of high light § 18. How neces- and pure color, can exist only in points. The common rules respecting sixths and eighths, held concerning light and shade, are entirely absurd and conventional; according to the subject and the effect of light, the greater part of the picture will be or ought to be light or dark; but that principle which is not conventional, is that of all light, however high, there is some part that is higher than the rest, and that of all color, however pure, there is some part that is purer than the rest, and that generally of all shade, however deep, there is some part deeper than the rest, though this last fact is frequently sacrificed in art, owing to the narrowness of its means. But on the right gradation or focussing of light and color depends in great measure, the value of both. Of this, I have spoken sufficiently in pointing out the singular constancy of it in the works of Turner. Part II. Sect. II. Chap. II. § 17. And it is generally to be observed that even raw and valueless color, if rightly and subtilely gradated will in some measure stand for light, and that the most transparent and perfect hue will be in some measure unsatisfactory, if entirely unvaried. believe the early skies of Raffaelle owe their luminousness more to their untraceable and subtile gradation than to inherent quality of hue.

Such are the expressions of infinity which we find in crea

tion, of which the importance is to be estimated, rather by their frequency than their distinctness. Let, however, the reader bear constantly in mind that I insist not on his rightly implied accepting any interpretation of mine, but only on his dwelling so long on those objects, which he perceives to be beautiful, as to determine whether the qualities to which I trace their beauty, be necessarily there or no. Farther expressions of infinity there are in the mystery of nature, and in some measure in her vastness, but these are dependent on our own imperfections, and therefore, though they produce sublimity, they are unconnected with beauty. For that which we foolishly call vastness is, rightly considered, not more wonderful, not more impressive, than that which we insolently call littleness, and the infinity of God is not mysterious, it is only unfathomable, not concealed, but incomprehensible it is a clear infinity, the darkness of the pure unsearchable sea.

CHAPTER VI.

OF UNITY, OR THE TYPE OF THE DIVINE COMPREHENSIVENESS.

$1 The general

vine Unity.

"ALL things," says Hooker, " (God only excepted,) besides the nature which they have in themselves, receive externally some perfection from other things." Hence the appearance of separation or isolation in anything, and of self-dependconception of di- ence, is an appearance of imperfection: and all appearances of connection and brotherhood are pleasant and right, both as significative of perfection in the things united, and as typical of that Unity which we attribute to God, and of which our true conception is rightly explained and limited by Dr. Brown in his XCII. lecture; that Unity which consists not in his own singleness or separation, but in the necessity of his inherence in all things that be, without which no creature of any kind could hold existence for a moment. Which necessity of Divine essence I think it better to speak of as comprehensiveness, than as unity, because unity is often understood in the sense of oneness or singleness, instead of universality, whereas the only Unity which by any means can become grateful or an object of hope to men, and whose types therefore in material things can be beautiful, is that on which turned the last words and prayer of Christ before his crossing of the Kidron brook. "Neither pray I for these alone, but for them also which shall believe on me through their word. That they all may be one, as thou, Father, art in me, and I in thee."

And so there is not any matter, nor any spirit, nor any creature, but it is capable of an unity of some kind with other creatures, and in that unity is its perfection and theirs, and a pleasure also for the beholding of all other creatures that can behold. So the unity of spirits is partly in their sympathy, and partly in their giving and taking, and always in their love; and these are their delight
