With regard to works in all the branches of the fine arts, I may remark that the pleasure arising from novelty must of course be allowed its due place and weight. This pleasure consists in the identity of two opposite elements, that is to say--sameness and variety. If in the midst of the variety there be not some fixed object for the attention, the unceasing succession of the variety will prevent the mind from observing the difference of the individual objects; and the only thing remaining will be the succession, which will then produce precisely the same effect as sameness. This we experience when we let the trees or hedges pass before the fixed eye during a rapid movement in a carriage, or on the other hand, when we suffer a file of soldiers or ranks of men in procession to go on before us without resting the eye on any one in particular. In order to derive pleasure from the occupation of the mind, the principle of unity must always be present, so that in the midst of the multeity the centripetal force be never suspended, nor the sense be fatigued by the predominance of the centrifugal force. This unity in multeity I have elsewhere stated as the principle of beauty. It is equally the source of pleasure in variety, and in fact a higher term including both. What is the seclusive or distinguishing term between them? Remember that there is a difference between form as proceeding, and shape as superinduced;--the latter is either the death or the imprisonment of the thing;--the former is its self-witnessing and self-effected sphere of agency. Art would or should be the abridgment of nature. Now the fulness of nature is without character, as water is purest when without taste, smell, or colour; but this is the highest, the apex only,--it is not the whole. The object of art is to give the whole 'ad hominem'; hence each step of nature hath its ideal, and hence the possibility of a climax up to the perfect form of a harmonized chaos. To the idea of life victory or strife is necessary; as virtue consists not simply in the absence of vices, but in the overcoming of them. So it is in beauty. The sight of what is subordinated and conquered heightens the strength and the pleasure; and this should be exhibited by the artist either inclusively in his figure, or else out of it and beside it to act by way of supplement and contrast. And with a view to this, remark the seeming identity of body and mind in infants, and thence the loveliness of the former; the commencing separation in boyhood, and the struggle of equilibrium in youth: thence onward the body is first simply indifferent; then demanding the translucency of the mind not to be worse than indifferent; and finally all that presents the body as body becoming almost of an excremental nature.
