When these two beauties concur in any object, it appears delightful. Every member of the human body possesses both in a high degree. The slender make of a horse destined for running, pleases every taste; partly from symmetry, and partly from utility.
The beauty of utility, being proportioned accurately to the degree of utility, requires no illustration. But intrinsic beauty, so complex as I have said, cannot be handled distinctly without being analized into its constituent parts. If a tree be beautiful by means of its colour, its figure, its size, its motion, it is in reality possessed of so many different beauties, which ought to be examined separately, in order to have a clear notion of the whole. The beauty of colour is too familiar to need explanation. The beauty of figure requires an accurate discussion, for in it many circumstances are involved. When any portion of matter is viewed as a whole, the beauty of its figure arises from regularity and simplicity. Viewing the parts with relation to each other, uniformity, proportion, and order, contribute to its beauty. The beauty of motion deserves a chapter by itself; and another chapter is destined for grandeur, being distinguishable from beauty in a strict sense. For the definitions of regularity, uniformity, proportion, and order, if thought necessary, I remit my reader to the appendix at the end of the book. Upon simplicity I must make a few cursory observations, such as may be of use in examining the beauty of single objects.
A multitude of objects crowding into the mind at once, disturb the attention, and pass without making any impression, or any lasting impression. In a group, no single object makes the figure it would do apart, when it occupies the whole attention[52]. For the same reason, even a single object, when it divides the attention by the multiplicity of its parts, equals not, in strength of impression, a more simple object comprehended in a single view. Parts extremely complex must be considered in portions successively; and a number of impressions in succession, which cannot unite because not simultaneous, never touch the mind like one entire impression made as it were at one stroke. This justifies simplicity in works of art, as opposed to complicated circumstances and crowded ornaments. There is an additional reason for simplicity, in works that make an impression of dignity or elevation. The mind attached to beauties of a high rank, cannot descend to inferior beauties. And yet, notwithstanding these reasons, we find profuse decoration prevailing in works of art. But this is no argument against simplicity, For authors and architects who cannot reach the higher beauties, endeavour to supply their want of genius by dealing in those that are inferior. In all ages, the best writers and artists have been governed by a taste for simplicity.
