Beauty exists also in matter itself, abstraction being made of its form; it consists, then, in the unity and _simplicity_ which constitutes _purity_. Such is the purity of the sky and of the atmosphere, the purity of colors and of sounds; that of certain substances—of precious stones, of gold, and of the diamond. Pure and simple colors are also the most agreeable. After having described the beautiful in nature, in order that the necessity of a beauty more exalted and more ideal shall be comprehended, Hegel sets forth the _imperfections_ of real beauty. He begins with animal life, which is the most elevated point we have reached, and he dwells upon the characteristics and causes of that imperfection. Thus, first in the animal, although the organism is more perfect than that of the plant, what we see is not the central point of life; the special seat of the operations of the force which animates the whole, remains concealed from us. We see only the outlines of the external form, covered with hairs, scales, feathers, skin; secondly, the human body, it is true, exhibits more beautiful proportions, and a more perfect form, because in it, life and sensibility are everywhere manifested—in the color, the flesh, the freer movements, nobler attitudes, &c. Yet here, besides the imperfections in details, the sensibility does not appear equally distributed. Certain parts are appropriated to animal functions, and exhibit their destination in their form. Further, individuals in nature, placed as they are under a dependence upon external causes, and under the influence of the elements, are under the dominion of necessity and want. Under the continual action of these causes, physical being is exposed to losing the fulness of its forms and the flower of its beauty; rarely do these causes permit it to attain to its complete, free and regular development. The human body is placed under a like dependence upon external agents. If we pass from the physical to the moral world, that dependence appears still more clearly. Everywhere there is manifested diversity, and opposition of tendencies and interests. The individual, in the plenitude of his life and beauty, cannot preserve the appearance of a free force. Each individual being is limited and particularized in his excellence. His life flows in a narrow circle of space and time; he belongs to a determinate species; his type is given, his form defined, and the conditions of his development fixed. The human body itself offers, in respect to beauty, a progression of forms dependent on the diversity of races. Then come hereditary qualities, the peculiarities which are due to temperament, profession, age, and sex. All these causes alter and disfigure the purest and most perfect primitive type.
