Secondly, as to nature. We must imitate nature! yes, but what in nature,--all and every thing? No, the beautiful in nature. And what then is the beautiful? What is beauty? It is, in the abstract, the unity of the manifold, the coalescence of the diverse; in the concrete, it is the union of the shapely ('formosum') with the vital. In the dead organic it depends on regularity of form, the first and lowest species of which is the triangle with all its modifications, as in crystals, architecture, &c.; in the living organic it is not mere regularity of form, which would produce a sense of formality; neither is it subservient to any thing beside itself. It may be present in a disagreeable object, in which the proportion of the parts constitutes a whole; it does not arise from association, as the agreeable does, but sometimes lies in the rupture of association; it is not different to different individuals and nations, as has been said, nor is it connected with the ideas of the good, or the fit, or the useful. The sense of beauty is intuitive, and beauty itself is all that inspires pleasure without, and aloof from, and even contrarily to, interest. If the artist copies the mere nature, the 'natura naturata', what idle rivalry? If he proceeds only from a given form, which is supposed to answer to the notion of beauty, what an emptiness, what an unreality there always is in his productions, as in Cipriani's pictures! Believe me, you must master the essence, the 'natura naturans', which presupposes a bond between nature in the higher sense and the soul of man. The wisdom in nature is distinguished from that in man by the co-instantaneity of the plan and the execution; the thought and the product are one, or are given at once; but there is no reflex act, and hence there is no moral responsibility. In man there is reflexion, freedom, and choice; he is, therefore, the head of the visible creation. In the objects of nature are presented, as in a mirror, all the possible elements, steps, and processes of intellect antecedent to consciousness, and therefore to the full development of the intelligential act; and man's mind is the very focus of all the rays of intellect which are scattered throughout the images of nature. Now so to place these images, totalized, and fitted to the limits of the human mind, as to elicit from, and to superinduce upon, the forms themselves the moral reflexions to which they approximate, to make the external internal, the internal external, to make nature thought, and thought nature,--this is the mystery of genius in the Fine Arts. Dare I add that the genius must act on the feeling, that body is but a striving to become mind,--that it is mind in its essence!
