§ 36. History follows the thread of events; it is pragmatic so far as it deduces them in accordance with the law of motivation, a law that determines the self-manifesting will wherever it is enlightened by knowledge. At the lowest grades of its objectivity, where it still acts without knowledge, natural science, in the form of etiology, treats of the laws of the changes of its phenomena, and, in the form of morphology, of what is permanent in them. This almost endless task is lightened by the aid of concepts, which comprehend what is general in order that we may deduce what is particular from it. Lastly, mathematics treats of the mere forms, time and space, in which the Ideas, broken up into multiplicity, appear for the knowledge of the subject as individual. All these, of which the common name is science, proceed according to the principle of sufficient reason in its different forms, and their theme is always the phenomenon, its laws, connections, and the relations which result from them. But what kind of knowledge is concerned with that which is outside and independent of all relations, that which alone is really essential to the world, the true content of its phenomena, that which is subject to no change, and therefore is known with equal truth for all time, in a word, the _Ideas_, which are the direct and adequate objectivity of the thing in-itself, the will? We answer, _Art_, the work of genius. It repeats or reproduces the eternal Ideas grasped through pure contemplation, the essential and abiding in all the phenomena of the world; and according to what the material is in which it reproduces, it is sculpture or painting, poetry or music. Its one source is the knowledge of Ideas; its one aim the communication of this knowledge. While science, following the unresting and inconstant stream of the fourfold forms of reason and consequent, with each end attained sees further, and can never reach a final goal nor attain full satisfaction, any more than by running we can reach the place where the clouds touch the horizon; art, on the contrary, is everywhere at its goal. For it plucks the object of its contemplation out of the stream of the world’s course, and has it isolated before it. And this particular thing, which in that stream was a small perishing part, becomes to art the representative of the whole, an equivalent of the endless multitude in space and time. It therefore pauses at this particular thing; the course of time stops; the relations vanish for it; only the essential, the Idea, is its object. We may, therefore, accurately define it as the _way of viewing things independent of the principle of sufficient reason_, in opposition to the way of viewing them which proceeds in accordance with that principle, and which is the method of experience and of science. This last method of considering things may be compared to a line infinitely extended in a horizontal direction, and the former to a vertical line which cuts it at any point.
