To achieve the common origin of "I" and nature, Schelling takes a new approach to the philosophy of nature; demonstrating the falsity of dualism between "I" and nature and showing how nature cannot be reduced to a mechanistic series of causes and effects. By integrating Leibniz's principle of inner purposiveness, Spinoza's monism, and the Kantian concept of teleology, he interprets an organic idea of nature as a totality and founds "I" on the ground of this organic nature. Schelling turns to Leibniz's vitalistic philosophy for presents a self-organizing scheme of nature, and he uses the intensive doctrine of substance to overcome the dualism of modern philosophy. In this view, the parts are to be deduced, in a purely analytic way from the whole, and each unit must include an infinite plurality, so the difference between subject and object is in degree, not in type; Nature is all alive, and no real object is entirely inorganic but is only in a lower degree of organic. In Schilling's point of view, the highest degree of organization of the infinite is the creativity of the artist, who is the culmination of all the organic forces of nature. The main question of this essay is about the fundamental role of Schelling's organic interpretation in his aesthetic essence. in this regard, while the impact of Leibniz's vitalistic approach is analyzed, the reinforcement of the activity of "I" in Schilling's system of thought is examined.
