In one of his earlier writings, the System of Transcendental Idealism; which we shall consider first of all, Schelling represented transcendental philosophy and natural philosophy as the two sides of scientific knowledge. Respecting the nature of the two, he expressly declared himself in this work, where he once more adopts a Fichtian starting-point: "All knowledge rests on the harmony of an objective with a subjective" In the common sense of the words this would be allowed; absolute unity, where the Notion and the reality are undistinguished in the perfected Idea, is the Absolute alone, or God; all else contains an element of discord between the objective and subjective. "We may give the name of nature to the entire objective content of our knowledge the entire subjective content, on the other hand, is called the ego or intelligence". They are in themselves identical and presupposed as identical. The relation of nature to intelligence is given by Schelling thus: "Now if all knowledge has two poles which mutually presuppose and demand one another, there must be two fundamental sciences, and it must be impossible to start from the one pole without being driven to the other". Thus nature is impelled to spirit, and spirit to nature; either may be given the first place, and both must come to pass. "If the objective is made the chief" we have the natural sciences as result, and; "the necessary tendency" the end, of all natural science thus is to pass from nature to intelligence. This is the meaning of the effort to connect natural phenomena with theory. The highest perfection of natural science would be the perfect spiritualization of all natural laws into laws of intuitive perception and thought."
