History of Modern Philosophy / From Nicolas of Cusa to the Present Time - Richard Falckenberg

"Nature is a priori" (everything individual in it is pre-determined by the whole, by the Idea of a nature in general); hence the forms of nature can be deduced from the concept of nature. The philosopher creates nature anew, he constructs it. Speculative physics considers nature as subject, becoming, productivity (not, like empirical science, as object, being, product), and for this purpose it needs, instead of individualizing reflection, an intuition directed to the whole. To this productive nature, as to the absolute ego of Fichte, are ascribed two opposite activities, one expansive or repulsive, and one attractive, and on these is based the universal law of polarity. The absolute productivity strives toward an infinite product, which it never attains, because apart from arrest no product exists. At definite points a check must be given it in order that something knowable may arise. Thus every product in nature is the result of a positive, centrifugal, accelerating, universalizing force, and a negative, limiting, retarding, individualizing one. The endlessness of the creative activity manifests itself in various ways: in the striving for development on the part of every product, in the preservation of the genus amid the disappearance of individuals, in the endlessness of the series of products. Nature's creative impulse is inexhaustible, it transcends every product. Qualities are points of arrest in the one universal force of nature; all nature is a connected development. Because of the opposition in the nature-ground between the stimulating and the retarding activity, the law of duality everywhere rules. To these two forces, however, still a third factor must be added as their copula, which determines the relation or measure of their connection. This is the source of the threefold division of the Philosophy of Nature. The magnet with its union of opposite polar forces is the type of all configuration in nature.

With Fichte's synthetic method and Herder's naturalistic principles Schelling combines Kantian ideas, especially Kant's dynamism (matter is a force-product),[1] and his view of the organic (organisms are self-productive beings, and are regarded by us as ends in themselves, because of the interaction between their members and the whole). The three organic functions sensibility, irritability, and reproduction, on the other hand, Schelling took from Kielmeyer, whose address On the Relations of the Organic Forces, 1793, excited great attention. The concept of life is dominant in Schelling's theory of nature. The organic is more original than the inorganic; the latter must be explained from the former; that which is dead must be considered as a product of departing life. No less erroneous than the theory of a magic vital force is the mechanical interpretation, which looks on life merely as a chemical phenomenon. The dead, mechanical and chemical, forces are merely the negative conditions of life; to them there must be added as a positive force a vital stimulus external to the individual, which continually rekindles the conflict between the opposing activities on which the vital process depends. Life consists, that is, in the perpetual prevention of the equilibrium which is the object of the chemical process. This constant disturbance proceeds from "universal nature," which, as the common principle of organic and inorganic nature, as that which determines them for each other, which founds a pre-established harmony between them, deserves the name of the world-soul. Schelling thus recognizes a threefold nature: organized, inorganic, and universal organizing (according to Harms, cosmical) nature, of which the two former arise from the third and are brought by it into connection and harmony. (As Schelling here takes an independent middle course between the mechanical explanation of life and the assumption of a specific vital force, so in all the burning physical questions of the time he seeks to rise above the contending parties by means of mediating solutions. Thus, in the question of "single or double electricity," he ranges himself neither on the side of Franklin nor on that of his opponents; in regard to the problem of light, endeavors to overcome the antithesis between Newton's emanation theory and the undulation theory of Euler; and, in his chapter on combustion, attacks the defenders of phlogiston as well as those who deny it).

[Footnote 1: Schelling terms his philosophy of nature dynamic atomism, since it posits pure intensities as the simple (atoms), from which qualities are to be explained.]

Schelling's philosophy of nature[1] proposes to itself three chief problems: the construction of general, indeterminate, homogeneous matter, with differences in density alone, of determinate, qualitatively differentiated matter and its phenomena of motion or the dynamical process, and of the organic process. For each of these departments of nature an original force in universal nature is assumed—gravity, light, and their copula, universal life. Gravity—this does not mean that which as the force of attraction falls within the view of sensation, for it is the union of attraction and repulsion—is the principle of corporeality, and produces in the visible world the different conditions of aggregation in solids, fluids, and gases. Light—this, too, is not to be confounded with actual light, of which it is the cause—is the principle of the soul (from it proceeds all intelligence, it is a spiritual potency, the "first subject" in nature), and produces in the visible world the dynamical processes magnetism, electricity, and chemism. The higher unity of gravity and light is the copula or life, the principle of the organic, of animated corporeality or the processes of growth and reproduction, irritability, and sensibility.

[Footnote 1: This is contained in the following treatises: Ideas for a Philosophy of Nature, 1797; On the World-soul, 1798; First Sketch of a System of the Philosophy of Nature, 1799; Universal Deduction of the Dynamical Process or the Categories of Physics (in the Zeitschrift für spekulative Physik) 1800. In the above exposition, however, the modified philosophy of nature of the second period has also been taken into account.]

General matter or the filling of space, arises from the co-operation of three forces: the centrifugal, which manifests itself as repulsion (first dimension), the centripetal, manifested as attraction (second dimension), and the synthesis of the two, manifested as gravity (third dimension). These forces are raised by light to a higher potency, and then make their appearance as the causes of the dynamical process or of the specific differences of matter. The linear function of magnetism is the condition of coherence; the surface force of electricity, the basis of the qualities perceivable by sense; the tri-dimensional force of the chemical process, in which the two former are united, produces the chemical qualities. Galvanism forms the transition to living nature, in which through the operation of the "copula" these three dynamical categories are raised to organic categories. To magnetism as the most general, and hence the lowest force, corresponds reproduction (the formative impulse, as nutrition, growth, and production, including the artistic impulse); electricity develops into irritability or excitability; the higher analogue to the chemical process as the most individual and highest stage is sensibility or the capacity of feeling. (Such at least is Schelling's doctrine after Steffens had convinced him of the higher dignity of that which is individual, whereas at first he had made sensibility parallel with magnetism, and reproduction with chemism, because the former two appear most seldom, and the latter most frequently. Electricity and irritability always maintained their intermediate position.) With the awakening of feeling nature has attained its goal—intelligence. As inorganic substances are distinguished only by relative degrees of repulsion and attraction, so the differentiation of organisms is conditioned by the relation of the three vital functions: in the lower forms reproduction predominates, then irritability gradually increases, while in the highest forms both of these are subordinated to sensibility. All species, however, are connected by a common life, all the stages are but arrests of the same fundamental force. This accentuation of the unity of nature, which establishes a certain kinship between Schelling's philosophy of nature and Darwinism, was a great idea, which deserves the thanks of posterity in spite of such defects as its often sportive, often heedlessly bold reasoning in details.

The parallelism of the potencies of nature, as we have developed it by leaving out of account the numerous differences between the various expositions of the Naturphilosophie, may be shown by a table:
