(a) Relationship of Substantiality.
150.] The necessary is in itself an absolute correlation of elements, i.e. the process developed (in the preceding paragraphs), in which the correlation also suspends itself to absolute identity.
In its immediate form it is the relationship of Substance and Accident. The absolute self-identity of this relationship is Substance as such, which as necessity gives the negative to this form of inwardness, and thus invests itself with actuality, but which also gives the negative to this outward thing. In this negativity, the actual, as immediate, is only an accidental which through this bare possibility passes over into another actuality. This transition is the identity of substance, regarded as form-activity (§§ 148, 149).
151.] Substance is accordingly the totality of the Accidents, revealing itself in them as their absolute negativity, (that is to say, as absolute power,) and at the same time as the wealth of all content. This content however is nothing but that very revelation, since the character (being reflected in itself to make content) is only a passing stage of the form which passes away in the power of substance. Substantiality is the absolute form-activity and the power of necessity: all content is but a vanishing element which merely belongs to this process, where there is an absolute revulsion of form and content into one another.
In the history of philosophy we meet with Substance as the principle of Spinoza's system. On the import and value of that much-praised and no less decried philosophy there has been great misunderstanding and a deal of talking since the days of Spinoza. The atheism and, as a further charge, the pantheism of the system has formed the commonest ground of accusation. These cries arise because of Spinoza's conception of God as substance, and substance only. What we are to think of this charge follows, in the first instance, from the place which substance takes in the system of the logical idea. Though an essential stage in the evolution of the idea, substance is not the same with absolute Idea, but the idea under the still limited form of necessity. It is true that God is necessity, or, as we may also put it, that He is the absolute Thing: He is however no less the absolute Person. That He is the absolute Person however is a point which the philosophy of Spinoza never reached: and on that side it falls short of the true notion of God which forms the content of religious consciousness in Christianity. Spinoza was by descent a Jew; and it is upon the whole the Oriental way of seeing things, according to which the nature of the finite world seems frail and transient, that has found its intellectual expression in his system. This Oriental view of the unity of substance certainly gives the basis for all real further development. Still it is not the final idea. It is marked by the absence of the principle of the Western World, the principle of individuality, which first appeared under a philosophic shape, contemporaneously with Spinoza, in the Monadology of Leibnitz.
From this point we glance back to the alleged atheism of Spinoza. The charge will be seen to be unfounded if we remember that his system, instead of denying God, rather recognises that He alone really is. Nor can it be maintained that the God of Spinoza, although he is described as alone true, is not the true God, and therefore as good as no God. If that were a just charge, it would only prove that all other systems, where speculation has not gone beyond a subordinate stage of the idea,—that the Jews and Mohammedans who know God only as the Lord,—and that even the many Christians for whom God is merely the most high, unknowable, and transcendent being, are as much atheists as Spinoza. The so-called atheism of Spinoza is merely an exaggeration of the fact that he defrauds the principle of difference or finitude of its due. Hence his system, as it holds that there is properly speaking no world, at any rate that the world has no positive being, should rather be styled Acosmism, These considerations will also show what is to be said of the charge of Pantheism. If Pantheism means, as it often does, the doctrine which takes finite things in their finitude and in the complex of them to be God, we must acquit the system of Spinoza of the crime of Pantheism. For in that system, finite things and the world as a whole are denied all truth. On the other hand, the philosophy which is Acosmism is for that reason certainly pantheistic.
The shortcoming thus acknowledged to attach to the content turns out at the same time to be a shortcoming in respect of form. Spinoza puts substance at the head of his system, and defines it to be the unity of thought and extension, without demonstrating how he gets to this distinction, or how he traces it back to the unity of substance. The further treatment of the subject proceeds in what is called the mathematical method. Definitions and axioms are first laid down: after them comes a series of theorems, which are proved by an analytical reduction of them to these unproved postulates. Although the system of Spinoza, and that even by those who altogether reject its contents and results, is praised for the strict sequence of its method, such unqualified praise of the form is as little justified as an unqualified rejection of the content. The defect of the content is that the form is not known as immanent in it, and therefore only approaches it as an outer and subjective form. As intuitively accepted by Spinoza without a previous mediation by dialectic, Substance, as the universal negative power, is as it were a dark shapeless abyss which engulfs all definite content as radically null, and produces from itself nothing that has a positive subsistence of its own.
152.] At the stage, where substance, as absolute power, is the self-relating power (itself a merely inner possibility) which thus determines itself to accidentality,—from which power the externality it thereby creates is distinguished—necessity is a correlation strictly so called, just as in the first form of necessity, it is substance. This is the correlation of Causality.
(b) Relationship of Causality.
153.] Substance is Cause, in so far as substance reflects into self as against its passage into accidentality and so stands as the primary fact, but again no less suspends this reflection-into-self (its bare possibility), lays itself down as the negative of itself, and thus produces an Effect, an actuality, which, though so far only assumed as a sequence, is through the process that effectuates it at the same time necessary.
