It is true that Leibnitz has a reply to the above question: “God does not will what is evil; evil comes only indirectly into the results” (blind), “because oftentimes the greater good could not be achieved if evils were not present. Therefore they are means to a good end.” But why does not God employ other means? They are always external, not in and for themselves. “A moral evil may not be regarded as a means, nor must we, as the apostle says, do evil that good may come; yet it has often the relation of a conditio sine qua non of the good. Evil is in God only the object of a permissive will (voluntatis permissivæ);” but everything that is wrong would be such. “God has therefore among the objects of His will the best possible as the ultimate object, but the good as a matter of choice (qualemcunque), also as subordinate; and things indifferent and evils often as means. Evil is, however, an object of His will only as the condition of something otherwise necessary (rei alioqui debitæ), which without it could not exist; in which sense Christ said it must needs be that offences come.”[265]
In a general sense we are satisfied with the answer: “In accordance with the wisdom of God we must accept it as a fact that the laws of nature are the best possible,” but this answer does not suffice for a definite question. What one wishes to know is the goodness of this or that particular law; and to that no answer is given. If, for example, it is said that “The law of falling bodies, in which the relation of time and space is the square, is the best possible,” one might employ, as far as mathematics are concerned, any other power whatever. When Leibnitz answers: “God made it so,” this is no answer at all. We wish to know the definite reason of this law; such general determinations sound pious, but are not satisfying.
γ. He goes on to say that the sufficient reason has reference to the representation of the monads. The principles of things are monads, of which each is for itself, without having influence on the others. If now the Monad of monads, God, is the absolute substance, and individual monads are created through His will, their substantiality comes to an end. There is therefore a contradiction present, which remains unsolved in itself—that is between the one substantial monad and the many monads for which independence is claimed, because their essence consists in their standing in no relation to one another. Yet at the same time, in order to show the harmony that exists in the world, Leibnitz understands the relation of monads to monads more generally as the unity of contrasted existences, namely of soul and body. This unity he represents as a relation without difference, and notionless, i.e. as a pre-established harmony.[266] Leibnitz uses here the illustration of two clocks, which are set to the same hour, and keep the same time;[267] in the same way the movement of the kingdom of thought goes on, determined in accordance with ends, and the movement onward of the corporeal kingdom which corresponds with it, proceeds according to a general causal connection.[268] The case is the same as with Spinoza, that these two sides of the universe have no connection with each other, the one does not influence the other, but both are entirely indifferent to one another; it is really the differentiating relation of the Notion that is lacking. In abstract thought that is without Notion, that determination now receives the form of simplicity, of implicitude, of indifference with regard to what is other, of a self-reflection that has no movement: in this way red in the abstract is in a position of indifference as regards blue, &c. Here, as before, Leibnitz forsakes his principle of individuation; it has only the sense of being exclusively one, and of not reaching to and including what is other; or it is only a unity of the popular conception, not the Notion of unity. The soul has thus a series of conceptions and ideas which are developed from within it, and this series is from the very first placed within the soul at its creation, i.e. the soul is in all immediacy this implicit determination; determination is, however, not implicit, but the reflected unfolding of this determination in the ordinary conception is its outward existence. Parallel with this series of differentiated conceptions, there now runs a series of motions of the body, or of what is external to the soul.[269] Both are essential moments of reality; they are mutually indifferent, but they have also an essential relation of difference.
Since now every monad, as shut up within itself, has no influence upon the body and its movements, and yet the infinite multitude of their atoms correspond with one another, Leibnitz places this harmony in God; a better definition of the relation and the activity of the Monad of monads is therefore that it is what pre-establishes harmony in the changes of the monads.[270] God is the sufficient reason, the cause of this correspondence; He has so arranged the multitude of atoms that the original changes which are developed within one monad correspond with the changes of the others. The pre-established harmony is to be thought of somewhat in this style; when a dog gets a beating, the pain develops itself in him, in like fashion the beating develops itself in itself, and so does the person who administers the beating: their determinations all correspond with one another, and that not by means of their objective connection, since each is independent.[271] The principle of the harmony among the monads does not consequently belong to them, but it is in God, who for that very reason is the Monad of monads, their absolute unity. We saw from the beginning how Leibnitz arrived at this conception. Each monad is really possessed of the power of representation, and is as such a representation of the universe, therefore implicitly the totality of the whole world. But at the same time this representation is not in consciousness; the naked monad is implicitly the universe, and difference is the development of this totality in it.[272] What develops itself therein is at the same time in harmony with all other developments; all is one harmony. “In the universe all things are closely knit together, they are in one piece, like an ocean: the slightest movement transmits its influence far and wide all around.”[273] From a single grain of sand, Leibnitz holds, the whole universe might be comprehended in its entire development—if we only knew the sand grain thoroughly. There is not really much in all this, though it sounds very fine; for the rest of the universe is considerably more than a grain of sand, well though we knew it, and considerably different therefrom. To say that its essence is the universe is mere empty talk: for the fact is that the universe as essence is not the universe. To the sand grain much must be added which is not present; and since thought adds more than all the grains of sand that exist, the universe and its development may in this way certainly be comprehended. Thus according to Leibnitz every monad has or is the representation of the entire universe, which is the same as saying that it is really representation in general; but at the same time it is a determinate representation, by means of which it comes to be this particular monad, therefore it is representation according to its particular situation and circumstances.[274]
The representations of the monad in itself, which constitute its universe, develop themselves from themselves, as the spiritual element in it, according to the laws of their own activity and desire, just as the movements of their outer world do according to laws of bodies; hence liberty is nothing other than this spontaneity of immanent development, but as in consciousness. The magnetic needle, on the contrary, has only spontaneity without consciousness, and consequently without freedom. For, says Leibnitz, the nature of the magnetic needle is to turn to the north; if it had consciousness it would imagine that this was its self-determination; it would thus have the will to move round in accordance with its nature.[275] But it is clear that in the course of conscious representations there is involved no necessary connection, but contingency and want of sequence are to be found, the reason of this according to Leibnitz (Oper. T. II P. I. p. 75) being “because the nature of a created substance implies that it changes incessantly according to a certain order, which order guides it spontaneously (spontanément) in all the circumstances which befall it; so that one who sees all things recognizes in the present condition of substance the past also and the future. The law of order, which determines the individuality of the particular substance, has an exact reference to what takes place in every other substance and in the whole universe.” The meaning of this is that the monad is not a thing apart, or that there are two views of it, the one making it out as spontaneously generating its representations, so far as form is concerned, and the other making it out to be a moment of the whole of necessity; Spinoza would call this regarding it from both sides. An organic whole, a human being, is thus for instance the assertion of his aim from out of himself: at the same time the being directed on something else is involved in his Notion. He represents this and that to himself, he wills this and that; his activity employs itself and brings about changes. His inward determination thus becomes corporeal determination, and then change going beyond himself; he appears as cause, influencing other monads. But this Being-for-another is only an appearance. For the other, i.e. the actual, in so far as the monad determines it or makes it negative, is the passive element which the monad has in itself: all moments are indeed contained therein, and for that very reason it has no need of other monads, but only of the laws of the monads in itself. But if the Being-for-another is mere appearance, the same may be said of Being-for-self; for this has significance only in reference to Being-for-another.
The important point in Leibnitz’s philosophy is this intellectuality of representation which Leibnitz, however, did not succeed in carrying out; and for the same reason this intellectuality is at the same time infinite multiplicity, which has remained absolutely independent, because this intellectuality has not been able to obtain mastery over the One. The separation in the Notion, which proceeds as far as release from itself, or appearance in distinct independence, Leibnitz did not succeed in bringing together into unity. The harmony of these two moments, the course of mental representations and the course of things external, appearing mutually as cause and effect, is not brought by Leibnitz into relation in and for themselves; he therefore lets them fall asunder, although each is passive as regards the other. He moreover considers both of them in one unity, to be sure, but their activity is at the same time not for themselves. Every forward advance becomes therefore incomprehensible when taken by itself, because the course of the representation as through aims in itself, requires this moment of Other-Being or of passivity; and again the connection of cause and effect requires the universal: each however lacks this its other moment. The unity which according to Leibnitz is to be brought about by the pre-established harmony, namely that the determination of the will of man and the outward change harmonize, is therefore brought about by means of another, if not indeed from without, for this other is God. Before God the monads are not to be independent, but ideal and absorbed in Him.
At this point the demand would come in that in God Himself there should be comprehended the required unity of that which before fell asunder; and God has the special privilege of having laid on Him the burden of what cannot be comprehended. The word of God is thus the makeshift which leads to a unity which itself is only hypothetical; for the process of the many out of this unity is not demonstrated. God plays therefore in the later philosophy a far greater part than in the early, because now the comprehension of the absolute opposition of thought and Being is the chief demand. With Leibnitz the extent to which thoughts advance is the extent of the universe; where comprehension ceases, the universe ceases, and God begins: so that later it was even maintained that to be comprehended was derogatory to God, because He was thus degraded into finitude. In that procedure a beginning is made from the determinate, this and that are stated to be necessary; but since in the next place the unity of these moments is not comprehended, it is transferred to God. God is therefore, as it were, the waste channel into which all contradictions flow: Leibnitz’s Théodicée is just a popular summing up such as this. There are, nevertheless, all manner of evasions to be searched out—in the opposition of God’s justice and mercy, that the one tempers the other; how the fore-knowledge of God and human freedom are compatible—all manner of syntheses which never come to the root of the matter nor show both sides to be moments.
These are the main moments of Leibnitz’s philosophy. It is a metaphysic which starts from a narrow determination of the understanding, namely, from absolute multiplicity, so that connection can only be grasped as continuity. Thereby absolute unity is certainly set aside, but all the same it is presupposed; and the association of individuals with one another is to be explained only in this way, that it is God who determines the harmony in the changes of individuals. This is an artificial system, which is founded on a category of the understanding, that of the absoluteness of abstract individuality. What is of importance in Leibnitz lies in the maxims, in the principle of individuality and the maxim of indistinguishability.
