u6So far the argument seems to draw whatever cogency it has from the simplicity and naturalness of the notion of representation. The nature of idea, it is assumed, is to represent plurality in a unified view. If idea did not represent, it would not be idea. And since there is idea (for our minds at least exist and are made up of idea) there is representation. It belongs to idea to represent, and since the whole world has now been interpreted as a system of mutually representing ideations, or ideators, it might seem that all their mutual relations are perfectly natural, a harmony of agreement which could not be other than it is. But if so, why does Leibniz keep saying that the harmony is pre-established, by special and infinitely elaborate divine decrees?

Leibniz himself says that the very nature of representation excludes interaction. By representing environment a mind does not do anything to environment, that is plain. But it is no less plain that environment does nothing to it, either. The act of representing is simply the act of the mind; it represents in view of environment, of course, but not under the causal influence of environment. Representation is a business carried on by the mind on its own account, and in virtue of its innate power to represent.

Very well; but does this consideration really drive us into theology? Is not Leibniz the victim of a familiar fallacy, that of incompletely stated alternatives? 'Either finite beings interact or else they do not directly condition one another. Monads do not interact, therefore they do not directly condition one another. How then explain the actual conformity of their mutual representation, without recourse to divine fore-ordaining?' It seems sufficient to introduce a further alternative in the first line of the argument, and we are rid of the theology. Things may condition the [26] action of a further thing, without acting upon it. It acts of itself, but it acts in view of what they are. We are tempted to conclude that Leibniz has introduced the Deus ex machina with the fatal facility of his age. 'Where a little further meditation on the characters in the play would furnish a natural denouement, he swings divine intervention on to the scene by wires from the ceiling. It is easy for us to reconstruct for him the end of the piece without recourse to stage-machines.'

Is it? No, I fear it is not. There is really no avoiding the pre-established harmony. And so we shall discover, if we pursue our train of reflexion a little further. It is natural, we were saying, than an idea should represent an environment; indeed, it is the representation of one. Given no environment to represent, it would be empty, a mere capacity for representation. Then every idea or ideator, taken merely in itself, is an empty capacity. But of what is the environment of each made up? According to the Leibnitian theory, of further ideas or ideators: of empty capacities, therefore. Then no idea will either be anything in itself, or find anything in its neighbours to represent. An unhappy predicament, like that of a literary clique in which all the members are adepts at discussing one another's ideas--only that unfortunately none of them are provided with any; or like the shaky economics of the fabled Irish village where they all lived by taking in one another's washing.

It is useless, then, to conceive representations as simply coming into existence in response to environment, and modelling themselves on environment. They must all mutually reflect environment or they would not be representations; but they must also exist as themselves and in their own right or there would be no environment for them mutually to represent. Since the world is infinitely various, each representor must have its own distinct character or nature, as our minds have: that is to say, it must represent in its own individual way; and all these endlessly various representations must be so constituted as to form a mutually reflecting harmony. Considered as a representation, each monadical existence simply reflects the universe after its own manner. But considered as something to be represented by the others, it is a self-existent mental life, or world of ideas. Now when we are considering the fact of representation, that which is to be represented comes first and the representation follows upon it. Thus in considering the Leibnitian universe, we must begin with the[27] monads as self-existent mental lives, or worlds of ideas; their representation of one another comes second. Nothing surely, then, but omnipotent creative wisdom could have pre-established between so many distinct given mental worlds that harmony which constitutes their mutual representation.

Our common-sense pluralistic thinking escapes from the need of the pre-established harmony by distinguishing what we are from what we do. Let the world be made up of a plurality of agents in a 'loose' order, with room to manoeuvre and to adjust themselves to one another. Then, by good luck or good management, through friction and disaster, by trial and error, by accident or invention, they may work out for themselves a harmony of action. There is no need for divine preordaining here. But on Leibniz's view what the monads do is to represent, and what they are is representation; there is no ultimate distinction between what they are and what they do: all that they do belongs to what they are. The whole system of action in each monad, which fits with such infinite complexity the system of action in each other monad, is precisely the existence of that monad, and apart from it the monad is not. The monads do not achieve a harmony, they are a harmony, and therefore they are pre-established in harmony.

Leibniz denied that he invoked God to intervene in nature, or that there was anything arbitrary or artificial about his physical theology. He was simply analysing nature and finding it to be a system of mutual representation; he was analysing mutual representation and finding it to be of its nature intrinsically pre-established, and therefore God-dependent. He was not adding anything to mutual representation, he was just showing what it necessarily contained or implied. At least he was doing nothing worse than recognized scholastic practice. Scholastic Aristotelianism explained all natural causality as response to stimulus, and then had to postulate a stimulus which stimulated without being stimulated, and this was God. Apart from this supreme and first stimulus nothing would in fact be moving. The Aristotelians claimed simply to be analysing the nature of physical motion as they perceived it, and to find the necessity of perpetually applied divine stimulation implicit in it. No violence was thereby done to the system of physical motion nor was anything brought in from without to patch it up; it was simply found to be of its own [28] nature God-dependent.

It seems as though the reproachful description 'Deus ex machina' should be reserved for more arbitrary expedients than Aristotle's or Leibniz's, say for the occasionalist theory. Occasionalism appeared to introduce God that he might make physical matter do what it had no natural tendency to do, viz. to obey the volitions of finite mind. Ideas, on the other hand, have a natural tendency to represent one another, for to be an idea is to be a representation; God is not introduced by Leibniz to make them correspond, he is introduced to work a system in which they shall correspond. This may not be Deus-ex-machina philosophy, but it is physical theology; that is to say, it treats divine action as one factor among the factors which together constitute the working of the natural system. And this appears to be perhaps unscientific, certainly blasphemous: God's action cannot be a factor among factors; the Creator works through and in all creaturely action equally; we can never say 'This is the creature, and that is God' of distinguishable causalities in the natural world. The creature is, in its creaturely action, self-sufficient: but because a creature, insufficient to itself throughout, and sustained by its Creator both in existence and in action.

The only acceptable argument for theism is that which corresponds to the religious consciousness, and builds upon the insufficiency of finite existence throughout, because it is finite. All arguments to God's existence from a particular gap in our account of the world of finites are to be rejected. They do not indicate God, they indicate the failure of our power to analyse the world-order. When Leibniz discovered that his system of mutual representations needed to be pre-established, he ought to have seen that he had come up a cul-de-sac and backed out; he ought not to have said, 'With the help of God I will leap over the wall.'

If we condemn Leibniz for writing physical theology, we condemn not him but his age. No contemporary practice was any better, and much of it a good deal worse, as Leibniz liked somewhat complacently to point out. And because he comes to theology through physical theology, that does not mean that all his theology was physical theology and as such to be written off. On the contrary, Leibniz is led to wrestle with many problems which beset any philosophical theism of the Christian type. This is particularly so[29] in the Theodicy, as its many citations of theologians suggest. His discussions never lack ingenuity, and the system of creation and providence in which they result has much of that luminous serenity which colours the best works of the Age of Reason.
