Theodicy Part 1

Theodicy.

by G. W. Leibniz.

INTRODUCTION

I

Leibniz was above all things a metaphysician. That does not mean that his head was in the clouds, or that the particular sciences lacked interest for him. Not at all--he felt a lively concern for theological debate, he was a mathematician of the first rank, he made original contributions to physics, he gave a realistic attention to moral psychology. But he was incapable of looking at the objects of any special enquiry without seeing them as aspects or parts of one intelligible universe. He strove constantly after system, and the instrument on which his effort relied was the speculative reason. He embodied in an extreme form the spirit of his age. Nothing could be less like the spirit of ours. To many people now alive metaphysics means a body of wild and meaningless a.s.sertions resting on spurious argument. A professor of metaphysics may nowadays be held to deal handsomely with the duties of his chair if he is prepared to handle metaphysical statements at all, though it be only for the purpose of getting rid of them, by showing them up as confused forms of something else. A chair in metaphysical philosophy becomes a.n.a.logous to a chair in tropical diseases: what is taught from it is not the propagation but the cure.

Confidence in metaphysical construction has ebbed and flowed through philosophical history; periods of speculation have been followed by periods of criticism. The tide will flow again, but it has not turned yet, and [8]

such metaphysicians as survive scarcely venture further than to argue a case for the possibility of their art. It would be an embarra.s.sing task to open an approach to Leibnitian metaphysics from the present metaphysical position, if there is a present position. If we want an agreed starting-point, it will have to be historical.

The historical importance of Leibniz's ideas is anyhow unmistakable. If metaphysical thinking is nonsensical, its empire over the human imagination must still be confessed; if it is as chimerical a science as alchemy, it is no less fertile in by-products of importance. And if we are to consider Leibniz historically, we cannot do better than take up his _Theodicy_, for two reasons. It was the only one of his main philosophical works to be published in his lifetime, so that it was a princ.i.p.al means of his direct influence; the Leibniz his own age knew was the Leibniz of the _Theodicy_.

Then in the second place, the _Theodicy_ itself is peculiarly rich in historical material. It reflects the world of men and books which Leibniz knew; it expresses the theological setting of metaphysical speculation which still predominated in the first years of the eighteenth century.

Leibniz is remembered for his philosophy; he was not a professional philosopher. He was offered academic chairs, but he declined them. He was a gentleman, a person of means, librarian to a reigning prince, and frequently employed in state affairs of trust and importance. The librarian might at any moment become the political secretary, and offer his own contributions to policy. Leibniz was for the greater part of his active life the learned and confidential servant of the House of Brunswick; when the Duke had nothing better to do with him, he set him to research into ducal history. If Leibniz had a profession in literature, it was history rather than philosophy. He was even more closely bound to the interests of his prince than John Locke was to those of the Prince of Orange. The Houses of Orange and of Brunswick were on the same side in the princ.i.p.al contest which divided Europe, the battle between Louis XIV and his enemies. It was a turning-point of the struggle when the Prince of Orange supplanted Louis's Stuart friends on the English throne. It was a continuation of the same movement, when Leibniz's master, George I, succeeded to the same throne, and frustrated the restoration of the Stuart heir. Locke returned to England in the wake of the Prince of Orange, and became the [9]

representative thinker of the regime. Leibniz wished to come to the English court of George I, but was unkindly ordered to attend to the duties of his librarianship. So he remained in Hanover. He was then an old man, and before the tide of favour had turned, he died.

Posterity has reckoned Locke and Leibniz the heads of rival sects, but politically they were on the same side. As against Louis's political absolutism and enforced religious uniformity, both championed religious toleration and the freedom of the mind. Their theological liberalism was political prudence; it was not necessarily for that reason the less personally sincere. They had too much wisdom to meet bigotry with bigotry, or set Protestant intolerance against Catholic absolutism. But they had too much sympathy with the spirit of Europe to react into free thinking or to make a frontal attack on revealed truth. They took their stand on a fundamental Christian theism, the common religion of all good men; they repudiated the negative enormities of Hobbes and Spinoza.

The Christian was to hold a position covered by three lines of defences.

The base line was to be the substance of Christian theism and of Christian morals, and it was to be held by the forces of sheer reason, without aid from scriptural revelation. The middle line was laid down by the general sense of Scripture, and the defence of it was this. 'Scriptural doctrine is reconcilable with the findings of sheer reason, but it goes beyond them. We believe the Scriptures, because they are authenticated by marks of supernatural intervention in the circ.u.mstances of their origin. We believe them, but reason controls our interpretation of them.' There remained the most forward and the most hazardous line: the special positions which a Church, a sect, or an individual might found upon the scriptural revelation. A prudent man would not hold his advance positions in the same force or defend them with the same obstinacy as either of the lines behind them. He could argue for them, but he could not require a.s.sent to them.

One cannot help feeling, indeed, the readiness of these writers to fall back, not only from the front line to the middle line, but from the middle line itself to the base line. Leibniz, for example, writes with perfect seriousness and decency about the Christian scheme of redemption, but it hardly looks like being for him a crucial deliverance from perdition. It is not the intervention of Mercy, by which alone He possesses himself of [10]

us: it is one of the ways in which supreme Benevolence carries out a cosmic policy; and G.o.d's benevolence is known by pure reason, and apart from Christian revelation.

In one politically important particular the theological att.i.tude of Leibniz differed from that of Locke. Both stood for toleration and for the minimizing of the differences between the sects. This was a serious enough matter in England, but it was an even more serious matter in Germany. For Germany was divided between Catholics and Protestants; effective toleration must embrace them both. English toleration might indulge a harmless Catholic minority, while rejecting the Catholic regime as the embodiment of intolerance. But this was not practical politics on the Continent; you must tolerate Catholicism on an equal footing, and come to terms with Catholic regimes. Leibniz was not going to d.a.m.n the Pope with true Protestant fervour. It was his consistent aim to show that his theological principles were as serviceable to Catholic thinkers as to the doctors of his own church. On some points, indeed, he found his most solid support from Catholics; in other places there are hints of a joint Catholic-Lutheran front against Calvinism. But on the whole Leibniz's writings suggest that the important decisions cut across all the Churches, and not between them.

Leibniz was impelled to a compromise with 'popery', not only by the religious divisions of Germany, but (at one stage) by the political weakness of the German Protestant States. At the point of Louis XIV's highest success, the Protestant princes had no hope but in Catholic Austria, and Austria was distracted by Turkish pressure in the rear.

Leibniz hoped to relieve the situation by preaching a crusade. Could not the Christian princes sink their differences and unite against the infidel?

And could not the Christian alliance be cemented by theological agreement?

Hence Leibniz's famous negotiation with Bossuet for a basis of Catholic-Lutheran concord. It was plainly destined to fail; and it was bound to recoil upon its author. How could he be a true Protestant who treated the differences with the Catholics as non-essentials? How could he have touched pitch and taken no defilement? Leibniz was generally admired, but he was not widely trusted. As a mere politician, he may be judged to have over-reached himself.

It has been the object of the preceding paragraphs to show that Leibniz[11]

the politician and Leibniz the theologian were one and the same person; not at all to suggest that his rational theology was just political expediency.

We may apply to him a parody of his own doctrine, the pre-established harmony between nature and grace. Everything happens as though Leibniz were a liberal politician, and his theology expressed his politics. Yes, but equally, everything happens as though Leibniz were a philosophical theologian, and his politics expressed his theology. His appreciation of Catholic speculation was natural and sincere; his dogmatic ancestry is to be looked for in Thomism and Catholic humanism as much as anywhere. Above all, he had himself a liberal and generous mind. It gave him pleasure to appreciate good wherever he could see it, and to discover a soul of truth in every opinion.

From the moment when Leibniz became aware of himself as an independent thinker, he was the man of a doctrine. Sometimes he called it 'my principles', sometimes 'the new system', sometimes 'pre-established harmony'. It could be quite briefly expressed; he was always ready to oblige his friends with a summary statement, either in a letter or an enclosed memorandum, and several such have come down to us. The doctrine may have been in Leibniz's view simple, but it was applicable to every department of human speculation or enquiry. It provided a new alphabet of philosophical ideas, and everything in heaven and earth could be expressed in it; not only could be, but ought to be, and Leibniz showed tireless energy in working out restatements of standing problems.

As a man with an idea, with a philosophical nostrum, Leibniz may be compared to Bishop Berkeley. There was never any more doubt that Leibniz was a Leibnitian than that Berkeley was a Berkeleian. But there is no comparison between the two men in the width of their range. About many things Berkeley never took the trouble to Berkeleianize. To take the most surprising instance of his neglect--he a.s.sured the world that his whole doctrine pointed to, and hung upon, theology. But what sort of a theology?

He scarcely took the first steps in the formulation of it. He preferred to keep on defending and explaining his _esse est percipi_. With Leibniz it is wholly different; he carries his new torch into every corner, to illuminate the dark questions.

The wide applicability of pre-established harmony might come home to its inventor as a rich surprise. The reflective historian will find it less[12]

surprising, for he will suspect that the applications were in view from the start. What was Leibniz thinking of when the new principle flashed upon him? What was he _not_ thinking of? He had a many-sided mind. If the origins of the principle were complex, little wonder that its applications were manifold. Every expositor of Leibniz who does not wish to be endlessly tedious must concentrate attention on one aspect of Leibniz's principle, and one source of its origin. We will here give an account of the matter which, we trust, will go most directly to the heart of it, but we will make no claims to sufficient interpretation of Leibniz's thought-processes.

Leibniz, then, like all the philosophers of the seventeenth century, was reforming scholasticism in the light of a new physical science. The science was mathematical in its form, mechanistical in its doctrine, and unanswerable in its evidence--it got results. But it was metaphysically intractable, and the doctrines of infinite and finite substance which it generated furnish a gallery of metaphysical grotesques; unless we are to except Leibniz; his system is, if nothing else, a miracle of ingenuity, and there are moments when we are in danger of believing it.

It is a natural mistake for the student of seventeenth-century thought to underestimate the tenacity of scholastic Aristotelianism. Descartes, we all know, was reared in it, but then Descartes overthrew it; and he had done his work and died by the time that Leibniz was of an age to philosophize at all. We expect to see Leibniz starting on his shoulders and climbing on from there. We are disappointed. Leibniz himself tells us that he was raised in the scholastic teaching. His acquaintance with Descartes's opinions was second-hand, and they were retailed to him only that they might be derided. He agreed, like an amiable youth, with his preceptors.

The next phase of his development gave him a direct knowledge of Cartesian writings, and of other modern books beside, such as those of the atomist Ga.s.sendi. He was delighted with what he read, because of its fertility in the field of physics and mathematics; and for a short time he was an enthusiastic modern. But presently he became dissatisfied. The new systems did not go far enough, they were still scientifically inadequate. At the same time they went too far, and carried metaphysical paradox beyond the limits of human credulity.

[13]

There is no mystery about Leibniz's scientific objections to the new philosophers. If he condemned them here, it was on the basis of scientific thought and observation. Descartes's formulation of the laws of motion could, for example, be refuted by physical experiment; and if his general view of physical nature was bound up with it, then so much the worse for the Cartesian philosophy. But whence came Leibniz's more strictly metaphysical objections? Where had he learned that standard of metaphysical adequacy which showed up the inadequacy of the new metaphysicians? His own disciples might be satisfied to reply, that he learnt it from Reason herself; but the answer will not pa.s.s with us. Leibniz reasoned, indeed, but he did not reason from nowhere, nor would he have got anywhere if he had. His conception of metaphysical reason was what his early scholastic training had made it.

There are certain absurd opinions which we are sure we have been taught, although, when put to it, we find it hard to name the teacher. Among them is something of this sort. 'Leibniz was a scholarly and sympathetic thinker. He had more sense of history than his contemporaries, and he was instinctively eclectic. He believed he could learn something from each of his great predecessors. We see him reaching back to cull a notion from Plato or from Aristotle; he even found something of use in the scholastics.

In particular, he picked out the Aristotelian "entelechy" to stop a gap in the philosophy of his own age.' What this form of statement ignores is that Leibniz _was_ a scholastic: a scholastic endeavouring, like Descartes before him, to revolutionize scholasticism. The word 'entelechy' was, indeed, a piece of antiquity which Leibniz revived, but the thing for which it stood was the most familiar of current scholastic conceptions.

'Entelechy' means active principle of wholeness or completion in an individual thing. Scholasticism was content to talk about it under the name of 'substantial form' or 'formal cause'. But the scholastic interpretation of the idea was hopelessly discredited by the new science, and the scholastic terms shared the discredit of scholastic doctrine. Leibniz wanted a term with a more general sound. 'There is an _X_', he wanted to say, 'which scholasticism has defined as substantial form, but I am going to give a new definition of it.' Entelechy was a useful name for _X_, the more so as it had the authority of Aristotle, the master of scholasticism.

Under the name of entelechy Leibniz was upholding the soul of [14]

scholastic doctrine, while retrenching the limbs and outward flourishes.

The doctrine of substantial form which he learnt in his youth had had _something_ in it; he could not settle down in the principles of Descartes or of Ga.s.sendi, because both ignored this vital _something_. Since the requirements of a new science would not allow a return to sheer scholasticism, it was necessary to find a fresh philosophy, in which entelechy and mechanism might be accommodated side by side.

If one had asked any 'modern' of the seventeenth century to name the 'ancient' doctrine he most abominated, he would most likely have replied, 'Substantial form'. Let us recall what was rejected under this name, and why.

The medieval account of physical nature had been dominated by what we may call common-sense biology. Biology, indeed, is the science of the living, and the medievals were no more inclined than we are to endow all physical bodies with life. What they did do was to take living bodies as typical, and to treat other bodies as imperfectly a.n.a.logous to them. Such an approach was _a priori_ reasonable enough. For we may be expected to know best the physical being closest to our own; and we, at any rate, are alive.

Why not argue from the better known to the less known, from the nearer to the more remote, interpreting other things by the formula of our own being, and allowing whatever discount is necessary for their degree of unlikeness to us?

Common-sense biology reasons as follows. In a living body there is a certain pattern of organized parts, a certain rhythm of successive motions, and a certain range of characteristic activities. The pattern, the sheer anatomy, is basic; but it cannot long continue to exist (outside a refrigerator) without accompanying vital rhythms in heart, respiration and digestion. Nor do these perform their parts without the intermittent support of variable but still characteristic activities: dogs not only breathe and digest, they run about, hunt their food, look for mates, bark at cats, and so on. The anatomical pattern, the vital rhythm, and the characteristic acts together express d.o.g.g.i.ness; they reveal the specific form of the dog. They _reveal_ it; exactly what the specific form _consisted in_ was the subject of much medieval speculation. It need not concern us here.

Taking the form of the species for granted, common-sense biology proceeds to ask how it comes to be in a given instance, say in the dog Toby. [15]

Before this dog was born or thought of, his form or species was displayed in each of his parents. And now it looks as though the form of dog had detached itself from them through the generative act, and set up anew on its own account. How does it do that? By getting hold of some materials in which to express itself. At first it takes them from the body of the mother, afterwards it collects them from a wider environment, and what the dog eats becomes the dog.

What, then, is the relation of the a.s.similated materials to the dog-form which a.s.similates them? Before a.s.similation, they have their own form.

Before the dog eats the leg of mutton, it has the form given to it by its place in the body of a sheep. What happens to the mutton? Is it without remainder transubstantiated from sheep into dog? It loses all its distinctively sheep-like characteristicsm but there may be some more basically material characteristics which it preserves. They underlay the structure of the mutton, and they continue to underlie the structure of the dog's flesh which supplants it. Whatever these characteristics may be, let us call them common material characteristics, and let us say that they belong to or compose a common material nature.

The common material nature has its own way of existing, and perhaps its own principles of physical action. We may suppose that we know much or that we know little about it. This one thing at least we know, that it is capable of becoming alternatively either mutton or dog's flesh. It is not essential to it to be mutton, or mutton it would always be; nor dog's flesh, or it would always be dog's flesh. It is capable of becoming either, according as it is captured by one or other system of formal organization. So the voters who are to go to the polls are, by their common nature, Englishmen; they are essentially neither Socialist curs nor Conservative sheep, but intrinsically capable of becoming either, if they become captured by either system of party organization.

According to this way of thinking, there is a certain _looseness_ about the relation of the common material nature to the higher forms of organization capable of capturing it. Considered in itself alone, it is perhaps to be seen as governed by absolutely determined laws of its own. It is heavy, then it will fall unless obstructed; it is solid, then it will resist intrusions. But considered as material for organization by higher forms, it is indeterminate. It acts in one sort of way under the persuasion of the sheep-form, and in another sort of way under the persuasion of the [16]

dog-form, and we cannot tell how it will act until we know which form is going to capture it. No amount of study bestowed on the common material nature will enable us to judge how it will behave under the persuasion of the higher organizing form. The only way to discover that is to examine the higher form itself.

Every form, then, will really be the object of a distinct science. The form of the sheep and the form of the dog have much in common, but that merely happens to be so; we cannot depend upon it, or risk inferences from sheep to dog: we must examine each in itself; we shall really need a science of probatology about sheep, and cynology about dogs. Again, the common material nature has its own principles of being and action, so it will need a science of itself, which we may call hylology. Each of these sciences is mistress in her own province; but how many there are, and how puzzlingly they overlap! So long as we remain within the province of a single science, we may be able to think rigorously, everything will be 'tight'. But as soon as we consider border-issues between one province and another, farewell to exact.i.tude: everything will be 'loose'. We can think out hylology till we are blue in the face, but we shall never discover anything about the entry of material elements into higher organizations, or how they behave when they get there. We may form perfect definitions and descriptions of the form of the dog as such, and still derive no rules for telling what elements of matter will enter into the body of a given dog or how they will be placed when they do. All we can be sure of is, that the dog-form will keep itself going in, and by means of, the material it embodies--unless the dog dies. But what happens to the matter in the body of the dog is 'accidental' to the nature of the matter; and the use of this matter, rather than of some other equally suitable, is accidental to the nature of the dog.

No account of material events can dispense with accidental relations altogether. We must at least recognize that there are accidental relations between particular things. Accident in the sense of brute fact had to be acknowledged even by the tidiest and most dogmatic atomism of the last century. That atomism must allow it to be accidental, in this sense, that the s.p.a.ce surrounding any given atom was occupied by other atoms in a given manner. It belonged neither to the nature of s.p.a.ce to be occupied by just those atoms in just those places, nor to the nature of the atoms to be [17]

distributed just like that over s.p.a.ce; and so in a certain sense the environment of any atom was an accidental environment. That is, the particular arrangement of the environment was accidental. The nature of the environment was not accidental at all. It was proper to the nature of the atom to be in interaction with other atoms over a spatial field, and it never encountered in the fellow-denizens of s.p.a.ce any other nature but its own. It was not subject to the accident of meeting strange natures, nor of becoming suddenly subject to strange or unequal laws of interaction. All interactions, being with its own kind, were reciprocal and obedient to a single set of calculable laws.

But the medieval philosophy had a.s.serted accidental relations between distinct sorts of _natures_, the form of living dog and the form of dead matter, for example. No one could know _a priori_ what effect an accidental relation would produce, and all accidental relations between different pairs of natures were different: at the most there was a.n.a.logy between them. Every different nature had to be separately observed, and when you had observed them all, you could still simply write an inventory of them, you could not hope to rationalize your body of knowledge. Let us narrow the field and consider what this doctrine allows us to know about the wood of a certain kind of tree. We shall begin by observing the impressions it makes on our several senses, and we shall attribute to it a substantial form such as naturally to give rise to these impressions, without, perhaps, being so rash as to claim a knowledge of what this substantial form is. Still we do not know what its capacities of physical action and pa.s.sion may be. We shall find them out by observing it in relation to different 'natures'. It turns out to be combustible by fire, resistant to water, tractable to the carpenter's tools, intractable to his digestive organs, harmless to ostriches, nourishing to wood-beetles. Each of these capacities of the wood is distinct; we cannot relate them intelligibly to one another, nor deduce them from the a.s.sumed fundamental 'woodiness'.

We can now see why 'substantial forms' were the _betes noires_ of the seventeenth-century philosophers. It was because they turned nature into an unmanageable jungle, in which trees, bushes, and parasites of a thousand kinds wildly interlaced. There was nothing for it, if science was to proceed, but to clear the ground and replant with spruce in rows: to postulate a single uniform nature, of which there should be a single science. Now neither probatology nor cynology could hope to be [18]

universal--the world is not all sheep nor all dog: it would have to be hylology; for the world is, in its spatial aspect, all material. Let us say, then, that there is one uniform material nature of things, and that everything else consists in the arrangements of the basic material nature; as the show of towers and mountains in the sunset results simply from an arrangement of vapours. And let us suppose that the interactions of the parts of matter are all like those which we can observe in dead manipulable bodies--in mechanism, in fact. Such was the postulate of the new philosophers, and it yielded them results.

It yielded them results, and that was highly gratifying. But what, meanwhile, had happened to those palpable facts of common experience from which the whole philosophy of substantial forms had taken its rise? Is the wholeness of a living thing the mere resultant of the orderly operations of its parts? Is a bee no more essentially one than a swarm is? Is the life of a living animal indistinguishable from the rhythm of a going watch, except in degree of complication and subtlety of contrivance? And if an animal's body, say my own, is simply an agglomerate of minute interacting material units, and its wholeness is merely accidental and apparent, how is my conscious mind to be adjusted to it? For my consciousness appears to identify itself with that whole vital pattern which used to be called the substantial form. We are now told that the pattern is nothing real or active, but the mere accidental resultant of distinct interacting forces: it does no work, it exercises no influence or control, it _is_ nothing. How then can it be the vehicle and instrument of my conscious soul? It cannot.

Then is my soul homeless? Or is it to be identified with the activity and fortunes of a single atomic const.i.tuent of my body, a single cog in the animal clockwork? If so, how irrational! For the soul does not experience itself as the soul of one minute part, but as the soul of the body.

Such questions rose thick and fast in the minds of the seventeenth-century philosophers. It will cause us no great surprise that Leibniz should have quickly felt that the Formal Principle of Aristotle and of the Scholastic philosophy must be by hook or by crook reintroduced--not as the detested _substantial form_, but under a name by which it might hope to smell more sweet, _entelechy_.

Nothing so tellingly revealed the difficulties of the new philosophy in[19]

dealing with living bodies as the insufficiency of the solutions Descartes had proposed. He had boldly declared the unity of animal life to be purely mechanical, and denied that brutes had souls at all, or any sensation. He had to admit soul in man, but he still denied the substantial unity of the human body. It was put together like a watch, it was many things, not one: if Descartes had lived in our time, he would have been delighted to compare it with a telephone system, the nerves taking the place of the wires, and being so arranged that all currents of 'animal spirit' flowing in them converged upon a single unit, a gland at the base of the brain. In this unit, or in the convergence of all the motions upon it, the 'unity' of the body virtually consisted; and the soul was incarnate, not in the plurality of members (for how could it, being one, indwell many things?), but in the single gland.
