Diderot and the Encyclopaedists Volume I Part 7

We are constantly being puzzled and diverted by Diderot's ingenuity in wandering away from the topic nominally in hand, to insinuate some of those doctrines of tolerance, of suspended judgment, or of liberty, which lay so much nearer to his heart than any point of mere erudition.

There is a little article on Aius-Locutius, the Announcing Speaker, one of the minor Roman G.o.ds. Diderot begins by a few lines describing the rise of the deity into repute. He then quotes Cicero's pleasantry on the friendly divinity, that when n.o.body in the world had ever heard of him, he delivered a salutary oracle, but after people had built him a fine temple, then the G.o.d of speech fell dumb. This suggests to Diderot to wonder with edifying innocence how so religious a people as the Romans endured these irreverent jests in their philosophers. By an easy step we pa.s.s to the conditions on which modern philosophers should be allowed by authority to publish their speculations. Diderot throws out the curious hint that it would be best to forbid any writing against government and religion in the vulgar tongue, and to allow those who write in a learned tongue to publish what they please. And so we bid farewell to Aius-Locutius. In pa.s.sing, we ask ourselves whether Diderot's suggestion is not available in the discussion of certain questions, where freedom of speech in the vernacular tongue is scarcely compatible with the _reverentia quae debetur pueris_?

Diderot is never prevented by any mistaken sense of the dignity of his enterprise from interspersing his disquisitions on science and philosophy with such practical thoughts on the common matters of daily life as come into his ingenious head. He suggests, for instance, by way of preventing the frauds of cab-drivers on their masters and on the public, that all payments of fares should be made to appointed officers at the various cab-stations, and that no driver should take up a fare except at one of these stations.[175] In writing about lackeys, after a word on their insolence and on the wretched case in which most of them end their days, he points out that the mult.i.tude of them is causing the depopulation of the fields. They are countrymen who have thronged to Paris to avoid military service. Peasants turned lackeys to escape the conscription, just as in our own days they turn priests. Then, says Diderot, this evil ought to be checked by a tax upon liveries; but such a tax is far too sensible ever to be imposed.

Yet, notwithstanding the practical and fervid temper of his understanding, Diderot is not above literary trifling when the humour seizes him. If he can write an exhaustive article on Encyclopaedia, or Spinosa, or Academies, or Weaving, he can also stoop to Anagrams, and can tell us that the letters of Frere Jacques Clement, the a.s.sa.s.sin of Henry III., make up the sinister words, _C'est l'enfer qui m'a cree_. He can write a couple of amusing pages on Onomatomancy, or divination of a man's fortune from his name; and can record with neutral gravity how frequently great empires have been destroyed under princes bearing the same name as their first founders; how, again, certain names are unlucky for princes, as Cains among the Romans, John in France, England, and Scotland, and Henry in France.

We have now and then an anecdote that is worth reading and worth preserving. Thus, under Machiavellist: "I have heard that a philosopher, being asked by a great prince about a refutation of Machiavellism, which the latter had just published, replied, 'Sire, I fancy that the first lesson that Machiavelli would have given to his disciple would have been to refute his work.'" Whether Voltaire ever did say this to the great Frederick, is very questionable, but it would not have been ill said.

After the reader has been taken through a short course of Arabian philosophy, he is enlivened by a selection of poetic sayings about human life from the Rose-garden of Sadi, and the whole article winds up with an eastern fable, of no particular relevancy, of three men finding a treasure, and of one of them poisoning the food for which the other two had sent him; on his return they suddenly fell on him and slew him, and then ate the poisoned food, and so the treasure fell to none of them.[176]

We have spoken in the previous section of the contempt expressed by D'Alembert for mere literary antiquarianism--a very different thing, let us remember, from scientific inquiry into the origin and cla.s.sification of inst.i.tutions and social organs. Diderot's article on the Germans is an excellent ill.u.s.tration of this wholesome predominance of the scientific spirit over the superficialities of barren erudition. The word "Allemand," says Diderot, "has a great many etymologies, but they are so forced, that it is almost as well to know none of them, as to know them all. As for the origin of this famous stock, all that has been said on that matter, between Tacitus and Clovis, is simply a tissue of guesses without foundation." Of course in this some persons will see a shameful levity; others will regard it as showing very good sense, and a right estimate of what is knowable and worth knowing, and what is neither one nor the other. In the article on Celibacy we notice the same temper. A few sentences are enough for the antiquarianism of the subject, what the Egyptians, Greeks, and Romans thought and ordained about celibacy. The substance of the article is a reproduction of the Abbe Saint Pierre's discussion of the advantages that would be gained for France, with her declining population, if her forty thousand cures were allowed to marry, and to bring into the world eighty thousand children. We may believe that Diderot smiled as he transcribed the Abbe's cunning suggestion that a dispensing power to relieve from the obligation of celibacy should be recognised in the Pope, and that the Roman court should receive a sum of money for every dispensation so granted.

Although, however, Diderot despised mere bookishness, his article on Libraries is one of the longest and most painstaking, furnishing a tolerably complete list of the most famous collections, from the beginning of books down to the latest additions to the King's Library in the Rue Vivienne. In the course of this article he quotes with seeming approval the quaint words in which old Richard of Bury, the author of the _Philobiblon_ (1340), praised books as the best of masters, much as the immortal defender of the poet Archias had praised them: "Hi sunt magistri qui nos instruunt sine virgis et ferulis, sine cholera, sine pecunia; si accedis non dormiunt; si inquiris non se abscondunt; non obmurmurant si oberres; cachinnos nesciunt si ignores."

In literature proper, as in philosophy, Diderot loses no opportunity of insisting on the need of being content with suspended judgment. For instance, he blames historians of opinion for the readiness with which they attribute notions found in one or two rabbis to the whole of the Jews, or because two or three Fathers say something, boldly set this down as the sentiments of a whole century, although perhaps we have nothing else save these two or three Fathers left of the century, and although we do not know whether their writings were applauded, or were even widely known. "It were to be wished that people should speak less affirmatively, especially on particular points and remote consequences, and that they should only attribute them directly to those in whose writings they are actually to be found. I confess that the history of the sentiments of antiquity would not seem so complete, and that it would be necessary to speak in terms of doubt much more often than is common; but by acting otherwise we expose ourselves to the danger of taking false and uncertain conjectures for ascertained and unquestionable truths. The ordinary man of letters does not readily put up with suspensive expressions, any more than common people do so." All this is an odd digression to be found under the head of Hylopathianism, but it must always remain wholesome doctrine.

We cannot wonder at Diderot's admiration for Montaigne and for Bayle, who, with Hume, would make the great trinity of scepticism. "The work of Montaigne," said Diderot, "is the touchstone of a good intelligence; you may be sure that any one whom the reading of Montaigne displeases has some vice either of heart or understanding. As for Bayle, he has had few equals in the art of reasoning, and perhaps no superior; and though he piles doubt upon doubt, he always proceeds with order; an article of his is a living polypus, which divides itself into a number of polypuses, all living, engendered one from the other."[177] Yet Diderot had a feeling of the necessity of advancing beyond the att.i.tude of Bayle and Montaigne. Intellectual suspense and doubt was made difficult to him by his vehement and positive demand for emotional certainties.

Diderot is always ready to fling away his proper subject in a burst of moralising. The article on _Man_, as a branch of natural history, contains a correct if a rather superficial account of that curious animal; at length the writer comes to a table showing the probable duration of life at certain ages. "You will observe," he says, "1st, that the age of seven is that at which you may hope a longer life; 2d, that at twelve or thirteen you have lived a quarter of your life; at twenty-eight or twenty-nine you have lived half; at fifty more than three-quarters." And then he suddenly winds up the whole performance by the exclamation: "O ye who have laboured up to fifty, who are in the enjoyment of comfort, and who still have left to you health and strength, what then are you waiting for before you take rest? How long will you go on saying _To-morrow, to-morrow?_"

There are many casual brilliancies in the way of a.n.a.logy and parallel, many aptnesses of thought and phrase. The Stoics are called the Jansenists of Paganism. "For a single blade of gra.s.s to grow, it is necessary that the whole of nature should co-operate." "A man comes to Pyrrhonism by one of two opposite ways; either because he does not know enough, or because he knows too much; the latter is not the most common way." And so forth.

If we turn to the group of articles dealing with theology, it is difficult for us to know exactly where we are. Sometimes Diderot writes of popular superst.i.tions with the gravity proper to a dictionary of mythology. Sometimes he sews on to the sober gray of his scepticism a purple patch of theistic declamation.[178] The article on Jesus Christ is obviously a mere piece of common form, and more than one pa.s.sage in his article on _Christianisme_ is undoubtedly insincere. When we come to his more careful article, _Providence_, we find it impossible to extract from it a body of coherent propositions of which we could confidently say that they represented his own creed, or the creed that he desired his readers to bear away in their minds.

It is hardly worth while to measure the more or the less of his adherence to Christianity, or even to Deism, as inferred from the Encyclopaedia. We need only turn to his private letters to find that he is in no degree nor kind an adherent, but the most hardy, contemptuous, and thoroughgoing of opponents. At the risk of shocking devout persons, I am bound to reproduce a pa.s.sage from one of his letters, in which there can be no doubt that we have Diderot's true mind, as distinguished from what it was convenient to print. "The Christian religion," he says, "is to my mind the most absurd and atrocious in its dogmas; the most unintelligible, the most metaphysical, the most intertwisted and obscure, and consequently the most subject to divisions, sects, schisms, heresies; the most mischievous for the public tranquillity, the most dangerous to sovereigns by its hierarchic order, its persecutions, its discipline; the most flat, the most dreary, the most Gothic, and the most gloomy in its ceremonies; the most puerile and unsociable in its morality, considered not in what is common to it with universal morality, but in what is peculiarly its own, and const.i.tutes it evangelical, apostolical, and Christian morality, which is the most intolerant of all. Lutheranism, freed from some absurdities, is preferable to Catholicism; Protestantism to Lutheranism, Socinianism to Protestantism, Deism, with temples and ceremonies, to Socinianism. Since it is necessary that man, being superst.i.tious by nature, should have a fetish, the simplest and most harmless will be the best fetish."[179] We need not discuss nor extend the quotation; enough has been said to relieve us from the duty of a.n.a.lysing or criticising articles in which Christianity is treated with all the formal respect that the secular authority insisted upon.

This formal respect is not incompatible with many veiled and secret sarcasms, which were as well understood as they were sharply enjoyed by those who read between the lines. It is not surprising that these sarcasms were constantly unjust and shallow. Even those of us who repudiate theology and all its works for ourselves, may feel a shock at the coa.r.s.eness and impurity of innuendo which now and then disfigures Diderot's treatment of theological as of some other subjects. For this the att.i.tude of the Church itself was much to blame; coa.r.s.e, virulent, unspiritual as it was in France in those days. Voltaire, Diderot, Holbach, would have written in a very different spirit, even while maintaining and publishing the same attacks on theological opinion, if the Church of France had possessed such a school of teachers as the Church of England found in the Lat.i.tudinarians in the seventeenth century; or such as she finds now in the nineteenth century in those who have imported, partly from the poetry of Wordsworth, partly from the historic references of the Oxford Tracts, an equity, a breadth, an elevation, a pensive grace, that effectually forbid the use of those more brutal weapons of controversy which were the only weapons possible in France a century ago.

We have already said so much of the great and important group of articles on arts and trades, that it is unnecessary to add anything further as to Diderot's particular share in them. He visited all the workshops in Paris; he sent for information and specifications to the most important seats of manufacture in the kingdom; he sometimes summoned workmen from the provinces to describe to him the paper works of Montargis, and the silk works and velvet works of Lyons.[180] Much of Diderot's work, even on great practical subjects, was, no doubt, the reproduction of mere book-knowledge acquired at second-hand. Take, for instance, Agriculture, which was undoubtedly the most important of all subjects for France at that date, as indeed at every other date. There are a dozen pages of practical precepts, for which Diderot was probably indebted to one of the farmers at Grandval. After this, he fills up the article with about twenty pages in which he gives an account of the new system of husbandry, which our English Jethro Tull described to an unbelieving public between 1731 and 1751. Tull's volume was translated into French by Duhamel, with notes and the record of experiments of his own; from this volume Diderot drew the pith of his article. Diderot's only merit in the matter--and it is hardly an inconsiderable one in a world of routine--is that he should have been at the pains to seek the newest lights, and above all that he should have urged the value of fresh experiments in agriculture. Tull was not the safest authority in the world, but it is to be remembered that the shrewd-witted Cobbett thought his ideas on husbandry worth reproducing, seventy years after Diderot had thought them worth compiling into an article.

It was not merely in the details of the practical arts that Diderot wrote from material acquired at second-hand. The article on the Zend-Avesta is taken from the Annual Register for 1762. The long series of articles on the history of philosophy is in effect a reproduction of what he found in Bayle, in Deslandes, and in Brucker. There are one or two considerable exceptions. Perhaps the most important is under the heading of Spinosa, to which we shall return presently. The article on _Hobbisme_ contains an a.n.a.lysis, evidently made by the writer's own hand, of the bulk of Hobbes's propositions; it is scarcely, however, illuminated by a word of criticism. If we turn to the article on _Societe_, it is true, we find Hobbes's view of the relations between the civil and temporal powers tolerably effectively combated, but even here Diderot hardly does more than arm himself with the weapons of Locke.

Of course, he honestly refers his readers to these sources of wider information.[181] All that we can say of the articles on the history of philosophy is that the series is very complete; that Diderot used his matter with intelligence and the spirit of criticism, and that he often throws in luminous remarks and far-reaching suggestions of his own. This was all that the purpose of his book required. To imitate the laborious literary search of Bayle or of Brucker, and to attempt to compile an independent history of philosophy, would have been to sacrifice the Encyclopaedia as a whole, to the superfluous perfection of a minor part.

There is only one imperative condition in such a case, namely, that the writer should pa.s.s the accepted material through his own mind before reproducing it. With this condition it was impossible for a man of Diderot's indefatigable energy of spirit, not as a rule to comply.

But this rule too had exceptions. There were cases in which he reproduced, as any mere bookmaker might have done, the thought of his authority, without an attempt to make it his own. Of the confusion and inequalities in which Diderot was landed by this method of mingling the thoughts of other people with his own, there is a curious example in the two articles on Philosopher and Philosophy. In the first we have an essentially social and practical description of what the philosopher should be; in the second we have a definition of philosophy, which takes us into the regions most remote from what is social and practical. We soar to the airiest heights of verbal a.n.a.lysis and pure formalism.

Nothing can be better, so far as it goes, than the picture of the philosopher. Diderot begins by contrasting him with the crowd of people, and clever people, who insist on pa.s.sing judgment all day long. "They ignore the scope and limits of the human mind; they think it capable of knowing everything; hence they think it a disgrace not to p.r.o.nounce judgment, and imagine that intelligence consists in that and nothing else. The philosopher believes that it consists in judging rightly. He is better pleased with himself when he has suspended his faculty of coming to a conclusion, than if he had come to a conclusion without the proper grounds. He prefers to brilliancy the pains of rightly distinguishing his ideas, of finding their true extent and exact connection. He is never so attached to a system as not to feel all the force of the objections to it. Most men are so strongly given over to their opinions that they do not take any trouble to make out those of others. The philosopher, on the other hand, understands what he rejects, with the same breadth and the same accuracy as he understands what he adopts." Then Diderot turns characteristically from the intellectual to the social side. "Our philosopher does not count himself an exile in the world; he does not suppose himself in an enemy's country; he would fain find pleasure with others, and to find it he must give it; he is a worthy man who wishes to please and to make himself useful. The ordinary philosophers who meditate too much, or rather who meditate to wrong purpose, are as surly and arrogant to all the world as great people are to those whom they do not think their equals; they flee men, and men avoid them. But our philosopher who knows how to divide himself between retreat and the commerce of men is full of humanity. _Civil society is, so to say, a divinity for him on the earth_; he honours it by his probity, by an exact attention to his duties, and by a sincere desire not to be a useless or an embarra.s.sing member of it. The sage has the leaven of order and rule; he is full of the ideas connected with the good of civil society. What experience shows us every day is that the more reason and light people have, the better fitted they are and the more to be relied on for the common intercourse of life."[182]

The transition is startling from this conception of

Philosopher as a very high kind of man of the world, to the definition of Philosophy as "the science of possibles qua possibles." Diderot's own reflection comes back to us, _Combien cette maudite metaphysique fait des fous!_[183] We are abruptly plunged from a Baconian into a Leibnitzian atmosphere. We should naturally have expected some such account of Philosophy as that it begins with a limitation of the questions to which men can hope for an answer, and ends in an ordered arrangement of the principles of knowledge, with ultimate reference to the conditions of morals and the structure of civil societies. We should naturally have expected to find, what indeed we do find, that the characteristic of the philosopher is to "admit nothing without proof, never to acquiesce in illusory notions; to draw rigorously the dividing lines of the certain, the probable, the doubtful; above all things never to pay himself with mere words." But then these wholesome prescriptions come in an article whose definitions and distribution of philosophy are simply a reproduction from Christian Wolff, and the methods and dialect of Wolff are as essentially alien from the positive spirit of the Encyclopaedia as they were from the mystic spirit of Jacobi.

Wolff's place in the philosophical succession of German speculation (1679-1754) is between Leibnitz and Kant, and until Kant came his system was dominant in the country of metaphysics.[184] It is from Wolff that Diderot borrows and throws una.s.similated into the pages of the Encyclopaedia propositions so fundamentally incongruous as this, that "among all possibles there must of necessity be a Being subsisting by himself; otherwise there would be possible things, of the possibility of which no account could be given, an a.s.sertion that could never be made." It is a curious thing, and it ill.u.s.trates again the strangely miscellaneous quality of Diderot's compilation, that the very article which begins by this incorporation of the author of a philosophical system expounded in a score of quartos, ends by a vigorous denunciation of the introduction of the systematic spirit into philosophy.

I shall venture to quote a hardy pa.s.sage from another article (_Pyrrhonienne_) which some will think a measure of Diderot's philosophical incompetency, and others will think a measure of his good sense. "We will conclude," he says, "for our part that as all in nature is bound together, there is nothing, properly speaking, of which man has perfect, absolute, and complete knowledge, because for that he would need knowledge of all. Now as all is bound together, it inevitably happens that, from discussion to discussion, he must come to something unknown: then in starting again from this unknown point, we shall be justified in pleading against him the ignorance or the obscurity or the uncertainty of the point preceding, and of that preceding this, and so forth, up to the most evident principle. So we must admit a sort of sobriety in the use of reason. When step by step I have brought a man to some evident proposition, I shall cease to dispute. I will listen no longer to a man who goes on to deny the existence of bodies, the rules of logic, the testimony of the senses, the difference between good and evil, true and false, etc. etc. I will turn my back on everybody who tries to lead me away from a simple question, to embark me in discussion as to the nature of matter, of the understanding of thought, and other subjects sh.o.r.eless and bottomless."[185] Whatever else may be said of this, we have to recognise that it is exactly characteristic of the author. But then why have written on metaphysics at all?

We have mentioned the article on Spinosa. It is characteristic both of the good and the bad sides of Diderot's work. Half of it is merely a reproduction of Bayle's criticisms on Spinosa and his system. The other half consists of original objections propounded by Diderot with marked vigour of thrust against Spinosa, but there is no evidence that he had gone deeper into Spinosa than the first book of the Ethics. There is no certain sign that he had read anything else, or that he had more of that before him than the extracts that were furnished by Bayle. Such treatment of a serious subject hardly conforms to the modern requirements of the literary conscience, for in truth the literary conscience has now turned specialist and shrinks from the encyclopaedic.

Diderot's objections are, as we have said, pushed with marked energy of speech. "However short away," he says, "you penetrate into the thick darkness in which Spinosa has wrapped himself up, you discover a succession of abysses into which this audacious reasoner has precipitated himself, of propositions either evidently false or evidently doubtful, of arbitrary principles, subst.i.tuted for natural principles and sensible truths; an abuse of terms taken for the most part in a wrong sense, a ma.s.s of deceptive equivocations, a cloud of palpable contradictions." The system is monstrous, it is absurd and ridiculous. It is Spinosa's plausible method that has deceived people; they supposed that one who employed geometry, and proceeded by way of axioms and definitions, must be on the track of truth. They did not see that these axioms were nothing better than very vague and very uncertain propositions; that the definitions were inexact, defective, and bizarre.

We have no s.p.a.ce to follow the reasoning by which Diderot supports this scornful estimate of the famous thinker, of whom it can never be settled whether he be pantheist, atheist, akosmist, or G.o.d-intoxicated man. He returns to the charge again and again, as if he felt a certain secret uneasiness lest for scorn so loudly expressed he had not brought forward adequate justification. And the reader feels that Diderot has scarcely hit the true line of cleavage that would have enabled him--from his own point of view--to shatter the Spinosist system. He tries various bouts of logic with Spinosa in connection with detached propositions. Thus he deals with Spinosa's third proposition, that, _in the case of things that have nothing in common with one another, one cannot be the cause of the other_. This proposition, Diderot contends, is false in all moral and occasional causes. The sound of the name of G.o.d has nothing in common with the idea of the Creator which that name produces in my mind.

A misfortune that overtakes my friend has nothing in common with the grief that I feel in consequence. When I move my arm by an act of will, the movement has nothing in common in its nature with the act of my will; they are very different. I am not a triangle, yet I form the idea of one and I examine its properties. So with the fifth proposition, that _there cannot be in the universe two or more substances of the same nature or the same attributes_. If Spinosa is only talking of the essence of things or of their definition, what he says is naught; for it can only mean that there cannot be in the universe two different essences having the same essence. Who doubts it? But if Spinosa means that there cannot be an essence which is found in various single objects, in the same way as the essence of triangle is found in the triangle A and the triangle B, then he says what is manifestly untrue.

It is not, however, until the last two or three pages that Diderot sets forth his dissent in its widest form.

"To refute Spinosa," he says at last, "all that is necessary is to stop him at the first step, without taking the trouble to follow him into a ma.s.s of consequences; all that we need do is to subst.i.tute for the obscure principle which he makes the base of his system, the following: namely, that _there are several substances_--a principle that in its own way is clear to the last degree. And, in fact, what proposition can be clearer, more striking, more close to the understanding and consciousness of man? I here seek no other judge than the most just impression of the common sense that is spread among the human race....

Now, since common sense revolts against each of Spinosa's propositions, no less than against the first, of which they are the pretended proofs, instead of stopping to reason on each of these proofs where common sense is lost, we should be right to say to him:--Your principle is contrary to common sense; from a principle in which common sense is lost, nothing can issue in which common sense is to be found again."

The pa.s.sage sounds unpleasantly like an appeal to the crowd in a matter of science, which is as the sin against the Holy Ghost in these high concerns. What Diderot meant, probably, was to charge Spinosa with inventing a conception of substance which has no relation to objective experience; and further with giving fantastic answers to questions that were in themselves never worth asking, because the answers must always involve a violent wrench of the terms of experience into the sphere transcending experience, and because, moreover, they can never be verified. Whether he meant this or something else, and whether he would have been right or wrong in such an intention, we may admit that it would have been more satisfactory if in dealing with such a master-type of the metaphysical method as Spinosa, so acute a positive critic as Diderot had taken more pains to give to his objections the utmost breadth of which they were capable.[186]

The article on Leibnitz has less original matter in it than that on Spinosa. The various speculations of that great and energetic intellect in metaphysic, logic, natural theology, natural law, are merely drawn out in a long table of succinct propositions, while the account of the life and character of Leibnitz is simply taken from the excellent _eloge_ which had been published upon him by Fontenelle in 1716.

Fontenelle's narrative is reproduced in a generous spirit of admiration and respect for a genius that was like Diderot's own in encyclopaedic variety of interest, while it was so far superior to Diderot's in concentration, in subtlety, in precision, in power of construction. If there could exist over our heads, says Diderot, a species of beings who could observe our works as we watch those of creatures at our feet, with what surprise would such beings have seen those four marvellous insects, Bayle, Descartes, Leibnitz, and Newton. And he then draws up a little calendar of the famous men, out of whom we must choose the name to be placed at the very head of the human race. The list contains, besides Julian the Apostate--who was inserted, we may presume, merely by way of playful insult to the ecclesiastical enemy--Socrates, Marcus Aurelius, Trajan, Bacon, and the four great names that have just been cited.

Germany derives as much honour from Leibnitz alone, he concludes with unconsidered enthusiasm, as Greece from Plato, Aristotle, and Archimedes, all put together. As we have said, however, there is no criticism, nor any other sign that Diderot had done more than survey the facade of the great Leibnitzian structure admiringly from without.

The article on Liberty would be extremely remarkable, appearing where it does, and coming from a thinker of Diderot's general capacity, if only we could be sure that Diderot was sincere. As it happens, there is good reason to suppose that he was wholly insincere. It is quite as shallow, from the point of view of philosophy, as his article on the Jews or on the Bible is from the point of view of erudition. One reason for this might not be far to seek. We have repeatedly observed how paramount the social aim and the social test are in Diderot's mind over all other considerations. But this reference of all subjects of discussion to the good of society, and this measurement of conclusions by their presumed effect on society, is a method that has its own dangers. The aversion of ecclesiastics to unfettered discussion, lest it should damage inst.i.tutions and beliefs deemed useful to mankind, is the great leading example of this peril. Diderot, it might be said by those who should contend that he wrote what he thought, did not escape exactly the same predicament, as soon as ever he forgot that of all the things that are good for society, Truth is the best. Now, who will believe that it is Diderot, the persecuted editor of the Encyclopaedia, and the author of the manly article on Intolerance, who introduces such a pa.s.sage as the following into the discussion of the everlasting controversy of Free Will and Necessity: "Take away Liberty, and you leave no more vice nor virtue nor merit in the world; rewards are ridiculous, and punishments unjust. The ruin of Liberty overthrows all order and all police, confounds vice and virtue, authorises every monstrous infamy, extinguishes the last spark of shame and remorse, degrades and disfigures beyond recovery the whole human race. _A doctrine of such enormity as this ought not to be examined in the schools; it ought to be punished by the magistrates._"[187] Of course, this was exactly what the Jesuits said about a belief in G.o.d, about revelation, and about the inst.i.tutions of the church. To take away these, they said, is to throw down the bulwarks of order, and an attempt to take them away, as by encyclopaedists or others, ought to be punished by the magistrates.

Diderot had for the moment clearly lost himself.

We need hardly be surprised if an article conceived in this spirit contains no serious contribution to the difficult question with which it deals. Diderot had persuaded himself that, without Free Will, all those emotional moralities in the way of sympathy and benevolence and justice which he adored would be lowered to the level of mere mechanism.

"If men are not free in what they do of good and evil, then," he cries, in what is surely a paroxysm of unreason, "good is no longer good, and evil no longer evil." As if the outward quality and effects of good and evil were not independent of the mental operations which precede human action. Murder would not cease to be an evil simply because it had been proved that the murderer's will to do a bad deed was the result of antecedents. Acts have marks and consequences of their own, good or bad, whatever may be the state of mind of those who do them. But Diderot does not seem to divine the true issue; he writes as if Necessarians or Determinists denied the existence of volitions, and as if the question were whether volitions do exist. n.o.body denies that they exist; the real question is of the conditions under which they exist. Are they determined by antecedents, or are they self-determined, spontaneous, and unconnected? Is Will independent of cause?

Diderot's argumentation is, in fact, merely a protest that man is conscious of a Will. And just as in other parts of his article Diderot by Liberty means only the existence of Will, so by Liberty he means only the healthy condition of the soul, and not its independence of causation. We need not waste words on so dire a confusion, nor on the theory that Will is sometimes dependent on cerebral antecedents and sometimes not. The curious thing is that the writer should not have perceived that he was himself in this preposterous theory propounding the very principle which he denounced as destructive to virtue, ruinous to society, and worthy of punishment by the government. For it seems that, after all, the Will of those whose "dispositions are not moderate"

is not free; and we may surely say that those whose dispositions are least moderate, are exactly the most violent malefactors against the common weal. One more pa.s.sage is worth quoting to show how little the writer had seized the true meaning of the debate. "According to you," he says to Bayle, "it is not clear that it is at the pure choice of my will to move my arm or not to move it: if that be so, it is then necessarily determined that within a quarter of an hour from now I shall lift my hand three times together, or that I shall not. Now, if you seriously pretend that I am not free, you cannot refuse an offer that I make you; I will wager a thousand pistoles to one that I will do, in the matter of moving my hand, exactly the opposite to what you back; and you may take your choice. If you do think the wager fair, it can only be because of your necessary and invincible judgment that I am free." As if the will to move or not to move the arm would be uncaused and unaffected by antecedents, when you have just provided so strong an antecedent as the desire to save a thousand pistoles. It was, perhaps, well enough for Voltaire to content himself with vague poetical material for his poetical discourse on Liberty, but from Diderot, whether as editor or as writer, something better might have been expected than a clumsy reproduction of the reasoning by which men like Turretini had turned philosophy into the corrupted handmaid of theology.

The most extraordinary thing about this extraordinary article still remains to be told. It was written, we may suppose, between 1757 and 1762, or about that time. In June, 1756, Diderot wrote to a certain Landois, a fellow-worker on the Encyclopaedia, a letter containing the most emphatic possible repudiation of the whole doctrine of Liberty.

"Liberty is a word void of sense; there are not and there never can have been free beings; we are only what fits in with the general order, with organisation, with education, and with the chain of events. We can no more conceive a being acting without a motive than we can conceive one of the arms of a balance acting without a weight; and the motive is always exterior and foreign to us, attached either by nature or by some cause or other that is not ourselves. _There is only one sort of causes, properly speaking, and those are, physical causes._"[188] And so forth in the vein of hard and remorseless necessarianism, which we shall find presently in the pages of the System of Nature.[189]

There is only one explanation of this flagrant contradiction. Diderot must have written on Liberty just as he wrote on Jesus Christ or the Bible. He cannot have said what he thought, but only what the persons in authority required him to pretend to think. We may he sure that a letter to an intimate would be more likely to contain his real opinion than an article published in the Encyclopaedia. That such mystifications are odious, are shameful, are almost too degrading a price to pay for the gains of such a work, we may all readily enough admit. All that we can do is to note so flagrant a case, as a striking example of the common artifices of the time. One other point we may note. The fervour and dexterity with which Diderot made what he knew to be the worse appear the better cause, make a still more striking example of his astonishing dramatic power of throwing himself, as dialectician, casuist, sophist, into a false and illusive part.

Turning from the philosophical to the political or social group of articles, we find little to add to what has been said in the previous section. One of the most excellent essays in this group is that on Luxury. Diderot opens ingeniously with a list of the propositions that state the supposed evils of luxury, and under each proposition he places the most striking case that he can find in history of its falseness. He goes through the same process with the propositions a.s.serting the gains of luxury to society. Having thus effectually disposed of any wholesale way of dealing with the subject, he proceeds to make a number of observations on the gains and drawbacks of luxury; these are full of sense and freedom from commonplace. Such articles as _Pouvoir, Souverain, Autorite_, do little more than tell over again the old unhistoric story about a society surrendering a portion of its sovereign power to some individual or dynasty to hold in trust. It is worth remarking how little democratic were Diderot and his school in any Jacobinical, or anarchic, or even more respectable modern sense. There is in Diderot's contributions many a firm and manly plea for the self-respect of the common people, but not more than once or twice is there a syllable of the disorder which smoulders under the pages of Rousseau. Thus: "When the dwellers among the fields are well treated, the number of proprietors insensibly grows greater, the extreme distance and the vile dependence of poor on rich grow less; hence the people have courage, force of soul, and strength of body; they love their country, they respect the magistrates, they are attached to a prince, to an order, and to laws to which they owe their peace and well-being. And you will no longer see the son of the honourable tiller of the soil so ready to quit the n.o.ble calling of his forefathers, nor so ready to go and sully himself with the liveries and with the contempt of the man of wealth."[190]

No one can find fault with democratic sentiment of this kind, nor with the generous commonplaces of the moralist, about virtue being the only claim to honour, and vice the only true source of shame and inferiority.

But neither Diderot nor Voltaire ever allowed himself to flatter the crowd for qualities which the crowd can scarcely possess. The little article on Mult.i.tude seems merely inserted for the sake of buffeting unwarranted pretensions. "Distrust the judgment of the mult.i.tude in all matters of reasoning and philosophy; there its voice is the voice of malice, folly, inhumanity, irrationality, and prejudice. Distrust it again in things that suppose much knowledge or a fine taste. The mult.i.tude is ignorant and dulled. Distrust it in morality; it is not capable of strong and generous actions; it rather wonders at such actions than approves them; heroism is almost madness in its eyes.

Distrust it in the things of sentiment; is delicacy of sentiment so common a thing that you can accord it to the mult.i.tude? In what then is the mult.i.tude right? In everything, but only at the end of a very long time, because then it has become an echo, repeating the judgment of a small number of sensible men who shape the judgment of posterity for it beforehand. If you have on your side the testimony of your conscience, and against you that of the mult.i.tude, take comfort and be a.s.sured that time does justice." It is far from being a universal gift among men of letters and others to unite this fastidious estimation of the incapacity of the crowd in the higher provinces of the intellectual judgment, with a fervid desire that the life of the crowd should be made worthy of self-respecting men.

The same hand that wrote the defiance of the populace that has just been quoted, wrote also this short article on Misery: "There are few souls so firm that misery does not in the long run cast them down and degrade them. The poor common people are incredibly stupid. I know not what false dazzling prestige closes their eyes to their present wretchedness, and to the still deeper wretchedness that awaits the years of old age.

Misery is the mother of great crimes. It is the sovereigns who make the miserable, and it is they who shall answer in this world and the other for the crimes that misery has committed."

So far as the mechanism of government is concerned, Diderot writes much as Montesquieu had done. Under the head of _Representants_ he proclaims the advantages, not exactly of government by a representative a.s.sembly, but of a.s.sisting and advising the royal government by means of such an a.s.sembly. There is no thought of universal suffrage. "_It is property that makes the citizen_; every man who has possessions in the state is interested in the state, and whatever be the rank that particular conventions may a.s.sign to him, it is always as a proprietor; it is by reason of his possessions that he ought to speak, and that he acquires the right of having himself represented." Yet this very definite statement does not save him from the standing difficulty of a democratic philosophy of politics. Nor can it be reconciled in point of logic with other propositions to which Diderot commits himself in the same article.

For instance, he says that "no order of citizens is capable of stipulating for all; if one order had the right, it would very soon come to stipulate only for itself; each cla.s.s ought to be represented by men who know its condition and its needs; _these needs are only well known to those who actually feel them_." But then, in that case, the poorest cla.s.ses are those who have most need of direct representation; they are the most numerous, their needs are sharpest, they are the cla.s.ses to which war, consumption of national capital and way of expending national income, equal laws, judicial administration, and the other concerns of a legislative a.s.sembly, come most close. The problem is to reconcile the sore interests of the mult.i.tude with the ignorance and the temper imputed in Diderot's own description of them.

An interesting study might be made, if the limits of our subject permitted such a digression, on the new political ideas which a century's experience in England, France, Germany, the American Union, has added to the publicist's stock. Diderot's article on the Legislator is a curious mixture of views which political thinkers have left behind, with views which the most enlightened statesmen have taken up. There is much talk after the fashion of Jean Jacques Rousseau about the admirable legislation of Lycurgus at Sparta, the philosophical government of the great empire of China, and the fine spirit of the inst.i.tutions of Peru.

We perceive that the same influences which made Rousseau's political sentimentalism so popular also brought even strong heads like Diderot to believe in the unbounded power of a government to mould men at its will, and to impose inst.i.tutions at discretion. The idea that it is the main function of a government to make its people virtuous, is generally as strong in Diderot as it was in Rousseau, and as it became in Robespierre. He admires the emperors of China, because their edicts are as the exhortation of a father to his children. All edicts, he says, ought to instruct and to exhort as much as they command. Yet two years after the Encyclopaedia was finished (1774), when Turgot prefaced his reforming edicts by elaborate and reasoned statements of the grounds for them, it was found that his prefaces caused greater provocation than the very laws that they introduced.

Apart from the common form of enthusiasm for the "sublime legislation"

of countries which the writer really knew nothing about, the article on the Legislator has some points worth noticing. We have seen how Diderot made the possession of property the true note of citizenship, and of a claim to share in the government. But he did not pay property this compliment for nothing. It is, he says, the business of the legislator to do his best to make up to mankind for the loss of that equality which was one of the comforts that men surrendered when they gave up the state of nature. Hence the legislator ought to take care that no one shall reach a position of extreme opulence otherwise than by an industry that enriches the state. "He must take care that the charges of society shall fall upon the rich, who enjoy the advantages of society." Even those who agree with Diderot, and are ready to vote for a graduated income-tax, will admit that he comes to his conclusion without knowing or reflecting about either the serious arguments for it, or the serious objections against it.

What is really interesting in this long article is its antic.i.p.ation of those ideas which in England we a.s.sociate with the name of Cobden. "All the men of all lands have become necessary to one another for the exchange of the fruits of industry and the products of the soil.

Commerce is a new bond among men. Every nation has an interest in these days in the preservation by every other nation of its wealth, its industry, its banks, its luxury, its agriculture. The ruin of Leipsic, of Lisbon, and of Lima has led to bankruptcies on all the exchanges of Europe, and has affected the fortunes of many millions of persons."[191]

In the same spirit he foresees the decline of patriotism in its older and narrower sense, and the predominance of the international over the national sentiment. "All nations now have sufficiently just ideas of their neighbours, and consequently they have less enthusiasm for their country than in the old days of ignorance. There is little enthusiasm where there is much light; enthusiasm is nearly always the emotion of a soul that is more pa.s.sionate than it is instructed. By comparing among all nations laws with laws, talents with talents, and manners with manners, nations will find so little reason to prefer themselves to others, that if they preserve for their own country that love which is the fruit of personal interest, at least they will lose that enthusiasm which is the fruit of an exclusive self-esteem."

Yet Diderot had the perspicacity to discern the drawbacks to such a revolution in the conditions of social climate. "Commerce, like enlightenment, lessens ferocity, but also, just as enlightenment takes away the enthusiasm of self-esteem, so perhaps commerce takes away the enthusiasm of virtue. It gradually extinguishes the spirit of magnanimous disinterestedness, and replaces it by that of hard justice.

By turning men's minds rather to use than beauty, to prudence rather than to greatness, it may be that it injures the strength, the generosity, the n.o.bleness of manners."
