Diderot and the Encyclopaedists Volume I Part 2

You present to an unbeliever a volume of writings of which you claim to show him the divinity. But, before going into your proofs, he will be sure to put some questions about your collection. Has it always been the same? Why is it less ample now than it was some centuries ago? By what right have they banished this work or that, which another sect reveres, and preserved this or that, which the other has repudiated?... You only answer all these difficulties by the avowal that the first foundations of the faith are purely human; that the choice between the ma.n.u.scripts, the restoration of pa.s.sages, finally the collection, has been made according to rules of criticism. Well, I do not refuse to concede to the divinity of the sacred books a degree of faith proportioned to the certainty of these rules. (-- 59.)

People agree that it is of the last importance to employ none but solid arguments for the defence of a creed. Yet they would gladly persecute those who attempt to cry down the bad arguments. What then, is it not enough to be a Christian? Am I also to be one upon wrong grounds? (--57.)

The less probability a fact has, the more does the testimony of history lose its weight. I should have no difficulty in believing a single honest man who should tell me that the king had just won a complete victory over the allies. But if all Paris were to a.s.sure me that a dead man had come to life again, I should not believe a word of it. That a historian should impose upon us, or that a whole people should be mistaken--there is no miracle in that. (--46.)

What is G.o.d? A question that we put to children, and that philosophers have much trouble to answer. We know the age at which a child ought to learn to read, to sing, to dance, to begin Latin or geometry. It is only in religion that you take no account of his capacity. He scarcely hears what you say, before he is asked, What is G.o.d? It is at the same instant, from the same lips, that he learns that there are ghosts, goblins, were-wolves--and a G.o.d. (--25.)

The diversity of religious opinions has led the deists to invent an argument that is perhaps more singular than sound. Cicero, having to prove that the Romans were the most warlike people in the world, adroitly draws this conclusion from the lips of their rivals. Gauls, to whom if to any, do you yield the palm for courage? To the Romans.

Parthians, after you, who are the bravest of men? The Romans. Africans, whom would you fear, if you were to fear any? The Romans. Let us interrogate the religionists in this fashion, say the deists. Chinese, what religion would be the best, if your own were not the best?

Naturalism. Mussulmans, what faith would you embrace, if you abjured Mahomet? Naturalism. Christians, what is the true religion, if it be not Christianity? Judaism. But you, O Jews, what is the true religion, if Judaism be false? Naturalism. Now those, continues Cicero, to whom the second place is awarded by unanimous consent, and who do not in turn concede the first place to any--it is those who incontestably deserve that place. (--62.)

In all this we notice one constant characteristic of the eighteenth century controversy about revealed religion. The a.s.sailant demands of the defender an answer to all the intellectual or logical objections that could possibly be raised by one who had never been a Christian, and who refused to become a Christian until these objections could be met.

No account is taken of the mental conditions by which a creed is engendered and limited; nor of the train of historic circ.u.mstance which prepares men to receive it. The modern apologist escapes by explaining religion; the apologist of a hundred years ago was required to prove it.

The end of such a method was inevitably a negation. The objective propositions of a creed with supernatural pretensions can never be demonstrated from natural or rationalistic premisses. And if they could be so demonstrated, it would only be on grounds that are equally good for some other creeds with the same pretensions. The sceptic was left triumphantly weighing one revealed system against another in an equal balance.[36]

The position of the writer of the Philosophical Thoughts is distinctly theistic. Yet there is at least one striking pa.s.sage to show how forcibly some of the arguments on the other side impressed him. "I open," says Diderot, "the pages of a celebrated professor, and I read--'Atheists, I concede to you that movement is essential to matter; what conclusion do you draw from that? That the world results from the fortuitous concourse of atoms? You might as well say that Homer's Iliad, or Voltaire's Henriade, is a result of the fortuitous concourse of written characters.' Now for my part, I should be very sorry to use that reasoning to an atheist; the comparison would give him a very easy game to play. According to the laws of the a.n.a.lysis of chances, he would say to me, I ought not to be surprised that a thing comes to pa.s.s when it is possible, and the difficulty of the event is compensated by the number of throws. There is a certain number of throws in which I would safely back myself to bring 100,000 sixes at once with 100,000 dice. Whatever the definite number of the letters with which I am invited fortuitously to produce the Iliad, there is a certain definite number of throws which would make the proposal advantageous for me; nay, my advantage would be infinite if the quant.i.ty of throws accorded to me were infinite. Now, you grant to me that matter exists from all eternity, and that movement is essential to it. In return for this concession, I will suppose with you that the world has no limits; that the mult.i.tude of atoms is infinite, and that this order, which astonishes you, nowhere contradicts itself. Well, from these reciprocal admissions there follows nothing else unless it be this, that the possibility of engendering the universe fortuitously is very small, but that the number of throws is infinite, or in other words, that _the difficulty of the event is more than sufficiently compensated by the mult.i.tude of the throws. Therefore, if anything ought to be repugnant to reason, it is the supposition that,--matter being in motion from all eternity, and there being perhaps in the infinite number of possible combinations an infinite number of admirable arrangements,--none of these admirable arrangements would have been met with, out of the infinite mult.i.tude of all those which_ matter successively took on. Therefore the mind ought to be more astonished at the hypothetical duration of chaos."_[37] (-- 21.)

In a short continuation of the Philosophical Thoughts ent.i.tled On the Sufficiency of Natural Religion, Diderot took the next step, and turned towards that faith which the votaries of each creed allow to be the best after their own. Even here he is still in the atmosphere of negation. He desires no more than to show that revealed religion confers no advantages which are not already secured by natural religion. "The revealed law contains no moral precept which I do not find recommended and practised under the law of nature; therefore it has taught us nothing new upon morality. The revealed law has brought us no new truth; for what is a truth but a proposition referring to an object, conceived in terms which present clear ideas to me, and the connection of which with one another is intelligible to me? Now revealed religion has introduced no such propositions to us. What it has added to the natural law consists of five or six propositions which are not a whit more intelligible to me than if they were expressed in ancient Carthaginian, inasmuch as the ideas represented by the terms, and the connection among these ideas, escape me entirely."[38]

There is no sign in this piece that Diderot had examined the positive grounds of natural religion, or that he was ready with any adequate answer to the argument which Butler had brought forward in the previous decade of the century. We do not see that he is aware as yet of there being as valid objections on his own sceptical principles to the alleged data of naturalistic deism, as to the pretensions of a supernatural religion. He was content with Shaftesbury's position.

Shaftesbury's influence on Diderot was permanent. It did not long remain so full and entire as it was now in the sphere of religious belief, but the traces of it never disappeared from his notions on morals and art.

Shaftesbury's cheerfulness and geniality in philosophising were thoroughly sympathetic to Diderot. The optimistic harmony which the English philosopher, coming after Leibnitz, a.s.sumed as the starting-point of his ethical and religious ideas, was not only highly congenial to Diderot's sanguine temperament; it was a most attractive way of escape from the disorderly and confused theological wilderness of sin, asceticism, miracle, and the other monkeries. This naturalistic religion may seem a very unsafe and comfortless halting-place to us. But to men who heard of religion only in connection with the Bull Unigenitus and confessional certificates, with some act of intolerance or cruelty, with futile disputes about grace and the Five Propositions, the naturalism which Shaftesbury taught in prose and Pope versified was like the dawn after the foulness of night. Those who wished to soften the inhuman rigour of the criminal procedure of the time[39] used to appeal from customary ordinances and written laws to the law natural. The law natural was announced to have preceded any law of human devising. In the same way, those who wished to disperse the darkness of unintelligible dogmas and degraded ecclesiastical usages, appealed to the simplicity, light, and purity of that natural religion which was supposed to have been overlaid and depraved by the special superst.i.tions of the different communities of the world.

"Pope's Essay on Man," wrote Voltaire after his return from England (1728), "seems to me the finest didactic poem, the most useful, the most sublime, that was ever written in any tongue. 'Tis true the whole substance of it is to be found in Shaftesbury's Characteristics, and I do not know why Pope gives all the honour of it to Bolingbroke, without saying a word of the celebrated Shaftesbury, the pupil of Locke."[40]

The ground of this enthusiastic appreciation of the English naturalism was not merely that it made morality independent of religion, which Shaftesbury took great pains to do. It also identified religion with all that is beautiful and harmonious in the universal scheme. It surrounded the new faith with a pure and lofty poetry, that enabled it to confront the old on more than equal terms of dignity and elevation. Shaftesbury, and Diderot after him, enn.o.bled human nature by placing the principle of virtue, the sense of goodness, within the breast of man. Diderot held to this idea throughout, as we shall see. That he did so explains a kind of phraseology about virtue and morality in his letters to Madame Voland and elsewhere, which would otherwise sound disagreeably like cant.

Finally, Shaftesbury's peculiar attribution of beauty to morality, his reference of ethical matters to a kind of taste, the tolerably equal importance attributed by him to a sense of beauty and to the moral sense, all impressed Diderot with a mark that was not effaced. In the text of the Inquiry the author p.r.o.nounces it a childish affectation in the eyes of any man who weighs things maturely to deny that there is in moral beings, just as in corporeal objects, a true and essential beauty, a real sublime. The eagerness with which Diderot seized on this idea from the first, is shown in the declamatory foot-note which he here appends to his original.[41] It was the source, by a process of inverted application, of that ethical colouring in his criticisms on art which made them so new and so interesting, because it carried aesthetic beyond technicalities, and a.s.sociated it with the real impulses and circ.u.mstances of human life.[42]

One of Diderot's writings composed about our present date (1747), the Promenade du Sceptique, did not see the light until after his death. His daughter tells us that a police agent came one day to the house, and proceeded to search the author's room. He found a ma.n.u.script, said, "Good, that is what I am looking for," thrust it into his pocket, and went away. Diderot did his best to recover his piece, but never succeeded.[43] A copy of it came into the hands of Naigeon, and it seems to have been retained by Malesherbes, the director of the press, out of goodwill to the author. If it had been printed, it would certainly have cost him a sojourn in Vincennes.

We have at first some difficulty in realising how he police could know the contents of an obscure author's desk. For one thing we have to remember that Paris, though it had been enormously increased in the days of Law and the System (1719-20), was still of a comparatively manageable size. In 1720, though the population of the whole realm was only fourteen or fifteen millions, that of Paris had reached no less a figure than a million and a half. After the explosion of the System, its artificial expansion naturally came to an end. By the middle of the century the highest estimate of the population does not make it much more than eight hundred thousand.[44] This, unlike the socially unwholesome and monstrous agglomerations of Paris or London in our own time, was a population over which police supervision might be made tolerably effective. It was more like a very large provincial town.

Again, the inhabitants were marked off into groups or worlds with a definiteness that is now no longer possible. One-fifth of the population, for instance, consisted of domestic servants.[45] There were between twenty-eight and thirty thousand professional beggars.[46] The legal circle was large, and was deeply engrossed by its own interests and troubles. The world of authorship, though extremely noisy and profoundly important, still made only a small group. One effect of a censorship is to produce much gossip and whispering about suspected productions before they see the light, and these whispers let the police into as many secrets as they choose to know.

In Diderot's case, his unsuspecting good-nature to all comers made his affairs accessible enough. His house was the resort of all the starving hacks in Paris, and he has left us more than one graphic picture of the literary drudge of that time. He writes, for instance, about a poor devil to whom he had given a ma.n.u.script to copy. "The time for which he had promised it to me expired, and as my man did not appear, I became uneasy, and started in search of him. I found him in a hole about as big as my fist, almost pitch-dark, without the smallest sc.r.a.p of curtain or hanging to cover the nakedness of his walls, a couple of straw-bottomed chairs, a truckle-bed with a quilt riddled by the moths, a box in the corner of the chimney and rags of every sort stuck upon it, a small tin lamp to which a bottle served as support, and on a shelf some dozen first-rate books. I sat talking there for three-quarters of an hour. My man was as bare as a worm, lean, black, dry, but perfectly serene. He said nothing, but munched his crust of bread with good appet.i.te, and bestowed a caress from time to time on his beloved, on the miserable bedstead that took up two-thirds of his room. If I had never learnt before that happiness resides in the soul, my Epictetus of Hyacinth Street would have taught it me right thoroughly."[47]

The history of one of these ragged clients is to our point. "Among those," he wrote to Madame Voland,[48] "whom chance and misery sent to my address was one Glenat, who knew mathematics, wrote a good hand, and was in want of bread. I did all I could to extricate him from his embarra.s.sments. I went begging for customers for him on every side. If he came at meal-times, I would not let him go; if he lacked shoes, I gave him them; now and then I slipped a shilling into his hands as well.

he had the air of the worthiest man in the world, and he even bore his neediness with a certain gaiety that used to amuse me. I was fond of chatting with him; he seemed to set little store by fortune, fame, and most of the other things that charm or dazzle us in life. Seven or eight days ago Damilaville wrote to send this man to him, for one of his friends who had a ma.n.u.script for him to copy. I send him; the ma.n.u.script is entrusted to him--a work on religion and government. I do not know how it came about, but that ma.n.u.script is now in the hands of the lieutenant of police. Damilaville gives me word of this. I hasten to my friend Glenat, to warn him to count no more upon me. 'And why am I not to count upon you?' 'Because you are a marked man. The police have their eyes upon you and 'tis impossible to send work to you.' 'But, my dear sir, there's no risk, so long as you entrust nothing reprehensible to my hands. The police only come here when they scent game. I cannot tell how they do it, but they are never mistaken.' 'Ah well, I at any rate know how it is, and you have let me see much more in the matter than I ever expected to learn from you,' and with that I turn my back on my rascal." Diderot having occasion to visit the lieutenant of police, introduced the matter, and could not withhold an energetic remonstrance against such an odious abuse of a man's kindness of heart, as the introduction of spies to his fireside. M. de Sartine laughed and Diderot took his leave, vowing that all the wretches who should come to him for the future, with cuffs dirty and torn, with holes in their stockings and holes in their shoes, with hair all unkempt, in shabby overcoats with many rents, or scanty black suits with starting seams, with all the tones and looks of distressed worth, would henceforth seem to him no better than police emissaries and scoundrels set to spy on him. The vow, we may be sure, was soon forgotten, but the story shows how seriously in one respect the man of letters in France was worse off than his brother in England.

The world would have suffered no irreparable loss if the police had thrown the Sceptic's Walk into the fire. It is an allegory designed to contrast the life of religion, the life of philosophy, and the life of sensual pleasure. Of all forms of composition, an allegory most depends for its success upon the rapidity of the writer's eye for new felicities. Accuracy, verisimilitude, sustention, count for nothing in comparison with imaginative adroitness and variety. Bunyan had such an eye, and so, with infinitely more vivacity, had Voltaire. Diderot had not the deep sincerity or realism of conviction of the one; nor had he the inimitable power of throwing himself into a fancy, that was possessed by the other. He was the least agile, the least felicitous, the least ready, of composers. His allegory of the avenue of thorns, the avenue of chestnut-trees, and the avenue of flowers, is an allegory, unskilful, obvious, poor, and not any more amusing than if it's matter had been set forth without any attempt at fanciful decoration. The blinded saints among the thorns, and the voluptuous sinners among the flowers, are rather mechanical figures. The translation into the dialect required by the allegorical situation, of a sceptic's aversion for gross superst.i.tion on the one hand, and for gross hedonism on the other, is forced and wooden. The most interesting of the three sections is the second, containing a discussion in which the respective parts are taken by a deist, a pantheist, a subjective idealist, a sceptic, and an atheist. The allegory falls into the background, and we have a plain statement of some of the objections that may be made by the sceptical atheist both to revelation and to natural religion. A starry sky calls forth the usual glorification of the maker of so much beauty. "That is all imagination," rejoins the atheist. "It is mere presumption. We have before us an unknown machine, on which certain observations have been made. Ignorant people who have only examined a single wheel of it, of which they hardly know more than a tooth or two, form conjectures upon the way in which their cogs fit in with a hundred thousand other wheels.

And then to finish like artisans, they label the work with the name of it's author."

The defender justifies this by the argument from a repeater-watch, of which Paley and others have made so much use. We at once ascribe the structure and movement of a repeater-watch to intelligent creation.

"No--things are not equal," says the atheist. "You are comparing a finished work, whose origin and manufacture we know, to an infinite piece of complexity, whose beginnings, whose present condition, and whose end are all alike unknown, and about whose author you have nothing better than guesses."

But does not its structure announce an author? "No; you do not see who nor what he is. Who told you that the order you admire here belies itself nowhere else? Are you allowed to conclude from a point in s.p.a.ce to infinite s.p.a.ce? You pile a vast piece of ground with earth-heaps thrown here or there by chance, but among which the worm and the ant find convenient dwelling-places enough. What would you think of these insects, if, reasoning after your fashion, they fell into raptures over the intelligence of the gardener who had arranged all these materials so delightfully for their convenience?"[49]

In this rudimentary form the chief speaker presses some of the objections to optimistic deism from the point of view of the fixed limitations, the inevitable relativity, of human knowledge. This kind of objection had been more pithily expressed by Pascal long before, in the famous article of his Thoughts, on the difficulty of demonstrating the existence of a deity by light of nature.[50] Diderot's argument does not extend to dogmatic denial. It only shows that the deist is exposed to an attack from the same sceptical armoury from which he had drawn his own weapons for attacking revelation. It is impossible to tell how far Diderot went at this moment. The trenchancy with which his atheist urges his reasoning, proves that the writer was fully alive to its force. On the other hand, the atheist is left in the midst of a catastrophe. On his return home, he finds his children murdered, his house pillaged, and his wife carried off. And we are told that he could not complain on his own principles.

If the absence of witnesses allowed the robber to commit his crime with impunity, why should he not? Again, there is a pa.s.sage in which the writer seems to be speaking his own opinions. An interlocutor maintains the importance of keeping the people in bondage to certain prejudices.

"What prejudices? If a man once admits the existence of a G.o.d, the reality of moral good and evil, the immortality of the soul, future rewards and punishments, what need has he of prejudices? Supposing him initiated in all the mysteries of transubstantiation, consubstantiation, the Trinity, hypostatical union, predestination, incarnation, and the rest, will he be any the better citizen?"[51]

In truth, Diderot's mind was at this time floating in an atmosphere of rationalistic negation, and the moral of his piece, as he hints, points first to the extravagance of Catholicism, next to the vanity of the pleasures of the world, and lastly, to the unfathomable uncertainty of philosophy. Still, we may discern a significant leaning towards the theory of the eternity of matter, which has arranged itself and a.s.sumed variety of form by virtue of its inherent quality of motion.[52]

It is a characteristic and displeasing mark of the time that Diderot in the midst of these serious speculations, should have set himself (1748) to the composition of a story in the kind which the author of the _Sofa_ had made highly popular. The mechanism of this deplorable piece is more grossly disgusting--I mean aesthetically, not morally--than anything to be found elsewhere in the too voluminous library of impure literature.

The idea would seem to have been borrowed from one of the old Fabliaux.[53] But what is tolerable in the quaint and _naf_ verse of the twelfth or thirteenth century, becomes shocking when deliberately rendered by a grave man into bald unblushing prose of the eighteenth.

The humour, the rich sparkle, the wit, the merry _gaillardise_, have all vanished; we are left with the vapid dregs of an obscene anachronism.

Mr. Carlyle, who knows how to be manly in these matters, and affects none of the hypocritical airs of our conventional criticism, yet has not more energetically than truly p.r.o.nounced this "the beastliest of all past, present, or future dull novels." As "the next mortal creature, even a Reviewer, again compelled to glance into that book," I have felt the propriety of our humorist's injunction to such a one, "to bathe himself in running water, put on change of raiment, and be unclean until the even." Diderot himself, as might have been expected, soon had the grace to repent him of this shameful book, and could never hear it mentioned without a very lively embarra.s.sment.[54]

As I have said before,[55] it was such books as this, as Crebillon's novels, as Duclos's Confessions du Comte X., and the dissoluteness of manners indicated by them, which invested Rousseau's New Helosa (1761) with its delightful and irresistible fascinations. Having pointed out elsewhere the significance of the licentiousness from which the philosophic party did not escape untainted,[56] I need not here do more than make two short remarks. First, the corruption which had seized the court after the death of Lewis XIV. in the course of a few years had reached the middle cla.s.s in the town. The loosening of social fibre, caused by the insenate speculation at the time of Law, no doubt furthered the spread of demoralisation. Second, the reaction against the Church involved among its other elements a pa.s.sionate contempt for all asceticism. This happened to fall in with the general relaxation of morals that followed Lewis's gloomy rigour.

Consequently even men of pure life, like Condorcet, carried the theoretical protest against asceticism so far as to vindicate the practical immorality of the time. This is one of those enormous drawbacks that people seldom take into account when they are enumerating the blessings of superst.i.tion. Mediaeval superst.i.tion had produced some advantages, but now came the set-off. Durable morality had been a.s.sociated with a transitory religious faith. The faith fell into intellectual discredit, and s.e.xual morality shared its decline for a short season. This must always be the natural consequence of building sound ethics on the shifting sands and rotting foundations of theology.

Such literature as these tales of Diderot's, was the mirror both of the ordinary practical sentiment and the philosophic theory. A nation pays dearly for one of those outbreaks, when they happen to stamp themselves in a literary form that endures. There are those who hold that Louvet's Faublas is to this day a powerful agent in the depravation of the youth of France. Diderot, however, had not the most characteristic virtues of French writing; he was no master in the art of the _naf_, nor in delicate malice, nor in sprightly cynicism. His book, consequently, has not lived, and we need not waste more words upon it. _Chaque esprit a sa lie_, wrote one who for a while had sat at Diderot's feet;[57] and we may dismiss this tale as the lees of Diderot's strong, careless, sensualised understanding. He was afterwards the author of a work, La Religieuse, on which the superficial critic may easily pour out the vials of affected wrath. There, however, he was executing a profound pathological study in a serious spirit. If the subject is horrible, we have to blame the composition of human character, or the mischievousness of a human inst.i.tution. La Religieuse is no continuation of the vein of defilement which began and ended with the story of 1748--a story which is one among so many ill.u.s.trations of Guizot's saying about the eighteenth century, that it was the most tempting and seductive of all centuries, for it promised full satisfaction at once to all the greatnesses of humanity and to all its weaknesses. Hettner quotes a pa.s.sage from the minor writings of Niebuhr, in which the historian compares Diderot with Petronius, as having both of them been honest and well-intentioned men, who in shameless times were carried towards cynicism by their deep contempt for the prevailing vice. "If Diderot were alive now," says Niebuhr, "and if Petronius had only lived in the fourth instead of the third century, then the painting of obscenity would have been odious to them, and the inducement to it infinitely smaller."[58] There is no trace in Diderot of this deep contempt for the viciousness of his time. All that can be said is that he did not escape it in his earlier years, in spite of the natural wholesomeness and rect.i.tude of his character.

It is worthy of remark that the dissoluteness of the middle portion of the century was not a.s.sociated with the cynical and contemptuous view about women that usually goes with relaxed morality. There was a more or less distinct consciousness of a truth which has ever since grown into clearer prominence with the advance of thought since the Revolution. It is that the sphere and destiny of women are among the three or four foremost questions in social improvement. This is now perceived on all sides, profound as are the differences of opinion upon the proper solution of the problem. A hundred years ago this perception was vague and indefinite, but there was an unmistakable apprehension that the Catholic ideal of womanhood was no more adequate to the facts of life, than Catholic views about science, or property, or labour, or political order and authority.

Diderot has left some curious and striking reflections upon the fate and character of women. He gives no signs of feeling after social reorganisation; he only speaks as one brooding in uneasy meditation over a very mournful perplexity. There is no sentimentalising, after the fashion of Jean Jacques. He does not neglect the plain physical facts, about which it is so difficult in an age of morbid reserve to speak with freedom, yet about which it is fatal to be silent. He indulged in none of those mischievous flatteries of women, which satisfy narrow observers, or c.o.xcombs, or the uxorious. "Never forget," he said, "that for lack of reflection and principles, nothing penetrates down to a certain profoundness of conviction in the understanding of women. The ideas of justice, virtue, vice, goodness, badness, float on the surface of their souls. They have preserved self-love and personal interest with all the energy of nature. Although more civilized than we are outwardly, they have remained true savages inwardly.... It is in the pa.s.sion of love, the access of jealousy, the transports of maternal tenderness, the instants of superst.i.tion, the way in which they show epidemic and popular notions, that women amaze us; fair as the seraphin of Klopstock, terrible as the fiends of Milton.... The distractions of a busy and contentious life break up our pa.s.sions. A woman, on the contrary, broods over her pa.s.sions; they are a fixed point on which her idleness or the frivolity of her duties holds her attention fast.... Impenetrable in dissimulation, cruel in vengeance, tenacious in their designs, without scruples about the means of success, animated by a deep and secret hatred against the despotism of man--it seems as if there were among them a sort of league, such as exists among the priests of all nations.... The symbol of women in general is that of the Apocalypse, on the front of which is inscribed _Mystery_.... If we have more reason than women have, they have far more instinct than we have."[59] All this was said in no bitterness, but in the spirit of the strong observer.

Cynical bitterness is as misplaced as frivolous adulation. Diderot had a deep pity for women. Their physical weaknesses moved him to compa.s.sion.

To these are added the burden of their maternal function, and the burden of unequal laws. "The moment which shall deliver the girl from subjection to her parents is come; her imagination opens to a future thronged by chimaeras; her heart swims in secret delight. Rejoice while thou canst, luckless creature! Time would have weakened the tyranny that thou hast left; time will strengthen the tyranny that awaits thee. They choose a husband for her. She becomes a mother. It is in anguish, at the peril of their lives, at the cost of their charms, often to the damage of their health, that they give birth to their little ones. The organs that mark their s.e.x are subject to two incurable maladies. There is, perhaps, no joy comparable to that of the mother as she looks on her first-born; but the moment is dearly bought. Time advances, beauty pa.s.ses; there come the years of neglect, of spleen, of weariness. 'Tis in pain that Nature disposes them for maternity; in pain and illness, dangerous and prolonged, she brings maternity to its close. What is a woman after that? Neglected by her husband, left by her children, a nullity in society, then piety becomes her one and last resource. In nearly every part of the world, the cruelty of the civil laws against women is added to the cruelty of Nature. They have been treated like weak-minded children. There is no sort of vexation which, among civilised peoples, man cannot inflict upon woman with impunity."[60]

The thought went no further, in Diderot's mind, than this pathetic e.j.a.c.u.l.a.t.i.o.n. He left it to the next generation, to Condorcet and others, to attack the problem practically; effectively to a.s.sert the true theory that we must look to social emanc.i.p.ation in women, and moral discipline in men, to redress the physical disadvantages. Meanwhile Diderot deserves credit for treating the position and character of women in a civilised society with a sense of reality; and for throwing aside those faded gallantries of poetic and literary convention, that screen a broad and dolorous gulf.

CHAPTER IV.

THE NEW PHILOSOPHY.

It is a common prejudice to treat Voltaire as if he had done nothing save write the Pucelle and mock at Habakkuk. Every serious and instructed student knows better. Voltaire's popularisation of the philosophy of Newton (1738) was a stimulus of the greatest importance to new thought in France. In a chapter of this work he had explained with his usual matchless terseness and lucidity Berkeley's theory of vision.

The principle of this theory is, as every one knows, that figures, magnitudes, situations, distances, are not sensations but inferences; they are not the immediate revelations of sight, but the products of a.s.sociation and intellectual construction; they are not directly judged by vision, but by imagination and experience. If this be so, neither situation, nor distance, nor magnitude, nor figure, would be at once discerned by one born blind, supposing him suddenly to receive sight.

Voltaire then describes the results of the operation performed by Cheselden (1728) on a lad who had been blind from his birth. This experiment was believed to confirm all that Locke and Berkeley had foreseen, for it was long before the patient could distinguish objects by size, distance, or shape.[61] Condillac had renewed the interest which Voltaire had first kindled in the subject, by referring to Cheselden's experiment in his first work, which was published in 1746.[62]

It happened that in 1748 Reaumur couched the eyes of a girl who had been born blind. Diderot sought to be admitted to the operation, but the favour was denied him, and he expressed his resentment in terms which, as we shall see, cost him very dear. As he could not witness the experiment, he began to meditate upon the subject, and the result was the _Letter on the Blind for the Use of those who See_. published in 1749--the date, it may be observed in pa.s.sing, of another very important work in the development of materialistic speculation, David Hartley's _Observations on man, his frame, his duty, and his expectations_.

Diderot's real disappointment at not being admitted to the operation was slight. In a vigorous pa.s.sage he shows the difficulties in the way of conducting such an experiment under the conditions necessary to make it conclusive. To prepare the born-blind to answer philosophical interrogatories truly, and then to put these interrogatories rightly, would have been a feat, he declares, not unworthy of the united talents of Newton, Descartes, Locke, and Leibnitz. Unless the patient were placed in such conditions as this, Diderot thinks there would be more profit in questioning a blind person of good sense, than in the answers of an uneducated person receiving sight for the first time under abnormal and bewildering circ.u.mstances.[63] In this he was undoubtedly right. If the experiment could be prepared under the delicate conditions proper to make it demonstrative evidence, it would be final. But the experiment had certainly not been so prepared in his time, and probably never will be.[64]

Read in the light of the rich and elaborate speculative literature which England is producing in our own day, Diderot's once famous Letter on the Blind seems both crude and loose in its thinking. Yet considering the state of philosophy in France at the time of its appearance, we are struck by the acuteness, the good sense, and the originality of many of its positions. It was the first effective introduction into France of these great and fundamental principles; that all knowledge is relative to our intelligence, that thought is not the measure of existence, nor the conceivableness of a proposition the test of its truth, and that our experience is not the limit to the possibilities of things. That is an impatient criticism which dismisses the French philosophers with some light word as radically shallow and impotent. Diderot grasped the doctrine of Relativity in some of the most important and far-reaching of all its bearings. The fact that he and his allies used the doctrine as a weapon of combat against the standing organisation, is exactly what makes their history worth writing about. The standing organisation was the antagonistic doctrine incarnate. It made anthropomorphism and the absolute the very base and spring alike of individual and of social life. No growth was possible until this speculative base had been transformed. Hence the profound significance of what looks like a mere discussion of one of the minor problems of metaphysics. Diderot was not the first to discover Relativity, nor did he establish it; but it was he who introduced it into the literature of his country at the moment when circ.u.mstances were ripe for it.

Condillac, as we have said, had published his first work, the Essay on the Origin of Human Knowledge, three years before (1746). This was a simple and undeveloped rendering of the doctrine of Locke, that the ultimate source of our notions lies in impressions made upon the senses, shaped and combined by reflection. It was not until 1754 that Condillac published his more celebrated treatise on the Sensations, in which he advanced a stride beyond Locke, and instead of tracing our notions to the double source of sensation and reflection, maintained that reflection itself is nothing but sensation "differently transformed." In the first book, again, he had disputed Berkeley's theory of vision: in the second, he gave a reasoned adhesion to it. Now Diderot and Condillac had first been brought together by Rousseau, when all three were needy wanderers about the streets of Paris. They used to dine together once a week at a tavern, and it was Diderot who persuaded a bookseller to give Condillac a hundred crowns for his first ma.n.u.script. "The Paris booksellers," says Rousseau, "are very arrogant and harsh to beginners; and metaphysics, then extremely little in fashion, did not offer a very particularly attractive subject."[65] The constant intercourse between Diderot and Condillac in the interval between the two works of the great apostle of Sensationalism, may well account for the remarkable development in doctrine. This is one of the many examples of the share of Diderot's energetic and stimulating intelligence, in directing and nourishing the movement of the time, its errors and precipitancies included. On the other hand, the share of Condillac in providing a text for Diderot's first considerable performance, is equally evident.

The Letter on the Blind is an inquiry how far a modification of the five senses, such as the congenital absence of one of them, would involve a corresponding modification of the ordinary notions acquired by men who are normally endowed in their capacity for sensation. It considers the Intellect in a case where it is deprived of one of the senses. The writer opens with an account of a visit made by himself and some friends to a man born blind at Puisaux, a place seventy miles from Paris. They asked him in what way he thought of the eyes. "They are an organ on which the air produces the same effect as my stick upon my hand." A mirror he described "as a machine which sets things in relief away from themselves, if they are properly placed in relation to it." This conception had formed itself in his mind in the following way. The blind man only knows objects by touch. He is aware, on the testimony of others, that we know objects by sight as he knows them by touch; he can form no other notion. He is aware, again, that a man cannot see his own face, though he can touch it. Sight, then, he concludes, is a sort of touch, which only extends to objects different from our own visage, and remote from us. Now touch only conveys to him the idea of relief. A mirror, therefore, must be a machine which sets us in relief out of ourselves. How many philosophers, cries Diderot, have employed less subtlety to reach notions just as untrue?

The born-blind had a memory for sound in a surprising degree, and countenances do not present more diversity to us than he observed in voices. The voice has for such persons an infinite number of delicate shades that escape us, because we have not the same reason for attention that the blind have. The help that our senses lend to one another, is an obstacle to their perfection.

The blind man said he should have been tempted to regard persons endowed with sight as superior intelligences, if he had not found out a hundred times how inferior we are in other respects. How do we know--Diderot reflects upon this--that all the animals do not reason in the same way, and look upon themselves as our equals or superiors, notwithstanding our more complex and efficient intelligence? They may accord to us a reason with which we should still have much need of their instinct while they claim to be endowed with an instinct which enables them to do very well without our reason.
