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 passage 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 God, 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 assumed 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 æsthetically, 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 naïf 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 pronounced 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 embarrassment.[54]
As I have said before,[55] it was such books as this, as Crébillon's novels, as Duclos's Confessions du Comte
X., and the dissoluteness of manners indicated by them, which invested Rousseau's New Heloïsa (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 class 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 passionate 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 superstition. Mediæval superstition had produced some advantages, but now came the set-off. Durable morality had been associated with a transitory religious faith. The faith fell into intellectual discredit, and sexual 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 naïf, 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 institution. 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 illustrations 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 passage 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 rectitude of his character.
It is worthy of remark that the dissoluteness of the middle portion of the century was not associated 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 coxcombs, 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 passion of love, the access of jealousy, the transports of maternal tenderness, the instants of superstition, the way in which
