As we have said before, the immediate force of speculative literature hangs on practical opportuneness. It was not merely because Bacon and Hobbes and Locke had written certain books, that the Encyclopædists, who took up their philosophic succession, inevitably became a powerful political party, and multiplied their adherents in an increasing proportion as the years went on. From various circumstances the attack acquired a significance and a weight in France which it had never possessed in England. For one thing, physical science had in the interval taken immense strides. This both dwarfed the sovereignty of theology and theological metaphysics, and indirectly disposed men's minds for non-theological theories of moral as well as of physical phenomena. In France, again, the objects of the attack were inelastic and unyielding. Political speculation in England followed, and did not precede, political innovation and reform. In France its light played round institutions which were too deeply rooted in absolutism and privilege to be capable of substantial modification. Deism was comparatively impotent against the Church of England, first, because it was an intellectual movement, and not a social one; second, because the constitutional doctrines of the church were flexible. Deism in the hands of its French propagators became connected with social liberalism, because the Catholic church in those days was identified with all the ideas of repression. And the tendencies of deism in France grew more violently destructive, not only because religious superstition was grosser, but because that superstition was incorporated in a strong and inexpansible social structure.

"It would be a mistake," wrote that sagacious and well-informed observer, D'Argenson, so early as 1753, "to attribute the loss of religion in France to the English philosophy, which has not gained more than a hundred philosophers or so in Paris, instead of setting it down to the hatred against the priests, which goes to the very last extreme. All minds are turning to discontent and disobedience, and everything is on the high road to a great revolution, both in religion and in government. And it will be a very different thing to that rude Reformation, a medley of superstition and freedom, which came to us from Germany in the sixteenth century! As our nation and our century are enlightened in so very different a fashion, they will go whither they ought to go; they will banish every priest, all priesthood, all revelation, all mystery." This, however, only represents the destructive side of the vast change which D'Argenson then foresaw, six-and-thirty years before its consummation. That change had also a constructive side. If one of its elements was hate, another and more important element was hope. This constructive and reforming spirit which made its way in the intelligence of the leading men in France from 1750 to 1789, was represented in the encyclopædic confederation, and embodied in their forty folios. And, to return to our first point, it was directly and inseparably associated with the philosophy of Bacon and Locke. What is the connection between their speculations and a vehement and energetic spirit of social reform? We have no space here to do more than barely hint the line of answer.

The broad features of the speculative revolution of which the Encyclopædia was the outcome, lie on the surface of its pages and cannot be mistaken. The transition from Descartes to Newton meant the definite substitution of observation for hypothesis. The exaltation of Bacon meant the advance from supernatural explanations to explanations from experience. The acceptance and development of the Lockian psychology meant the reference of our ideas to bodily sensations, and led men by what they thought a tolerably direct path to the identification of mind with functions of matter. We need not here discuss the philosophical truth or adequateness of these ways of considering the origin and nature of knowledge, or the composition of human character. All that now concerns us is to mark their tendency. That tendency clearly is to expel Magic as the decisive influence among us, in favour of ordered relations of cause and effect, only to be discovered by intelligent search. The universe began to be more directly conceived as a group of phenomena that are capable of rational and connected explanation. Then, the wider the area of law, the greater is man's consciousness of his power of controlling forces, and securing the results that he desires. Objective interests and their conditions acquire an increasing preponderance in his mind. On the other hand, as the limits of science expand, so do the limits of nescience become more definite. The more we know of the universal order, the more are we persuaded, however gradually and insensibly, that certain matters which men believed themselves to know outside of this phenomenal order, are in truth inaccessible by those instruments of experience and observation to which we are indebted for other knowledge. Hence, a natural inclination to devote our faculty to the forces within our control, and to withdraw it from vain industry about forces—if they be forces—which are beyond our control and beyond our apprehension. Thus man becomes the centre of the world to himself, nature his servant and minister, human society the field of his interests and his exertions. The sensational psychology, again, whether scientifically defensible or not, clearly tends to heighten our idea of the power of education and institutions upon character. The more vividly we realise the share of external impressions in making men what they are, the more ready we shall be to concern ourselves with external conditions and their improvement. The introduction of the positive spirit into the observation of the facts of society was not to be expected until the Cartesian philosophy, with its reliance on inexplicable intuitions and its exaggeration of the method of hypothesis, had been laid aside.

Diderot struck a key-note of difference between the old Catholic spirit and the new social spirit, between quietist superstition and energetic science, in the casual sentence in his article on alms-houses and hospitals: "It would be far more important to work at the prevention of misery, than to multiply places of refuge for the miserable."

It is very easy to show that the Encyclopædists had not established an impregnable scientific basis for their philosophy. Anybody can now see that their metaphysic and psychology were imperfectly thought out. The important thing is that their metaphysic and psychology were calculated, notwithstanding all their superficialities, to inspire an energetic social spirit, because they were pregnant with humanistic sentiment. To represent the Encyclopædia as the gospel of negation and denial is to omit four-fifths of its contents. Men may certainly, if they please, describe it as merely negative work, for example, to denounce such institutions as examination and punishment by Torture (See Question, Peine), but if so, what gospel of affirmation can bring better blessings?[159] If the metaphysic of these writers had been a thousandfold more superficial than it was, what mattered that, so long as they had vision for every one of the great social improvements on which the progress and even the very life of the nation depended? It would be obviously unfair to say that reasoned interest in social improvement is incompatible with a spiritualistic doctrine, but we are justified in saying that energetic faith in possibilities of social progress has been first reached through the philosophy of sensation and experience.

In describing the encyclopædic movement as being, among other things, the development of political interest under the presiding influence of a humanistic philosophy, we are using the name of politics in its widest sense. The economic conditions of a country, and the administration of its laws, are far more vitally related to its well-being than the form of its government. The form of government is indeed a question of the first importance, but then this is owing in a paramount degree to the influence which it may have upon the other two sets of elements in the national life. Form of government is like the fashion of a man's clothes; it may fret or may comfort him, may be imposing or mean, may react upon his spirits to elate or depress them. In either case it is less intimately related to his welfare than the state of his blood and tissues. In saying, then, that the Encyclopædists began a political work, what is meant is that they drew into the light of new ideas, groups of institutions, usages, and arrangements which affected the real well-being and happiness of France, as closely as nutrition affected the health and strength of an individual Frenchman. It was the Encyclopædists who first stirred opinion in France against the iniquities of colonial tyranny and the abominations of the slave trade. They demonstrated the folly and wastefulness and cruelty of a fiscal system that was eating the life out of the land. They protested in season and out of season against arrangements which made the administration of justice a matter of sale and purchase. They lifted up a strong voice against the atrocious barbarities of an antiquated penal code. It was this band of writers, organised by a harassed man of letters, and not the nobles swarming round Lewis XV., nor the churchmen singing masses, who first grasped the great principle of modern society, the honour that is owed to productive industry. They were vehement for the glories of peace, and passionate against the brazen glories of war.[160]

We are not to suppose that the Encyclopædia was the originating organ of either new methods or new social ideas. The exalted and peculiarly modern views about peace, for instance, were plainly inspired from the writings of the Abbé Saint Pierre (1658-1743)—one of the most original spirits of the century, who deserves to be remembered among other good services as the inventor of the word bienfaisance. Again, in the mass of the political articles we feel the immense impulse that was given to sociological discussion by the Esprit des Lois. Few questions are debated here, which Montesquieu had not raised, and none are debated without reference to Montesquieu's line of argument. The change of which we are conscious in turning from the Esprit des Lois to the Encyclopædia is that political ideas have been grasped as instruments. Philosophy has become patriotism. The Encyclopædists advanced with grave solicitude to the consideration of evils, to which the red-heeled parasites of Versailles were insolently and incorrigibly blind.

The articles on Agriculture, for example, are admirable alike for the fulness and precision with which they expose the actual state of France; for the clearness with which they trace its deplorable inadequateness back to the true sources; and for the strong interest and sympathy in the subject, which they both exhibit and inspire. If now and again the touch is too idyllic, it was still a prodigious gain to let the country know in a definite way that of the fifty million arpents of cultivable land in the realm, more than one quarter lay either unbroken or abandoned. And it was a prodigious gain to arouse the attention of the general public to the causes of the forced deterioration of French agriculture, namely, the restrictions on trade in grain, the arbitrariness of the imposts, and the flight of the population to the large towns. Then the demonstration, corroborated in the pages of the Encyclopædia by the two patriotic vaunts of contemporary English writers, of the stimulus given to agriculture by our system of free exports, contained one of the most useful lessons that the French had to learn.

Again, there are some abuses which cannot be more effectively attacked, than by a mere statement of the facts in the plainest and least argumentative terms. The history of such an impost as the tax upon salt (Gabelle), and a bold outline of the random and incongruous fashions in which it was levied, were equivalent to a formal indictment. It needed no rhetoric nor discussion to heighten the harsh injustice of the rule that "persons who have changed domicile are still taxed for a certain time in the seat of their former abode, namely, farmers and labourers for one year, and all other tax-payers for two years, provided the parish to which they have removed is within the same district; and if otherwise, then farmers to pay for two years, and other persons for three years" (Taille). Thus a man under the given circumstances would have to pay double taxes for three years as a penalty for changing his dwelling. We already hear the murmur of the cahiers of five-and-twenty years later in the account of the transports of joy with which the citizens of Lisieux saw the taille proportionelle established (1718), and how numerous other cities sent up prayers that the same blessing might be conferred on them. "Reasons that it is not for us to divine, caused the rejection of these demands; so hard is it to do a good act, which everybody talks about, much more in order to seem to desire it, than from any intention of really doing it.... To illustrate the advantages of this plan, the impost of 1718 with all arrears for five years was discharged in twelve months without needless cost or dispute. By an extravagance more proper than any other to degrade humanity, the common happiness made malcontents of all that class whose prosperity depends on the misery of others,"—that is the privileged class.[161]

It is no innate factiousness, as flighty critics of French affairs sometimes imply, that has made civil equality the passion of modern France. The root of this passion is an undying memory of the curse that was inflicted on its citizens, morally and materially, by the fiscal inequalities of the old régime. The article, Privilegé, urges the desirableness of inquiring into the grounds of the vast multitude of fiscal exemptions, and of abolishing all that were no longer associated with the performance of real and useful service. "A bourgeois," says the writer, anticipating a cry that was so soon to ring through the land, "a bourgeois in comfortable circumstances, and who could himself pay half of the taille of a whole parish, if it were imposed in its due proportion,—on payment of the amount of his taxes for one or for two years, and often for less; without birth, education, or talents, buys a place in a local salt office, or some useless charge at court, or in the household of some prince.... This man proceeds to enjoy in the public eye all the exemptions possessed by the nobility and the high magistracy.... From such an abuse of privileges spring two very considerable evils: the poorer part of the citizens are always burdened beyond their strength, though they are the most useful to the State, since this class is composed of those who cultivate the land, and procure a subsistence for the upper classes; the other evil is that privileges disgust persons of education and talent with the idea of entering the magistracy or other professions demanding labour and application, and lead them to prefer small posts and paltry offices." And so forth, with a gravity and moderation, that were then common in political discussion in France. It gradually disappeared in 1789, when it was found that the privileged orders, even at that time, in their cahiers steadily demanded the maintenance of every one of their most odious and iniquitous rights.[162]
