Beyond the toleration of all forms of religion, however, he never went; though he himself added to the literature of deism. Apart from his verses we have from him the posthumous treatise Pensées sur la Religion, probably written early in his life, where the rational case against the concepts of revelation and of miracles is put with a calm and sustained force. Like the rest, he is uncritical in his deism; but, that granted, his reasoning is unanswerable. In talk he was wont to treat the clergy with small respect;[98] and he wrote more denunciatory things concerning them than almost any freethinker of the century.[99] Bayle, Voltaire, and Lucretius were his favourite studies; and as the then crude German literature had no attraction for him, he drew to his court many distinguished Frenchmen, including La Mettrie, Maupertuis, D’Alembert, D’Argens, and above all Voltaire, between whom and him there was an incurable incompatibility of temper and character, and a persistent attraction of force of mind, which left them admiring without respecting each other, and unable to abstain from mutual vituperation. Under Frederick’s vigorous rule all speech was free save such as he considered personally offensive, as Voltaire’s attack on Maupertuis; and after a stormy reign he could say, when asked by Prince William of Brunswick whether he did not think religion one of the best supports of a king’s authority, “I find order and the laws sufficient.... Depend upon it, countries have been admirably governed when your religion had no existence.”[100] Religion certainly had no part in his personality in the ordinary sense of the term. Voltaire was wont to impute to him atheism; when La Mettrie died, the mocker, then at Frederick’s court, remarked that the post of his majesty’s atheist was vacant, but happily the Abbé de Prades was there to fill it. In effect, Frederick professed Voltaire’s own deism; but of all the deists of the time he had least of the religious temperament and most of sheer cynicism.

The attempt of Carlyle to exhibit Frederick as a practical believer is a flagrant instance of that writer’s subjective method. He tells (Hist. of Friedrich, bk. xviii, ch. x) that at the beginning of the battle of Leuthen a column of troops near the king sang a hymn of duty (which Carlyle calls “the sound of Psalms”); that an officer asked whether the singing should be stopped, and that the king said “By no means.” His “hard heart seems to have been touched by it. Indeed, there is in him, in those grim days, a tone (!) as of trust in the Eternal, as of real religious piety and faith, scarcely noticeable elsewhere in his history. His religion—and he had in withered forms a good deal of it, if we will look well—being almost always in a strictly voiceless state, nay, ultra voiceless, or voiced the wrong way, as is too well known.” Then comes the assertion that “a moment after” the king said “to someone, Ziethen probably, ‘With men like these, don’t you think I shall have victory this day!’” Here, with the very spirit of unveracity at work before his eyes, Carlyle plumps for the fable. Yet the story, even if true, would give no proof whatever of religious belief.

In point of fact, Frederick was a much less “religious” deist than Voltaire. He erected no temple to his unloved God. And a perusal of his dialogue of Pompadour and the Virgin (Dialogues des morts) may serve to dispose of the thesis that the German mind dealt reverently and decently with matters which the French mind handled frivolously. That performance outgoes in ribaldry anything of the age in French.

As the first modern freethinking king, Frederick is something of a test case. Son of a man of narrow mind and odious character, he was himself no admirable type, being neither benevolent nor considerate, neither truthful nor generous; and in international politics, after writing in his youth a treatise in censure of Machiavelli, he played the old game of unscrupulous aggression. Yet he was not only the most competent, but, as regards home administration, the most conscientious king of his time. To find him a rival we must go back to the pagan Antonines and Julian, or at least to St. Louis of France, who, however, was rather worsened than bettered by his creed.[101] Henri IV of France, who rivalled him in sagacity and greatly excelled him in human kindness, was far his inferior in devotion to duty.

The effect of Frederick’s training is seen in his final attitude to the advanced criticism of the school of d’Holbach, which assailed governments and creeds with the same unsparing severity of logic and moral reprobation. Stung by the uncompromising attack, Frederick retorts by censuring the rashness which would plunge nations into civil strife because kings miscarry where no human wisdom could avoid miscarriage. He who had wantonly plunged all Germany into a hell of war for his sole ambition, bringing myriads to misery, thousands to violent death, and hundreds of his own soldiers to suicide, could be virtuously indignant at the irresponsible audacity of writers who indicted the whole existing system for its imbecility and injustice. But he did reason on the criticism; he did ponder it; he did feel bound to meet argument with argument; and he left his arguments to the world. The advance on previous regal practice is noteworthy: the whole problem of politics is at once brought to the test of judgment and persuasion. Beside the Christian Georges and the Louis’s of his century, and beside his Christian father, his superiority in judgment and even in some essential points of character is signal. Such was the great deist king of the deist age; a deist of the least religious temper and of no very fine moral material to begin with.

The one contemporary monarch who in any way compares with him in enlightenment, Joseph II of Austria, belonged to the same school. The main charge against Frederick as a ruler is that he did not act up to the ideals of the school of Voltaire. In reply to the demand of the French deists for an abolition of all superstitious teaching, he observed that among the 16,000,000 inhabitants of France at most 200,000 were capable of philosophic views, and that the remaining 15,800,000 were held to their opinions by “insurmountable obstacles.”[102] This, however, had been said by the deists themselves (e.g., d’Holbach, préf. to Christianisme dévoilé); and such an answer meant that he had no idea of so spreading instruction that all men should have a chance of reaching rational beliefs. This attitude was his inheritance from the past. Yet it was under him that Prussia began to figure as a first-rate culture force in Europe.

14. The social vogue of deistic thought could now be traced in much of the German belles-lettres of the time. The young Jakob von Mauvillon (1743–1794), secretary of the King of Poland and author of several histories, in his youth translated from the Latin into French Holberg’s Voyage of Nicolas Klimius (1766), which made the tour of Europe, and had a special vogue in Germany. Later in life, besides translating and writing abundantly and intelligently on matters of economic and military science—in the latter of which he had something like expert status—Mauvillon became a pronounced heretic, though careful to keep his propaganda anonymous.

The most systematic dissemination of the new ideas was that carried on in the periodical published by Christoph Friedrich Nicolai (1733–1811) under the title of The General German Library (founded 1765), which began with fifty contributors, and at the height of its power had a hundred and thirty, among them being Lessing, Eberhard, and Moses Mendelssohn. In the period from its start to the year 1792 it ran to 106 volumes; and it has always been more or less bitterly spoken of by later orthodoxy as the great library of that movement. Nicolai, himself an industrious and scholarly writer, produced among many other things a satirical romance famous in its day, the Life and Opinions of Magister Sebaldus Nothanker, ridiculing the bigots and persecutors the type of Klotz, the antagonist of Lessing, and some of Nicolai’s less unamiable antagonists,[103] as well as various aspects of the general social and literary life of the time. To Nicolai is fully due the genial tribute paid to him by Heine,[104] were it only for the national service of his “Library.” Its many translations from the English and French freethinkers, older and newer, concurred with native work to spread a deistic rationalism, labelled Aufklärung, or enlightenment, through the whole middle class of Germany.[105] Native writers in independent works added to the propaganda. Andreas Riem (1749–1807), a Berlin preacher, appointed by Frederick a hospital chaplain,[106] wrote anonymously against priestcraft as no other priest had yet done. “No class of men,” he declared, in language perhaps echoed from his king, “has ever been so pernicious to the world as the priesthood. There were laws at all times against murderers and bandits, but not against the assassin in the priestly garb. War was repelled by war, and it came to an end. The war of the priesthood against reason has lasted for thousands of years, and it still goes on without ceasing.”[107] Georg Schade (1712–1795), who appears to have been one of the believers in the immortality of animals, and who in 1770 was imprisoned for his opinions in the Danish island of Christiansœ, was no less emphatic, declaring, in a work on Natural Religion on the lines of Tindal (1760), that “all who assert a supernatural religion are godless impostors.”[108] Constructive work of great importance, again, was done by J. B. Basedow (1723–1790), who early became an active deist, but distinguished himself chiefly as an educational reformer, on the inspiration of Rousseau’s Émile,[109] setting up a system which “tore education away from the Christian basis,”[110] and becoming in virtue of that one of the most popular writers of his day. It is latterly admitted even by orthodoxy that school education in Germany had in the seventeenth century become a matter of learning by rote, and that such reforms as had been set up in some of the schools of the Pietists had in Basedow’s day come to nothing.[111] As Basedow was the first to set up vigorous reforms, it is not too much to call him an instaurator of rational education, whose chief fault was to be too far ahead of his age. This, with the personal flaw of an unamiable habit of wrangling in all companies, caused the failure of his “Philanthropic Institute,” established in 1771, on the invitation of the Prince of Dessau, to carry out his educational ideals. Quite a number of other institutions, similarly planned, after his lead, by men of the same way of thinking, as Canope and Salzmann, in the same period, had no better success.

Goethe, who was clearly much impressed by Basedow, and travelled with him, draws a somewhat antagonistic picture of him on retrospect (Wahrheit und Dichtung, B. xiv). He accuses him in particular of always obtruding his anti-orthodox opinions; not choosing to admit that religious opinions were being constantly obtruded on Basedow. Praising Lavater for his more amiable nature, Goethe reveals that Lavater was constantly propounding his orthodoxy. Goethe, in fine, was always lenient to pietism, in which he had been brought up, and to which he was wont to make sentimental concessions. He could never forget his courtly duties towards the established convention, and so far played the game of bigotry. Hagenbach notes (i, 298, note), without any deprecation, that after Basedow had published in 1763–1764 his Philalethie, a perfectly serious treatise on natural as against revealed religion, one of the many orthodox answers, that by Pastor Goeze, so inflamed against him the people of his native town of Hamburg that he could not show himself there without danger. And this is the man accused of “obtruding his views.” Baur is driven, by way of disparagement of Basedow and his school, to censure their self-confidence—precisely the quality which, in religious teachers with whom he agreed, he as a theologian would treat as a mark of superiority. Baur’s attack on the moral utilitarianism of the school is still less worthy of him. (Gesch. der christl. Kirche, iv, 595–96). It reads like an echo of Kahnis (as cited, p. 46 sq.).

Yet another influential deist was Johann August Eberhard (1739–1809), for a time a preacher at Charlottenburg, but driven out of the Church for the heresy of his New Apology of Sokrates; or the Final Salvation of the Heathen (1772).[112] The work in effect placed Sokrates on a level with Jesus,[113] which was blasphemy.[114] But the outcry attracted the attention of Frederick, who made Eberhard a Professor of Philosophy at Halle, where later he opposed the idealism of both Kant and Fichte. Substantially of the same school was the less pronouncedly deistic cleric Steinbart,[115] author of a utilitarian System of Pure Philosophy, or Christian doctrine of Happiness, now forgotten, who had been variously influenced by Locke and Voltaire.[116] Among the less heterodox but still rationalizing clergy of the period were J. J. Spalding, author of a work on The Utility of the Preacher’s Office, a man of the type labelled “Moderate” in the Scotland of the same period, and as such antipathetic to emotional pietists;[117] and Zollikofer, of the same school—both inferribly influenced by the deism of their day. Considerably more of a rationalist than these was the clergyman W. A. Teller (1734–1804), author of a New Testament Lexicon, who reached a position virtually deistic, and intimated to the Jews of Berlin that he would receive them into his church on their making a deistic profession of faith.[118]
