As to Wolff’s rationalistic influence see Cairns, Unbelief in the Eighteenth Century, 1881, p. 173; Pusey, pp. 115–19; Pünjer, p. 529; Lechler, pp. 448–49. “It cannot be questioned that, in his philosophy, the main stress rests upon the rational” (Kahnis, as cited, p. 28). “Francke and Lange (pietists) ... saw atheism and corruption of manners springing up from Wolff’s school” (before his exile). Id. p. 113. Wolff’s chief offence lay in stressing natural religion, and in indicating, as Tholuck observes, that that could be demonstrated, whereas revealed religion could only be believed (Abriss, p. 18). He greatly pleased Voltaire by the dictum that men ought to be just even though they had the misfortune to be atheists. It is noted by Tholuck, however (Abriss, as cited, p. 11, note), that the decree for Wolff’s expulsion was inspired not by his theological colleagues but by two military advisers of the king. Tholuck’s own criticism resolves itself into a protest against Wolff’s predilection for logical connection in his exposition. The fatal thing was that Wolff accustomed German Christians to reason.
9. Even before the generation of active pressure from English and French deism there were clear signs that rationalism had taken root in German life. On the impulse set up by the establishment of the Grand Lodge at London in 1717, Freemasonic lodges began to spring up in Germany, the first being founded at Hamburg in 1733.[67] The deism which in the English lodges was later toned down by orthodox reaction was from the first pronounced in the German societies, which ultimately passed on the tradition to the other parts of the Continent. But the new spirit was not confined to secret societies. Wolffianism worked widely. In the so-called Wertheim Bible (1735) Johann Lorenz Schmid, in the spirit of the Leibnitz-Wolffian theology, “undertook to translate the Bible, and to explain it according to the principle that in revelation only that can be accepted as true which does not contradict the reason.”[68] This of course involved no thorough-going criticism; but the spirit of innovation was strong enough in Schmid to make him undermine tradition at many points, and later carried him so far as to translate Tindal’s Christianity as old as Creation. So far was he in advance of his time that when his Wertheim Bible was officially condemned throughout Germany he found no defenders.[69] The Wolffians were in comparison generally orthodox; and another writer of the same school, Martin Knutzen, professor at Königsberg (1715–1751), undertook in a youthful thesis De æternitate mundi impossibili (1735) to rebut the old Averroïst doctrine, revived by modern science, of the indestructibility of the universe. A few years later (1739) he published a treatise entitled The Truth of Christianity Demonstrated by Mathematics, which succeeded as might have been expected.
10. To the same period belong the first activities of Johann Christian Edelmann (1698–1767), one of the most energetic freethinkers of his age. Trained philosophically at Jena under the theologian Budde, a bitter opponent of Wolff, and theologically in the school of the Pietists, he was strongly influenced against official orthodoxy through reading the Impartial History of the Church and of Heretics, by Gottfried Arnold, an eminently anti-clerical work, which nearly always takes the side of the heretics.[70] In the same heterodox direction he was swayed by the works of Dippel. At this stage Edelmann produced his Unschuldige Wahrheiten (“Innocent Truths”), in which he takes up a pronouncedly rationalist and latitudinarian position, but without rejecting “revelation”; and in 1736 he went to Berleburg, where he worked on the Berleburg translation of the Bible, a Pietist undertaking, somewhat on the lines of Dippel’s mystical doctrine, in which a variety of incredible Scriptural narratives, from the six days’ creation onwards, are turned to mystical purpose.[71] In this occupation Edelmann seems to have passed some years. Gradually, however, he came more and more under the influence of the English deists; and he at length withdrew from the Pietist camp, attacking his former associates for the fanaticism into which their thought was degenerating. It was under the influence of Spinoza, however, that he took his most important steps. A few months after meeting with the Tractatus he began (1740) the first part of his treatise Moses mit aufgedecktem Angesichte (“Moses with unveiled face”), an attack at once on the doctrine of inspiration and on that of the Mosaic authorship of the Pentateuch. The book was intended to consist of twelve parts; but after the appearance of three it was prohibited by the imperial fisc, and the published parts burned by the hangman at Hamburg and elsewhere. Nonetheless, Edelmann continued his propaganda, publishing in 1741 or 1742 The Divinity of Reason,[72] and in 1741 Christ and Belial. In 1749 or 1750 his works were again publicly burned at Frankfurt by order of the imperial authorities; and he had much ado to find anywhere in Germany safe harbourage, till he found protection under Frederick at Berlin, where he died in 1767.
Edelmann’s teaching was essentially Spinozist and pantheistic,[73] with a leaning to the doctrine of metempsychosis. As a pantheist he of course entirely rejected the divinity of Jesus, pronouncing inspiration the appanage of all; and the gospels were by him dismissed as late fabrications, from which the true teachings of the founder could not be learned; though, like nearly all the freethinkers of that age, he estimated Jesus highly.[74] A German theologian complains, nevertheless, that he was “more just toward heathenism than toward Judaism; and more just toward Judaism than toward Christianity”; adding: “What he taught had been thoroughly and ingeniously said in France and England; but from a German theologian, and that with such eloquent coarseness, with such a mastery in expatiating in blasphemy, such things were unheard of.”[75] The force of Edelmann’s attack may be gathered from the same writer’s account of him as a “bird of prey” who rose to a “wicked height of opposition, not only against the Lutheran Church, but against Christianity in general.”
11. Even from decorous and official exponents of religion, however, there came “naturalistic” and semi-rationalistic teaching, as in the Reflections on the most important truths of religion[76] (1768–1769) of J. F. W. Jerusalem, Abbot of Marienthal in Brunswick, and later of Riddagshausen (1709–1789). Jerusalem had travelled in Europe, and had spent two years in Holland and one in England, where he studied the deists and their opponents. “In England alone,” he declared, “is mankind original.”[77] Though really written by way of defending Christianity against the freethinkers, in particular against Bolingbroke and Voltaire,[78] the very title of his book is suggestive of a process of disintegration; and in it certain unedifying Scriptural miracles are actually rejected.[79] It was probably this measure of adaptation to new needs that gave it its great popularity in Germany and secured its translation into several other languages. Goethe called him a “freely and gently thinking theologian”; and a modern orthodox historian of the Church groups him with those who “contributed to the spread of Rationalism by sermons and by popular doctrinal and devotional works.”[80] Jerusalem was, however, at most a semi-rationalist, taking a view of the fundamental Christian dogmas which approached closely to that of Locke.[81] It was, as Goethe said later, the epoch of common sense; and the very theologians tended to a “religion of nature.”[82]
12. Alongside of home-made heresy there had come into play a new initiative force in the literature of English deism, which began to be translated after 1740,[83] and was widely circulated till, in the last third of the century, it was superseded by the French. The English answers to the deists were frequently translated likewise, and notoriously helped to promote deism[84]—another proof that it was not their influence that had changed the balance of activity in England. Under a freethinking king, even clergymen began guardedly to accept the deistic methods; and the optimism of Shaftesbury began to overlay the optimism of Leibnitz;[85] while a French scientific influence began with La Mettrie,[86] Maupertuis, and Robinet. Even the Leibnitzian school, proceeding on the principle of immortal monads, developed a doctrine of the immortality of the souls of animals[87]—a position not helpful to orthodoxy. There was thus a general stirring of doubt among educated people,[88] and we find mention in Goethe’s Autobiography of an old gentleman of Frankfort who avowed, as against the optimists, “Even in God I find defects (Fehler).”[89]
On the other hand, there were instances in Germany of the phenomenon, already seen in England in Newton and Boyle, of men of science devoting themselves to the defence of the faith. The most notable cases were those of the mathematician Euler and the biologist von Haller. The latter wrote Letters (to his Daughter) On the most important Truths of Revelation (1772)[90] and other apologetic works. Euler in 1747 published at Berlin, where he was professor, his Defence of Revelation against the Reproaches of Freethinkers;[91] and in 1769 his Letters to a German Princess, of which the argument notably coincides with part of that of Berkeley against the freethinking mathematicians. Haller’s position comes to the same thing. All three men, in fact, grasped at the argument of despair—the inadequacy of the human faculties to sound the mystery of things; and all alike were entirely unable to see that it logically cancelled their own judgments. Even a theologian, contemplating Haller’s theorem of an incomprehensible omnipotence countered in its merciful plan of salvation by the set of worms it sought to save, comments on the childishness of the philosophy which confidently described the plans of deity in terms of what it declared to be the blank ignorance of the worms in question.[92] Euler and Haller, like some later men of science, kept their scientific method for the mechanical or physical problems of their scientific work, and brought to the deepest problems of all the self-will, the emotionalism, and the irresponsibility of the ignorant average man. Each did but express in his own way the resentment of the undisciplined mind at attacks upon its prejudices; and Haller’s resort to poetry as a vehicle for his religion gives the measure of his powers on that side. Thus in Germany as in England the “answer” to the freethinkers was a failure. Men of science playing at theology and theologians playing at science alike failed to turn the tide of opinion, now socially favoured by the known deism of the king. German orthodoxy, says a recent Christian apologist, fell “with a rapidity reminding one of the capture of Jericho.”[93] Goethe, writing of the general attitude to Christianity about 1768, sums up that “the Christian religion wavered between its own historic-positive base and a pure deism, which, grounded on morality, was in turn to re-establish ethics.”[94]
Frederick’s attitude, said an early Kantian, had had “an almost magical influence” on popular opinion (Willich, Elements of the Critical Philosophy, 1798, p. 2). With this his French teachers must have had much to do. Lord Morley pronounces (Voltaire, 4th ed. p. 123) that French deism “never made any impression on Germany,” and that “the teaching of Leibnitz and Wolff stood like a fortified wall against the French invasion.” This is contradicted by much German testimony; in particular by Lange’s (Gesch. des Mater. i, 318), though he notes that French materialism could not get the upper hand. Laukhard, who expressed the highest admiration for Tindal, as having wholly delivered him from dogmatism, avowed that Voltaire, whom everybody read, had perhaps done more harm to priest religion than all the books of the English and German deists together (Leben, 1792–1802, Th. i, p. 268).
Tholuck gravely affirms (Abriss, p. 33) that the acquaintance with the French “deistery and frivolity” in Germany belongs to a “somewhat later period than that of the English.” Naturally it did. The bulk of the English deistic literature was printed before the printing of the French had begun! French MSS. would reach German princes, but not German pastors. But Tholuck sadly avows that the French deism (of the serious and pre-Voltairean portions of which he seems to have known nothing) had a “frightful” influence on the upper classes, though not on the clergy (p. 34). Following him, Kahnis writes (Internal History, p. 41) that “English and French Deism met with a very favourable reception in Germany—the latter chiefly in the higher circles, the former rather among the educated middle classes.” (He should have added, “the younger theologians.”) Baur, even in speaking disparagingly of the French as compared with the English influence, admits (Lehrbuch der Dogmengeschichte, 2te Aufl. p. 347) that the former told upon Germany. Cp. Tennemann, Bohn. tr. pp. 385, 388. Hagenbach shows great ignorance of English deism, but he must have known something of German; and he writes (tr. p. 57) that “the imported deism,” both English and French, “soon swept through the rifts of the Church, and gained supreme control of literature.” Cp. pp. 67–68. See Croom Robertson’s Hobbes, pp. 225–26, as to the persistence of a succession of Hobbes and Locke in Germany in the teeth of the Wolffian school, which soon lost ground after 1740. It is further noteworthy that Brucker’s copious Historia Critica Philosophiæ (1742–44), which as a mere learned record has great merit, and was long the standard authority in Germany, gives great praise to Locke and little space to Wolff. (See Enfield’s abstract, pp. 614, 619 sq.) The Wolffian philosophy, too, had been rejected and disparaged by both Herder and Kant—who were alike deeply influenced by Rousseau—in the third quarter of the century; and was generally discredited, save in the schools, when Kant produced the Critique of Pure Reason. See below, pp. 337, 345.
13. Frederick, though reputed a Voltairean freethinker par excellence, may be claimed for Germany as partly a product of the rationalizing philosophy of Wolff. In his first letter to Voltaire, written in 1736, four years before his accession, he promises to send him a translation he has had made of the “accusation and the justification” of Wolff, “the most celebrated philosopher of our days, who, for having carried light into the darkest places of metaphysics, and for having treated the most difficult matters in a manner no less elevated than precise and clear, is cruelly accused of irreligion and atheism”; and he speaks of getting translated Wolff’s Treatise of God, the Soul, and the World. When he became a thoroughgoing freethinker is not clear, for Voltaire at this time had produced no explicit anti-Christian propaganda. At first the new king showed himself disposed to act on the old maxim that freethought is bad for the common people. In 1743–44 he caused to be suppressed two German treatises by one Gebhardi, a contributor to Gottsched’s magazines, attacking the Biblical miracles; and in 1748 he sent a young man named Rüdiger to Spandau for six months’ confinement for printing an anti-Christian work by one Dr. Pott.[95] But as he grew more confident in his own methods he extended to men of his own way of thinking the toleration he allowed to all religionists, save insofar as he vetoed the mutual vituperation of the sects, and such proselytizing as tended to create strife. With an even hand he protected Catholics, Greek Christians, and Unitarians, letting them have churches where they would;[96] and when, after the battle of Striegau, a body of Protestant peasantry asked his permission to slay all the Catholics they could find, he answered with the gospel precept, “Love your enemies.”[97]
