A more direct cause was found about the middle of the century in the influence of the French refugees and others, whom Frederick the Great invited to his court. Not only were Voltaire and Diderot visitors, but several writers of worse fame, La Mettrie, D’Argens, Maupertuis,(670) who possessed their faults without their mental power, were constant residents. Their philosophy and unbelief were the miniature of that which we have detailed in France. They created an antichristian atmosphere about the court, and in the upper classes of Berlin; and even minds that were attempting to create a native literature, and to improve the critical standard of literary taste, were partially influenced by means of it.(671) We have now seen the state of the German mind in reference to theology at the beginning of the eighteenth century, and the three new influences which were introduced into it in the interval between 1720 and 1760. The dogmatic tendency became transformed by the Wolffian philosophy; the pietistic retired from a public movement into the privacy of life; while the minds of men were awakened to inquiry by the suggestions of the English deists, or the restless and hopeful tone of the French mind. It was a moment of transition; the streaks of twilight before the dawn. Yet the signs of a change were so slight, that few could as yet discern the coming of a crisis, none predict its form. We may now proceed to give the history of the theological movement which sprang up, commonly called Rationalism. It admits of natural division into three parts. The first, a period destructive in its tendency, extending to a little later than the end of the century, exhibits the gradual growth of the system, and its spread over every department of theology. The second, reconstructive in character, the re-establishment of harmony between faith and reason, extends till the publication of Strauss’s celebrated work on the Life of Christ in 1835; the third, containing the divergent tendencies which have created permanent schools, reaches to the present time.(672) In all alike the harmony of faith and reason was sought: but in the first it was attained by sacrificing faith to reason; in the second and third, by seeking for their unity, or by separating their spheres. A distinguished name stands at the commencement of each period, representing the mind whose speculations were most influential in giving form to the movements. Semler inaugurated the destructive movement; Schleiermacher, the constructive; and Strauss precipitated the final forms which theological parties have assumed. In the present lecture we shall treat only of the first two of these movements.
