This is Part 2 of The Rationalist Option on Communio Sanctorum, History of the Christian Church.In our last episode, we took a look at the genesis of the Enlightenment in England and France. We’ll come back to France a bit later after taking a brief look at the Enlightenment in German and Russia.Germany took a bit longer to join the Enlightenment. That was due in part to the condition of the land following the Thirty Years War. It’s estimated the population shrank from twenty million to just seven after it. There’s also the issue of Germany not really being a country. It was at that time a collection of independent statelets, united by language and culture, but divided between Catholics and Lutherans.The low regard for contemporary culture at that time in Germany is illustrated by the fact that while Newton, Locke, and Voltaire were regarded as heroes in their realms, Germany’s equivalent, Gottfried von Leibniz, was never popular during his lifetime. Yet he was one of the most brilliant men, not just of his day, but of all time. Born in 1646 in Leipzig, Leibniz was the son of a professor of philosophy. He studied law before taking up with a disreputable group of alchemists and worked for the Elector of Mainz.Leibniz came to the attention of the world in 1672, when he was sent on an unofficial ambassadorial mission to Paris. The purpose of this trip was to present Louis XIV with a plan he’d worked out for the invasion of Egypt, by which he hoped to distract the Sun King from ambitions he might have toward Germany. Nothing came of Leibniz’s diplomacy,  although Napoleon seems to have adopted his strategy a century later. In any case, while in Paris, Leibniz took the opportunity to meet with all the luminaries in the foremost city of culture in Europe. He studied mathematics, quickly becoming one of the foremost mathematicians in the world, and made a number of important discoveries, including differential calculus, for which tens of thousands of students have hated him ever since. He also proudly demonstrated an extraordinary mechanical calculator he had built.Leibniz’s interests were so wide-ranging he could never keep his mind on what he was doing. In 1676, he became Court Chancellor of Hanover and was put in charge of the library. But he was more interested in the mines at Harz and spent several years devising increasingly ingenious devices to solve the problem of draining them. He eventually worked for several German states, as well as the cities of Berlin and Vienna, for which he designed a number of civic improvements. In his spare time, he traveled extensively around Europe, meeting other rationalist luminaries, and carrying out his work in mathematics, chemistry, physics, metaphysics, and theology. He produced hardly any books of importance, but his vast correspondence, much of which is still in the process of being edited and published, dwarfed the output of most of his contemporaries; and there cannot have been any subject, however obscure, with which he did not deal, and on which he was not an authority. Leibniz died in 1716, an increasingly marginalized figure, defiantly wearing his long brocade coat and huge wig which had gone out of style decades before.Despite Leibniz’s virtual single-handed attempt to kick-start the German Enlightenment, it didn’t get rolling until the 18th C. Prussia, the largest of the German states, took the lead, as its rulers sought to drag their country into the modern era. Frederick Wilhelm, who came to the throne in 1713, reformed the economy after staying with relatives in the Netherlands.Wilhelm, a careful Lutheran, had no love for Catholic France, but his son, Frederick II, known as Frederick the Great, was a quite different person than his father. Upon his accession to the throne in 1740, he set about building on his father’s practical reforms with a program of cultural renovation. Among his first acts as ruler was to recall from exile Christian Wolff, the
