In his middle to late thirties (over the years 1679-85), Gottfried Wilhelm Leibniz spent more than three years in his visits to a silver mining region in the Harz mountains. He believed he could devise new and more efficient ways of pumping water out of the deep shafts, enabling miners to dig even deeper and extract more silver from the earth. Had he succeeded, he would have doubled his salary and freed himself from the drudgery of his service to the House of Brunswick.
But this effort wasn't just a ploy to gain financial independence. He had a bigger plan in mind. Indeed, Leibniz always had bigger plans in mind. He was born into the aftermath of the Thirty Years' war and he believed his genius could go some way toward healing Europe's countless fractures. And so he wrote theological works aimed at convincing Catholics and Protestants that the differences among them were not so big after all; he wrote political works advocating for unity across Christendom; and he wrote logical and scientific works aimed at truth, or course, but also aimed indirectly at supplying a common foundation to learned societies across Europe.
The project in the Harz was meant to play an instrumental role in these ambitions. Had it succeeded, the money would have gone to support one of Leibniz's greatest dreams: the development of a characteristica universalis, a rigorous calculus of pure concepts that would itself be a lasting theoretical framework for constructive dialogue among scientists, philosophers, theologians, and politicians across the planet and, indeed, for all time.
