violent shift - “from citizen to citizen as equals”? The Church was merely one of many institutions that had sat massively, reliably, comfortably (and greedily) between people and power. Luther, it later emerged, was not alone. An era of awkward answers had begun. The Prussian astronomer Nicolaus Copernicus, for instance, had preceded Luther by a couple of decades with his own questioning of the unquestionable. “Those who know that the consensus of many centuries has sanctioned the idea that the earth remains at rest while the heavens move around it would regard it as an insane pronouncement if I said the opposite,” he wrote. Machiavelli, Galileo, Erasmus, a growing list of great, transformative names - they were all working away in this same questioning spirit. Their insane pronouncements, when proven true, opened the way to still further insights. The Enlightenment had begun. The old power centers acted almost as if nothing had changed; maybe they believed nothing would ever need to. “What was, still is,” the Catholic Church pronounced confidently (and absurdly) at the Council of Trent in response to Luther’s Reformation. But there was no turning back. As the German philosopher Immanuel Kant wrote, the motto of the era could best be summarized as: Dare to know! “The Enlightenment,” he explained, “requires nothing but freedom.”” This, it emerged, was a hell of an expensive requirement. 4, In the years after Luther’s 95 Theses, Europe was torn apart.
