AUTHOR’S NOTE
A few days before I started writing this book, a leading candidate for the presidency of the United States was asked on national television whether he believed in the theory of evolution. He shrugged off the question with a dismissive jab of humor. “It’s interesting that that question would even be asked of someone running for president,” he said. “I’m not planning on writing the curriculum for an eighth-grade science book. I’m asking for the opportunity to be president of the United States.”
It was a funny line, but the joke only worked in a specific intellectual context. For the statement to make sense, the speaker had to share one basic assumption with his audience: that “science” was some kind of specialized intellectual field, about which political leaders needn’t know anything to do their business. Imagine a candidate dismissing a question about his foreign policy experience by saying he was running for president and not writing a textbook on international affairs. The joke wouldn’t make sense, because we assume that foreign policy expertise is a central qualification for the chief executive. But science? That’s for the guys in lab coats.
That line has stayed with me since, because the web of events at the center of this book suggests that its basic assumptions are fundamentally flawed. If there is an overarching moral to this story, it is that vital fields of intellectual achievement cannot be cordoned off from one another and relegated to the specialists, that politics can and should be usefully informed by the insights of science. The protagonists of this story lived in a climate where ideas flowed easily between the realms of politics, philosophy, religion, and science. The closest thing to a hero in this book—the chemist, theologian, and political theorist Joseph Priestley—spent his whole career in the space that connects those different fields. But the other figures central to this story—Ben Franklin, John Adams, Thomas Jefferson—suggest one additional reading of the “eighth-grade science” remark. It was anti-intellectual, to be sure, but it was something even more incendiary in the context of a presidential race. It was positively un-American.
In their legendary thirteen-year final correspondence, reflecting back on their collaborations and their feuds, Thomas Jefferson and John Adams wrote 165 letters to each other. In that corpus, Benjamin Franklin is mentioned by name five times, while George Washington is mentioned three times. Their mutual nemesis Alexander Hamilton warrants only two references. By contrast, Priestley, an Englishman who spent only the last decade of his life in the United States, is mentioned fifty-two times. That statistic alone gives some sense of how important Priestley was to the founders, in part because he would play a defining role in the rift and ultimate reconciliation between Jefferson and Adams, and in part because his distinctive worldview had a profound impact on both men, just as it had on Franklin three decades before. Yet today, Priestley is barely more than a footnote in most popular accounts of the revolutionary generation. This book is an attempt to understand how Priestley became so central to the great minds of this period—in the fledgling United States, but also in England and France. It is not so much a biography as it is the biography of one man’s ideas, the links of association and influence that connect him to epic changes in science, belief, and society—as well as to some of the darkest episodes of mob violence and political repression in the history of Britain and the United States.
