So what, exactly, was “The Enlightenment”? According to the Princeton historian David A. Bell, it was an intellectual movement roughly spanning the early 18th century through to the French Revolution. In his Spring 2025 Liberties Quarterly piece “The Enlightenment, Then and Now”, Bell charts the Enlightenment as a complex intellectual movement centered in Paris but with hubs across Europe and America. He highlights key figures like Montesquieu, Voltaire, Kant, and Franklin, discussing their contributions to concepts of religious tolerance, free speech, and rationality. In our conversation, Bell addresses criticisms of the Enlightenment, including its complicated relationship with colonialism and slavery, while arguing that its principles of freedom and reason remain relevant today. 5 Key Takeaways * The Enlightenment emerged in the early 18th century (around 1720s) and was characterized by intellectual inquiry, skepticism toward religion, and a growing sense among thinkers that they were living in an "enlightened century." * While Paris was the central hub, the Enlightenment had multiple centers including Scotland, Germany, and America, with thinkers like Voltaire, Rousseau, Kant, Hume, and Franklin contributing to its development. * The Enlightenment introduced the concept of "society" as a sphere of human existence separate from religion and politics, forming the basis of modern social sciences. * The movement had a complex relationship with colonialism and slavery - many Enlightenment thinkers criticized slavery, but some of their ideas about human progress were later used to justify imperialism. * According to Bell, rather than trying to "return to the Enlightenment," modern society should selectively adopt and adapt its valuable principles of free speech, religious tolerance, and education to create our "own Enlightenment." David Avrom Bell is a historian of early modern and modern Europe at Princeton University. His most recent book, published in 2020 by Farrar, Straus and Giroux, is Men on Horseback: The Power of Charisma in the Age of Revolution. Described in the Journal of Modern History as an "instant classic," it is available in paperback from Picador, in French translation from Fayard, and in Italian translation from Viella. A study of how new forms of political charisma arose in the eighteenth and early nineteenth centuries, the book shows that charismatic authoritarianism is as modern a political form as liberal democracy, and shares many of the same origins. Based on exhaustive research in original sources, the book includes case studies of the careers of George Washington, Napoleon Bonaparte, Toussaint Louverture and Simon Bolivar.

Bell is also the author of six previous books. He has published academic articles in both English and French and contributes regularly to general interest publications on a variety of subjects, ranging from modern warfare, to contemporary French politics, to the impact of digital technology on learning and scholarship, and of course French history. A list of his publications from 2023 and 2024 can be found here. His Substack newsletter can be found here. His writings have been translated into French, Spanish, Portuguese, Chinese, Hebrew, Swedish, Polish, Russian, German, Croatian, Italian, Turkish and Japanese. At the History Department at Princeton University, he holds the Sidney and Ruth Lapidus Chair in the Era of North Atlantic Revolutions, and offers courses on early modern Europe, on military history, and on the early modern French empire. Previously, he spent fourteen years at Johns Hopkins University, including three as Dean of Faculty in its School of Arts and Sciences. From 2020 to 2024 he served as Director of the Shelby Cullom Davis Center for Historical Studies at Princeton. He is a member of the American Academy of Arts and Sciences, and a corresponding fellow of the British Academy. Bell's new project is a history of the Enlightenment. A preliminary article from the project was published in early 2022 by Modern Intellectual History. Another is now out in French History.

FULL TRANSCRIPT Andrew Keen: Hello everybody, in these supposedly dark times, the E word comes up a lot, the Enlightenment. Are we at the end of the Enlightenment or the beginning? Was there even an Enlightenment? My guest today, David Bell, a professor of history, very distinguished professor of history at Princeton University, has an interesting piece in the spring issue of It is One of our, our favorite quarterlies here on Keen on America, Bell's piece is The Enlightenment Then and Now, and David is joining us from the home of the Enlightenment, perhaps Paris in France, where he's on sabbatical hard life. David being an academic these days, isn't it? David Bell: Very difficult. I'm having to suffer the Parisian bread and croissant. It's terrible. Andrew Keen: Yeah. Well, I won't keep you too long. Is Paris then, or France? Is it the home of the Enlightenment? I know there are many Enlightenments, the French, the Scottish, maybe even the English, perhaps even the American. David Bell: It's certainly one of the homes of the Enlightenment, and it's probably the closest that the Enlightened had to a center, absolutely. But as you say, there were Edinburgh, Glasgow, plenty of places in Germany, Philadelphia, all those places have good claims to being centers of the enlightenment as well. Andrew Keen: All the same David, is it like one of those sports games in California where everyone gets a medal? David Bell: Well, they're different metals, right, but I think certainly Paris is where everybody went. I mean, if you look at the figures from the German Enlightenment, from the Scottish Enlightenment from the American Enlightenment they all tended to congregate in Paris and the Parisians didn't tend to go anywhere else unless they were forced to. So that gives you a pretty good sense of where the most important center was. Andrew Keen: So David, before we get to specifics, map out for us, because everyone is perhaps as familiar or comfortable with the history of the Enlightenment, and certainly as you are. When did it happen? What years? And who are the leaders of this thing called the Enlightenment? David Bell: Well, that's a big question. And I'm afraid, of course, that if you ask 10 historians, you'll get 10 different answers. Andrew Keen: Well, I'm only asking you, so I only want one answer. David Bell: So I would say that the Enlightenment really gets going around the first couple of decades of the 18th century. And that's when people really start to think that they are actually living in what they start to call an Enlightenment century. There are a lot of reasons for this. They are seeing what we now call the scientific revolution. They're looking at the progress that has been made with that. They are experiencing the changes in the religious sphere, including the end of religious wars, coming with a great deal of skepticism about religion. They are living in a relative period of peace where they're able to speculate much more broadly and daringly than before. But it's really in those first couple of decades that they start thinking of themselves as living in an enlightened century. They start defining themselves as something that would later be called the enlightenment. So I would say that it's, really, really there between maybe the end of the 17th century and 1720s that it really gets started. Andrew Keen: So let's have some names, David, of philosophers, I guess. I mean, if those are the right words. I know that there was a term in French. There is a term called philosoph. Were they the founders, the leaders of the Enlightenment? David Bell: Well, there is a... Again, I don't want to descend into academic quibbling here, but there were lots of leaders. Let me give an example, though. So the year 1721 is a remarkable year. So in the year, 1721, two amazing events happened within a couple of months of each other. So in May, Montesquieu, one of the great philosophers by any definition, publishes his novel called Persian Letters. And this is an incredible novel. Still, I think one of greatest novels ever written, and it's very daring. It is the account, it is supposedly a an account written by two Persian travelers to Europe who are writing back to people in Isfahan about what they're seeing. And it is very critical of French society. It is very of religion. It is, as I said, very daring philosophically. It is a product in part of the increasing contact between Europe and the rest of the world that is also very central to the Enlightenment. So that novel comes out. So it's immediately, you know, the police try to suppress it. But they don't have much success because it's incredibly popular and Montesquieu doesn't suffer any particular problems because... Andrew Keen: And the French police have never been the most efficient police force in the world, have they? D
