The Enlightenment

The short analysis

Across the seventeenth and eighteenth centuries, a shifting network of writers, natural philosophers, and salon-goers across Europe and the Atlantic world began insisting that human reason, rather than inherited tradition or revealed religion, was the proper guide to understanding nature and organizing society. The result was less a unified doctrine than a shared set of habits: testing claims against evidence, subjecting institutions to public criticism, and assuming that rational principles could apply universally. The movement drew on the Scientific Revolution's demonstration that careful observation and mathematics could explain the heavens, and it extended that confidence into ethics, politics, and economics. Figures in France, Scotland, Germany, the Netherlands, and the American colonies developed overlapping but distinct traditions, arguing variously for religious toleration, the separation of powers, the foundations of commercial society, and the rights attaching to persons simply by virtue of their humanity. Yet the Enlightenment's relationship with its own ideals was troubled from the start. The same decades that produced declarations of universal rights also saw the expansion of Atlantic slavery, and some thinkers found ways to reconcile the two. That tension, rather than diminishing the period's importance, helps explain why scholars continue to argue about it: the Enlightenment did not simply produce modernity; it produced modernity's contradictions as well.
