Summary and Keywords
The Enlightenment, a complex cultural phenomenon that lasted approximately from the late seventeenth century until the early nineteenth century, contained a dynamic mix of contrary beliefs and epistemologies. Its intellectual coherence arguably came from its distinctive historical sensibility, which was rooted in the notion that advances in the natural sciences had gifted humankind with an exceptional opportunity in the eighteenth century for self-improvement and societal progress. That unifying historical outlook was flexible and adaptable. Consequently, many aspects of the Enlightenment were left open to negotiation at local and transnational levels. They were debated by the philosophes who met in Europe’s coffeehouses, salons, and scientific societies. Equally, they were contested outside of Europe through innumerable cross-cultural exchanges as well as via long-distance intellectual interactions.
America—whether it is understood expansively as the two full continents and neighboring islands within the Western Hemisphere or, in a more limited way, as the territory that now constitutes the United States—played an especially prominent role in the Enlightenment. The New World’s abundance of plants, animals, and indigenous peoples fascinated early modern natural historians and social theorists, stimulated scientific activity, and challenged traditional beliefs. By the eighteenth century, the Western Hemisphere was an important site for empirical science and also for the intersection of different cultures of knowledge. At the same time, European conceptions of the New World as an undeveloped region inhabited by primitive savages problematized Enlightenment theories of universal progress. Comparisons of Native Americans to Africans, Asians, and Europeans led to speculation about the existence of separate human species or races. Similarly, the prevalence and profitability of American slavery fueled new and increasingly scientific conceptions of race. Eighteenth-century analyses of human differences complicated contemporary assertions that all men possessed basic natural rights. Toward the end of the eighteenth century, the American Revolution focused international attention on man’s innate entitlement to life, liberty, and happiness. Yet, in a manner that typified the contradictions and paradoxes of the Enlightenment, the founders of the United States opted to preserve slavery and social inequality after winning political freedom from Britain.
