Although there is no consensus about the exact span of time that corresponds to the American Enlightenment, it is safe to say that it occurred during the eighteenth century among thinkers in British North America and the early United States and was inspired by the ideas of the British and French Enlightenments. Based on the metaphor of bringing light to the Dark Age, the Age of the Enlightenment (Siècle des lumières in French and Aufklärung in German) shifted allegiances away from absolute authority, whether religious or political, to more skeptical and optimistic attitudes about human nature, religion and politics. In the American context, thinkers such as Thomas Paine, James Madison, Thomas Jefferson, John Adams and Benjamin Franklin invented and adopted revolutionary ideas about scientific rationality, religious toleration and experimental political organization—ideas that would have far-reaching effects on the development of the fledgling nation. Some coupled science and religion in the notion of deism; others asserted the natural rights of man in the anti-authoritarian doctrine of liberalism; and still others touted the importance of cultivating virtue, enlightened leadership and community in early forms of republican thinking. At least six ideas came to punctuate American Enlightenment thinking: deism, liberalism, republicanism, conservatism, toleration and scientific progress. Many of these were shared with European Enlightenment thinkers, but in some instances took a uniquely American form.
Although distinctive features arose in the eighteenth-century American context, much of the American Enlightenment was continuous with parallel experiences in British and French society. Four themes recur in both European and American Enlightenment texts: modernization, skepticism, reason and liberty. Modernization means that beliefs and institutions based on absolute moral, religious and political authority (such as the divine right of kings and the Ancien Régime) will become increasingly eclipsed by those based on science, rationality and religious pluralism. Many Enlightenment thinkers—especially the French philosophes, such as Voltaire, Rousseau and Diderot—subscribed to some form of skepticism, doubting appeals to miraculous, transcendent and supernatural forces that potentially limit the scope of individual choice and reason. Reason that is universally shared and definitive of the human nature also became a dominant theme in Enlightenment thinkers’ writings, particularly Immanuel Kant’s “What is Enlightenment?” and his Groundwork of the Metaphysics of Morals. The fourth theme, liberty and rights assumed a central place in theories of political association, specifically as limits state authority originating prior to the advent of states (that is, in a state of nature) and manifesting in social contracts, especially in John Locke’s Second Treatise on Civil Government and Thomas Jefferson’s drafts of the Declaration of Independence.

Read this excerpt from the Declaration of Independence (1776):
When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature’s God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.–That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, –That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.–Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government. The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these States. To prove this, let Facts be submitted to a candid world.
