The Western world became a beacon of justice, freedom, and prosperity because of the ideas in the Age of Enlightenment, also known as the Age of Reason. This was an intellectual movement in the 17th and 18th centuries that professed a broad array of concepts that North America and Europe consider sacred today. Enlightenment was critical to the American Revolution, allowing the Founding Fathers to produce one of the world’s greatest experiments in human history: The United States of America.

The Age of Enlightenment: A Primer

In 1637, French philosopher Rene Descartes coined the phrase “I think, therefore I am” in his book Discourse on Method. The idea is that his existence cannot be doubted since he is the individual doubting in the first place. Descartes further explored this concept in his 1641 work Meditations on First Philosophy, in which he writes about a cunning Evil Demon who forces him to doubt his existence, but something must be alive in order for it to be deceived.

This simple concept – one that we indeed take for granted today – laid the groundwork for Enlightenment as it sparked the premise that everyone exists in this world because they possess the ability to think. With this truth, people understood that they have independent thought, they should not believe everything they are told, and they can question everything.

Once the Age of Reason progressed, the key objectives behind this movement were clear: the pursuit of happiness and the advancement of reason. But how could these goals be attained? The thinkers of the time, from Francois Voltaire to Immanuel Kant to John Locke, put forward central and rational tenets to achieving these aims: individual liberty, the separation of church and state, religious tolerance, progress, and constitutional government.

Kant had developed a couple mottos for the era of Enlightenment in his essay, Answering the Question: What is Enlightenment: “Dare to know!” and “Have the courage to use your own understanding.” Voltaire also expressed a controversial statement that accentuated the integrity of the freedom of speech: “I disapprove of what you say, but I will defend to the death your right to say it.”

The ideas behind the Enlightenment became prevalent characteristics of art, philosophy, and politics at the time. It was most pronounced in the 19th century’s romanticism when artistic endeavors were emphasized by emotion, individualism, and sentiment.

A Nation Is Born

John Locke is perhaps the most critical person in United States history. The 17th century English philosopher redesigned what government is, writing that it is responsible for protecting and defending the people’s natural rights: life, liberty, and property.

The Founding Fathers understood the power behind Enlightenment. But rather than confine this wisdom to theory, books, and coffeehouses, the titans of the American Revolution wanted to apply the principles to the nation and its people. It was a case of putting theory into practice.

Benjamin Franklin, Thomas Jefferson, Thomas Paine, and James Madison – these men engaged in what was later described as “American Enlightenment.” The attributes in the Age of Reason – from Early Enlightenment to Late Enlightenment – became apparent in the Virginia Declaration of Rights that had been authored by George Mason and adopted by the Virginia Convention of Delegates:

“That all men are by nature equally free and independent, and have certain inherent rights … namely, the enjoyment of life and liberty, with the means of acquiring and possessing property, and pursuing and obtaining happiness and safety.”

The principles later became a part of America’s identity, with the Declaration of Independence stating:

“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.”

American republicanism’s success greatly impacted European politics, particularly the spawn of liberalism and the French Revolution. Nations confronted a new philosophy that would permanently alter their views of the modern world: No longer will kings sit on the throne by the grace of God, but rather governmental power shall rise from the public.

Much like how the Scientific Revolution carved the path for dramatic changes to scientific thought and theory, American Enlightenment paved the way for scientific breakthroughs. Benjamin Franklin’s research on electricity, Cadwallader Colden’s work on town sanitation, and Jared Eliot’s advancement of agriculture – the early days of America were a glimpse of what a free people can accomplish with the most awesome force on the planet: their minds.

A Few Good Men

Who were the leading influential figures of the American Enlightenment? Here are a few good men:

  • Thomas Paine: An English writer and philosopher who is best known for his 1776 pamphlet Common Sense, material that advocated American independence.
  • George Mason: A member of the Virginia House of Burgesses representing Fairfax County who has been considered the father of the Bill of Rights.
  • Benjamin Franklin: A polymath statesman and Founding Father.
  • Thomas Jefferson: The third U.S. president was the author of the Declaration of Independence and made notable contributions – through correspondence – to the Constitution.
  • James Wilson: A legal theorist who acted as an Associate Justice of the U.S. Supreme Court and notable contributor in drafting the Constitution.
  • Samuel Johnson: While not as famous as other Founding Fathers, the clergyman has been described as “a towering intellect of colonial America,” most notably for the first philosophy textbook published in the nation: The Foundation of American Philosophy.

Is Enlightenment Passe?

Despite the age of reason being an instrumental force for much of the advancement throughout the modern world, the globe has ventured on a slippery slope that abandoned the fundamentals of Enlightenment. The left has embraced the same aspects of pre-enlightenment. Instead of the church ruling everything, it is the government that is the almighty power. From ignoring elementary science to censoring speech, the pre-enlightenment era is making a comeback. But will the inherent qualities within the American spirit slay this antiquated thinking?
