Incoming: The Enlightenment
Life before the Enlightenment was a world where questioning authority could get you locked up—or killed. It all depended on the mood of the authorities deciding your fate. The thinking back then was that Kings ruled because they claimed God said so, and asking questions could land you in hot water (sometimes literally). Then, around the 16th century, people started asking pesky questions. What if rulers weren’t chosen by God? What if the Earth wasn’t the center of the universe? What if Taylor Swift’s cats were actually AI-powered spies designed to protect her from global threats? Big questions sparked even bigger ideas, and the Age of Enlightenment burst onto the scene.
Between the late 1600s and early 1800s, this intellectual revolution flipped the script. Instead of blindly following tradition, people leaned into reason, science, and freedom to figure things out. Old ideas about power and authority suddenly looked shaky, and new ways of thinking about government, rights, and equality started to take hold.
The Enlightenment wasn’t just a quick brainstorm—it was a full-blown movement. Thinkers challenged everything from government and religion to economics and gender roles. Instead of going along with the status quo, they asked, “Why?” and didn’t settle for easy answers.
Causes of the Enlightenment
If the Enlightenment had a slogan, it would’ve been “Prove it.” People were tired of being told what to believe without evidence. They wanted answers, and curiosity took center stage. It all started with the Scientific Revolution, when Copernicus and Galileo used telescopes to prove the Earth wasn’t the center of the universe—and the church didn’t take it well.
Then came Isaac Newton, who figured out gravity and wrote formulas that explained how the world worked. If science could explain motion and matter, why couldn’t it explain politics and society? Suddenly, old ideas about divine rulers looked about as sturdy as a house of cards.
The Renaissance and Reformation also played their part. The Renaissance brought back art and learning, while the Reformation proved the church wasn’t always right. By the 1600s, questioning authority wasn’t just trendy—it was a cultural revolution.
Add in rising tension between rich monarchs and struggling peasants, and the middle class—merchants, lawyers, and traders—was ready for change. They wanted more say in how things were run, and when kings didn’t listen, the Enlightenment stepped in.

From Absolutism to Enlightenment Ideals
Kings didn’t go down without a fight. Louis XIV’s Versailles wasn’t just a palace—it was a statement. Decked out in gold, mirrors, and fountains, it was built to remind everyone that the king was the center of everything. It was like a royal Instagram post screaming, 'Look how powerful I am!' Louis even called himself the 'Sun King,' claiming that just as the sun was the center of the universe, he was the center of France. But outside the glittering walls of Versailles, people were starting to question whether kings really deserved all that power—or if they’d just been hogging the spotlight.
John Locke was one of the first to call them out. He argued that everyone was born with natural rights—life, liberty, and property—and governments were supposed to protect those rights. If they didn’t? Locke said it was perfectly fine to show them the door.
Not everyone saw people as naturally good, though. Thomas Hobbes thought humans were selfish and chaotic, needing a strong ruler to keep them in line. His book Leviathan argued that peace sometimes meant giving up a little freedom.
Meanwhile, Jean-Jacques Rousseau pushed for democracy. He believed in the general will, the idea that governments should follow what’s best for the people, not just the elites. Baron de Montesquieu added another layer, suggesting a separation of powers so no one branch of government could take over.
And then there was Voltaire, the master of sarcasm who attacked religious intolerance and censorship. He fought for freedom of speech and wasn’t afraid to stir the pot.
For centuries, Europe (and much of the world) were governed by rulers who held absolute authority to make laws, hand out punishments, and interfere in the lives of the people as they saw fit.
The People of the Enlightenment
The Enlightenment wasn’t just about books—it was about conversations. Paris salons and London coffeehouses became hotspots for debates. Philosophers, writers, and artists argued over politics and poetry, fueled by caffeine and curiosity.
Women like Madame Geoffrin opened their homes to host these gatherings, proving that ideas didn’t just belong to men. Merchants and tradespeople joined the discussions too, making salons and coffeehouses feel less like lectures and more like intellectual battlegrounds.
What made these thinkers radical wasn’t just their ideas—it was their belief that the world could be improved. They saw governments, religions, and economies as experiments that could be studied, fixed, or completely rewritten.

The Enlightenment's Impact on Society
The Enlightenment didn’t just shake things up—it turned society upside down and scattered the pieces. Old traditions that had seemed untouchable were suddenly up for debate, and nothing felt off-limits. Religion, government, justice, education, and even art all came under the microscope. It wasn’t just about changing how people thought—it was about reshaping how they lived.
Take religion, for example. For centuries, the church had been the ultimate authority, controlling not only spiritual beliefs but also laws and education. The Enlightenment didn’t destroy religion, but it did force it to loosen its grip. Thinkers like Voltaire pushed for religious tolerance, while others embraced Deism—the idea that God created the world but didn’t micromanage it. Faith became more personal, and people started asking questions the church didn’t always have answers to.
Questions about freedom didn’t stop there. Philosophers began to look at society’s most uncomfortable truths—like slavery. If liberty was a natural right, then how could slavery continue? Writers like Denis Diderot and Condorcet argued that freedom wasn’t just for the privileged—it was a right for everyone. While slavery didn’t end overnight, the Enlightenment set the stage for abolition movements that would come later.
Democracy also got its big break. Before the Enlightenment, most governments were run like exclusive clubs, with kings and queens making the rules and everyone else following them. But Enlightenment thinkers weren’t interested in playing follow-the-leader. John Locke argued that governments should protect the rights of the people, and if they didn’t, the people had the right to replace them. This wasn’t just talk—it lit the spark for revolutions. The American Revolution borrowed Locke’s ideas to write the Declaration of Independence, while the French Revolution demanded liberty and equality—and wasn’t afraid to use a guillotine to make its point.
Even justice systems felt the shift. The days of cruel punishments and public executions started to fade as reformers like Cesare Beccaria argued for fair trials and punishments that actually fit the crime. The idea that someone was innocent until proven guilty became a cornerstone of modern law.
Education became infected with Enlightenment ideals. Schools started focusing less on memorization and more on critical thinking. Enlightenment thinkers believed knowledge wasn’t just for the wealthy—it was for everyone. The push for education eventually led to public schools and universities, giving more people access to learning.
Not everyone benefited equally, though. Women were often left out of the Enlightenment conversation, but that didn’t stop them from speaking up. Mary Wollstonecraft argued that women deserved education and equality in her book A Vindication of the Rights of Woman. Her ideas didn’t create instant change, but they planted seeds that would grow into later movements for women’s rights.
The Enlightenment didn’t just leave behind a few dusty books and fancy speeches—it reshaped everything. From revolutions to rights movements, from schools to courtrooms, its impact is still with us today.
The ideas of human rights and equality of the Enlightenment led to the American and French revolution.
Why It Matters
The Enlightenment didn’t just leave behind a few dusty books and fancy speeches—it sparked ideas that continue to shape the world we live in. It challenged monarchies and inspired revolutions, like the American Revolution, where colonists took up arms to fight for the natural rights John Locke had championed. It set the stage for the French Revolution, which toppled the monarchy and pushed ideas of liberty, equality, and fraternity into the global spotlight. And it planted the seeds for abolition movements, as debates over freedom and equality grew louder, eventually leading to the end of slavery in many parts of the world.
The Enlightenment’s focus on reason and science didn’t stop with the 18th century. It laid the foundation for the Industrial Revolution, where innovations like the steam engine transformed economies and daily life. Modern democracy owes much to Enlightenment ideas about government accountability and individual rights, principles that can be found in constitutions around the world, including the U.S. Constitution and Bill of Rights.
Movements for civil rights and women’s equality also drew heavily from Enlightenment ideals. Mary Wollstonecraft’s push for women’s education planted the seeds for the suffrage movement, while debates about fairness and freedom influenced modern fights for racial and gender equality.
Even today, debates about free speech, religious tolerance, and education reform echo the Enlightenment’s insistence on questioning authority and demanding fairness. The push for scientific discovery and technological advancement reflects the Enlightenment’s belief that progress is not just possible but necessary.
So, the next time you hear someone arguing about human rights, free speech, or fair laws, remember—you’re part of a conversation that started hundreds of years ago. The Enlightenment didn’t just question the old ways—it dared to dream of something better, and that dream is still unfolding.
