What is the Age of Enlightenment?

The Age of Reason, or the Age of Enlightenment, was an intellectual and cultural shift in Europe's seventeenth and eighteenth centuries. It stressed reason, science, rationality and individual rights as opposed to tradition, superstition and absolute power. Philosophers such as John Locke, Voltaire, Rousseau, Montesquieu and Immanuel Kant espoused the notion of liberty, equality, democracy, secularism and free thought. The movement undermined the monarchy and the authority of the church and gave way to revolutions, including the American (1776) and French (1789). Its influence has shaped contemporary democracy, human rights, education, scientific advances, and free-market economics, among many other things that have significantly affected the modern world.

Background of the Age of Enlightenment

The Age of Enlightenment is a movement that emerged in Europe's 17th and 18th centuries as a reaction against centuries of religious manipulation, feudalism and absolutism. It had deep roots in the Renaissance (revival of ancient learning), the Protestant Reformation (religious questioning), the Scientific Revolution (progress of Galileo, Newton, Copernicus) and the Age of exploration (exchange of ideas across the world).

Spreading knowledge and debate in the streets came about due to the advent of the printing press and the middle-class urbanisation. Philosophers started stressing reason, empiricism, and human rights, challenging traditional authority. These developments prefigured the thought of the Enlightenment.

Characteristics of the Age of Enlightenment

The Age of Enlightenment had the following characteristics:

• During the Age of Enlightenment, many European countries experienced intellectual growth. However, each region had its particular focus during this time.
• There were two main ways of thinking during the Enlightenment. The first was the Radical School of thought, which promoted freedom of speech, democracy, and the elimination of authority.
• The second way of thinking was called the Moderate School of thought. This school tried to find a compromise between making changes and keeping the existing religious and political systems in place.
• As time passed, science became increasingly important in Enlightenment discussions and thinking.
• On the question of such things as race, gender and social class, it is the findings of historians that the values of the Enlightenment were not originally intended to apply to all people in the manner by which we now apprehend the notion. The overwhelming majority of thinkers of the Enlightenment thought that rights and freedoms were not hereditary, but they did not necessarily advocate equality for all people. Nevertheless, their theories triggered subsequent movements that championed the rights of people of colour, women and the working classes.

Enlightenment Period: Significant Thinkers & Their Ideas

Numerous thinkers belonged to the Age of Enlightenment. Each has contributed significantly to one or more fields. Among them, the most well-known thinkers of the Enlightenment are mentioned below;

Galileo Galilei (1564-1642)

He was a mathematician and astronomer from Italy. He is well-known for having discovered Jupiter's moons. He advocated the idea that the Earth revolved around the Sun in public. He had to deal with fierce hostility and persecution when he published these beliefs in a book titled Dialogue on the Two Chief Systems of the World, especially from the religious authorities. In 1633, he was put on trial for allegedly contradicting the Bible.

Rene Descartes (1596-1650)

He was a French philosopher known as the "Father of Modern Philosophy." He started as a soldier, but in his free time, he was a philosopher. He made a fresh start in a time of uncertainty by forgoing the conventional scholastic approach. His famous adage is "cogito, ergo sum" (I think, therefore I am). He created his entire philosophy utilising a mathematical method of reasoning, proceeding in this way.

John Locke (1632-1704)

Beginning a new philosophical era, he turned away from reason (Descartes' technique) to sense experience to discover truth in his Essay "Concerning Human Understanding". This marked the beginning of the "Empiricism" movement. He believed that sense experiences are ultimately the source of our ideas. Simple thoughts are combined in the mind to create more complex ones. He was among the first intellectuals to suggest that human beings had inherent rights. This thinking has gradually resulted in our conception of "human rights."

Sir Isaac Newton (1642-1727)

He ranks among the top scientists of all time, most likely. He discovered that white light is a combination of several colours. He developed his Universal Law of Gravitation and created a new area of mathematics known as calculus in less than two years (1665–1677).

Jean-Jacques Rousseau (1712-1778)

He was one of the intellectuals who helped lay the foundation for the French Revolution. He was the author of "The Social Contract", his most significant work. In this, he pointed out that human beings are inherently competitive. Still, despite that, they band together in groups to have a better chance of prevailing in the conflicts and winning. According to Rousseau, the Social Contract was the cornerstone of modern civilisation and society.

National Variation

The era of the Enlightenment, which carried fundamental ideas in Europe, had a different approach in each country. In France, the population had associated enlightenment with anti-government and anti-Church. They were radical in their thought. In Germany, the Enlightenment was extended to the middle classes and was more spiritual and nationalistic, but it did not threaten the government or the established churches.

• The enlightenment was responded to differently by different governments. The French government did not favour enlightenment and attempted to censor what enlightenment thinkers wrote. Some of these thinkers were even imprisoned or exiled. In Britain, the leaders of the Enlightenment in England and Scotland were largely disregarded by the government. The Scottish Enlightenment was a significant part of the establishment of the Enlightenment ideas in the Americas because it centred on liberal Calvinism and the contributions of Isaac Newton.
• In Italy, the Church's power was reduced, leading to a time of great thinking and invention, including new scientific discoveries. The government actively encouraged the arts and sciences in Russia starting in the mid-18th century. This era saw the establishment of the first Russian university, library, theatre, public museum, and independent press.
• During the Age of Enlightenment, special books called universal encyclopedias organised scientific knowledge. These encyclopedias were different from technical dictionaries. The goal of universal encyclopedias was to have a complete book containing all the knowledge humans had. 
• One famous example of a universal encyclopedia is the Encyclopédie, written by Denis Diderot and Jean le Rond d'Alembert. It started being published in 1751, with 35 volumes and more than 71,000 entries. Many of these entries explained the sciences and crafts in great detail. The Encyclopédie was a valuable resource for European intellectuals, providing them with a high-quality overview of human knowledge.

Enlightenment Ideas That Changed the World

The Enlightenment ideas changed the world. These ideas promoted science as a legitimate source of information, fought for human rights against oppression, and countered the church's excesses. It also provided us with representative democracies, republics, modern medicine, and many other things. The 4 most important ideas were:

• Rights: Before the Enlightenment, the belief in equal rights was uncommon. Any deviation from the established hierarchy was considered harmful. 
• Reason/ Rationalism: It was believed that through reason, people could learn the truth, unearth the natural principles governing existence, make the world a better place, and advance society.
• Separation of powers: During the Enlightenment, Europe seriously reevaluated established systems of power.
• Materialism: That rationality developed throughout the 17th and 18th centuries, laying the groundwork for a materialistic perspective on people and the cosmos.

These ideas have changed the course of history.
