The Enlightenment: Key Ideas, Thinkers, and Impact

The Enlightenment: An Age of Reason

The Enlightenment was an 18th-century intellectual and cultural movement that questioned the foundations of the Ancien Régime. Enlightenment thinkers championed reason as the primary means of understanding the world. They rejected anything that could not withstand rational scrutiny as deception and falsehood. Tolerance was considered fundamental to human relations, and religious intolerance was strongly criticized. They believed that education and progress would improve living conditions. The era was dubbed “The Century of Lights” because 18th-century philosophers believed that the light of reason would dispel the shadows of ignorance after centuries of obscurantism.

Key Ideas of the Enlightenment

Key Ideas of Enlightenment Intellectual Movement

  • Reason: Understood as human rationality capable of illuminating darkness and societal errors.
  • Progress: Viewed as the advancement of knowledge, enabling civilization to control nature and generate well-being and wealth.
  • Happiness: Considered an individual right and a societal goal that leaders were obligated to facilitate.

The Ancien Régime

The Ancien Régime was the term used by critics of the old order, particularly during the French Revolution, to disparagingly describe the political and social structure of France. It represented the old, antiquated, and outdated system that they sought to replace with a new and improved one. Throughout the 19th century, the Ancien Régime was gradually superseded by capitalist class society.

On July 4th, 1776, the Declaration of Independence, written by Thomas Jefferson, was proclaimed.

The war concluded in 1783, and George Washington was declared the first president.

In 1787, the Constitution of the United States was finalized.

The United States won the War of Independence against Great Britain and declared itself a federal republic, granting significant power to the president while allowing each federal state considerable autonomy in areas such as justice, education, and security.
