An intellectual movement, not a single event
Unlike a war or a single political revolution, the Enlightenment was a broad, decades-long intellectual movement spanning roughly the late 17th through the 18th century, spread through philosophical writings, salons, coffeehouses, and the increasingly widespread printing press, rather than originating from any single defining moment.
Frequently Asked Questions
Did all Enlightenment thinkers agree with each other?
No β while they broadly shared a commitment to reason over blind tradition, Enlightenment philosophers frequently disagreed sharply on specific political and philosophical questions, including the ideal form of government and the exact nature of human rights.
Why is the Enlightenment considered so influential on modern government?
Concepts like natural rights, the social contract, and the separation of powers, all developed or popularized during the Enlightenment, directly shaped founding documents like the U.S. Constitution and continue to form the philosophical basis of many democratic systems worldwide today.
The Social Contract
The idea, developed by thinkers including Locke, Rousseau, and Hobbes, that legitimate government authority derives from an implicit agreement among the people being governed, rather than from divine right or inherited power alone.
