Enlightenment

noun (proper noun when referring to the 18th-century movement; common noun otherwise)
/ɪnˈlaɪt(ə)nmənt/
The Enlightenment (also 'Age of Reason') was an 18th-century European intellectual movement centred in France, Britain, Scotland, and Germany that championed reason, science, individual rights, secularism, and progress over superstition, tradition, and ecclesiastical authority. Key figures include Voltaire, Rousseau, Locke, Montesquieu, Kant, and Hume. Its ideas directly informed the American (1776) and French Revolutions (1789), the principles of constitutionalism, and the colonial critique deployed by Indian nationalists. In UPSC GS1 (World History) it is a foundational topic for understanding modern political thought.

✍️ Usage in a UPSC answer

The Enlightenment's doctrine of natural rights, transmitted through Rousseau's Social Contract and Locke's Second Treatise, provided Indian liberal nationalists like Gopal Krishna Gokhale and the early Congress with a universalist vocabulary of popular sovereignty that was simultaneously anti-colonial and constitutionalist.

🔡 Root

Old English inlīhtan (to illuminate, to make clear) → enlighten (verb) + -ment (noun suffix of process/result)

📜 Etymology

From the Old English verbal root inlīhtan (to light up, illuminate), compounded with the Latin-derived suffix -ment. The philosophical usage as a historical period name translates German Aufklärung (clearing up, illumination) and French Lumières (lights), terms applied retrospectively by 19th-century historians to the 18th-century rationalist movement. Kant's 1784 essay 'What is Enlightenment?' — defining it as humanity's emergence from self-incurred tutelage — remains the canonical self-definition.

🧠 Memory Hook

EN-LIGHTEN-ment: literally 'to light up' the darkness of superstition with the candle of REASON. Picture the philosophes lighting candles in a dark medieval church — each candle = one idea (rights, liberty, progress).
