John Locke

John Locke (1632-1704) was an English philosopher and the 'Father of Liberalism,' whose ideas shaped the Enlightenment and modern democratic governance. In *An Essay Concerning Human Understanding*, he argued that the mind is a *tabula rasa* (blank slate) at birth, with all knowledge deriving from experience, founding the school of British Empiricism. Politically, his *Two Treatises of Government* challenged the divine right of kings, asserting that all individuals possess natural rights to life, liberty, and property. He proposed that government is a social contract based on the consent of the governed, with a right to revolution if that trust is betrayed. His *A Letter Concerning Toleration* further advocated for the separation of church and state. Locke’s foundational principles directly informed the American Declaration of Independence and current constitutional traditions worldwide, prioritizing individual liberty and the rule of law.
