John Locke stands at the heart of the age of enlightenment, a philosopher whose ideas about knowledge, rights, and government became foundations of the modern democratic world.
Empiricism and the mind
In his Essay Concerning Human Understanding, Locke rejected the idea of innate ideas, arguing instead that the mind begins as a blank slate and that all knowledge derives from experience. This founding statement of empiricism shaped the philosophical tradition carried forward by David Hume and others.
Natural rights and government
In his Two Treatises of Government, Locke argued that all people possess natural rights to life, liberty, and property, and that legitimate government rests on the consent of the governed. Where Thomas Hobbes had used the social contract to justify absolute power, Locke argued for limited government and the right of people to resist tyranny.

Locke’s political philosophy inspired the American and French revolutions and shaped the generation of founders that included Benjamin Franklin. As the father of liberalism, his influence endures in constitutions and declarations of rights across the world.
