John Locke: Best Quotes and Influential Ideas on Liberty

Who was John Locke?

John Locke (1632–1704) was an English philosopher and physician, widely regarded as one of the most influential Enlightenment thinkers and often called the “Father of Liberalism.”

Locke’s writings on natural rights, government by consent, and the separation of church and state laid the foundation for modern democracy and greatly influenced documents like the U.S. Declaration of Independence and Constitution.

His belief that human beings are born with certain inalienable rights — life, liberty, and property — transformed political thought and continues to shape discussions on freedom and human rights today.
