John Locke was an Enlightenment philosopher from England. He is considered one of the most influential Enlightenment thinkers and is often referred to as the 'Father of Liberalism'. His works on political philosophy, particularly his Second Treatise of Government, had a profound impact on the development of modern political thought. He also wrote extensively on religious toleration, education, and the nature of knowledge. Locke's ideas were highly influential in the American Revolution and the French Revolution.
