John Locke's political text that profoundly influenced Enlightenment thinking is "Two Treatises of Government," published in 1689. In this work, Locke articulated ideas about the nature of government, the social contract, and the rights of individuals. He argued that governments are formed by the consent of the governed and must protect life, liberty, and property. This text heavily influenced political philosophy and laid the groundwork for modern democratic thought, including ideas that inspired the American and French revolutions. Locke's concepts of natural rights and the separation of powers remain foundational in contemporary discussions of government and individual rights.
