John Locke's philosophical foundation for democracy revolves around the concepts of natural rights and the social contract. He argued that individuals are born with inherent rights to life, liberty, and property, which governments are obligated to protect. If a government fails to do so, Locke maintained that the people have the right to revolt. His writings influenced Enlightenment thought and informed democratic principles, asserting that governments derive their legitimacy from the consent of the governed. Locke’s ideas laid the groundwork for modern liberal democracy, emphasizing individual rights and the importance of governmental accountability to its citizens.
