The document discusses John Locke's influence on the US Constitution. It explains that Locke introduced the ideas of natural rights and limited government, which greatly impacted the writing of the Constitution. Specifically, Locke's beliefs in life, liberty, and property in his Two Treatises of Government influenced the recognition of basic rights for American citizens. His concept of social contract theory, which argued that citizens have a right to revolt against tyrannical rule, also limited the power of government as established in the Constitution.
