Overview: The philosopher John Locke believes that individuals have certain rights so fundamental that no government can ever take them away. These rights—to life, liberty and property—were given to us as human beings in the the state of nature, a time before government and laws were created. According to Locke, our natural rights are governed by the law of nature, known by reason, which says that we can neither give them up nor take them away from anyone else. Sandel wraps up the lecture by raising a question: what happens to our natural rights once we enter society and consent to a system of laws?
