I want to know the answer to the following question:
In which of John Locke's works are natural rights most famously defined and discussed?
All the background I'm provided with is that "Both Rousseau and Locke's social contract theories rest on the presupposition of natural rights, which are not a result of law or custom, but are things that all men have in pre-political societies, and are therefore universal and inalienable.". Is that enough to answer the question?
