In ethics, political philosophy, social contract theory, religion, and international law, the term state of nature describes the hypothetical way of life that existed before humans organised themselves into societies or civilisations.[1] Philosophers of the state of nature theory propose that there was a historical period before societies existed, and seek answers to the questions: "What was life like before civil society?", "How did government emerge from such a primitive start?", and "What are the hypothetical reasons for entering a state of society by establishing a nation-state?".
In some versions of social contract theory, there are freedoms, but no rights in the state of nature; and, by way of the social contract, people create societal rights and obligations. In other versions of social contract theory, society imposes restrictions (law, custom, tradition, etc.) that limit the natural rights of a person. Societies existing before the political state are investigated and studied as Mesolithic history, as archaeology, and as cultural anthropology, as social anthropology, and as ethnology to determine the particulars of the indigenous society's social structures and power structures.
