The state of nature, in moral and political philosophy, religion, social contract theories and international law, is the hypothetical life of people before societies came into existence. Philosophers of the state of nature theory deduce that there must have been a time before organized societies existed, and this presumption thus raises questions such as: "What was life like before civil society?"; "How did government first emerge from such a starting position?," and; "What are the hypothetical reasons for entering a state of society by establishing a nation-state?".
