The state of nature, social contract theory by Locke starts from the concept of man in a primitive state without political authority or formal checks on the behaviour of individuals. They considered that such a stateless autonomous condition could not prevail if man was to move beyond a primitive existence. This could only be achieved if man could be guided by natural law that would lead them to a developed social and political life. The major purpose of this project revolves in stating and analyzing the theory of the state of nature, social contract as seen and conceived by John Locke. John Locke’s state of nature is a state of natural law. The natural being “the non-aggression principle.” The state of nature is governed by a law that creates obligations for everyone. And reason, which is that law, teaches anyone who takes the trouble to consult it, that because we are all equal and independent, no one ought to harm anyone else in his life, health, liberty, or possessions. There are lots of information that can be derived from the study. In Locke’s state of nature, social contract, described the state of nature and man’s progression into ‘civil’ society. Locke agrees that before men came to govern themselves, they all existed in a state of nature. But, however, the reasons which force man into such a society differ from one author to the other. This, in turn, leads them to have a contrasting view point on the powers and duties of the sovereign as well the state.
