The Second Treatise is notable for a number of themes which Locke develops therein. It begins with a depiction of the state of nature, wherein individuals are under no obligation to obey one another but are each themselves judge of what the law of nature requires. It also covers conquest and slavery, property, representative government, and the right of revolution. A classic of political theory. The Second Treatise outlines a theory of civil society. Locke begins by describing the state of nature, a picture much more stable than Thomas Hobbes' state of "war of every man against every man," and argues that all men are created equal in the state of nature by God. From this, he goes on to explain the hypothetical rise of property and civilization, in the process explaining that the only legitimate governments are those which have the consent of the people. Thus, any government that rules without the consent of the people can, in theory, be overthrown.
