The classification levels become more specific towards the bottom. Many organisms belong to the same kingdom, fewer belong to the same phylum, and so on, with species being the most specific classification. A species is one group of genetically distinct, interbreeding organisms.
For Locke, in the state of nature all men are free to order their actions, and dispose of their possessions and persons, as they think fit, within the bounds of the law of nature. (2nd Tr., Â§4). The state of Nature has a law of Nature to govern it, and that law is reason. Locke believes that reason teaches that no one ought to harm another in his life, liberty, and or property (2nd Tr., Â§6) ; and that transgressions of this may be punished.
For him, it was not just an agreement among the people, but between them and the sovereign (preferably a king). According to Locke, the natural rights of individuals limited the power of the king. The king did not hold absolute power, as Hobbes had said, but acted only to enforce and protect the natural rights of the people. If a sovereign violated these rights, the social contract was broken, and the people had the right to revolt and establish a new government. Less than 100 years after Locke wrote his Two Treatises of Government, Thomas Jefferson used his theory in writing the Declaration of Independence.
