Thomas Hobbes and John Locke were two English philosophers, considered to be the founders of modern political philosophy. Both of them justified and articulated the reason for the role of state, but their conclusions certainly differ from each other. Hobbes and Locke start from the opposite end of the spectrum in assumptions about human nature. Hobbes' teaching on the state implies the ideal of absolute rule in which the function of the state is the security of the individual, that he could not achieve in the natural state. The state is created by concluding a mutual agreement among its citizens, which transfer part of the natural right to the sovereign. With the establishment of the state, a subjects renounce the right to change the form of government and rebellion. What differs most from Hobbes' theory is Locke's idea of the sovereign. Hobbes claims that the sovereing always acts in a way that is consistent with the public good while Locke is skeptical of the sovereign authority. For Locke, the consent of the people is essential to the creation of a community or government. Hobbes allows the sovereign to use any means to ensure the stability of the community. Locke, on the other hand, does not allow the sovereign absolute power. If the sovereign breaks the law and starts acting out of private interests, than the people reserve the right to reject the sovereign and establish a new legislative power. Locke points out that the sovereign is only a man, who is subject to the same mistakes as all other people. Hobbes and Locke have two completely different views on the idea of revolution. Hobbes believes that the people should not rebel against the sovereign. Because the dissolution of the community immediately means a return to the natural state in which life is cruel, and its ultimate goal is to never repeat it. For this reason, people need authority to ensure the establishment of peace and security. Locke thinks there needs to be some strong reason for a drastic change in the form of government. He claims that the real rebel is actually the sovereign who violates the social contract. Thomas Hobbes and John Locke have the ultimate goal of preserving the peace and security of people, each through their own conception of the human species, the creation of the state and the sovereign.
