Thomas Hobbes and John Locke are considered the first modern political philosophers. Both philosophers used their personal opinions as a means to develop their theories on human nature, the origin of the state, the nature of government, and the right to revolution. The two philosophers contributed in many fields: politics, governance and the life of individuals. Because of their different approaches to the same points, they differed on views of human nature, the right to revolution, and the nature of governments. Their views on human nature influenced their philosophies on government theory. Because of their different perspectives, Hobbes and Locke looked at the theory of nature differently. Thomas Hobbes believed that the people of the State have the complete and absolute right to revolt for fundamental rights when these are violated (Hobbes, 36). Furthermore, he considered people to be rational, free, and well-informed. Since people always try to get what is beneficial to them, Hobbes observed that the desire and aspiration to acquire things that were similar in society is the reason for competition. However, this conflicted with the king's divine right to rule. It presented a dilemma: How can simple people of the state overthrow the king without it being considered treason? Hobbes' theory was a radical concept for its time. He stated, “The right of nature…is the liberty every man has to use his own power, as he will, to preserve his own nature” (Hobbes 36). On the contrary, the law of nature indicates “by which man is prohibited from doing that which destroys his life or takes away the means of preserving it; and omit what he thinks it can best be preserved with” (Hobbes, 36-37). Starting in the middle of the document as having absolute power over the natural rights of people (Locke, 57). Therefore, because of natural law and the separation of powers, government has limits. Locke had a more positive view of human nature and believed that the social contract had a chance of working. However, he stated that while people have the potential to live in harmony with the government, if the government does not honor the contract, then the people may rebel (Locke, 60). In summary, although both John Locke and Thomas Hobbes are very influential, they had conflicting opinions. The theories of these philosophers are the foundation of modern democracy. Both are recognized for their important role in defining and influencing human rights in modern politics. John Locke and Thomas Hobbes are some of the most influential minds in political science in the modern age.
