John Locke believed in the social contract which is the acceptance of laws within a society. Basically, if a person were to live in a city, they would have to follow the laws in the city to live there. Thomas Hobbes, one of the founders of the social contract, believed opposite of what Locke did, he believed that all humans were born evil and that laws protect us from our evil state. However, Locke believed that if people wanted to their rights to be safe, they would have to give up some freedom. This would lead to the modern day democracy and republicanism. Locke also believed in Popular Sovereignty, which means that the people create the government, the people have power over the government and the people must have a say in the government. Locke believed that this was the best way to govern.
