According to Hobbes, a well-ordered society would be one in which there is a strong central government. In one of his most famous works, Leviathan, Hobbes argues that if there was no strong government to control the people that many societies would be in constant warfare against each other. To prevent this from happening, Hobbes argues that citizens and the government must have a social contract.
