Hobbes and Rousseau both used the concept of human nature to develop their theory. Hobbes says man is naturally competitive, and Rousseau says man becomes competitive after a society is formed.
Even though their theories differ in the nature of humans, their theories both seem to say that people need to be controlled, when they are different in their methods.
If human nature is what Hobbes says it is, does that necessarily mean we cannot achieve peace without a commonwealth? Some people value one’s own survival, while some people value the survival of a group more. However, the purpose of a society is not only for an individual to survive, but to survive as an individual.
