What contribution did Thomas Hobbs make to the enlightenment

He wrote the book Leviathan which established the idea of the social contract. the social contract states that individuals give up some rights in order to be protected by the government. This form of thinking is very popular in western politics and can be shown through the collection of taxes. This is also very common in American government as seen by the fact that in the Declaration of independence the founding fathers said 'governments are instituted among men deriving their just powers from the governed' which means that any power the government has was consented to, in part, by those who are governed.
