Bellum omnia omnes

"Bellum omnia omnes" is Latin for The war of all against all. It is the description that Thomas Hobbes gives to human existence in the state-of-nature thought experiment[?] that he conducts in Leviathan. This thought experiment places people in a pre-social condition, and theorizes what would happen in such a condition. The outcome according to Hobbes is that people choose to enter a social contract, giving up some of their liberties in order to enjoy their property. This thought experiment is a test for the legitimation[?] of a state in fulfilling its role as "sovereign", and for comparing different types of states on that basis.
