But, though there had never been any time wherein particular men were in acondition of war one against another, yet in all times kings and persons ofsovereign authority, because of their independency, are in continual jealousiesand in the state and posture of gladiators, having their weapons pointing, andtheir eyes fixed on one another, that is, their forts, garrisons, and guns, upon thefrontiers of their kingdoms, and continual spies upon their neighbours: which isa posture of war.
I interpreted this as Hobbes saying that there was never a time where individuals would wage war on each other. They only went to war because they were forced to by authority figures. For the most part, they only went to war due to jealousy.
