How could a state be governed, or protected in its foreign relations if every individual remained free to obey or not to obey the law according to his private opinion.
Thomas HobbesAnd therefore, as when there is a controversy in an account, the parties must by their own accord, set up for right Reason, the Reason of some Arbitrator, or Judge, to whose sentence, they will both stand, or their controversy must either come to blows, or be undecided, for want of a right Reason constituted by Nature; so is it also in all debates of what kind soever.
Thomas Hobbes
