This chapter examines Hobbes’s conception of civil peace, paying particular attention to his ideas about political authority, justice, and the rule of law. Hobbes wants to make rulers immune from accusations of injustice and claims that all laws are, by definition, just. However, his political theory also reveals a positive vision of lasting peace in a well-governed commonwealth. This chapter shows that sovereigns must not only protect individuals from violence, but also should prevent social conflict and settle disputes between subjects. In Hobbes’s view, this requires that rulers institute and guarantee individual rights, govern in an equitable manner, and ensure fairness in the administration of justice.
