This chapter examines St Thomas Aquinas' political ideas. Aquinas combined Aristotelian ideas with Christian concepts, distinguishing between the natural and supernatural orders, and attributing inherent validity to the natural order, including political life. His theory of law linked, through reason, the eternal law of God, natural law, human positive law, and divine law. According to Aquinas, government's justification was its purpose — securing the common good. He favoured limited monarchy in a mixed constitution. The chapter first provides a short biography of Aquinas before discussing his views on natural and supernatural orders, government, tyranny, and temporal and spiritual power. It concludes with an assessment of Aquinas' contribution to political thought in the area of just war theory.
This chapter examines Hugo Grotius' key political ideas. Grotius, one of the most prolific and erudite writers of the seventeenth century, sought to formulate a set of universal rights and duties that would secure peace by constraining states in their internal and external relations. Drawing on a wide range of philosophical and literary sources, including Roman law, ancient classics, theology, and poetry, Grotius rehabilitated the natural law in an attempt to achieve harmony in an increasingly splintered political environment. After providing a short biography of Grotius, the chapter analyses his views on natural law, natural rights, property rights, sociability, self-preservation, and social contracts. It also discusses Grotius' arguments regarding international order in the context of just war theory and punishment and concludes with an assessment of Grotius' legacy in the area of political thought.

This chapter examines Cicero's social and political theory, which rests upon his conception of human nature, namely that human beings are capable of speech and reason. It first provides a short biography of Cicero before discussing his discursive approach to republican rule based on the claim that human nature can only be fully realized through articulate and wise speech. For Cicero, social order requires wise leaders who direct citizens toward the proper goals of cooperation and mutual advantage and who thus seek peace rather than war. The chapter proceeds by analysing Cicero's argument that political institutions must be built upon natural law and virtue, especially justice, along with his notion of patriotic citizenship and his views on war and peace; statesmanship, courage, and otium; the origins of political inequality; and republican government.
