Before reading

What you will learn

Understand the natural-law argument, follow its translation into civic statutes, and assess the relation between rational ideal and Roman institutions.

Short summary

Cicero seeks the foundation of law in a reason common to human nature before examining Roman religious institutions and magistracies. The dialogue thereby connects natural law, constitution, and republican reform.

Long summary

The discussion begins from justice and rejects its reduction to convention or the interest of the stronger. It then formulates model laws for religion and political organization in the solemn language of Roman legislation.

The move from universal principle to civic rule creates the central difficulty. Cicero presents Roman institutions as a possible expression of reason while selecting and correcting them according to his conservative project.
