In this article, we discuss Greek and Roman conceptions of liberty. The supposedly ‘neo-Roman’ view of liberty as non-domination is really derived from negative Greek models, we argue, while Roman authors devised an alternative understanding of liberty that rested on the equality of legal rights. In this ‘paleo-Roman’ model, as long as the law was the same for all, you were free; whether or not you participated in making the law was not a constitutive feature of liberty. In essence, this (...) Roman theory was a theory of freedom as the rule of law and the guarantee of equal rights, especially due process rights. For this Roman concept of ‘legal liberty,’ as we call it, political participation was neither necessary nor sufficient. Theorized by Cicero and historicized by Livy, the Roman understanding of freedom flourished in early-modern times, proving important to paradigmatic republican authors such as Machiavelli and Rousseau as well as to Hobbes, whose work we discuss as a helpful point of comparison.
