Cicero was not only a great Roman politician, lawyer and orator: he also dealt extensively with philosophy, which he believed constituted the surest foundation for his commitment to civic affairs. Not limiting himself to the translation of previous philosophical thought, he critically addressed central theoretical questions, and thereby made a lasting impact on Roman intellectual life. This book offers a modern guide to interpretations of Cicero's philosophical studies, one that ranges across his numerous philosophical works. Addressed to students and scholars of ancient philosophy, and to interested readers in the humanities more generally, the volume aims to break down the boundaries between the philosophical, literary and linguistic dimensions of Cicero's highly influential oeuvre. Stefano Maso is a full professor in Ancient Philosophy at the University of Ca' Foscari - Venice. Among his books are: Grasp and Dissent: Cicero and Epicurean Philosophy (Brepols 2015); Epicurus on Eidola: Peri Phuseos Book II. Update, Proposals, and Discussions (ed. with F. Masi, Hakkert 2015). He is co-editor of "Lexis. Poetica, retorica e comunicazione nella tradizione classica".
