Cicero was not only a great Roman politician, lawyer and 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.
