Cicero and Seneca on passions and vices

This article investigates Cicero’s and Seneca’s thoughts about passions and vices (their definitions, origins of emotions and vices, correlation of these concepts, and their correlation with a concept “illness”). Though the Stoics greatly influenced Cicero, and Seneca was a staunch adherent of Stoicism, their thoughts about passions and vices have more distinctions than similarities. The positions of these philosophers on the problems of the variability of vices, their origins and the relationship with the passions, the correlation of the terms “vitia” and “morbi”/”animi morbi” are contrary.
