Abstract: The theoretical analysis of vices and emotions has a practical goal: namely, their detection and removal. This chapter offers a rapid survey of Philodemus' methods of treatment and determines the place that they occupy in the therapeutics of the Hellenistic era. There are at least two ways of doing such a survey: vertical and horizontal. A vertical treatment could be a matter of going through the treatises one by one and studying the methods employed in each treatise concerning a single trait or a cluster of related traits. Horizontal approaches are broader and more conceptual. They cut across long time periods, geographical areas, schools, and objects of treatment.

Keywords: Philodemus, vertical treatment, horizontal treatment, therapeutics, Hellenistic era,
