A modern and very careful translation of books 3 and 4 of the Tusculan Disputations, with excellent and extensive commentary. The commentary, and the appendices attached, give the book a different look. Rather than just a translation of pseudo-Stoic treatises, it turns more into a comparative account of ancient theories of emotion; the Stoic position being the protagonist.
I cannot stress the commentary's importance well enough. In many instances, Graver fills the gaps left by Cicero when describing Stoic accounts of a given topic. In some instances, some distinctions are more fine-tuned. If a section is unusual within the context (such as Cicero's attack of erotic love, when Stoics approved of it) Graver points this out. In general, the commentary is very thorough and systematic in its approach.
