This chapter distinguishes two Platonic interests in self-knowledge: the ‘thin’ self-knowledge that a human being is a rational soul using its body as a tool (the Delphic self-knowledge made prominent in the _Phaedrus_, _First Alcibiades_, and elsewhere), and the ‘thick’ self-knowledge of the particular accidental psychological profile of an individual. The two are contrasted in four ways: the thin applies to the entire species, makes no reference to irrational parts, offers no etiology of contingencies, and makes no special use of first-personal knowledge; the thick applies to individuals, incorporates details about the irrational soul, explains the individual through a narrative of the events that shaped them, and is first-personal in making the object of self-knowledge identical with the subject of that self-knowledge. This richer, thicker form of self-knowledge is illustrated with extensive examples from the _Republic_ and _Seventh Letter_.

Greek Philosophers of the Hellenistic Age examines an important but frequently neglected group of philosophers writing after Aristotle between the third and first centuries B.C. The work of a distinguished intellectual historian, this book is based on an erudite reading of a vast number of primary sources: the Greek and Latin writings of the philosophers, and the fragments, paraphrases, and testimonies from their lost works. Kristeller explores the thought of Epicurus; Zenon and Cleanthes, the founder of the Stoic school and his successor; Pyrrhon and Arcesilaus, the founder of Skepticism and the philosopher who introduced it into the Platonic Academy; and Chrysippus, the third head of the Stoic school and its most important representative. Other figures include Carneades and Philo of Larissa, the second and third representatives of Skepticism in the Platonic Academy, respectively; Panaetius, the first leader of Middle Stoicism; and Antiochus of Ascalon, the head of the Academy, who led it back from Skepticism and prepared Middle Platonism, which paved the way for Neoplatonism. Originally presented as a series of lectures before the Scuola Normale Superiore in Pisa, Italy, Greek Philosophers of the Hellenistic Age assesses a group of philosophers who exerted an enormous influence upon pagan and Christian writers of late antiquity - including Cicero and St. Augustine - and on many medieval and early modern philosophers, theologians, and other thinkers.

Tad Brennan explains how to live the Stoic life--and why we might want to. Stoicism has been one of the main currents of thought in Western civilization for two thousand years: Brennan offers a fascinating guide through the ethical ideas of the original Stoic philosophers, and shows how valuable these ideas remain today, both intellectually and in practice. He writes in a lively informal style which will bring Stoicism to life for readers who are new to ancient philosophy. The Stoic Life will also be of great interest to philosophers and classicists seeking a full understanding of the intellectual legacy of the Stoics.

Plato's account of the tripartite soul is a memorable feature of dialogues like the Republic, Phaedrus and Timaeus: it is one of his most famous and influential yet least understood theories. It presents human nature as both essentially multiple and diverse - and yet somehow also one - divided into a fully human 'rational' part, a lion-like 'spirited part' and an 'appetitive' part likened to a many-headed beast. How these parts interact, how exactly each shapes our agency and how they are affected by phenomena like erôs and education is complicated and controversial. The essays in this book investigate how the theory evolves over the whole of Plato's work, including the Republic, Phaedrus and Timaeus, and how it was developed further by important Platonists such as Galen, Plutarch and Plotinus. They will be of interest to a wide audience in philosophy and classics.
