Rich in drama and humour, they include the controversial Ion, a debate on poetic inspiration; Laches, in which Socrates seeks to define bravery; and Euthydemus, which considers the relationship between philosophy and politics. Together, these dialogues provide a definitive portrait of the real Socrates and raise issues still keenly debated by philosophers, forming an incisive overview of Plato's philosophy.

Ennead VI.4-5, originally written as a single treatise, contains Plotinus' most general and sustained exposition of the relationship between the intelligible and the sensible realms, addressing and coalescing two central issues in Platonism: the nature of the soul-body relationship and the nature of participation. Its main question is, How can soul animate bodies without sharing their extension? The treatise seems to have had considerable impact: it is much reflected in Porphyry's important work, Sententiae, and the doctrine of reception according to the capacity of the recipient, for which this treatise is the main source, resonated in medieval thinkers.

Scholars of Plato are divided between those who emphasize the literature of the dialogues and those who emphasize the argument of the dialogues, and between those who see a development in the thought of the dialogues and those who do not. In this important book Russell Dancy focuses on the arguments and defends a developmental picture. He explains the Theory of Forms of the Phaedo and Symposium as an outgrowth of the quest for definitions canvassed in the Socratic dialogues, by constructing a Theory of Definition for the Socratic dialogues based on the refutations of definitions in those dialogues, and showing how that theory is mirrored in the Theory of Forms. His discussion, notable for both its clarity and its meticulous scholarship, ranges in detail over a number of Plato's early and middle dialogues, and will be of interest to readers in Plato studies and in ancient philosophy more generally.
