This book arose initially from my fascination with certain of the Platonic Socrates' interlocutors, and in particular with Callicles and Alcibiades. Why was Plato so ready to give room to the views of such unSocratic and charismatic opponents? The answer, I believed, had largely to do with his abiding interest in different conceptions of manliness and courage (andreia), and hence also with different conditions of the spirited element of the Republic's tripartite psuchē (the thumos), with which andreia is especially connected. At this juncture I came across Allan Bloom's interpretative essay on the Republic, in which he highlights the central role played by Achilles in Books 2 and 3, and it became evident that Plato's concern with Achilles throughout the early and middle dialogues was also part of this interest in notions of andreia. In short, it seemed to me that there was a book to be written on andreia and thumos in early and middle Plato, focusing not only on the theoretical discussions of the Laches and Protagoras, but also on these three characters (who were quickly joined by Thrasymachus).

Such a study necessarily touches on many overlapping aspects of Plato's thought. The introduction of Achilles inevitably raises the issue of Plato's complex attitude to Homer, and his ambivalent deployment of other Homeric heroes, most notably Odysseus. Such topics in their turn prompt questions concerning role models and education in general, and relations between individual and community.
