Plato’s Euthyphro is important because it gives an excellent example of Socratic dialogue in operation and of the connection of that dialectic with Plato’s earlier theory of Forms. Professor Allen’s edition of the dialogue provides a translation with interspersed commentary, aimed both at helping the reader who does not have Greek and also elucidating the discussion of the earlier Theory of Forms which follows. The author argues that there is a theory of Forms in the Euthyphro and in other early Platonic dialogues and that this theory is the foundation of Socratic dialogue. However, he maintains that the theory in the early dialogues is a realist theory of universals and this theory is not to be identified with the theory of Forms found in the Phaedo, Republic, and other middle dialogues, since it differs on the issues of ontological status.

Plato's 'Euthyphro' is important because it gives an excellent example of Socratic dialogue in operation and of the connection of that dialectic with Plato's earlier 'Theory of Forms'. This edition of the dialogue provides a translation with interspersed commentary.

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.
