This study investigates the core question of how language relates to reality within the framework of Plato's Cratylus. Rachel Barney, a scholar of ancient philosophy, provides a rigorous examination of the dialogue's linguistic theories and ontological commitments. By integrating textual analysis with an exploration of Plato's broader philosophical methodology, the book argues for a nuanced understanding of how names function as tools for accessing the nature of things. The work situates the Cratylus within the context of Platonic thought, challenging traditional interpretations of the dialogue's stance on naturalism versus conventionalism.

Scholars frequently cite this work as a definitive resource for understanding the complexities of Platonic linguistics and the specific argumentative structure of the Cratylus. Experts highlight the text for its clarity and its ability to reconcile the dialogue's seemingly disparate sections into a coherent philosophical project.
