The present volume offers a collection of papers on one of Plato’s most intriguing dialogues. Although not a running commentary, the book covers the majority of difficult questions raised by the dialogue in which the subjects of language and ontology are tied closely together. It shows why Plato’s Cratylus has been highly regarded among readers interested in ancient philosophy and those concerned with modern semantics and theory of language. This collection also presents original views on the position of the dialogue in the whole Plato’s œuvre and in the context of Plato’s contemporaries and successors.
