Some philosophers argue that false speech and false belief are impossible. In the Sophist, Plato addresses this 'falsehood paradox', which purports to prove that one can neither say r believe falsehoods (because to say or believe a falsehood is to say or believe something that is t, and is therefore t there to be said or believed). In this book Paolo Crivelli closely examines the whole dialogue and shows how Plato's brilliant solution to the paradox is radically different from those put forward by modern philosophers. He surveys and critically discusses the vast range of literature which has developed around the Sophist over the past fifty years, and provides original solutions to several problems that are so far unsolved. His book will be important for all who are interested in the Sophist and in ancient ontology and philosophy of language more generally.
Paolo Crivelli is Associate Professor of Ancient Philosophy at the University of Geneva, Switzerland. He is the author of Aristotle on Truth (Cambridge University Press, 2004).
