The Sophist sets out to explain what the sophist does by defining his art. But the sophist has no art. Plato lays out a challenging puzzle in metaphysics, the nature of philosophy, and the imitation of philosophy that is unraveled in this new and unconventional interpretation.

Here is a new translation of this important late Platonic dialogue, with a comprehensive commentary that reverses the dominant trends in the scholarship of the last fifty years. The Sophist is shown to be not a dry exposition of doctrine, but a rich exercise in dialectic, which reveals both the Eleatic roots of Platonic metaphysics and Plato's criticism of unrevised Eleaticism as a theoretical underpinning for sophistry.

The Sophist is presented now not as an artefact of the intellectual past or precursor of late 20th century philosophical theories, but as living philosophy. In a new translation and interpretation, this late dialogue is shown to be a defense of and not a departure from Plato's metaphysics.

The book is intended to provide a complete interpretation of Plato's Sophist as a whole. Central to the methodology adopted is the assumption that all elements of the dialogue to be understood must be understood in the context of the dialogue as a whole and in its relation to other works in the Platonic corpus.
