"Sachs's outstanding new translation of Plato's Theaetetus is lucid, readable, and faithful to the original. More than that, it is a translation for the thoughtful reader. Through his striking translations of key terms, Sachs compels the reader to think more deeply about Plato's intent. He shows that Plato's return within the dialogue to the same word or to its cognates is no accident but signals a philosophical trope in Plato's thought. The work's introduction avoids presenting a stock summary of the topics covered or a rehearsal of the failed arguments. Instead, it makes the case for regarding the Theaetetus as Plato's 'missing' work on The Philosopher. Through the 'variety of attempts, errors, new beginnings, and false turns that the dialogue presents,' Sachs argues, Socrates provokes his interlocutors and Plato's readers to strive to cross the boundary between mere opinion and the kind of thinking that is philosophy."
