The Midwife of Platonism : Text and Subtext in Plato's Theaetetus

## Abstract Plato’s Theaetetus is thought to have been written after his main middle-period dialogues, in which he expounded his celebrated metaphysical doctrine of Forms. Yet, it is an open-ended Socratic dialogue and investigates the question ‘What is knowledge?’ without positive result, and with an unexpected restraint about invoking the metaphysical theory. Why? This book develops a new solution to the old question. Plato wants to demonstrate the continuity of his mature work with that of his master Socrates and does so by invoking the now famous image, unique to this dialogue, of Socrates as the barren midwife of others’ brainchildren. The message is that Socrates, although not himself a Platonist, was the midwife of Platonism. This is brought out by portraying a Socrates who, rather than Plato’s current spokesman, is a throwback to the semi-historical figure immortalized in the early dialogues. We see this Socrates, in the course of his characteristic dialectical investigations, pointing us to recognizably Platonic solutions, but himself unable to articulate them that way because of his lack of a Platonic metaphysics. In addition to linking Plato’s Socratic past to his Platonic present, the same device also points forward to Plato’s future work in such dialogues as Sophist and Timaeus. Counter Plato's Theaetetus is an acknowledged masterpiece, and among the most influential texts in the history of epistemology. Since antiquity it has been debated whether this dialogue was written by Plato to support his familiar metaphysical doctrines, or represents a self-distancing from these. David Sedley's book offers a via media, founded on a radical separation of the author, Plato, from his main speaker, Socrates. The dialogue, it is argued, is addressed to readers familiar with Plato's mature doctrines, and sets out to show how these doctrines, far from being an abandonment of his Socratic heritage, are its natural outcome. The Socrates portrayed here is the same Socrates as already portrayed in Plato's early dialogues. While not a Platonist, he is exhibited - to put it in terms of an image made famous by this dialogue - as having been Platonism's midwife. In a comprehensive rereading of the text, Sedley tracks the ways in which Socrates is shown unwittingly preparing the ground for Plato's mature doctrines, and reinterprets the dialogue's individual arguments from this perspective. The book is addressed to all readers interested in Plato, and does not require knowledge of Greek

The Theaetetus is among the most brilliant of Plato's dialogues, but is also deeply enigmatic, leaving readers divided over its philosophical intentions. David Sedley proposes and develops a solution, based on a groundbreaking two-level reading. Offering significant reinterpretations of the dialogue's main arguments, The Midwife of Platonism is addressed to all readers interested in Plato, and does not require knowledge of Greek.

Plato's 'Theaetetus', an acknowledged masterpiece, is among the most influential texts in the history of epistemology. Here, the author tracks the way in which Socrates unwittingly prepares the ground for Plato's mature doctrines, and reinterprets the dialogue's arguments from his perspective
