Abstract and Keywords
The Theaetetus is a principal field of battle for one of the main disputes between Plato's interpreters. This is the dispute between unitarians and revisionists. This article focuses on Plato's ideas on unitarians and revisionists. Plato's greatest work on epistemology, in the Theaetetus, Plato has much to say about the nature of knowledge elsewhere. But only the Theaetetus offers a set-piece discussion of the question “What is knowledge?” This question is raised most vividly for readers of Plato when assessing the central epistemological claim of the Republic: that knowledge is impossible unless one grasps the forms, and also for those who do not recognize the existence of the forms. Plato adopts a complex strategy for examining the nature of knowledge in the Theaetetus: he sometimes has Socrates examine a conception of knowledge purely on its own terms. The two major ideas dealt with in the article are change and form.
