Philosophy: Ancient: Theaetetus

Desjardins conclusion, that the Theaetetus really does point to a particular theory of knowledge, certainly will be controversial, since for many people the idea that the Theaetetus fails to define knowledge is the cornerstone of their interpretation of Plato s later philosophical thought. But whatever one thinks about the conclusion, it must be agreed that the manner in which it is defended is intrinsically important. Desjardins starts from the unassailable premise that the dialogues are internally unified, and that everything in the dialogues is there for a reason. Her method, then, is to show how some of the features of the dialogue that are usually not taken very seriously actually are very important. Of course, she is not the only scholar taking this sort of tack, but what she makes of the various elements of the Theaetetus is a most impressive construction."
