  On the other hand, the Revisionist claim that the Theaetetus shows Plato doing more or less completely without the theory of Forms is very plausible. There are no explicit mentions of the Forms at all in the Theaetetus, except possibly (and even this much is disputed) in what many take to be the philosophical backwater of the Digression. The main argument of the dialogue seems to get along without even implicit appeal to the theory of Forms. In the Theaetetus, Revisionism seems to be on its strongest ground of all.
