  Revisionists are committed by their overall stance to a number of more particular views. They are more or less bound to say that the late Plato takes the Parmenides’ critique of the theory of Forms to be cogent, or at least impressive; that the Sophist’s theory of “the five greatest kinds” (Sophist 254b–258e) is not a development of the theory of Forms; and that the Timaeus was written before the Parmenides, because of the Timaeus’ apparent defence of theses from the theory of Forms. Their line on the Theaetetus will be that its argument does not support the theory of Forms; that the Theaetetus is interesting precisely because it shows us how good at epistemology Plato is once he frees himself from his obsession with the Forms.
