  The fault-line between Unitarians and Revisionists is the deepest fissure separating interpreters of the Theaetetus. It is not the only distinction among overall interpretations of the dialogue. It has also been suggested, both in the ancient and the modern eras, that the Theaetetus is a sceptical work; that the Theaetetus is a genuinely aporetic work; and that the Theaetetus is a disjointed work. However, there is no space to review these possibilities here. It is time to look more closely at the detail of the arguments that Plato gives in the distinct sections of the dialogue.
