Platonism and Dialogue

With the banishment of Plato's Political writings to the Political Science Department, Platonism is typically presented in contemporary American academic Philosophy as fundamentally Epistemology, the central thesis of which being that Knowledge is Justified True Belief.  On that basis, Dialogue is an inessential style of presentation.  However, with the Republic, etc. included, the arc of Platonism is from the execution of the wisest man, to the Philosopher-King.  In that context, Epistemology functions to clarify the concept of Wisdom, and Dialogue is a continuation of the Apology, except with the wisest man now the prosecutor rather than the defendant.  And, even as himself an academic, Political Virtue remains for Plato a, if not the, focus of his concept of Philosophy, as is also the case with his star pupil.
