The Rule of Wisdom and the Rule of Law in Plato's Statesman

Recently, the idea of phronesis has assumed great importance among political theorists. This prominence is due to the perception that, contrary to the application of the methods of natural science to politics, phronesis preserves the distinctive character of politics in its refusal to apply inappropriate standards of precision and to find certainty where it does not exist. But precisely because of this, the following question arises: Can we ascertain a nonarbitrary standard of phronesis without denying those characteristics that make it appropriate for the understanding of politics? I address this question by considering the treatment of phronesis (wisdom) found in Plato's Statesman and, in particular, the passage that weighs the relative merits of rule by wisdom and rule by law. In this seminal consideration of phronesis Plato (unlike Aristotle) does not confine his treatment to the practical sphere; even this intensely political passage contains far-reaching reflections on the nature of humanity and the world we inhabit. These explain what we are and what our world is, such that there is a need for this cognitive capacity. As I argue, they express the conditions of phronesis that can provide a guide for its use without negating its essential character.
