Plato’s Politicus argues for a striking normative claim about the law: the ideal expert ruler will not only change the laws of the city when he thinks it best, but will also contravene them. The Eleatic Stranger’s argument for this conclusion reveals important features of Plato’s views on expertise in general, and political expertise in particular. Laws should not be inviolable for an expert ruler because no craft lays down inviolable rules for its practitioners. There are no inviolable rules of (...) action for experts because crafts are teleological: expert action aims only to produce some good. The expert ruler’s political action recognizes no constraints besides the aim of best promoting the good condition of the whole city. Plato believes that the statesman will do markedly better at promoting this end when unconstrained by even the best laws, and there is evidence that he will harm individual citizens in order to do so.
