Techne and Political Philosophy

According to Plato, what qualifies the Philosopher to rule is Knowledge of the Idea of the Good.  Now, such Knowledge is Contemplation, but though he suggests that via the influence of that Idea, a ruler can harmonize the Polis, he does not explain how they can accomplish that.  In other words, Plato does not examine the Techne of ruling, and nor does Aristotle.  And nor does Bacon, even as he elevates Techne over Contemplate.  Rather, perhaps the only major work of Political Philosophy in which ruling is treated as a skill is The Prince.  So, while the break of the latter from Ancient Political Philosophy is generally considered to be its promotion of less than noble conduct in a ruler, the more fundamental innovation may be, a century before Bacon, the implicit elevation of Techne over Contemplation as the Knowledge that is essential to successful ruling.
