Teachers exemplify three important Aristotelian virtues: Episteme, Techne, and Phronesis. Episteme is the knowledge of universal truth (science) and Techne is the ability to make things. But what Aristotle regarded as the highest intellectual virtue – and what captures the teaching profession best – was what he called Phronesis: practical wisdom. We need wisdom to make judgements about what is desirable or good again and again. In essence: we need more practical knowledge in education.
