Practical wisdom (phronesis) is a key term in Aristotle's ethics, especially when it comes to explain and to understand the right way to act. In this article, I aim at the character of practical wisdom (phronesis) in Aristotle's Nicomachean Ethics. I try to point out that practical wisdom consists of few subordinate abilities.
