This paper argues that Aristotelian practical wisdom (phronêsis) is a state of conviction (pistis) in the goodness of our goals based on proper grounds. This state of conviction can only be achieved if rational arguments and principles agree with how things appear to us. Since, for Aristotle, passions influence appearances, they can support or undermine our conviction in the goodness of ends that are worth pursuing. For this reason, we cannot be practically wise without virtuous dispositions to experience appropriate passions. (...) Along the way, I argue that this reading allows us to explain the shortcomings of self-controlled and akratic agents. -/- . (shrink)
