This paper argues for an Aristotelian account of good leader as ethical and effective by outlining the ethical motivation and the constraints that moral luck imposes on effectiveness. This account of a good leader, which is grounded on practical wisdom, is assessed against the contemporary leadership debate by addressing the tension between the ethical and the effective and by contrasting the Aristotelian virtuous leader against the dominant contemporary types of leadership. My Aristotelian proposal of a virtuous leader relies on an (...) isomorphic relation between the ethical and political domains by proposing that as virtue is to vices rooted in calculation and desires, so the virtuous leader is to the calculative bureaucrat and the emotionally obsessed tyrant.
