Abstract
This article introduces the second of two special issues on philosophical approaches to leadership ethics. In this issue, the articles draw on the works of Plato, Niccol Machiavelli, Michel Foucault, and Jurgen Habermas to explore questions in leadership ethics concerning leaders' self-knowledge and self-constitution and their responsibilities to their followers. The articles in this issue demonstrate the potential of philosophy to deepen our understanding of leadership and ethics.
