The aim of is to establish and explore a new ‘cultivation of the self’ strand within contemporary moral philosophy. Although the revival of virtue ethics has helped reintroduce the eudaimonic tradition into mainstream philosophical debates, it has by and large been a revival of Aristotelian ethics combined with a modern preoccupation with standards for the moral rightness of actions. The essays comprising this volume offer a fresh approach to the eudaimonic tradition: instead of conditions for rightness of actions, it focuses on conceptions of human life that are best for the one living it. The first section of essays looks at the Hellenistic schools and the way they influenced modern thinkers like Spinoza, Kant, Nietzsche, Hadot, and Foucault in their thinking about self-cultivation. The second section offers contemporary perspectives on ethical self-cultivation by drawing on work in moral psychology, epistemology of self-knowledge, philosophy of mind, and meta-ethics.
