This volume features new findings by nine interdisciplinary teams of researchers on the topics of self, motivation, and virtue. Nine chapters bringing together scholars from the fields of philosophy, psychology, neuroscience, and sociology advance our substantive understanding of these important topics, and showcase a variety of research methods of interdisciplinary interest. Essays on Buddhism and the self in the context of romantic relationships, the development of personal projects and virtue, the notion of self-distancing and its moral impact, virtues as self-integrated traits, humility and the self in loving encounter, the importance of nation and faith in motivating virtue in western and non-western countries, roles for the self and virtue in eudaimonic growth, overcoming spiritual violence and sacramental shame in Christian communities, and an investigation into the moral self highlight the range and diversity of topics explored in this volume. The concept of deep integration also characterizes this work: each member of the interdisciplinary teams was fully and equally invested in their project from inception to completion. This approach invites teams to examine their disciplinary assumptions, rethink familiar concepts, and adjust methodologies in order to view their topics with fresh eyes. The result is not only new findings of substantive and methodological interest, but also an interesting glimpse into the thinking of the researchers as they sought interdisciplinary common ground in their research. Self, Motivation, and Virtue will be of interest to scholars in philosophy, moral psychology, neuroscience, and sociology who are working on these topics.
