The Handbook of Humility is the first scholarly book to bring together authors from psychology as well as other fields to address what we know and don’t know about humility. Authors review the existing research in this burgeoning field that has well over 100 empirical articles and an increasing trajectory of publication. This work should form the basis for research in humility for many years.In this book, chapters address definitions of humility that guide research. Authors also reflect on the practical applications of humility research within the areas they reviewed. The book informs people who study humility scientifically, but it is also an exceptional guide for psychotherapists, philosophers, religious and community leaders, politicians, educated lay people, and those who would like to fuel an informed reflection on how humility might make interactions more civil in relationships, organizations, communities, political processes, and national and international relations.
