The Kindness of Strangers: How a Selfish Ape Invented a New Moral Code 

How did humans, a species of self-centered apes, come to care about others? Since Darwin, scientists have tried to answer this question using evolutionary theory. In The Kindness of Strangers, psychologist Michael E. McCullough shows why they have failed and offers a new explanation instead. From the moment nomadic humans first settled down until the aftermath of the Second World War, our species has confronted repeated crises that we could only survive by changing our behavior. As McCullough argues, these choices weren’t enabled by an evolved moral sense, but with moral invention — driven not by evolution’s dictates but by reason.

Beyond Revenge: The Evolution of the Forgiveness Instinct

Why is revenge such a pervasive and destructive problem? How can we create a future in which revenge is less common and forgiveness is more common? Psychologist Michael McCullough argues that the key to a more forgiving, less vengeful world is to understand the evolutionary forces that gave rise to these intimately human instincts and the social forces that activate them in human minds today. Drawing on exciting breakthroughs from the social and biological sciences, McCullough dispenses surprising and practical advice for making the world a more forgiving place.


Forgiveness: Theory, Research and Practice

Bringing together a distinguished array of researchers and scholars, this volume reviews the breadth of current knowledge on the psychology of forgiveness. In addition to presenting cutting-edge theory and research, the book outlines crucial issues that must be addressed to advance the state of the science in years to come. The first section provides a historical and conceptual overview, examining definitional problems and giving special attention to religious and cultural influences on how forgiveness is understood and experienced. The biological, developmental, social, and personality foundations of forgiveness are then explored. The final section covers applications in clinical research and practice, including guidelines for studying and applying forgiveness-based strategies in psychotherapy, counseling, and interventions to promote health. This volume will be of interest to a broad interdisciplinary audience of researchers, educators, students, and practicing professionals.


The Psychology of Gratitude

Gratitude, like other positive emotions, has inspired many theological and philosophical writings, but it has inspired very little vigorous, empirical research. In an effort to remedy this oversight, this volume brings together prominent scientists from various disciplines to examine what has become known as the most-neglected emotion. The volume begins with the historical, philosophical, and theoretical foundations of gratitude, then presents the current research perspectives from social, personality, and developmental psychology, as well as from primatology, anthropology, and biology. The volume also includes a comprehensive, annotated bibliography of research on gratitude. This work contributes a great deal to the growing positive psychology initiative and to the scientific investigation of positive human emotions. It will be an invaluable resource for researchers and students in social, personality, and developmental, clinical, and health psychology, as well as to sociologists and cultural anthropologists.


Handbook of Religion and Health

What effect does religion have on physical and mental health? In answering this question, this book reviews and discusses research on the relationship between religion and a variety of mental and physical health outcomes, including depression and anxiety; heart disease, stroke, and cancer; and health related behaviors such as smoking and substance abuse. The authors examine the positive and negative effects of religion on health throughout the life span, from childhood to old age. Based on their findings, they build theoretical models illustrating the behavioral, psychological, social, and physiological pathways through which religion may influence health. The authors also review research on the impact of religious affiliation, belief, and practice on the use of health services and compliance with medical treatment. In conclusion, they discuss the clinical relevance of their findings and make recommendations for future research priorities. Offering the first comprehensive examination of its topic, this volume is an indispensable resource for research scientists, health professionals, public policy makers, and anyone interested in the relationship between religion and health.


Research on Altruism and Love: An Annotated Bibliography of Major Studies in Psychology, Sociology, Evolutionary Biology, and Theology

Research on Altruism and Love is a compendium of annotated bibliographies reviewing literature and research studies on the nature of love. An essay introduces each of the annotated bibliographies. A variety of literature either directly related to science-and-love issues or supporting literature for those issues is covered in the Religious Love Interfaces with Science section. This annotated bibliography is unique in that it approaches the field from a decidedly religious perspective. It includes classical expositions of love that continue to influence contemporary scholars, including Platos’ work on eros, the work and words of Jesus, Aristotle, Augustine of Hippo, Martin Luther, Kierkegaard, and Ghandi, among others. The contemporary discussion includes Anders Nygren’s theological arguments in his classic, Agape and Eros; Pitirim Sorokin; and others. An issue that often emerges in this literature is the question of the nature and definition of love. A second annotated bibliography features current empirical research in the field of Personality and Altruism, with a focus on social psychology. Among the topics covered are the altruistic personality, altruistic behavior, empathy, helping behavior, social responsibility, and volunteerism. Methodologies are diverse, and studies include experiments, local and national surveys, naturalistic observation, and combinations of these. The Evolutionary Biology annotated bibliography covers the most significant works on altruism and love in the field of biology and evolutionary psychology. The fourth and final annotated bibliography in this volume is entitled Sociology of Faith-Based Volunteerism. Here the focus is on literature on the interface of helping behavior and religious organizations, as well as major pieces on voluntary associations.
