Book excerpt: Can feeling genuinely sorry enable an important healing experience? Can relieving the weight of guilt restore a general sense of self-worth? Can an individual's dawning awareness give birth to feelings of remorse; perhaps even to acts of repentance? The concepts of betrayal, vengeance and forgiveness have long been a major part of religious doctrine throughout the world. However, only in recent times has the impact of these emotions become of interest to those involved in psychological study. In The Psychology of Feeling Sorry, Peter Randall links contemporary psychological research with religious teachings and doctrine that have provided spiritual guidance for hundreds of years. Illustrated with explanatory narratives, Randall fuses religious precepts with psychological theory concerning one of the least understood but most common of human emotions; feeling bad about one's 'sins'. Using an eclectic approach Randall explores how much of what is believed within the domain of faith is now supported by modern psychological research. This book will be of interest not only to those with religious beliefs, but to psychologists, psychotherapists, students, and anyone with an interest in the intersection of psychology, psychotherapy, and theology.
