Moral engine model: conceptualizing moral injury as a wound to the self caused by rupturing of defining and sustaining emotional attachments
Abstract
A theory is elaborated illuminating the nature of moral injury based on evolutionary biology and psychoanalytic object-relations and self psychology, which explains how the betrayal of a moral trust can produce not only the negative moral emotions and losses of social and spiritual engagement characteristic of moral injury, but also the entire spectrum of adverse peri-and post-traumatic stress states. After stating the rationale for a few starting assumptions, three premises on which this theory is built are articulated, and their empirical support reviewed. The first premise is that morality is innate, evolving in vertebrates over a half billion years to enable the formation and evolution of cultures. The second premise is that pre-wired moral capacities comprise four concurrent moral modes serving a hierarchy of four moral imperatives: survive, be respected, love and belong, and seek the greater good. The third premise is that prosocial moral behavior continuously depends on the availability of secure and nourishing emotional attachments of three types (valued, valuing, and kindred), and that the rupture of an important emotional attachment may cause a sudden loss of the functional integrity of the self, manifested as dissociation and the fragmentation of experience and behavior. A theory of personhood called the Moral Engine Model, based on these three premises, is then described, articulating the relationship between the availability of defining and sustaining emotional attachments and one’s ability to become the best version of oneself and to contribute to the greater good through love, work, play, and creation. Two clinical vignettes are offered as frameworks for exploring the effects of betrayals of trust by oneself or someone else on the availability of diverse defining and sustaining, internal and external emotional attachments. Moral mapping is introduced as a graphical tool for visualizing changes in emotional attachments caused by moral injury traumas. Finally, a few thoughts about the possible application of the model to clinical treatment are offered.
