Humility is often defined by what it is not; as the antithesis to various vices such as pride, arrogance, conceit, or vanity. This negative definition leaves open the possibility of some underlying characteristic or trait that influences the formation of this virtue. Homo amans lays out the classic theological triad of faith, hope, and love as a natural inclination in humanity. This chapter explores one aspect of this triad, love, as a possible underlying characteristic or trait that uniquely informs the formation of the virtue of humility: specifically, love as altruistic concern for the other that puts them ahead or before the self. Contemporary psychological studies of humility demonstrate a connection between this virtue and altruistic concern for the other. Altruistic concern becomes a part of moral schemas that greatly influence moral behavior and are the basis for the development of moral identity. Holocaust rescuers demonstrate that moral schemas, which contain altruistic concern as a primary component of their view of the world, cultivate a moral identity that makes rescuing a consequence of their self-identity and naturally leads to humility about their actions.
