Exploring the concept of virtuous humility helps to highlight paths of human flourishing. Yet humility is difficult to study because it is often stereotyped as shame or self-abasement, it tends to defy uniform conceptualization across contexts and cultures, definitions are difficult to justify, and operationalizing humility challenges standard approaches in the social sciences. The present work develops a theory of interactive humility as openness to others (IHO) by foregrounding interaction and interpersonal context. IHO theory builds on a previously published theory of humility as the absence of the vices of pride and tests the new proposal against research done in conjunction with l'Arche communities. Conceptual networks from core l'Arche texts showed that openness ranks second among concepts most similar to humility (0.85), while humility ranks first for openness. These networks support the view that humility as openness in the context of l'Arche is primarily interactive and interpersonal, rather than intellectual.
