This chapter connects the previous discussions on development and ethics to the popular theory of authentic leadership. It critically reviews the established social-scientific models, arguing that their conceptualization of authenticity and its link to ethics is insufficient. Building on philosophical insights, particularly from a Kantian perspective, the chapter redefines authenticity as a continuous process of self-authentication. This process is grounded in a moral conscience that is fundamentally interactional, not introspective, and finds its expression in a social context defined by tolerance and transparency.
