Self-transcendence as a concept is increasingly found in leadership literature—yet in diverse ways. It is this diversity that serves as the motivation for the current article in which we develop a comprehensive and coherent conceptualization of self-transcendence for leadership research. We demonstrate that self-transcendence is the cognitive orientation of accepting something other than one's self to be of highest worth. We show that this something, which is greater than the self, may take four different forms: other people, social collectives, moral principles and ideals, or metaphysical beings.
