Beginning with the belief that the study of leadership belongs to all and to no one in particular, the author offers twenty-seven stable and unchanging elements for the study of leadership, and collects them under four themes: context, shared purpose, language, and human agency. He (a) argues that the rational interest in making our world a better place cuts across all academic disciplines/boundaries, (b) grounds the quest for an integrated theory of leadership in the Desire for Shared Agreement, and (c) offers the possibility that this Desire as a Governing Standard can potentially unite the multiple approaches to leadership studies.
