This paper examines the nature of organizational leadership from the perspective of common sense principles. The principles are established by means of a Thomistic metaphysics of the One and the Many, i.e., the Thomistic teaching of the opposition between Unity and Multiplicity. It is this Thomistic metaphysical philosophical science that studies the distinct kind (genus) of an organization and its specific common sense principles of organizational leadership. This common sense leadership is a harmonious blending of psychology, ethics and operational behavior.
