The collapse of leadership theories

After having published an article on servant leadership and another on transformational leadership I became aware that several researchers had examined these theories in order to determine similarities and differences between them. Their purpose was to understand these theories. A theory can indeed be understood in the way in which it differs from other theories. All knowledge is conceptually mediated and thus concept-dependent. Concepts, moreover, are required to be well defined. The clarification of different concepts, their content, how they related to one another, is in itself an important task in research. Ultimately, servant leadership and transformational leadership must be based on different concepts in order to make a comparison between them a meaningful scholarly endeavour.
