The book’s premise is that the theories taught in management schools are based on unacknowledged philosophical perspectives that are significant not so much for what they explain, but for what they assume. Rarely made explicit, these perspectives cannot be reconciled, with the result that the study of management has been dominated by contradictions and internecine intellectual warfare. However, the ability critically to analyze these diverse perspectives is essential to practicing and aspiring managers if they are to evaluate expert opinion. Moreover, since management is primarily an exercise in communication, managing is impossible in the darkness of an imprecise language, in the absence of moral references, or in the senseless outline of a world without intellectual foundations. Managing is a prime example of applied philosophy.
