The preface to this new edition of Leadership: The Inner Side of Greatness began by saying that interest in philosophy in business has grown since the first edition appeared a decade ago. In fact, philosophy in business has itself grown. Analyses based on the Leadership Diamond model have deepened and become more sophisticated—and more capable of getting us closer and faster to the bottom line. This chapter presents recent analyses of several current business issues where philosophy can help. For more impact on practical applications, we have changed the order of presentation, beginning with ethics and ending with vision. First, however, we briefly revisit some fundamentals of the model.
