This readable book is a clear statement of a managerial theory that is scientific in outlook and approach, humanistic and democratic in spirit. The new leadership which the author felt to be most appropriate for the modern organization is closely reflected in his style of thought and writing: persuasive, not prescriptive; direct, not circuitous; organized, but not rigidly systematized; intensely human, not detached. He points out that the most effective, and the most equitable, course of leadership is to satisfy the higher needs of workers on all levels - for self-respect, initiative, recognition of competence - and he calls for heterogeneity and flexibility in organization.
