This book opens a new field within business science: management philosophy. This discipline gives a thorough and critical foundation of a theory of management and leadership beyond any talk of value-based management, and ethical accounting . It presents an uncompromising picture of the real leader through a set of leadership virtues, focusing on human duties, not on human rights. The book demonstrates that only through philosophy it is possible to establish a genuine science of management, overcoming the pressures of functionalism, opportunism and pragmaticism, inherent in the hyper-modern corporation shaped by high-tech and information advantages.Management or Leadership.- Dialogue or Metalogue.- The Virtues of Leadership.- Space and Time in Management.
