<P>The second half of the twentieth century witnessed the emergence of the most complex global organizations ever known. Taking a complexity theory perspective, this book explores the key factor that sustains them: leadership.</P> <P>The book examines how leadership is currently understood primarily from a systems based perspective, as an attribute of the individual, the leadership role being to articulate values, missions and visions and then persuade others to adhere to them. It argues for a new view of ethics as co-created through identity and difference, representing the end of 'business ethics' as we know it today. Areas considered include:</P> <UL> <LI>risk and conflict</LI> <LI>spontaneity and motivation.</LI></UL> <P>In the past we have focused on the choices of individual leaders. In today's highly complex organizations we are now coming to understand the nature of leadership as self-organizing and, as such, closely linked to ethics. This means that we can no longer understand ethics simply as centered rational choice in planning and action. </P>
