This integrating essay reviews three books, Inclusive Leadership, written with a co-author, Brian Hirsh, Ronin and Revolutionaries and The Ronin Age. The essay explores the idea of the internal revolutionary, or Ronin, and examines various models of leadership and influence that have characterised organisational thinking over many years, and the challenges that Ronin pose for leadership and effective management. It also explores the extent to which the focus on innovative thinking is increased by the growing importance of knowledge as a key competitive issue.
