Best known for introducing the idea of ecology to the left, and for first positing that a liberatory society would also have to be an ecological society, Murray Bookchin, over the course of several decades, developed the basic components of "libertarian municipalism" - how to create free cities. Written in short, to-the-point chapters, this book presents an introductory overview and sketches the historical and philosophical context in which these ideas are grounded. Substantial material on the practical question of creating and organizing a new municipal movement toward such democratic cities is included. Bookchin has generously provided the lengthy interview that makes up the last third of the book.
