Murray Bookchin was one of the most important radical thinkers of the twentieth century. This is his final book, completed just before he died in 2006. It is the first book to comprehensively explain his political ideas. In the 1960s Murray Bookchin introduced the concept of ecology into progressive politics, and he is widely regarded as the foremost theorist of the green and anarchist movements. Bookchin argued that capitalism and the nation state, as well as oppressive social relations in general, must be abolished if we are to have a rational and ecological society. According to Bookchin, we must fundamentally remake society along ecological lines, based on principles of confederation, humanism, non-hierarchy and direct democracy. In a time when the left is highly defensive, Bookchin's ideas of social ecology present a strong vision of an alternative society. With today's huge improvements in communications, his bold ideas are increasingly practical and, faced with ecological catastrophe, they are increasingly necessary. This is a must-read for students of political theory and anti-globalisation activists.
