Available in paperback for the first time, Gareth Griffith's book provides a comprehensive critical account of the political ideas of one of the most influential commentators of the twentieth century.With close reference to a range of Shaw's texts, from the Fabian tracts to the plays, Gareth Griffith draws out the central theoretical messages of Shaw's engagement with politics.

It will be central reading for anyone seeking to understand Shaw's life, and literary and political writings, or the development of political thinking in this century, or the problems and potential inherent in socialism.
